                                                                               1
 
                          A BRIEF PREVIEW OF THE FUNDS
 
             WHAT ARE THE GOALS OF THE ONE GROUP EQUITY FUNDS?
             The Funds are designed for a variety of investment objectives,
             including total return, capital appreciation, current income,
             and long-term capital growth. Each Fund pursues a different
             objective and involves different risks. Please read about each
             Fund before investing.
 
             WHAT ARE THE FUNDS' INVESTMENT STRATEGIES?

             The Funds normally will invest in a variety of equity
             securities, including common stock. The Funds also may invest
             in debt securities and preferred stocks which are convertible
             into common stock. Most of the Funds may invest in securities
             of foreign issuers.
 
             WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUNDS?
             Equity securities such as those in which the Funds may invest
             are more volatile and carry more risk than some other forms of
             investment. Accordingly, as with all equity investments, you
             may lose money by investing in the Funds. The Funds may invest
             in derivative securities. These securities may expose the
             Funds to special risks. In addition, investments in foreign
             securities may expose the Funds to risks that are different
             from investments in U.S. securities. For more information
             about risks, please read "More About the Funds" and
             "Investment Risks."
 
             WHAT CLASSES OF SHARES ARE AVAILABLE?
             The Funds currently offer four classes of Shares: Class A,
             Class B, Class C and Fiduciary Class. Class A, Class B and
             Class C shares are offered to the general public. Fiduciary
             Class shares are offered to institutional investors, including
             affiliates of BANC ONE CORPORATION and any bank, depository
             institution, insurance company, pension plan or other
             organization authorized to act in fiduciary, advisory, agency,
             custodial or similar capacities. The section called "How To Do
             Business With The One Group" will provide more information.
             Fiduciary Class shares are not available to Individual
             Retirement Accounts ("IRA").
 
             HOW DO I PURCHASE AND REDEEM SHARES?
   
             You may buy and redeem shares of the Funds on any day that the
             Funds are open for business. Class C shares are not available
             for purchase in all of the Funds. Purchase and redemption
             procedures are explained in greater detail in "How To Do
             Business With The One Group." For additional information, call
             The One Group Services Company at 1-800-480-4111.
    
 
             HOW ARE DIVIDENDS PAID?
   
             Generally, dividends are declared on the last business day of
             each month and are distributed periodically on the first
             business day of each month. The One Group International Equity
             Index Fund, however, distributes dividends annually. Any
             capital gains are distributed at least annually. Distributions
             are paid in additional shares of the same class unless you
             elect to take the payment in cash. For a more detailed
             discussion of dividends, see "Dividend Policies."
    
 
             WHO MANAGES THE FUNDS?
             Banc One Investment Advisors Corporation ("Banc One Investment
             Advisors"), an indirect subsidiary of BANC ONE CORPORATION,
             serves as the advisor of the Funds. Banc One Investment
             Advisors is paid a fee for its services. Independence
             International Associates, Inc. (the "Sub-Advisor") serves as
             Sub-Advisor to the International Equity Index Fund. The
             Sub-Advisor's fees are paid by Banc One Investment Advisors. A
             more detailed discussion regarding Banc One Investment
             Advisors, its services and compensation can be found in the
             Prospectus under the headings "The Advisor" and "Expense
             Summary." Additional information regarding the Sub-Advisor is

THE ONE GROUP(R)
 
ASSET ALLOCATION FUND

[ICON] INVESTMENT OBJECTIVE
The Fund seeks to provide total return while preserving capital.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in a combination of stocks, fixed income securities and money
market instruments. Banc One Investment Advisors will regularly review the
Fund's asset allocations and vary them over time to favor investments which they
believe will provide the most favorable total return. In making asset allocation
decisions, Banc One Investment Advisors will evaluate projections of risk,
market and economic conditions, volatility, yields and expected return. Because
the Fund seeks total return over the long term, Banc One Investment Advisors
will not attempt to time the market. Rather, asset allocation shifts will be
made gradually over time.
 
[ICON] PORTFOLIO SECURITIES
The Fund normally will invest between 40% and 75% of its total assets in all
types of equity securities, including the stock of both large and small
capitalization companies, as well as growth and value securities. Up to 20% of
the equities held by the Fund may be foreign securities, including American
Depository Receipts. Between 25% and 60% of the Fund's total assets will be
invested in fixed income securities, including bonds, notes, and other debt
securities. The balance of the Fund's total assets will be invested in money
market instruments. For a list of all the securities in which the Fund may
invest, please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities, which may increase or decrease in value.
As a result, the value of your investment in the Fund may increase or decrease
in value. The Fund also will invest in fixed income securities. The value of
these securities will change in response to interest rate changes and other
factors. This is especially true to the extent the Fund invests in debt
securities in the lowest investment grade category. Such securities have
speculative characteristics. Before you invest, please read "More About the
Funds" and "Investment Practices."
 
[ICON] FUND MANAGEMENT
Scott Grimshaw is the Manager of the fixed income portion of the Fund, having
served in that position since November, 1996. He has been employed as a research
analyst for Banc One Investment Advisors or its affiliates since 1988.
 
   Since May 1, 1997, Dan Kapusta has served as Manager of the equity portion of
the Fund. Mr. Kapusta has been an equity analyst with Banc One Investment
Advisors since 1992. Before joining Banc One Investment Advisors, Mr. Kapusta
worked for Robert W. Baird, Inc. in Milwaukee, Wisconsin as an equity analyst.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from the redemption amounts paid by
    wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .65% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(6) Total Operating Expenses have been revised to reflect fee waivers. Without
    the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.40% for Class A shares, 2.05% for Class B
    shares, 2.05% for Class C shares and 1.05% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
 
LARGE COMPANY GROWTH FUND

[ICON] INVESTMENT OBJECTIVE
The Fund seeks long-term capital appreciation and growth of income by investing
primarily in equity securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests primarily in equity securities of large, well-established
companies. The weighted average capitalization of companies in which the Fund
invests normally will exceed the market median capitalization of the Standard &
Poor's 500 Composite Stock Price Index ("S&P 500).*
 
[ICON] PORTFOLIO SECURITIES
   
The Fund normally invests at least 65% of its total assets in the equity
securities of companies described above, including common stock, warrants and
rights to buy common stocks. The remainder of the Fund's total assets will be
invested in nonconvertible fixed income securities, options and futures,
repurchase agreements, and securities issued by the U.S. government and its
agencies and instrumentalities. For daily cash management purposes, the Fund may
invest in repurchase agreements and cash equivalents. For a list of all the
securities in which the Fund may invest, please read "Investment Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities, which may increase or decrease in value.
As a result, the value of your investment in the Fund may increase or decrease
in value. The Fund also will invest in fixed income securities. The value of
these securities will change in response to interest rate changes and other
factors. This is especially true to the extent the Fund invests in debt
securities with speculative characteristics. Before you invest, please read
"More About the Funds" and "Investment Practices."
 
[ICON] FUND MANAGEMENT
The Fund is managed by a team of portfolio managers, research analysts, and
other investment management professionals. Each team member makes
recommendations about the securities in the Fund. The research analysts provide
in-depth industry analysis and recommendations, while the portfolio managers
determine strategy, industry weightings, Fund holdings, and cash positions.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(5) Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
    would be 1.35% for Class A shares.

 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
 
LARGE COMPANY VALUE FUND

[ICON] INVESTMENT OBJECTIVE
The Fund seeks capital appreciation with the incidental goal of achieving
current income by investing primarily in equity securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in equity securities of large capitalization companies that are
believed to be selling below their long-term investment values. The weighted
average capitalization of companies in which the Fund invests normally will
exceed the market median capitalization of the Standard & Poor's 500 Composite
Stock Price Index ("S&P 500).* The Fund also may invest in the stock of
companies which have "breakup values" well in excess of current market values or
which have uniquely undervalued corporate assets.
 
[ICON] PORTFOLIO SECURITIES
   
The Fund normally invests at least 65% of its total assets in the equity
securities of companies described above, including common stocks and debt
securities and preferred stock that is convertible to common stock. A portion of
the Fund's assets will be held in cash equivalents. For a list of all the
securities in which the Fund may invest, please read "Investment Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities, which may increase or decrease in value.
As a result, the value of your investment in the Fund may increase or decrease
in value. Before you invest, please read "More About the Funds" and "Investment
Practices."
 
[ICON] FUND MANAGEMENT
The Fund is managed by a team of portfolio managers, research analysts, and
other investment management professionals. Each team member makes
recommendations about the securities in the Fund. The research analysts provide
in-depth industry analysis and recommendations, while the portfolio managers
determine strategy, industry weightings, Fund holdings, and cash positions.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(5) Without the voluntary 12b-1 fees, Total Operating Expenses would be 1.34%
    for Class A shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
 
GROWTH OPPORTUNITIES FUND

[ICON] INVESTMENT OBJECTIVE
The Fund seeks growth of capital and secondarily, current income by investing
primarily in equity securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in securities that have the potential to produce above-average
earnings growth per share over a one-to-three year period. Typically, the Fund
acquires shares of established companies with a history of above-average growth,
as well as those companies expected to enter periods of above average growth.
Not all the securities purchased by the Fund will pay dividends. The Fund also
invests in smaller companies in emerging growth industries.
 
[ICON] PORTFOLIO SECURITIES
The Fund normally invests at least 80% of its total assets in equity securities,
including common stocks and debt securities and preferred stocks that are
convertible to common stock. A portion of the Fund's assets will be held in cash
equivalents. For a list of all the securities in which the Fund may invest,
please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities which may increase or decrease in value.
Therefore, the value of your investment in the Fund may increase or decrease in
value. Also, the stocks of smaller companies may be subject to greater risks
than those of larger companies. Before you invest, please read "More About the
Funds" and "Investment Practices."
 
[ICON] FUND MANAGEMENT
The Fund is managed by a team of portfolio managers, research analysts, and
other investment management professionals. Each team member makes
recommendations about the securities in the Fund. The research analysts provide
in-depth industry analysis and recommendations, while the portfolio managers
determine strategy, industry weightings, Fund holdings, and cash positions.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from the redemption amounts paid by
    wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(5) Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
    would be 1.35% for Class A shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

Class B shares automatically convert to Class A shares after eight (8) years.
Therefore, the "10 years" examples above reflect this conversion.
 
These examples are designed to assist you in understanding the various costs and

THE ONE GROUP(R)

INTERNATIONAL EQUITY INDEX FUND
- -------------------------------
[ICON] INVESTMENT OBJECTIVE
The Fund seeks to provide investment results that correspond to the aggregate
price and dividend performance of the securities in the MSCI EAFE GDP Index.*
 
[ICON] INVESTMENT STRATEGY
   
The Fund attempts to track the capital performance and dividend income of the
Index by investing in a representative portion of the stocks which match as
closely as possible the characteristics of the stocks which comprise the Index.
The Fund also will invest in stock index futures. The Fund will attempt to
achieve a correlation between the performance of its portfolio and that of the
MSCI EAFE GDP Index of at least 0.90, without taking into account expenses.
Perfect correlation would be 1.00.
    
 
[ICON] PORTFOLIO SECURITIES
The Fund normally invests at least 65% of its total assets in foreign equity
securities, consisting of common stocks (including American Depository Receipts)
and preferred stocks, securities convertible to common stock (provided they are
traded on an exchange or over-the-counter), warrants and receipts. No more than
10% of the Fund's assets will be held in cash or cash equivalents. The Fund may
invest up to 10% of its net assets in securities of emerging international
markets such as Mexico, Chile and Brazil, either directly through local
exchanges, through publicly traded closed-end country funds, or through "passive
foreign investment companies." A substantial portion of the Fund's assets will
be denominated in foreign currencies. For a list of all the securities in which
the Fund may invest, please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities which may increase or decrease in value.
Therefore, the value of your investment in the Fund may increase or decrease in
value. Because the Fund's investments are tied to an index, fluctuations in the

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from the redemption amounts paid by
    wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(5) Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
    would be 1.31% for Class A shares.
 












 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
 
DISCIPLINED VALUE FUND
- ----------------------
[ICON] INVESTMENT OBJECTIVE
The Fund seeks capital appreciation with the secondary goal of achieving current
income by investing primarily in equity securities.
 
[ICON] INVESTMENT STRATEGY
The Fund primarily invests in the equity securities of companies with
below-market average price-to-earnings and price-to-book value ratios. The Fund
considers the issuer's soundness and earnings prospects. If Banc One Investment
Advisors determines that a company's fundamentals are declining or that the
company's ability to pay dividends has been impaired, it likely will eliminate
the Fund's holding of the company's stock.
 
[ICON] PORTFOLIO SECURITIES
The Fund normally invests at least 80% of its total assets in equity securities,
including common stocks, debt securities, and preferred stocks that are
convertible into common stocks. A portion of the Fund's assets will be held in
cash equivalents. For a list of all the securities in which the Fund may invest,
please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities which may increase or decrease in value.
Therefore, the value of your investment in the Fund may increase or decrease in
value. Before you invest, please read "More About the Funds" and "Investment
Practices."
 
[ICON] FUND MANAGEMENT
The Fund is managed by a team of portfolio managers, research analysts, and
other investment management professionals. Each team member makes
recommendations about the securities in the Fund. The research analysts provide
in-depth industry analysis and recommendations, while the portfolio managers
determine strategy, industry weightings, Fund holdings, and cash positions.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from the redemption amounts paid by
    wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(5) Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
    would be 1.35% for Class A shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

Class B shares automatically convert to Class A shares after eight (8) years.
Therefore, the "10 years" examples above reflect this conversion.
 
These examples are designed to assist you in understanding the various costs and
expenses that may be directly or indirectly paid by investors in the Fund. THESE

THE ONE GROUP(R)
 
EQUITY INDEX FUND
- -----------------
[ICON] INVESTMENT OBJECTIVE
The Fund seeks investment results that correspond to the aggregate price and
dividend performance of securities in the S&P 500 Index.*
 
[ICON] INVESTMENT STRATEGY
   
The Fund invests primarily in stocks included in the S&P 500 Index and,
secondarily in stock index futures. Banc One Investment Advisors will seek to
achieve a correlation between the performance of the Fund and that of the S&P
500 Index. To implement this strategy, Banc One Investment Advisors generally
selects stocks in the order of their weightings in the S&P 500 Index beginning
with the heaviest weighted stocks. The Fund will attempt to achieve a
correlation between the performance of its portfolio and that of the S&P 500
Index of at least 0.95, without taking into account expenses. Perfect
correlation would be 1.00.
    
 
[ICON] PORTFOLIO SECURITIES
   
The percentage of a stock that the Fund holds will be approximately the same
percentage that the stock represents in the S&P 500 Index. In addition, the Fund
may hold up to 10% of its net assets in cash or cash equivalents. For a list of
all the securities in which the Fund may invest, please read "Investment
Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities, which may increase or decrease in value.
Therefore, the value of your investment in the Fund may increase or decrease in
value. Because the Fund's investments are tied to an index, fluctuations in the
index will affect the value of your investment in the Fund. Before you invest,
please read "More About the Funds" and "Investment Risks."
 
[ICON] FUND MANAGEMENT
Michael D. Weiner has been the Manager of the Fund since November 1994. Mr.
Weiner also serves as the Managing Director of Equity Research for Banc One
Investment Advisors. Before joining Banc One Investment Advisors, Mr. Weiner
served as the Director of Research and Head of U.S. Equities for the Dupont
Pension Fund Investment Company of Wilmington, Delaware from 1986 to 1994.

(1) If you buy or sell shares through an account with a Shareholder Servicing
    Agent, you may be charged separate transaction fees by the Shareholder
    Servicing Agent. In addition, a $7.00 charge is deducted from the redemption
    amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .30% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(6) Without the fee waiver, other expenses would be .35% for all classes.
(7) Without the voluntary reduction of Investment Advisory, 12b-1 fees and other
    expenses, Total Operating Expenses would be 1.00% for Class A shares, 1.65%
    for Class B shares, 1.65% for Class C shares and .65% for Fiduciary Class
    shares.

THE ONE GROUP(R)
 
INCOME EQUITY FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks current income through regular payment of dividends with the
secondary goal of achieving capital appreciation by investing primarily in
equity securities.
 
[ICON] INVESTMENT STRATEGY
The Fund attempts to keep its yield above the S&P 500 Index* by investing in
common stocks of corporations which regularly pay dividends, as well as stocks
with favorable long-term fundamental characteristics. Continued payment of
dividends cannot be assured. Because achieving yield is the primary
consideration in selecting securities, stocks of companies that are out of favor
in the financial community may also be purchased.
 
[ICON] PORTFOLIO SECURITIES
   
The Fund normally invests at least 65% of its total assets in the equity
securities of companies described above, including common stocks, debt
securities, and preferred stocks that are convertible into common stocks. A
portion of the Fund's assets will be held in cash equivalents. For a list of all
the securities in which the Fund may invest, please read "Investment Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities, which may increase or decrease in value.
Therefore, the value of your investment in the Fund may increase or decrease in
value. Before you invest, please read "More About the Funds" and "Investment
Practices."
 
[ICON] FUND MANAGEMENT
R. Lynn Yturri has served as manager of the Fund since July, 1993. Mr. Yturri
has 25 years of investment management experience. Prior to 1993, Mr. Yturri

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(5) Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
    would be 1.36% for Class A shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
 
VALUE GROWTH FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks long term capital growth and growth of income with a secondary
objective of providing a moderate level of current income.
 
[ICON] INVESTMENT STRATEGY
The Fund invests primarily in common stocks, debt securities, preferred stocks,
convertible securities, warrants, and other equity securities of overlooked or
undervalued companies that have the potential for earnings growth over time.
Although the Fund expects to invest in securities that pay a moderate level of
income, it may also invest in non-income producing securities if the potential
for capital growth or future income appears promising. Because the Fund seeks
return over the long term, Banc One Investment Advisors will not attempt to time
the market.
 
[ICON] PORTFOLIO SECURITIES
The Fund normally invests at least 65% of its total assets in the securities
described in "Investment Strategy." Up to 35% of its total assets may be
invested in U.S. Government Securities, other investment grade fixed income
securities, cash, and cash equivalents. For a list of all the securities in
which the Fund may invest, please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in equity securities which may increase or decrease in value.
As a result, your investment in the Fund may increase or decrease in value. The
Fund also will invest in fixed income securities. The value of these securities
will change in response to interest rate changes and other factors. This is
especially true to the extent that the Fund invests in debt securities with
speculative characteristics. Before you invest, please read "More About the
Funds" and "Investment Risks."
 
[ICON] FUND MANAGEMENT
   
Michael D. Weiner has been the Manager of the Fund since February, 1996. Since
1994, Mr. Weiner also has served as manager of the Equity Index Fund. Mr. Weiner
also serves as the Managing Director of Equity Research for Banc One Investment
Advisors. Before joining Banc One Investment Advisors, Mr. Weiner served as the
Director of Research and Head of U.S. Equities for the Dupont Pension Fund
Investment Company of Wilmington, Delaware from 1986 to 1994.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(5) Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
    would be 1.40% for Class A shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

Class B shares automatically convert to Class A shares after eight (8) years.
Therefore, the "10 years" examples above reflect this conversion.
 
These examples are designed to assist you in understanding the various costs and

THE ONE GROUP(R)
 
SMALL CAPITALIZATION FUND
[ICON] INVESTMENT OBJECTIVE
 
The Fund seeks long-term capital growth primarily by investing in a portfolio of
equity securities of small capitalization and emerging growth companies.

[ICON] INVESTMENT STRATEGY
 
The Fund invests primarily in common stocks, debt securities, preferred stocks,
convertible securities, warrants, and other equity securities of small
capitalization companies. Generally, Banc One Investment Advisors selects a
portfolio of companies with a market capitalization equivalent to the median
market capitalization of the S&P Small-Cap 600 Index*, although the Fund may
occasionally hold securities of companies with larger capitalizations if doing
so contributes to the Fund's investment objective. This Fund was formerly called
The One Group Gulf South Growth Fund.

[ICON] PORTFOLIO SECURITIES
 
The Fund invests at least 65% of its total assets in the securities described in
"Investment Strategy." Up to 35% of its total assets may be invested in U.S.
Government Securities, other investment grade fixed income securities, cash, and
cash equivalents. For a list of all the securities in which the Fund may invest,
please read "Investment Practices."

[ICON] RISK CONSIDERATIONS
 
The Fund invests in equity securities which may increase or decrease in value.
As a result, your investment in the Fund may increase or decrease in value.
Also, smaller companies may be subject to greater business risks than larger
companies. Before you invest, please read "More About the Funds" and "Investment
Risks."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A shares.
(5) Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
    would be 1.41% for Class A shares.
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

PORTFOLIO QUALITY
- ----------------------------------------------------
 
The Funds only purchase securities that meet certain rating criteria.
 
- - >If the Funds invest in municipal bonds, the bonds must be rated as investment
   grade.
 
- - >Other municipal securities, such as tax-exempt commercial paper, notes and
   variable rate demand obligations, must be rated in one of the two highest
   investment grade categories at the time of investment.
 
- - >Corporate bonds generally will be rated in one of the three highest
   investment grade categories.
 
- - >Banc One Investment Advisors reserves the right to invest in corporate bonds
   which present attractive opportunities and are rated in the lowest investment
   grade category. These corporate bonds may be riskier than higher rated bonds.
 
If the securities are unrated, Banc One Investment Advisors must determine that
they are of comparable quality to rated securities. Banc One Investment Advisors
will look at a security's rating at the time of investment. For more information
about ratings, please see "Description of Ratings" in the Appendix.
 
ILLIQUID INVESTMENTS
- ----------------------------------------------------
 
Each Fund may invest up to 15% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by The One Group Board of Trustees in determining whether an
investment is illiquid.
 
SPECIAL RISK
CONSIDERATIONS
- ----------------------------------------------------
 
DERIVATIVES: Some of the Funds invest in securities that are considered to be
derivatives. These securities may be more volatile than other investments. These
include:
 
- - >options, futures contracts, and options on futures contracts
 
- - >warrants
 
- - >mortgage-backed securities, including collateralized mortgage obligations and
   Real Estate Mortgage Investment Conduits (CMOs and REMICs) and stripped
   mortgage-backed securities (IOs and POs)
 
- - >asset-backed securities
 
   
- - >swap, cap and floor transactions
    
 
- - >new financial products
 
- - >currency forwards
 
- - >structured instruments
 
Derivatives may be riskier than traditional investments.
 
SMALL CAPITALIZATION COMPANIES: Investments in smaller, younger companies may be
riskier than investments in larger, more established companies. These companies
may be more vulnerable to changes in economic conditions, specific industry
conditions, market fluctuations, and other factors effecting the profitability
of other companies. Because economic events may have a greater impact on smaller
companies, there may be a greater and more frequent fluctuation in their stock
price. This may cause frequent and unexpected increases or decreases in the
value of your investment.
 
   
FIXED INCOME SECURITIES: Investments in fixed income securities (for example,
bonds) will increase or decrease in value based on changes in interest rates. If
rates increase, the value of a Fund's investments generally declines. On the
other hand, if rates fall, the value of the investments generally increases. The
value of your investment in a Fund will increase and decrease as the value of a
Fund's investments increase and decrease. While securities with longer duration
and maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment.
    
 
INDEX FUNDS: An index fund's investment objective is to track the performance of
a specified index. Therefore, securities may be purchased, retained and sold by
an index fund at times when an actively managed fund would not do so. As a
result, you can expect greater risk of loss (and a correspondingly greater
prospect of gain) from changes in the value of securities that are heavily
weighted in the index than would be the case if the funds were not fully
invested in such securities. Because of this, an index fund's share price can be
volatile and you should be able to handle sudden, and sometimes substantial,
fluctuations in the value of your investment.
 
INTERNATIONAL FUNDS: Investments in foreign securities involve risks different
from investments in U.S. securities. For more details, see "Investment
Practices" and "Investment Risks." Because of these risk factors, the share
price of the International Equity Index Fund is expected to be volatile, and you
should be able to sustain sudden, and sometimes substantial, fluctuations in the
value of your investment.

                     HOW TO DO BUSINESS WITH THE ONE GROUP
 
                                                                              33
 
PURCHASING
FUND SHARES
- ----------------------------------------------------
 
WHERE CAN I BUY SHARES?
 
You may purchase Fund shares from the following sources:
 
- - The One Group Services Company, and
 
- - Shareholder Servicing Agents. These include investment advisors, brokers,
  financial planners, banks, insurance companies, retirement or 401(k) plan
  sponsors, or other intermediaries. Shares purchased this way will be held for
  you by the Shareholder Servicing Agent.
 
WHEN CAN I BUY SHARES?
 
- - Purchases may be made on any business day. This includes any day that the
  Funds are open for business, other than weekends and the following holidays:
  New Years Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
  Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas.
 
- - Purchase requests received by The One Group Services Company before 4 p.m.
  Eastern Standard Time ("EST") will be effective that day.
 
- - Purchase orders may be cancelled by the Fund's Custodian, State Street Bank
  and Trust Company, if it does not receive "federal funds" by 4:00 p.m. EST (i)
  on the business day after the order is placed if you are buying Fiduciary
  Class shares, and (ii) on the third business day if you are purchasing Class
  A, Class B or Class C shares.
 
- - If your shares are held by a Shareholder Servicing Agent, it is the
  responsibility of the Shareholder Servicing Agent to send your purchase or
  redemption order to the Fund. Your Shareholder Servicing Agent may have an
  earlier cut-off time for purchase and redemption requests.
 
- - The One Group Services Company can reject a purchase order if it does not
  think that it is in the best interests of a Fund and/or its shareholders to
  accept the order.
 
- - Shares are electronically recorded. Therefore, certificates will not be
  issued.
 
WHAT KIND OF SHARES CAN I BUY?
 
The One Group offers the following classes of shares:
 
- - Class A, Class B and Class C shares are available to the general public.
 
- - Fiduciary Class shares are available to institutional investors and any
  organization authorized to act in a fiduciary, advisory, custodial or agency
  capacity. We will refer to these entities as "Intermediaries."
 
- - If you intend to hold your shares for six or more years, Class B shares may be
  appropriate for you. If you intend to hold your shares for less than six
  years, you may want to consider Class A or Class C shares.
 
   
  The One Group Fund Direct IRA. The One Group offers a retirement plan and, in
  1998, will offer an education plan. These plans allow participants to defer
  taxes while their retirement and education savings grow. The education IRA
  requires a minimum investment of $500. Call The One Group Services Company at
  1-800-480-4111 for an Adoption Agreement.
    
 
HOW MUCH DO SHARES COST?
 
- - Shares are sold at net asset value ("NAV") plus a sales charge, if any.
 
- - Each class of shares in each Fund has a different NAV. This is primarily
  because each class has different distribution expenses.
 
- - NAV per share is calculated by dividing the total market value of a Fund's
  investments and other assets allocable to a class (minus class expenses) by
  the number of outstanding shares in that class.
 
- - A Fund's NAV changes every day. NAV is calculated each business day at 4:00
  p.m. EST.
 
HOW DO I OPEN AN ACCOUNT?
 
1. Read the prospectus carefully, and select the Fund or Funds most appropriate
   for you.
 
2. Decide how much you want to invest.
 
   - The minimum initial investment is $1,000 ($100 for employees of BANC ONE
     CORPORATION and its affiliates).
 
   - Subsequent investments must be at least $100 ($25 for employees of BANC ONE
     CORPORATION and its affiliates).
 
   - You may purchase no more than $250,000 of Class B shares at one time.
 
   - The One Group Services Company may waive these minimums.
 
3.Complete the Account Application Form. Be sure to sign up for all of the
  Account privileges that you plan to take advantage of. Doing so now means that
  you will not have to complete additional paperwork later.
<PAGE>   36
 
34
 
4.Send the completed application and a personal check (unless you choose to pay
  by wire or bank transfer) payable to "The One Group" to:
 
  State Street Bank and Trust Company
  c/o The One Group
  P.O. Box 8500
  Boston, MA 02266-8500
 
   Contributions to Fund Direct IRAs should be made payable to "State Street
   Bank and Trust Company for the Benefit of (your name)."
 
5. All checks should be in U.S. dollars. Third party checks will not be
   accepted. Redemptions from a Fund will not be permitted for ten (10) calendar
   days if purchases are made by check or under the Systematic Investment Plan
   (see below).
 
6. If you purchase shares through a Shareholder Servicing Agent, you may be
   required to complete additional forms or follow additional procedures. You
   should contact your Shareholder Servicing Agent regarding purchases,
   exchanges and redemptions.
 
7. If you have any questions, contact your Shareholder Servicing Agent or call
   The One Group Services Company at 1-800-480-4111.
 
CAN I PURCHASE SHARES OVER THE TELEPHONE?
 
Yes. Simply select this option on your Account Application Form and then:
 
- - Contact your Shareholder Servicing Agent or The One Group Services Company at
  1-800-480-4111 to relay your purchase instructions.
 
- - Send a personal check made payable to "The One Group" to State Street Bank and
  Trust Company (see address above), authorize a bank transfer or initiate a
  wire transfer.
 
- - The One Group uses reasonable procedures to confirm that instructions given by
  telephone are genuine. These procedures include recording telephone
  instructions and asking for personal identification. If these procedures are
  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
   
- - You may revoke your right to make purchases over the telephone by sending a
  letter to:
    
 
  State Street Bank and Trust Company
  c/o The One Group
  P.O. Box 8500
  Boston, MA 02266-8500
 
CAN I AUTOMATICALLY INVEST ON A
SYSTEMATIC BASIS?
 
Yes. After your Account is established, you may purchase additional Class A,
Class B and Class C shares by making automatic monthly investments from your
bank account. The minimum initial investment is still $1,000, but minimum
automatic additions are only $25. The One Group Services Company may waive these
minimums. To establish a Systematic Investment Plan:
 
- - Select the "Systematic Investment Plan" option on the Account Application
  Form.
 
- - Provide the necessary information about the bank account from which your
  investments will be made.
 
- - Shares purchased under a Systematic Investment Plan may not be redeemed for
  ten (10) calendar days.
 
- - The One Group currently does not charge for this service, but may impose a
  charge in the future. However, your bank may impose a charge for debiting your
  bank account.
 
   
- - You may revoke your right to make systematic investments by sending a letter
  to:
    
 
  State Street Bank and Trust Company
  c/o The One Group
  P.O. Box 8500
  Boston, MA 02266-8500
 
CONVERSION FEATURE
 
Your Class B shares automatically convert to Class A shares after eight years
(measured from the end of the month in which they were purchased).
 
- - After conversion, your shares will be subject to the lower distribution and
  shareholder servicing fees charged on Class A shares.
 
- - You will not be assessed any sales charges or fees for conversion of shares,
  nor will you be subject to any tax.
 
- - Because the share price of the Class A shares may be higher than that of the
  Class B shares at the time of conversion, you may receive fewer Class A
  shares; however, the dollar value will be the same.
 
- - If you have exchanged Class B shares of one Fund for Class B shares of
  another, the time you held the shares in each Fund will be added together.
 
SALES CHARGES
- ----------------------------------------------------
 
   
The One Group Services Company compensates Shareholder Servicing Agents who sell
shares of The One Group. Compensation comes from sales charges, 12b-1 fees and
payments by The One Group Services Company from its own resources. The One Group
Services Company, at its own expense, also will provide promotional incentives
in the form of travel expenses, lodging and bonuses to licensed individuals who
sell shares of the Funds, as well as vacation trips (including lodging at luxury
resorts), tickets to entertainment events, and merchandise.

</TABLE>
 
The One Group Services Company pays a commission of 4.00% of the original
purchase price to Shareholder Servicing Agents who sell Class B shares.
 
 CLASS C SHARES
 
Class C shares are offered at NAV, without any up-front sales charge. However,
if you redeem your shares within one year of the purchase date, you will be
assessed a CDSC as follows:
 
<TABLE>
<CAPTION>
                          CDSC AS A % OF DOLLAR
YEARS SINCE PURCHASE     AMOUNT SUBJECT TO CHARGE
<S>                      <C>                     
         0-1                       1.00%
  After first year                  none
</TABLE>
 
Shareholder Servicing Agents selling Class C shares receive a commission of
1.00% of the original purchase price from The One Group Services Company.
 
How the CDSC is Calculated
 
- - The Fund assumes that all purchases made in a given month were made on the
  first day of the month.
 
- - The CDSC is based on the current market value or the original cost of the
  shares, whichever is less.
 
- - A sales charge is not imposed on increases in NAV above the initial purchase
  price, nor is a sales charge assessed on shares acquired through reinvestment
  of dividends or capital gains distributions.
 
- - To keep your CDSC as low as possible, the Fund first will redeem any shares in
  your account that carry no CDSC, starting with Class A Shares. After that, the
  Fund will redeem the shares you have held for the longest time and thus have
  the lowest CDSC.
<PAGE>   38

12B-1 FEES
 
12b-1 fees are paid by The One Group to The One Group Services Company as
compensation for its services and expenses. The One Group Services Company in
turn pays all or part of the 12b-1 fee to Shareholder Servicing Agents that sell
shares of The One Group.
 
- - The 12b-1 fees vary by share class as follows:
 
   1. Class A shares pay a 12b-1 fee of .35% of the average daily net assets of
      the Fund, which is currently being waived to .25%.
 
   2. Class B and Class C shares pay a 12b-1 fee of 1.00% of the average daily
      net assets of the Fund. This will cause expenses for Class B and Class C
      shares to be higher and dividends to be lower than for Class A shares.
 
   3. There are no 12b-1 fees for Fiduciary Class shares.
 
- - 12b-1 fees, together with the CDSC, help The One Group Services Company sell
  Class B and Class C shares without an "up-front" sales charge by defraying the
  costs of advancing brokerage commissions and other expenses paid to
  Shareholder Servicing Agents.
 
- - The One Group Services Company may use up to .25% of the fees for shareholder
  servicing and up to .75% for distribution. During the last fiscal year, The
  One Group Services Company received 12b-1 fees totaling .25% and 1.00% of the
  average daily net assets of Class A and Class B shares, respectively.
 
- - The One Group Services Company may pay 12b-1 fees to its affiliates and to
  Banc One Investment Advisors and its affiliates (or any sub-advisor) for
  brokerage and other agency transactions.
 
SALES CHARGE
REDUCTIONS
AND WAIVERS
- ----------------------------------------------------
 
REDUCING YOUR CLASS A SALES CHARGES
 
There are several ways you can reduce the sales charges you pay on Class A
shares:
 
1. Right of Accumulation: You may add the market value of any Class A, Class B
   or Class C shares of a Fund (except a money market fund) that you (and your
   spouse and minor children) already own to the amount of your next Class A
   purchase for purposes of calculating the sales charge. An Intermediary also
   may take advantage of this option.
 
2. Letter of Intent: With an initial investment of $2,000, you may purchase
   Class A shares of one or more funds over the next 13 months and pay the same
   sales charge that you would have paid if all shares were purchased at once. A
   percentage of your investment will be held in escrow until the full amount
   covered by the Letter of Intent has been invested.
 
To take advantage of the accumulation privilege or letter of intent, complete
the appropriate section of your fund application, or contact your investment
representative. To determine if you are eligible for the accumulation privilege,
contact The One Group Services Company at 1-800-480-4111. These programs may be
terminated or amended at any time.

2. Acquired in exchange for other Fund shares if a comparable sales charge has
   been paid for the exchanged shares.
 
3. Bought by officers, directors or trustees, retirees and employees (and their
   spouses and immediate family members) of:
 
   - The One Group.

     subsidiaries and affiliates.
 
4. Bought by:

   - Accounts as to which a bank or broker-dealer charges an asset allocation
     fee, provided the bank or broker-dealer has an agreement with The One Group
     Services Company.
 
   - Retirement and deferred compensation plans and trusts used to fund those
     plans, including, but not limited to, those defined in sections 401(a),
     403(b) or 457 of the Internal Revenue Code and "rabbi trusts."

   - Shareholder Servicing Agents who have a dealer arrangement with The One
     Group Services Company, who place trades for their own accounts or for the
     accounts of their clients and who charge a management, consulting or other
     fee for their services, as well as clients of such Shareholder Servicing
     Agents who place trades for their own accounts if the accounts are linked
     to the master account of such Shareholder Servicing Agent.
    
 
5. Bought with proceeds from the sale of Fiduciary Class shares of a Fund of The
   One Group or acquired in an exchange of Fiduciary Class shares of a Fund for
   Class A shares of the same Fund, but only if the purchase is made within 60
   days of the sale or distribution.
 
6. Bought with proceeds from the sale of shares of a mutual fund (other than a
   fund of The One Group) for which a sales charge was paid, but only if the
   purchase is made within 60 days of the sale or distribution.
 
7. Bought in an IRA with the proceeds of a distribution from an employee benefit
   plan, but only if the purchase is made within 60 days of the sale or
   distribution and, at the time of the distribution, the employee benefit plan
   had plan assets invested in a Fund of The One Group.
 
8. Bought with assets of The One Group.

EXCHANGING
FUND SHARES
- ----------------------------------------------------
 
WHAT ARE MY EXCHANGE PRIVILEGES?
 
You may make the following exchanges:
 
- - Fiduciary Class shares of a Fund may be exchanged for Class A shares of that
  Fund or for Class A or Fiduciary Class shares of another Fund of The One
  Group.
 
- - Class A shares of a Fund may be exchanged for Fiduciary Class shares of that
  Fund or for Class A or Fiduciary Class shares of another Fund of The One
  Group, but only if you are eligible to purchase those shares.

- - Class B shares of a Fund may be exchanged for Class B shares of another Fund
  of The One Group.

- - Class C shares of a Fund may be exchanged for Class C shares of another Fund
  of The One Group.
<PAGE>   40
 
38
 
The One Group does not charge a fee for this privilege. In addition, The One
Group may change the terms and conditions of your exchange privileges upon 60
days written notice.
 
WHEN ARE EXCHANGES PROCESSED?
 
Exchanges are processed the same business day they are received, provided:
 
- - State Street Bank and Trust Company receives the request by 4:00 p.m., EST.
 
- - You have provided The One Group with all of the information necessary to
  process the exchange.
 
- - You have received a current prospectus of the Fund or Funds in which you wish
  to invest.
 
- - You have contacted your Shareholder Servicing Agent, if necessary.
 
DO I PAY A SALES CHARGE ON AN EXCHANGE?
 
Generally, you will not pay a sales charge on an exchange. However:
 
- - You will pay a sales charge if you own Fiduciary Class shares of a Fund and
  you want to exchange those shares for Class A shares, unless you qualify for a
  sales charge waiver (see above).
 
- - You will pay a sales charge if you bought Class A shares of a Fund:
 
   1. That does not charge a sales charge and you want to exchange them for
      shares of a Fund that does, in which case you would pay the sales charge
      applicable to the Fund into which you are exchanging.
 
   2.That charged a lower sales charge than the Fund into which you are
     exchanging, in which case you would pay the difference between that Fund's
     sales charge and all other sales charges you have already paid.
 
- - If you exchange Class B or Class C shares of a Fund, you will not pay a sales
  charge at the time of the exchange, however:
 
   1. Your new Class B or Class C shares will be subject to the higher CDSC of
      either the Fund from which you exchanged, the Fund into which you
      exchanged, or any Fund from which you previously exchanged.
 
   2. The current holding period for your exchanged Class B or Class C shares is
      carried over to your new shares.
 
ARE EXCHANGES TAXABLE?
 
Generally:
 
- - An exchange between classes of shares of the same Fund is not taxable.
 
- - An exchange between Funds is considered a sale and generally results in a
  capital gain or loss for Federal income tax purposes.
 
- - You should talk to your tax advisor before making an exchange.
 
ARE THERE LIMITS ON EXCHANGES?
 
Yes. The exchange privilege is not intended as a way for you to speculate on
short term movements in the market. Therefore:
 
- - To prevent disruptions in the management of the Funds, The One Group limits
  excessive exchange activity.
 
- - Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
  REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH PERIOD.
 
   
- - In addition, The One Group reserves the right to reject any exchange request
  (even those that are not excessive) if the Fund reasonably believes that the
  exchange will result in excessive transaction costs or otherwise adversely
  affect other shareholders.

<PAGE>   41
 
                                                                              39

   2. the redemption is payable to the shareholder of record; and
 
   3.the redemption check is mailed to the shareholder at the record address.
 
- - On the Account Application Form you may elect to have the redemption proceeds

   1. a designated commercial bank; or
    
 
   2.State Street Bank and Trust Company or your Shareholder Servicing Agent.

- - If you own Class B or Class C shares and the Fund receives your redemption
  request by 4:00 p.m. EST, you will receive that day's NAV, minus the amount of
  any applicable CDSC.
 
CAN I REDEEM BY TELEPHONE?

- - Call your Shareholder Servicing Agent or State Street Bank and Trust Company
  at 1-800-480-4111 to relay your redemption request.

  the risk of loss.
 
- - REDEMPTIONS FROM YOUR IRA ACCOUNT MAY NOT BE MADE BY TELEPHONE.

  Form.
 
- - Specify the amount you wish to receive and the frequency of the payments.
 
- - You may designate a person other than yourself as the payee.
 
- - There is no charge for this service.
 
- - If you select this option, please keep in mind that:
 
   1. It may not be in your best interest to buy additional Class A shares while
      participating in a Systematic Withdrawal Plan. This is because Class A
      shares have an up-front sales charge.
 
   2. If you own Class B or Class C shares, you or your designated payee may
      receive systematic payments provided the payments are limited to no more
      than 10% of your account value annually, measured from the date the
      redemption request is received.
 
   3. If you are age 70 1/2, you may elect to receive payments to the extent
      that the payment represents a minimum required distribution from an IRA or
      other qualifying retirement plan.
 
   4. If the amount of the systematic payment exceeds the income earned by your
      account since the previous payment under the Systematic Withdrawal Plan,
      payments will be made by redeeming some of your shares. This will reduce
      the amount of your investment.
 
ADDITIONAL INFORMATION REGARDING REDEMPTIONS
 
- - All redemptions will be for cash.
 
- - If you redeem shares for which you paid by check, and The One Group has not
  yet received payment on the check, The One Group will delay forwarding your
  redemption proceeds for 10 or more days until payment has been collected from
  your bank.
 
- - Because of the high cost of handling small investments, The One Group will
  automatically redeem shares in accounts which, because of shareholder
  redemptions, have values of less than $1,000. No sales charges will be
  assessed and you will be given 60 days to make additional investments in the
  Fund to increase the value of your account to at least $1,000.
 
- - The One Group may suspend your ability to redeem, or will redeem your shares
  involuntarily, when it seems appropriate to do so in light of its
  responsibilities under the Federal securities laws. The Statement of
  Additional Information offers more details about this process.

VOTING RIGHTS
- ----------------------------------------------------
 
The Funds do not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change a Fund's fundamental investment objective, or approve an
investment advisory contract.
 
As a Fund shareholder, you have one vote for each share that you own. Each Fund,
and each class of shares within each Fund, vote separately on matters relating
solely to that Fund or class, or which affect that Fund or class differently.
However, all shareholders will have equal voting rights on matters that affect
all shareholders equally.
 
BANC ONE CORPORATION (100 East Broad Street, Columbus, Ohio, 43271), through its
affiliates, may be deemed for purposes of the Investment Company Act of 1940, to
control the Funds. This is because as of August 5, 1997, BANC ONE CORPORATION or
its affiliates possessed the power to vote substantially all of the Fiduciary
Class shares of the Funds.
 
DIVIDEND POLICIES
- ----------------------------------------------------
 
DIVIDENDS
 
The Funds generally declare dividends on the last business day of each month.
Dividends are distributed on the first business day of the next month. Capital
gains, if any, for all Funds are distributed at least annually.
 
The Funds pay dividends and distributions on a per-share basis. This means that
the value of your shares will be reduced by the amount of the payment. If you
purchase shares shortly before the record date for a dividend or the
distribution of capital gains, you will pay the full price for the shares and
receive some portion of the price back as a taxable dividend or distribution.
 
Dividends payable on Fiduciary Class shares will be more than those payable on
other classes of shares. This is because Class A, Class B and Class C shares
have higher distribution expenses.
 
DIVIDEND REINVESTMENT
 
You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund and class, unless you have
elected to take such payment in cash. The price of the shares is the NAV
determined immediately following the dividend record date. Reinvested dividends
and distributions receive the same tax treatment as dividends and distributions
paid in cash.
 
If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8500, Boston, MA
02266-8500, at least 15 days prior to the distribution. The change is effective
upon receipt by State Street.
 
SPECIAL DIVIDEND RULES FOR CLASS B SHARES
 
Class B shares received as dividends and capital gains distributions will be
accounted for separately. Each time any Class B shares (other than those in the
sub-account) convert to Class A shares, a percentage of the Class B shares in
the sub-account will also convert to Class A shares. (See "Conversion Feature.")
 
TAX TREATMENT
OF THE FUNDS
- ----------------------------------------------------
 
TAX STATUS OF THE FUND
 
Each Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Funds qualify, as they have in the past, they will
pay no federal income tax on the earnings they distribute to shareholders.
 
TAX TREATMENT
OF SHAREHOLDERS
- ----------------------------------------------------
 
TAXATION OF SHAREHOLDER TRANSACTIONS
 
A sale, exchange, or redemption of Fund shares generally will produce either a
taxable gain or a loss. You are responsible for any tax liabilities generated by
your transactions.
 
TAXATION OF DISTRIBUTIONS
 
Each Fund will distribute substantially all of its net investment income
(including net short-term capital gains) on at least an annual basis. Dividends
you receive from a Fund, whether reinvested or received in cash, will be taxable
to you. Dividends from a Fund's net investment income will be taxable as
ordinary income and dividends from a Fund's long-term capital gains will be
taxable to you as such, regardless of how long you have held the shares.
 
Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid the previous December.

                                                                              41
 
TAXATION OF RETIREMENT PLANS
 
Distributions by the Funds to qualified retirement plans will not be taxable.
However, if shares are held by a plan that ceases to qualify for tax-exempt
treatment or by an individual who has received shares as a distribution from a
retirement plan, the distributions will be taxable to the plan or individual as
described in "Taxation of Distributions." If you are considering purchasing
shares with qualified retirement plan assets, you should consult your tax
advisor for a more complete explanation of the Federal, state, local and (if
applicable) foreign tax consequences of making such an investment.
 
TAX INFORMATION
 
The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Funds provide you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Funds or their shareholders.

                    ORGANIZATION AND MANAGEMENT OF THE FUNDS
 
42
 
THE FUNDS
Each Fund is a series of The One Group, an open-end management investment
company. The One Group currently consists of 40 separate Funds. Ten of the Funds
are described in this prospectus; the other Funds are described in separate
prospectuses. Each Fund described in this prospectus is diversified. Each Fund
is supervised by the Board of Trustees.
 
THE BOARD OF TRUSTEES
 
The Trustees oversee the management and administration of the Funds. The
Trustees are responsible for making major decisions about each Fund's investment
objectives and policies, but delegate the day-to-day administration of the Funds
to the officers of The One Group.
 
THE ADVISOR
 
Banc One Investment Advisors makes the day-to-day investment decisions for the
Funds and continuously reviews, supervises and administers the Funds' investment
programs. Banc One Investment Advisors has served as investment advisor to The
One Group since 1993. Prior to that time, The One Group was advised by
affiliates of Banc One Investment Advisors. In addition to The One Group, Banc
One Investment Advisors serves as investment advisor to other mutual funds and
individual, corporate, charitable and retirement accounts. As of June 30, 1997,
Banc One Investment Advisors, an indirect, wholly-owned subsidiary of BANC ONE
CORPORATION, managed over $47 billion in assets.
 
For the fiscal year ended June 30, 1997, the Funds paid advisory fees at the
following rates:

INVESTMENT RISKS
- ----------------------------------------------------
 
Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities held by the Funds may fluctuate, as will the value of
your investment in the Funds. Certain investments are more susceptible to these
risk than others.
 
- - CREDIT RISK. The risk that the issuer of a security, or the counterparty to a
  contract, will default or otherwise become unable to honor a financial
  obligation. Credit risk is generally higher for non-investment grade
  securities. The price of a security can be adversely affected prior to actual
  default as its credit status deteriorates and the probability of default
  rises.
 
   
- - LEVERAGE RISK. The risk associated with securities or practices that multiply
  small index or market movements into large changes in value. Leverage is often
  associated with investments in derivatives, but also may be embedded directly
  in the characteristics of other securities.
    
 
   - HEDGED. When a derivative (a security whose value is based on another
     security or index) is used as a hedge against an opposite position that the
     fund also holds, any loss generated by the derivative should be
     substantially offset by gains on the hedged investment, and vice versa.
     While hedging can reduce or eliminate losses, it can also reduce or
     eliminate gains. Hedges are sometimes subject to imperfect matching between
     the derivative and underlying security, and there can be no assurance that
     a Fund's hedging transactions will be effective.
 
   - SPECULATIVE. To the extent that a derivative is not used as a hedge, the
     fund is directly exposed to the risks of that derivative. Gains or losses
     from speculative positions in a derivative may be substantially greater
     than the derivative's original cost.
 
- - LIQUIDITY RISK. The risk that certain securities may be difficult or
  impossible to sell at the time and the price that would normally prevail in
  the market. The seller may have to lower the price, sell other securities
  instead or forego an investment opportunity, any of which could have a
  negative effect on fund management or performance. This includes the risk of
  missing out on an investment opportunity because the assets necessary to take
  advantage of it are tied up in less advantageous investments.
 
- - MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
  to produce the intended result. This includes the risk that changes in the
  value of a hedging instrument will not match those of the asset being hedged.
  Incomplete matching can result in unanticipated risks.
 
- - MARKET RISK. The risk that the market value of a security may move up and
  down, sometimes rapidly and unpredictably. These fluctuations may cause a
  security to be worth less than the price originally paid for it, or less than
  it was worth at an earlier time. Market risk may affect a single issuer,
  industry, sector of the economy or the market as a whole. There is also the
  risk that the current interest rate may not accurately reflect existing market
  rates. For fixed income securities, market risk is largely, but not
  exclusively, influenced by changes in interest rates. A rise in interest rates
  typically causes a fall in values, while a fall in rates typically causes a
  rise in values. Finally, key information about a security or market may be
  inaccurate or unavailable. This is particularly relevant to investments in
  foreign securities.
 
- - POLITICAL RISK. The risk of losses attributable to unfavorable governmental or
  political actions, seizure of foreign deposits, changes in tax or trade
  statutes, and governmental collapse and war.
 
- - FOREIGN INVESTMENT RISK. The risk associated with higher transaction costs,
  delayed settlements, currency controls and adverse economic developments. This
  also includes the risk that fluctuations in the exchange rates between the
  U.S. dollar and foreign currencies may negatively affect an investment.
  Adverse changes in exchange rates may erode or reverse any gains produced by
  foreign currency denominated investments and may widen any losses. Exchange
  rate volatility also my affect the ability of an issuer to repay U.S. dollar
  denominated debt, thereby increasing credit risk.
 
- - PRE-PAYMENT RISK. The risk that the principal repayment of a security will
  occur at an unexpected time, especially that the repayment of a mortgage or
  asset-backed security occurs either significantly sooner or later than
  expected. Changes in pre-payment rates can result in greater price and yield
  volatility. Pre-payments generally accelerate when interest rates decline.
<PAGE>   50
 
48
 
  When mortgage and other obligations are pre-paid, a Fund may have to reinvest
  in securities with a lower yield. Further, with early prepayment, a Fund may
  fail to recover any premium paid, resulting in an unexpected capital loss.
 
- - TAX RISK. The risk that the issuer of the securities will fail to comply with
  certain requirements of the Internal Revenue Code, which would cause adverse
  tax consequences.
 
- - REGULATORY RISK. The risk associated with Federal and state laws which may
  restrict the remedies that a mortgage lender has when a borrower defaults on
  mortgage loans. These laws include restrictions on foreclosures, redemption
  rights after foreclosure, Federal and state bankruptcy and debtor relief laws,
  restrictions on "due on sale" clauses, and state usury laws.
 
INVESTMENT POLICIES
- ----------------------------------------------------
 
Each Fund's investment objective and the investment policies summarized below
are fundamental. This means that they cannot be changed without the consent of a
majority of the outstanding shares of the Funds. The full text of the
fundamental policies can be found in the Statement of Additional Information.
 
Each Fund may not:
 
1. Purchase an issuer's securities if as a result more than 5% of its total
   assets would be invested in the securities of that issuer or the Fund would
   own more than 10% of the outstanding voting securities of that issuer. This
   does not include securities issued or guaranteed by the United States, its
   agencies or instrumentalities, and repurchase agreements involving these
   securities. This restriction applies with respect to 75% of a Fund's total
   assets.
 
2. Concentrate its investments in the securities of one or more issuers
   conducting their principal business in a particular industry or group of
   industries. This does not include obligations issued or guaranteed by the
   U.S. government or its agencies and instrumentalities and repurchase
   agreements involving such securities.
 
3. Make loans, except that a Fund may (i) purchase or hold debt instruments in
   accordance with its investment objective and policies; (ii) enter into
   repurchase agreements; and (iii) engage in securities lending.
 
The One Group Equity Index Fund may not:
 
1. Invest more than 10% of its total assets in securities issued or guaranteed
   by the United States, its agencies or instrumentalities.
 
Additional investment policies can be found in the Statement of Additional
Information.
 
TEMPORARY DEFENSIVE POSITION
 
Sometimes Banc One Investment Advisors decides that the Funds should temporarily
be invested in cash and cash equivalents. Cash equivalents include:
 
- - Securities issued by the U.S. Government, its agencies and instrumentalities
 
- - Repurchase Agreements
 
- - Certificates of Deposit
 
- - Bankers' Acceptances
 
- - Commercial Paper (rated in one of the two highest rating categories)
 
- - Variable Rate Master Demand Notes
 
- - Bank Money Market Deposit Accounts
 
All of the Funds (other than the International Equity Index Fund and the Equity
Index Fund) may temporarily invest up to 100% of their total assets in cash and
cash equivalents. The Equity Index Fund may temporarily invest only 10% of its
total assets in cash and cash equivalents, while the International Equity Index
Fund may invest up to 20% of its total assets in debt securities issued or
guaranteed by foreign governments or any of their political subdivisions,
agencies or instrumentalities, or by supranational issuers rated in one of the
three highest rating categories.
 
While the Funds are engaged in a temporary defensive position, they will not be
pursuing their investment objectives. Therefore, the Funds will pursue a
temporary defensive position only when market conditions warrant.
 
PORTFOLIO TURNOVER
 
Portfolio turnover may vary greatly from year to year, as well as within a
particular year.
 
Higher portfolio turnover rates will likely result in higher transaction costs
to the Funds and may result in additional tax consequences to you. The portfolio
turnover rate for each Fund for the fiscal year ended June 30, 1997 is shown on
the Financial Highlights.

DESCRIPTION OF RATINGS
 
The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.
 
Unrated securities will be treated as non-investment grade securities unless
Banc One Investment Advisors determines that such securities are the equivalent
of investment grade securities. Securities that have received different ratings
from more than one agency are considered investment grade if at least one agency
has rated the security investment grade.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
 
DUFF & PHELPS CREDIT RATING CO. ("DUFF")
 
    D-1+ Highest certainty of timely payment. Short-term liquidity, including
         internal operating factors and/or access to alternative sources of
         funds, is outstanding and safety is just below risk-free U.S. Treasury
         obligations.
 
     D-1 Very high certainty of timely payment. Liquidity factors are excellent
         and supported by good fundamental protection factors. Risk factors are
         minor.
 
    D-1- High certainty of timely payment. Liquidity factors are strong and
         supported by good fundamental protection factors. Risk factors are very
         small.
 
STANDARD & POOR'S CORPORATION ("S&P")
 
     A-1 Highest category of commercial paper. Capacity to meet financial
         commitment is strong. Obligations designated with a plus sign (+)
         indicate that capacity to meet financial commitment is extremely
         strong.
 
     A-2 Issues somewhat more susceptible to adverse effects of changes in
         circumstances and economic conditions than obligations in higher rating
         categories. However, the capacity to meet financial commitments is
         satisfactory.
 
FITCH'S INVESTORS SERVICE, L.P. ("FITCH")
 
    F-1+ Exceptionally strong credit quality. Strongest degree of assurance for
         timely payment.
 
     F-1 Very strong credit quality. Assurance of timely payment is only
         slightly less in degree than issues rated F-1+.
 
     F-2 Good credit quality. Satisfactory degree of assurance for timely
         payment, but the margin of safety is not as good as for issues assigned
         F-1+ and F-1 ratings.
 
IBCA LIMITED ("IBCA")
 
      A1 Highest capacity for timely repayment. Those issues rated A1+ possess a
         particularly strong credit feature.
 
      A2 Satisfactory capacity for timely repayment although such capacity may
         be susceptible to adverse changes in business, economic or financial
         conditions.
 
MOODY'S INVESTORS SERVICE ("MOODY'S")
 
 PRIME-1 Superior ability for repayment.
 
 PRIME-2 Strong ability for repayment.
 
DESCRIPTION OF BANK RATINGS
 
MOODY'S
 
These ratings represent Moody's opinion of a bank's intrinsic safety and
soundness.
 
       A These banks possess exceptional intrinsic financial strength. Typically
         they will be major financial institutions with highly valuable and
         defensible business franchises, strong financial fundamentals, and a
         very attractive and stable operating environment.
 
       B These banks possess strong intrinsic financial strength. Typically,
         they will be important institutions with valuable and defensible
         business franchises, good financial fundamentals, and an attractive and
         stable operating environment.
 
       C These banks possess good intrinsic financial strength. Typically, they
         will be institutions with valuable and defensible business franchises.
         These banks will demonstrate either acceptable financial fundamentals
         within a stable operating environment, or better than average financial
         fundamentals within an unstable operating environment.

S&P
 
S&P's credit rating is a current opinion of an obligor's overall financial
capacity (its creditworthiness) to pay its financial obligation.
 
    Aaa The highest rating assigned by S&P. The obligor's capacity to meet its
        financial commitment on the obligation is extremely strong.
 
     Aa The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A The obligation is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than obligations in
         higher rated categories. However, the obligor's capacity to meet its
         financial commitment on the obligation is still strong.
 
DESCRIPTION OF INSURANCE RATINGS
 
MOODY'S
 
These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.
 
    Aaa Insurance companies rated in this category offer exceptional financial
        security. While the financial strength of these companies is likely to
        change, such changes as can be visualized are most unlikely to impair
        their fundamentally strong position.
 
      Aa These insurance companies offer excellent financial security. Together
         with the Aaa group, they constitute what are generally known as high
         grade companies. They are rated lower than Aaa companies because
         long-term risks appear somewhat larger.
 
       A Insurance companies rated in this category offer good financial
         security. However, elements may be present which suggest a
         susceptibility to impairment sometime in the future.
 
S&P
 
S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.
 
    AAA This is the highest rating assigned by S&P. The obligor's capacity to
        meet its financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A An obligation rated A is somewhat more susceptible to the adverse
         effects of changes in circumstances and economic conditions than
         obligations in higher rated categories. However, the obligor's capacity
         to meet its financial commitment on the obligation is still strong.
 
DESCRIPTION OF CORPORATE/
MUNICIPAL BOND RATINGS
 
S&P
 
Investment Grade
 
    AAA The highest rating. The rating indicates an extremely strong capacity to
        meet its financial commitment.
 
     AA Differs from AAA issues only in a small degree. The obligor's capacity
        to meet its financial commitment is very strong.
 
       A These bonds are somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than debt in higher
         rated categories. However, capacity to meet its financial commitment on
         the obligation is still strong.
 
    BBB Exhibits adequate protection parameters. However, adverse economic
        conditions or changing circumstances are more likely to lead to a
        weakened capacity to meet its financial commitment on the obligation.
 
Speculative Grade
 
     BB Less vulnerable to non-payment than other speculative issues. However,
        these bonds face major ongoing uncertainties or exposure to adverse
        business, financial or economic conditions which could lead to
        inadequate capacity to meet financial commitment on the obligation.
 
       B More vulnerable to non-payment than obligations rated BB, but currently
         has the capacity to meet its financial commitment on the obligation.
         Adverse business, financial or economic conditions will likely impair
         capacity or willingness to meet its financial commitment on the
         obligation.
 
    CCC Currently vulnerable to non-payment, and is dependent upon favorable
        business, financial, and economic conditions to meet its financial
        commitment on the obligation. In the event of adverse busi-
<PAGE>   53
 
                                                                              51
 
        ness, financial, or economic conditions, they are not likely to have the
        capacity to meet its financial commitment on the obligation.
 
      CC Currently highly vulnerable to non-payment.
 
       C This rating may be used to cover a situation where a bankruptcy
         petition has been filed, or similar action has been taken, but payments
         on this obligation are being continued.
 
       D Bonds in payment default.
 
Ratings from AA to CCC may be modified by a plus (+) or minus (-) to show
relative standing within the major rating categories.
 
MOODY'S
 
Investment Grade
 
    Aaa Best quality. They carry the smallest degree of investment risk and are
        generally referred to as "gilt edged." Interest payments are protected
        by a large, or an exceptionally stable, margin and principal is secure.
 
      Aa High quality by all standards. Margins of protection may not be as
         large as in Aaa securities, fluctuation of protective elements may be
         greater, or there may be other elements present that make the long-term
         risks appear somewhat larger than in Aaa securities.
 
       A These bonds possess many favorable investment attributes and are to be
         considered as upper-medium grade obligations. Factors giving security
         to principal and interest are considered adequate, but elements may be
         present which suggest a susceptibility to impairment sometime in the
         future.
 
    Baa These bonds are considered medium-grade obligations (i.e., they are
        neither highly protected nor poorly secured). Interest payments and
        principal security appear adequate for the present but certain
        protective elements may be lacking or may be characteristically
        unreliable over any great length of time. Such bonds lack outstanding
        investment characteristics and in fact have speculative characteristics
        as well.
 
Non-Investment Grade
 
      Ba These bonds have speculative elements; their future cannot be
         considered as well assured. The protection of interest and principal
         payments may be very moderate and thereby not well safeguarded during
         good and bad times over the future.
 
       B These bonds lack the characteristics of a desirable investment (i.e.,
         potentially low assurance of timely interest and principal payments or
         maintenance of other contract terms over any long period of time may be
         small).
 
     Caa Bonds in this category have poor standing and may be in default. These
         bonds carry an element of danger with respect to principal and interest
         payments.
 
      Ca Speculative to a high degree and could be in default or have other
         marked shortcomings. Ca is the lowest rating.
 
DESCRIPTION OF MUNICIPAL NOTE RATINGS
 

MOODY'S

MIG1 &   Short-term municipal securities rated MIG1 or VMIG1 are of the best
 VMIGX1  quality. They have strong protection from established cash flows,
         superior liquidity support or demonstrated broad-based access to the
         market for refinancing.

MIG2 &   These Short-term municipal securities are of high quality. Margins of
 VMIG2   protection are ample although not so large as in the preceding group.

 
MIG3 &   Favorable quality. All security elements are accounted for, but the
 VMIG3   undeniable strength of the preceding grades is lacking. Liquidity and
         cash flow protection may be narrow and marketing access for
         refinancing is likely to be less well established.
                                     
                                     
                                      
                                      
                                     
                                     
 
S&P
 
An S&P note rating reflects the liquidity concerns and market access risks
unique to notes. Notes due in three years or less will likely receive a note
rating. Notes maturing beyond three years will most likely receive a long-term
debt rating.
 
    SP-1 Strong capacity to pay principal and interest. Those issues determined
         to possess overwhelming safety characteristics will be given a plus (+)
         designation.
 
    SP-2 Satisfactory capacity to pay principal and interest.
 
    SP-3 Speculative capacity to pay principal and interest.
 
DESCRIPTION OF PREFERRED STOCK RATINGS
 
MOODY'S
 
     aaa Top-quality preferred stock. This rating indicates good asset
         protection and the
<PAGE>   54
 
52
 
         least risk of dividend impairment within the universe of preferred
         stocks.
 
      aa High-grade preferred stock. This rating indicates that there is a
         reasonable assurance the earnings and asset protection will remain
         relatively well maintained in the foreseeable future.
 
       a Upper-medium grade preferred stock. While risks are judged to be
         somewhat greater than in the "aaa" and "aa" classification, earnings
         and asset protection are, nevertheless, expected to be maintained at
         adequate levels.
 
     baa Medium-grade preferred stock, neither highly protected nor poorly
         secured. Earnings and asset protection appear adequate at present but
         may be questionable over any great length of time.
 
S&P
 
S&P's preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations.
 
    AAA Highest rating. This rating indicates an extremely strong capacity to
        pay the preferred stock obligations.
 
     AA High-quality, fixed-income security. The capacity to pay preferred stock
        obligations is very strong, although not as overwhelming as for issues
        rated "AAA."
 
       A Backed by a sound capacity to pay the preferred stock obligations,
         although it is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions.
 
    BBB Backed by an adequate capacity to pay the preferred stock obligations.
        Whereas the issuer normally exhibits adequate protection parameters,
        adverse economic conditions or changing circumstances are more likely to
        lead to a weakened capacity to make payments for a preferred stock in
        this category than for issues in the "A" category.
 
SHORT-TERM DEBT RATINGS
 
Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.
 
  TBW-1 Very high degree of likelihood that principal and interest will be paid
        on a timely basis.
 
  TBW-2 While degree of safety regarding timely repayment of principal and
        interest is strong, the relative degree is not as high as for issues
        rated TBW-1.
 
  TBW-3 Lowest investment grade category. While more susceptible to adverse
        developments than obligations with higher ratings, capacity to service
        principal and interest in a timely fashion is considered adequate.
 
  TBW-4 Non-investment grade and, therefore, speculative.

                          A BRIEF PREVIEW OF THE FUNDS
 
             WHAT ARE THE GOALS OF THE MUNICIPAL BOND FUNDS?

             The Funds are designed to produce income exempt from Federal
             and/ or state income tax. Each Fund pursues a different
             investment objective and involves different risks. These Funds
             may not be appropriate for Individual Retirement Accounts,
             Qualified Plans, and other Retirement Plans that receive
             favorable tax treatment. Please read about each Fund before
             investing.
 
             WHAT ARE THE FUNDS' INVESTMENT STRATEGIES?
             The Intermediate Tax-Free Bond Fund and the Municipal Income
             Fund invest in debt securities issued by or on behalf of
             states, territories, and possessions of the United States and
             their agencies that produce interest that is exempt from
             Federal income tax. The Arizona Municipal Bond Fund, the West
             Virginia Municipal Bond Fund, the Louisiana Municipal Bond
             Fund, the Kentucky Municipal Bond Fund and the Ohio Municipal
             Bond Fund invest in debt securities of their respective states
             that produce interest that is exempt from Federal Income Tax
             and the personal income tax of each Fund's respective state.
 
             WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUNDS?
             The Funds invest in fixed-income investments that are subject
             to market fluctuations as a result of changes in interest
             rates. As a result, the value of investments in the Funds may
             decrease during periods of rising interest rates and increase
             during periods of declining interest rates. In addition, some
             of the Funds invest in mortgage-related securities which may
             have greater price and yield volatility than traditional
             fixed-income securities. All of the Funds, except the
             Intermediate Tax Free Bond Fund and the Municipal Income Fund,
             are non-diversified funds which expose investors to special
             risks, including risks associated with state specific
             investments. For more information about risks, please read
             "More About the Funds" and "Investment Risks."
 
             WHAT CLASSES OF SHARES ARE AVAILABLE?
             The Funds currently offer four classes of Shares: Class A,
             Class B, Class C and Fiduciary Class. Class A, Class B and
             Class C shares are offered to the general public. Fiduciary
             Class shares are offered to institutional investors, including
             affiliates of BANC ONE CORPORATION and any bank, depository
             institution, insurance company, pension plan or other
             organization authorized to act in fiduciary, advisory, agency,
             custodial or similar capacities. The section called "How To Do
             Business With The One Group" will provide more information.
 
             HOW DO I PURCHASE AND REDEEM SHARES?
   
             You may buy and redeem shares of the Funds on any day that the
             Funds are open for business. Class C shares are not available
             for purchase in all of the funds. Purchase and redemption
             procedures are explained in greater detail in "How To Do
             Business With The One Group." For additional information, call
             The One Group Services Company at 1-800-480-4111.
    
 
             HOW ARE DIVIDENDS PAID?
             Generally, dividends are declared on each business day and are
             distributed periodically on the first business day of each
             month. Any capital gains are distributed at least annually.
             Distributions are paid in additional shares of the same class
             unless you elect to take the payment in cash. For a more
             detailed discussion of dividends, see "Dividend Policies."
 
             WHO MANAGES THE FUNDS?
             Banc One Investment Advisors Corporation ("Banc One Investment
             Advisors"), an indirect subsidiary of BANC ONE CORPORATION,
             serves as the advisor of the Funds. Banc One Investment
             Advisors is paid a fee for its services. A more detailed
             discussion regarding Banc One Investment Advisors, its
             services and compensation can be found in the Prospectus under

THE ONE GROUP(R)
INTERMEDIATE TAX-FREE BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a diversified fund that seeks current income exempt from Federal
income taxes consistent with prudent investment management and the preservation
of capital.
 
[ICON] INVESTMENT STRATEGY
   
The Fund invests in bonds and notes of states, territories and possessions of
the United States, including the District of Columbia, and their respective
authorities, political subdivisions, agencies and instrumentalities, the
interest on which is exempt from Federal income tax ("Municipal Securities").
The Fund's average weighted maturity normally will range between three and ten
years.
    
 
[ICON] PORTFOLIO SECURITIES
   
The Fund invests at least 80% of its net assets in Municipal Securities. As a
matter of fundamental policy, the Fund invests at least 65% of its total assets
in bonds. The Fund also may invest in mortgage-backed securities, restricted
securities, and mortgage dollar rolls. The securities in which the Fund invests
may have fixed rates of return or floating or variable rates. For a list of all
securities in which the Fund may invest, please read "Investment Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund may invest in Municipal Securities that are rated in the lowest
investment grade. Even though such securities are generally considered
investment grade they are considered to have speculative characteristics.
Issuers of such securities are more vulnerable to changes in economic conditions
than issuers of higher grade securities. The Municipal Securities are also fixed
income investments. The value of these securities will change in response to
interest rate changes and other factors. In addition, the Fund invests in
mortgage-related securities which have significantly greater price and yield
volatility than traditional fixed-income securities. Before you invest, please
read "More About the Funds" and "Investment Risks."
 
[ICON] TAX CONSIDERATIONS
Up to 20% of the Fund's assets may be invested in Municipal Securities, the
interest on which is subject to the Federal alternative minimum tax.
Shareholders who are subject to the Federal alternative minimum tax may have all
or a portion of their income from the Fund subject to Federal income tax. In
addition, corporate shareholders will be required to take the interest on
Municipal Securities into account in determining their alternative minimum
taxable income.
 
[ICON] FUND MANAGEMENT
   
Patrick M. Morrissey has served as the manager of the Fund since February, 1994.
Since 1993, Mr. Morrissey also has managed the Municipal Income Fund. Mr.
Morrissey has been employed by Banc One Investment Advisors and its affiliates
since October, 1992. From September, 1986 to October, 1992, Mr. Morrissey served
as Portfolio Manager at Norwest Investments and Trust.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .60% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.21% for Class A shares, 1.86% for Class B
    shares, 1.86% for Class C shares and .86% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

Class B shares automatically convert to Class A shares after eight (8) years.
Therefore, the "10 years" examples above reflect this conversion.

THE ONE GROUP(R)
MUNICIPAL INCOME FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a diversified fund that seeks current income exempt from Federal
income taxes.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in debt securities of states, territories and possessions of
the United States, including the District of Columbia, and their respective
authorities, political subdivisions, agencies and instrumentalities, the
interest on which is exempt from Federal income tax ("Municipal Securities").
The Fund's average weighted maturity normally will range from five to fifteen
years, although the Fund may shorten its average weighted maturity to as little
as two years if appropriate for temporary defensive purposes.
 
[ICON] PORTFOLIO SECURITIES
   
The Fund invests at least 80% of its net assets in Municipal Securities. As a
matter of fundamental policy, the Fund invests at least 65% of its total assets
in bonds. As a matter of fundamental policy, the Fund will not invest more than
25% of its net assets (i) in securities within a single industry; or (ii) in
securities of governmental units or issuers in the same state, territory, or
possession. However, the Fund will, from time to time, invest more than 25% of
its net assets in municipal housing authority obligations and single-family
mortgage revenue bonds. The Fund also may invest in mortgage-backed securities,
restricted securities, and mortgage dollar rolls. The securities in which the
Fund invests may have fixed rates of return or floating or variable rates. For a
list of all securities in which the Fund may invest, please read "Investment
Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund may invest in Municipal Securities that are rated in the lowest
investment grade. Even though such securities are generally considered
investment grade securities, they are considered to have speculative
characteristics. Issuers of such securities are more vulnerable to changes in
economic conditions than issuers of higher grade securities. The Municipal
Securities are also fixed-income investments. The value of these securities will
change in response to interest rates and other factors. In addition, the Fund
invests in mortgage-related securities which may have greater price and yield
volatility than traditional fixed-income securities. Before you invest, please
read "More About the Funds" and "Investment Risks."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .45% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.07% for Class A shares, 1.72% for Class B
    shares, 1.72% for Class C shares and .72% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
ARIZONA MUNICIPAL BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a non-diversified fund that seeks current income exempt from Federal
income tax and Arizona personal income tax, consistent with the preservation of
principal.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in debt securities issued by or on behalf of Arizona and its
respective authorities, political subdivisions, agencies and instrumentalities,
the interest on which, in the opinion of issuer's counsel, is exempt from
Federal income tax and Arizona personal income tax ("Arizona Municipal
Securities"). The Fund's average weighted maturity normally will be between five
and twenty years, although the Fund may invest in securities of any maturity.
 
[ICON] PORTFOLIO SECURITIES
The Fund invests at least 80% of its total assets in Arizona Municipal
Securities. This is a fundamental policy. The Fund also may invest up to 20% of
its total assets in bonds and notes of states (other than Arizona) as well as of
territories and possessions of the United States, including the District of
Columbia, and their respective authorities, agencies, instrumentalities, and
political subdivisions, the interest on which is exempt from Federal income tax
("Municipal Securities"). The securities in which the Fund invests may have
fixed rates of return or floating or variable rates. For a list of all
securities in which the Fund may invest, please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in Arizona Municipal Securities, which may be impacted by
economic and political developments in Arizona. The Arizona Municipal Securities
also include fixed-income investments. The value of these securities will change
in response to interest rate changes and other factors. Before you invest,
please read "More About the Funds" and "Investment Risks."
 
[ICON] TAX CONSIDERATIONS
Up to 100% of the Fund's assets may be invested in Arizona Municipal Securities
and Municipal Securities the interest on which is subject to Federal alternative
minimum tax. Shareholders who are subject to the Federal alternative minimum tax
may have all or a portion of their income from the Fund subject to Federal
income tax. In addition, corporate shareholders will be required to take the
interest on Municipal Securities and Arizona Municipal Securities into account
in determining their alternative minimum taxable income.
 
[ICON] FUND MANAGEMENT
Todd Curtis, CFA, has served as the manager of the Fund since its inception in
1997. From 1984 to 1996, Mr. Curtis managed a bank common trust fund with
substantially the same investment objectives as the Fund. Mr. Curtis has been
involved in the management of both Arizona and national municipal securities
since 1984 and has been employed by Banc One Investment Advisors and its
affiliates in the investment management business since 1981.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .45% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.12% for Class A shares, 1.77% for Class B
    shares, 1.77% for Class C shares and .77% for Fiduciary Class shares.
 


 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
WEST VIRGINIA MUNICIPAL BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a non-diversified fund that seeks current income exempt from Federal
income tax and West Virginia personal income tax, consistent with the
preservation of principal.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in debt securities issued by or on behalf of West Virginia and
its respective authorities, political subdivisions, agencies and
instrumentalities, the interest on which, in the opinion of issuer's counsel, is
exempt from Federal income tax and West Virginia personal income tax ("West
Virginia Municipal Securities"). Generally, the Fund's average weighted maturity
will be between five and twenty years, although the Fund may invest in
securities of any maturity.

[ICON] PORTFOLIO SECURITIES
The Fund invests at least 80% of its total assets in West Virginia Municipal
Securities. This is a fundamental policy. The Fund also may invest up to 20% of
its total assets in bonds and notes of states (other than West Virginia) as well
as of territories and possessions of the United States, including the District
of Columbia, and their respective authorities, agencies, instrumentalities, and
political subdivisions, the interest on which is exempt from Federal income tax
("Municipal Securities"). The securities in which the Fund invests may have
fixed rates of return or floating or variable rates. For a list of all
securities in which the Fund may invest, please read "Investment Practices."

[ICON] RISK CONSIDERATIONS
The Fund invests in West Virginia Municipal Securities, which may be impacted by
economic and political developments in West Virginia. The West Virginia
Municipal Securities also include fixed-income investments. The value of these
securities will change in response to interest rate changes and other factors.
Before you invest, please read "More About the Funds" and "Investment Risks."
 
[ICON] TAX CONSIDERATIONS
Up to 100% of the Fund's assets may be invested in West Virginia Municipal
Securities and Municipal Securities the interest on which is subject to Federal
alternative minimum tax. Shareholders who are subject to the Federal alternative
minimum tax may have all or a portion of their income from the Fund subject to
Federal income tax. In addition, corporate shareholders will be required to take
the interest on Municipal Securities and West Virginia Municipal Securities into
account in determining their alternative minimum taxable income.

[ICON] FUND MANAGEMENT
   
David M. Sivinski, CFA, has served as the manager of the Fund since 1997. Prior
to that time, Mr. Sivinski managed a bank common trust fund with substantially

Louisiana Municipal Bond Fund since 1996. Mr. Sivinski has been with Banc One

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .45% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.12% for Class A shares, 1.77% for Class B
    shares, 1.77% for Class C shares and .77% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
LOUISIANA MUNICIPAL BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a non-diversified fund that seeks current income both consistent
with the preservation of principal and exempt from Federal income tax and
Louisiana income tax.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in investment grade municipal securities issued by or on behalf
of Louisiana and its authorities, political subdivisions, agencies and
instrumentalities, the interest on which, in the opinion of issuer's counsel, is
exempt from both Federal income tax and Louisiana state income tax ("Louisiana
Municipal Securities"). The Fund's average weighted maturity normally will be
between five and twenty years, although the Fund may invest in securities of any
maturity.
 
[ICON] PORTFOLIO SECURITIES
The Fund invests at least 80% of its net assets in Louisiana Municipal
Securities. This is a fundamental policy. The Fund also may hold up to 20% of
its total assets in cash or invest in municipal securities of other states
("Municipal Securities"), short-term taxable investments including repurchase
agreements, and U.S. Government Securities or other cash equivalents. The
securities in which the Fund invests may have fixed rates of return or floating
or variable rates. For a list of all securities in which the Fund may invest,
please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in Louisiana Municipal Securities, which may be impacted by
economic and political developments in Louisiana. The Louisiana Municipal
Securities also include fixed-income investments. The value of these securities
will change in response to interest rate changes and other factors. Before you
invest, please read "More About the Funds" and "Investment Risks."
 
[ICON] TAX CONSIDERATIONS
Up to 100% of the Fund's assets may be invested in Louisiana Municipal
Securities and Municipal Securities the interest on which is subject to Federal
alternative minimum tax. Shareholders who are subject to the Federal alternative
minimum tax may have all or a portion of their income from the Fund subject to
Federal income tax. In addition, corporate shareholders will be required to take
the interest on Municipal Securities and Louisiana Municipal Securities into
account in determining their alternative minimum taxable income.
 
[ICON] FUND MANAGEMENT
   
David M. Sivinski, CFA, has served as the manager of the Fund since February,
1996. Since 1994, Mr. Sivinski has also managed the Ohio and Kentucky Municipal
Bond Funds. Mr. Sivinski began managing the West Virginia Municipal Bond Fund in

(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .60% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.27% for Class A shares, 1.92% for Class B
    shares, 1.92% for Class C shares and .92% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
OHIO MUNICIPAL BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a non-diversified fund that seeks current income exempt from Federal
income tax and Ohio personal income tax, consistent with the preservation of
principal.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in debt securities issued by or on behalf of Ohio and its
respective authorities, political subdivisions, agencies and instrumentalities,
the interest on which, in the opinion of issuer's counsel, is exempt from
Federal income tax and Ohio personal income tax ("Ohio Municipal Securities").
Generally, the Fund's average weighted maturity will be between five and twenty
years, although the Fund may invest in securities of any maturity.
 
[ICON] PORTFOLIO SECURITIES
The Fund invests at least 80% of its total assets in Ohio Municipal Securities.
This is a fundamental policy. The Fund also may invest up to 20% of its total
assets in bonds and notes of states (other than Ohio) as well as of territories
and possessions of the United States, including the District of Columbia, and
their respective authorities, agencies, instrumentalities, and political
subdivisions, the interest on which, in the opinion of issuer's counsel, is
exempt from Federal income tax ("Municipal Securities"). The securities in which
the Fund invests may have fixed rates of return or floating or variable rates.
For a list of all securities in which the Fund may invest, please read
"Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in Ohio Municipal Securities, which may be impacted by economic
and political developments in Ohio. The Ohio Municipal Securities also include
fixed-income investments. The value of these securities will change in response
to interest rate changes and other factors. Before you invest, please read "More
About the Funds" and "Investment Risks."
 
[ICON] TAX CONSIDERATIONS
Up to 100% of the Fund's assets may be invested in Ohio Municipal Securities and
Municipal Securities the interest on which is subject to Federal alternative
minimum tax. Shareholders who are subject to the Federal alternative minimum tax
may have all or a portion of their income from the Fund subject to Federal
income tax. In addition, corporate shareholders will be required to take the
interest on Municipal Securities and Ohio Municipal Securities into account in
determining their alternative minimum taxable income.
 
[ICON] FUND MANAGEMENT
   
David M. Sivinski, CFA, has served as the manager of the Fund since May, 1994.
Since 1994, Mr. Sivinski also has managed the Kentucky Municipal Bond Fund. Mr.
Sivinski began managing the Louisiana Municipal Bond Fund in 1996 and the West
Virginia Municipal Bond Fund in 1997. Mr. Sivinski has been with Banc One

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .60% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.27% for Class A shares, 1.92% for Class B
    shares, 1.92% for Class C shares and .92% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
KENTUCKY MUNICIPAL BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a non-diversified fund that seeks current income exempt from Federal
income tax and Kentucky personal income tax, consistent with the preservation of
principal.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in debt securities issued by or on behalf of Kentucky and its
respective authorities, political subdivisions, agencies and instrumentalities,
the interest on which, in the opinion of issuer's counsel, is exempt from
Kentucky personal income tax ("Kentucky Municipal Securities"), as well as debt
securities that, in the opinion of issuer's counsel, produce interest that is
exempt from Federal income tax ("Municipal Securities"). Generally, the Fund's
average weighted maturity will be between five and twenty years, although the
Fund may invest in securities of any maturity.
 
[ICON] PORTFOLIO SECURITIES
The Fund invests at least 80% of its total assets in Municipal Securities.
Alternatively, the Fund invests its assets so that at least 80% of its annual
interest income is exempt from Federal income tax. The Fund invests at least 65%
of its total assets in Kentucky Municipal Securities. Each of these investment
policies are fundamental. The Fund may also invest up to 35% of its total assets
in bonds and notes of states (other than Kentucky) as well as of territories and
possessions of the United States, including the District of Columbia, and their
respective authorities, agencies, instrumentalities, and political subdivisions,
the interest on which is exempt from Federal income tax. The securities in which
the Fund invests may have fixed rates of return or floating or variable rates.
For a list of all securities in which the Fund may invest, please read
"Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in Kentucky Municipal Securities, which may be impacted by
economic and political developments in Kentucky. The Fund's investments also
include fixed-income investments. The value of these securities will change in
response to interest rate changes and other factors. Before you invest, please
read "More About the Funds" and "Investment Risks."
 
[ICON] TAX CONSIDERATIONS
Up to 100% of the Fund's assets may be invested in Kentucky Municipal Securities
and Municipal Securities the interest on which is subject to Federal alternative
minimum tax. Shareholders who are subject to the Federal alternative minimum tax
may have all or a portion of their income from the Fund subject to Federal
income tax. In addition, corporate shareholders will be required to take the
interest on Municipal Securities and Kentucky Municipal Securities into account
in determining their alternative minimum taxable income.
 
[ICON] FUND MANAGEMENT
   
David M. Sivinski, CFA, has served as the manager of the Fund since December,
1994. Mr. Sivinski also has managed the Ohio Municipal Bond Fund since 1994. Mr.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense Information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .45% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.12% for Class A shares, 1.77% for Class B
    shares, 1.77% for Class C shares and .77% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

                              MORE ABOUT THE FUNDS
 
                                                                              23
 
WHEN THE PROSPECTUS REFERS TO "BONDS", WHAT TYPES OF INVESTMENTS ARE INCLUDED?

"Bonds" include debt instruments issued by the U.S. Treasury, U.S. Government
agencies, mortgage related securities, municipalities and zero coupon
obligations as well as debt instruments issued by states and their respective
authorities, political subdivisions, agencies and instrumentalities.
 
PORTFOLIO QUALITY
- ----------------------------------------------------
 
The Funds only purchase securities that meet certain rating criteria:
 
- - Municipal Securities that are bonds must be rated as investment grade.
 
- - Arizona Municipal Securities, West Virginia Municipal Securities, Louisiana
  Municipal Securities, Ohio Municipal Securities, and Kentucky Municipal
  Securities that are bonds must be rated as investment grade.
 
- - Other securities such as tax-exempt commercial paper, notes, and variable
  demand obligations must be rated in one of the two highest investment grade
  categories.
 
- - The Louisiana Municipal Bond Fund may also invest in short-term tax-exempt
  municipal securities rated at least MIG3 (VMIG3) by Moody's or SP-2 by S&P.
  These securities may have speculative characteristics.
 
If the securities are unrated, Banc One Investment Advisors must determine that
they are of comparable quality to rated securities. Banc One Investment Advisors
will look at a security's rating at the time of investment. For more information
about ratings, please see "Description of Ratings" in the Appendix.
 
ILLIQUID INVESTMENTS
- ----------------------------------------------------
 
Each Fund may invest up to 15% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by The One Group Board of Trustees in determining whether an
investment is illiquid.
 
SPECIAL RISK
CONSIDERATIONS
- ----------------------------------------------------
 
   
FIXED INCOME SECURITIES: Investments in fixed income securities (for example,
bonds) will increase or decrease in value based on changes in interest rates. If
rates increase, the value of a Fund's investments generally declines. On the
other hand, if rates fall, the value of the investments generally increases. The
value of your investment in a Fund will increase and decrease as the value of a
Fund's investments increase and decrease. While securities with longer duration
and maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually, changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment.
    
 
DERIVATIVES: Some of the Funds invest in securities that are considered to be
derivatives. These securities may be more volatile than other investments. These
include:
 
- - options
 
- - futures contracts
 
- - options on futures contracts
 
- - mortgage-backed securities, including collateralized mortgage obligations and
  Real Estate Mortgage Investment Conduits (CMOs and REMICs) and stripped
  mortgage-backed securities (IOs and POs)
 
- - structured instruments
 
- - swaps, caps and floors
 
- - new financial products
 
- - inverse floating rate instruments
 
Derivatives may be riskier than traditional investments.
 
NON-DIVERSIFIED FUNDS: All of the Funds (except the Intermediate Tax-Free Bond
Fund and the Municipal Income Fund) are "non-diversified" funds. This means that
the Funds may invest a more significant portion of their assets in the
securities of a single issuer than can a "diversified" fund. In addition, the
Funds' investments are concentrated geographically. These concentrations
increase the risk of loss to the Funds if an issuer fails to make interest or
principal payments or if the market value of a security declines.
 
   
MUNICIPAL SECURITIES: Because the Arizona Municipal Bond Fund, the West Virginia
Municipal Bond Fund, the Louisiana Municipal Bond Fund, the Ohio Municipal Bond
Fund, and the Kentucky Municipal Bond Fund are not diversified and because they
concentrate in securities of Arizona, West Virginia, Louisiana, Ohio and
Kentucky issuers, respectively, certain factors may have a disproportionate
negative effect on the Funds' investments. These factors may include certain
economic conditions, constitutional amendments, legislative measures, executive
orders, administrative regulations and voter initiatives. For instance, the Ohio
economy relies to a significant degree on manufacturing. As a result, economic
activity in Ohio tends to be cyclical, which may affect the market value of Ohio
Municipal Securities or the ability of issuers to make timely payments of
interest and principal. Similarly, coal mining and related industries are an
important part of the West Virginia economy. Increased government regulation

and a reduced demand for coal has adversely affected that industry. The
Louisiana economy, like that of West Virginia, is heavily dependent on a single
industry, in this case energy (oil and gas). Louisiana continues to recover from
the oil price declines of the mid-1980's, although its debt burden is well above
that of other states, while wealth and income indicators are below the national
average. Both West Virginia and Louisiana post unemployment rates above the
national average.

Arizona's population growth continues to outpace the national average. However,
this growth is expensive and Arizona's economic outlook depends on its ability
to match long-term revenues with expenditures. In addition, Arizona's continued
growth depends to some extent on its ability to manage its water resources.

Unlike the municipal securities of most states, nearly all Kentucky Municipal
Securities are not general obligations of the issuer; rather, payment depends on
revenues generated by the property financed by the security.

securities, please see the Statement of Additional Information.
 
PURCHASING
FUND SHARES
- ----------------------------------------------------
 
WHERE CAN I BUY SHARES?
 
You may purchase Fund shares from the following sources:
 
- - The One Group Services Company, and
 
- - Shareholder Servicing Agents. These include investment advisors, brokers,
  financial planners, banks, insurance companies, retirement or 401(k) plan
  sponsors, or other intermediaries. Shares purchased this way will be held for
  you by the Shareholder Servicing Agent.
 
WHEN CAN I BUY SHARES?
 
- - Purchases may be made on any business day. This includes any day that the
  Funds are open for business, other than weekends and the following holidays:
  New Years Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
  Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas.
 
- - Purchase requests received by The One Group Services Company before 4 p.m.
  EST, will be effective that day.
 
- - Purchase orders may be cancelled by the Fund's Custodian, State Street Bank
  and Trust Company, if it does not receive "federal funds" by 4:00 p.m. EST (i)
  on the business day after the order is placed if you are buying Fiduciary
  Class shares, and (ii) on the third business day if you are purchasing Class
  A, Class B or Class C shares.
 
- - If your shares are held by a Shareholder Servicing Agent, it is the
  responsibility of the Shareholder Servicing Agent to send your purchase or
  redemption order to the Fund. Your Shareholder Servicing Agent may have an
  earlier cut-off time for purchase and redemption requests.
 
- - The One Group Services Company can reject a purchase order if it does not
  think that it is in the best interests of a Fund and/or its shareholders to
  accept the order.
 
- - Shares are electronically recorded. Therefore, certificates will not be
  issued.
 
WHAT KIND OF SHARES CAN I BUY?
 
The One Group offers the following classes of shares:
 
- - Class A, Class B and Class C shares are available to the general public.
 
- - Fiduciary Class shares are available to institutional investors and any
  organization authorized to act in a fiduciary, advisory, custodial or agency
  capacity. We will refer to these entities as "Intermediaries."
 
- - If you intend to hold your shares six or more years, Class B shares may be
  appropriate for you. If you intend to hold your shares for less than six
  years, you may want to consider Class A or Class C shares.
 
HOW MUCH DO SHARES COST?
 
- - Shares are sold at net asset value ("NAV") plus a sales charge, if any.
 
- - Each class of shares in each Fund has a different NAV. This is primarily
  because each class has different distribution expenses.
 
- - NAV per share is calculated by dividing the total market value of a Fund's
  investments and other assets allocable to a class (minus class expenses) by
  the number of outstanding shares in that class.
 
- - A Fund's NAV changes every day. NAV is calculated each business day at 4:00
  p.m. EST.
 
HOW DO I OPEN AN ACCOUNT?
 
1. Read the prospectus carefully, and select the Fund or Funds most appropriate
   for you.
 
2. Decide how much you want to invest.
 
   - The minimum initial investment is $1,000 ($100 for employees of BANC ONE
     CORPORATION and its affiliates).
 
   - Subsequent investments must be at least $100 ($25 for employees of BANC ONE
     CORPORATION and its affiliates).
 
   - You may purchase no more than $250,000 of Class B shares at one time.

   - The One Group Services Company may waive these minimums.

   by wire or bank transfer) payable to "The One Group" to:
 
   State Street Bank and Trust Company
   c/o The One Group

   accepted. Redemptions from a Fund will not be permitted for ten (10) calendar
   days if purchases are made by check or under the Systematic Investment Plan
   (see below).

   required to complete additional forms or follow additional procedures. You
   should contact your Shareholder Servicing Agent regarding purchases,
   exchanges and redemptions.

  1-800-480-4111 to relay your purchase instructions.
 
- - Send a personal check made payable to "The One Group" to State Street Bank and
  Trust Company (see address above), authorize a bank transfer or initiate a
  wire transfer.
 
- - The One Group uses reasonable procedures to confirm that instructions given by
  telephone are genuine. These procedures include recording telephone
  instructions and asking for personal identification. If these procedures are
  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
   
- - You may revoke your right to make purchases over the telephone by sending a
  letter to:
    
 
  State Street Bank and Trust Company
  c/o The One Group
  P.O. Box 8500

CAN I AUTOMATICALLY INVEST ON A
SYSTEMATIC BASIS?
 
Yes. After your Account is established, you may purchase additional Class A,
Class B and Class C shares by making automatic monthly investments from your
bank account. The minimum initial investment is still $1,000, but minimum

minimums. To establish a Systematic Investment Plan:

  to:
    
 
  State Street Bank and Trust Company
  c/o The One Group

CONVERSION FEATURE
 
Your Class B shares automatically convert to Class A shares after eight years
(measured from the end of the month in which they were purchased).
 
- - After conversion, your shares will be subject to the lower distribution and
  shareholder servicing fees charged on Class A shares
 
- - You will not be assessed any sales charges or fees for conversion of shares,
  nor will you be subject to any tax.
 
- - Because the share price of the Class A shares may be higher than that of the
  Class B shares at the time of conversion, you may receive fewer Class A
  shares; however, the dollar value will be the same.
 
- - If you have exchanged Class B shares of one Fund for Class B shares of
  another, the time you held the shares in each Fund will be added together.
 
SALES CHARGES
- ----------------------------------------------------
 
   
The One Group Services Company compensates Shareholder Servicing Agents who sell
shares of The One Group. Compensation comes from: sales charges, 12b-1 fees and
payments by The One Group Services Company from its own resources. The One Group
Services Company, at its own expense, also will provide promotional incentives
in the form of travel expenses, lodging and bonuses to licensed individuals who
sell shares of the Funds, as well as vacation trips (including lodging at luxury
resorts), tickets to entertainment events, and merchandise.

   sales charge at the time of purchase, you will be charged the equivalent of

   within one year of purchase.
 
 CLASS B SHARES
 
Class B shares are offered at NAV, without any up-front sales charges. However,
if you redeem these shares within six years of the purchase date, you will be
assessed a Contingent Deferred Sales Charge ("CDSC") according to the following
 
<TABLE>
<CAPTION>
schedule:

</TABLE>
 
The One Group Services Company pays a commission of 4.00% of the original
purchase price to Shareholder Servicing Agents who sell Class B shares.
 
 CLASS C SHARES
 
Class C shares are offered at NAV, without any up-front sales charge. However,
if you redeem your shares within one year of the purchase date, you will be
 
<TABLE>
<CAPTION>
assessed a CDSC as follows:
                          CDSC AS A % OF DOLLAR
YEARS SINCE PURCHASE     AMOUNT SUBJECT TO CHARGE
<S>                      <C>                      
         0-1                  1.00%
  After first year            None
</TABLE>
 
Shareholder Servicing Agents selling Class C shares receive a commission of
1.00% of the original purchase price from The One Group Services Company.
 
How the CDSC is Calculated
 
- - The Fund assumes that all purchases made in a given month were made on the
  first day of the month.
 
- - The CDSC is based on the current market value or the original cost of the
  shares, whichever is less.
 
- - A sales charge is not imposed on increases in NAV above the initial purchase
  price, nor is a sales charge assessed on shares acquired through reinvestment
  of dividends or capital gains distributions.
 
- - To keep your CDSC as low as possible, the Fund first will redeem any shares in
  your account that carry no CDSC, starting with Class A shares. After that, the
  Fund will redeem the shares you have held for the longest time and thus have
  the lowest CDSC.

                                                                              27
 
12B-1 FEES
 
12b-1 fees are paid by The One Group to The One Group Services Company as
compensation for its services and expenses. The One Group Services Company in
turn pays all or part of the 12b-1 fee to Shareholder Servicing Agents that sell
shares of The One Group.
 
- - The 12b-1 fees vary by share class as follows:
 
   1. Class A shares pay a 12b-1 fee of .35% of the average daily net assets of
      the Fund, which is currently being waived to .25%.
 
   2. Class B and Class C shares pay a 12b-1 fee of 1.00% of the average daily
      net assets of the Fund, which is currently being waived to .90%. This will
      cause expenses for Class B and Class C shares to be higher and dividends
      to be lower than for Class A shares.
 
   3. There are no 12b-1 fees for Fiduciary Class shares.
 
- - 12b-1 fees, together with the CDSC, help The One Group Services Company sell
  Class B and Class C shares without an "up-front" sales charge by defraying the
  costs of advancing brokerage commissions and other expenses paid to
  Shareholder Servicing Agents.
 
- - The One Group Services Company may use up to .25% of the fees for shareholder
  servicing and up to .75% for distribution. During the last fiscal year, The
  One Group Services Company received 12b-1 fees totaling .25% and 1.00% of the
  average daily net assets of Class A and Class B shares, respectively.
 
- - The One Group Services Company may pay 12b-1 fees to its affiliates and to
  Banc One Investment Advisors and its affiliates (or any sub-advisor) for
  brokerage and other agency transactions.
 
SALES CHARGE
REDUCTIONS
AND WAIVERS
- ----------------------------------------------------
 
REDUCING YOUR CLASS A SALES CHARGES
 
There are several ways you can reduce the sales charges you pay on Class A
shares:
 
1. Right of Accumulation: You may add the market value of any Class A, Class B
   or Class C shares of a Fund (except a money market fund) that you (and your
   spouse and minor children) already own of any One Group Fund (except a money
   market fund) to the amount of your next Class A purchase for purposes of
   calculating the sales charge. An Intermediary also may take advantage of this
   option.
 
2. Letter of Intent: With an initial investment of $2,000, you may purchase
   Class A shares of one or more Funds over the next 13 months and pay the same
   sales charge that you would have paid if all shares were purchased at once. A
   percentage of your investment will be held in escrow until the full amount
   covered by the Letter of Intent has been invested.
 
To take advantage of the accumulation privilege or letter of intent, complete
the appropriate section of your fund application, or contact your Shareholder
Servicing Agent. To determine if you are eligible for the accumulation
privilege, contact The One Group Services Company at 1-800-480-4111. These

                                                                              29
 
WHEN ARE EXCHANGES PROCESSED?
 
Exchanges are processed the same business day they are received, provided:
 
- - State Street Bank and Trust Company receives the request by 4:00 p.m. EST.
 
- - You have provided The One Group with all of the information necessary to
  process the exchange.
 
- - You have received a current prospectus of the Fund or Funds in which you wish
  to invest.
 
- - You have contacted your Shareholder Servicing Agent, if necessary.
 
DO I PAY A SALES CHARGE ON AN EXCHANGE?
 
Generally, you will not pay a sales charge on an exchange. However:
 
- - You will pay a sales charge if you own Fiduciary Class shares of a Fund and
  you want to exchange those shares for Class A shares, unless you qualify for a
  sales charge waiver (see above).
 
- - You will pay a sales charge if you bought Class A shares of a Fund:
 
   1. That does not charge a sales charge and you want to exchange them for
      shares of a Fund that does, in which case you would pay the sales charge
      applicable to the Fund into which you are exchanging.
 
   2. That charged a lower sales charge than the Fund into which you are
      exchanging, in which case you would pay the difference between that Fund's
      sales charge and all other sales charges you have already paid.
 
- - If you exchange Class B or Class C shares of a Fund, you will not pay a sales
  charge at the time of the exchange, however:
 
   1. Your new Class B or Class C shares will be subject to the higher CDSC of
      either the Fund from which you exchanged, the Fund into which you
      exchanged, or any Fund from which you previously exchanged.
 
   2. The current holding period for your exchanged Class B or Class C shares is
      carried over to your new shares.
 
ARE EXCHANGES TAXABLE?
 
Generally:
 
- - An exchange between classes of shares of the same Fund is not taxable.
 
- - An exchange between Funds is considered a sale and generally results in a
  capital gain or loss for Federal income tax purposes.
 
- - You should talk to your tax advisor before making an exchange.
 
ARE THERE LIMITS ON EXCHANGES?
 
Yes. The exchange privilege is not intended as a way for you to speculate on
short-term movements in the market. Therefore:
 
- - To prevent disruptions in the management of the Funds, The One Group limits
  excessive exchange activity.
 
- - Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
  REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH PERIOD.
 
   
- - In addition, The One Group reserves the right to reject any exchange request
  (even those that are not excessive) if the Fund reasonably believes that the
  exchange will result in excessive transaction costs or otherwise adversely
  affect other shareholders.

- - On the Account Application Form you may elect to have the redemption proceeds
  mailed or wired to:
 
   
   1. a designated commercial bank; or
    
 
   2. State Street Bank and Trust Company or your Shareholder Servicing Agent.
 
   
- - State Street Bank and Trust Company may charge you a wire redemption fee. The
  current charge is $7.00.
    
 
- - Your redemption proceeds will be paid within seven days after receipt of the
  redemption request.
 
WHAT WILL MY SHARES BE WORTH?
 
- - If you own Class A and Fiduciary Class shares and the Fund receives your
  redemption request by 4:00 p.m. EST, you will receive that day's NAV.
 
- - If you own Class B or Class C shares and the Fund receives your redemption
  request by 4:00 p.m. EST, you will receive that day's NAV, minus the amount of
  any applicable CDSC.
 
CAN I REDEEM BY TELEPHONE?
 
Yes, if you selected this option on your Account Application Form.
 
- - Call your Shareholder Servicing Agent or State Street Bank and Trust Company
  at 1-800-480-4111 to relay your redemption request.
 
- - Your redemption proceeds will be mailed or wired to the commercial bank

- - State Street Bank and Trust Company may charge you a wire redemption fee. The

  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
CAN I REDEEM ON A SYSTEMATIC BASIS?
 
If you have an account value of at least $10,000 you may elect to receive

- - You may designate a person other than yourself as the payee.
 
- - There is no charge for this service.
 
- - If you select this option, please keep in mind that:
 
   1. It may not be in your best interest to buy additional Class A shares while
      participating in a Systematic Withdrawal Plan. This is because Class A
      shares have an up-front sales charge.
 
   2. If you own Class B or Class C shares, you or your designated payee may
      receive systematic payments provided the payments are limited to no more
      than 10% of your account value annually, measured from the date the
      redemption request is received.
 
   3. If the amount of the systematic payment exceeds the income earned by your
      account since the previous payment under the Systematic Withdrawal Plan,
      payments will be made by redeeming some of your shares. This will reduce
      the amount of your investment.
 
ADDITIONAL INFORMATION REGARDING REDEMPTIONS
 
- - All redemptions will be for cash.
 
- - If you redeem shares for which you paid by check, and The One Group has not
  yet received payment on the check, The One Group will delay forwarding your
  redemption proceeds for 10 or more days until payment has been collected from
  your bank.
 
- - Because of the high cost of handling small investments, The One Group will
  automatically redeem shares in accounts which, because of shareholder
  redemptions, have values of less than $1,000. No sales charges will be
  assessed and you will be given 60 days to make additional investments in the
  Fund to increase the value of your account to at least $1,000.
 
- - The One Group may suspend your ability to redeem, or will redeem your shares
  involuntarily, when it seems appropriate to do so in light of its
  responsibilities under the Federal securities laws. The Statement of
  Additional Information offers more details about this process.

VOTING RIGHTS
- ----------------------------------------------------
 
The Funds do not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change a Fund's fundamental investment objective, or approve an
investment advisory contract.
 
As a Fund shareholder, you have one vote for each share that you own. Each Fund,
and each class of shares within each Fund, vote separately on matters relating
solely to that Fund or class, or which affect that Fund or class differently.
However, all shareholders will have equal voting rights on matters that affect
all shareholders equally.
BANC ONE CORPORATION (100 East Broad Street, Columbus, Ohio, 43271), through its
affiliates, may be deemed for purposes of the Investment Company Act of 1940 to
control the Funds. This is because as of August 5, 1997, BANC ONE CORPORATION or
its affiliates possessed the power to vote substantially all of the Fiduciary
Class shares of the Funds.
 
On that same date, the following shareholders owned 25% or more of Class A,
Class B and Class C shares of the Funds. As a consequence, they are considered
 
<TABLE>
<CAPTION>
to be controlling persons of these classes of the Funds.

DIVIDEND POLICIES
- ----------------------------------------------------
 
DIVIDENDS
 
The Funds generally declare dividends daily. Dividends are distributed on the
first business day of each month. Capital gains, if any, for all Funds are
distributed at least annually.
 
The Funds pay dividends and distributions on a per-share basis. This means that
the value of your shares will be reduced by the amount of the payment. If you
purchase shares shortly before the record date for a dividend or the
distribution of capital gains, you will pay the full price for the shares and
receive some portion of the price back as a taxable dividend or distribution.
 
Dividends payable on Fiduciary Class shares will be more than those payable on
other classes of shares. This is because Class A, Class B and Class C shares
have higher distribution expenses.
 
DIVIDEND REINVESTMENT
 
You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund and class, unless you have
elected to take such payment in cash. The price of the shares is the NAV
determined immediately following the dividend record date. Reinvested dividends
and distributions receive the same tax treatment as dividends and distributions
paid in cash.
 
If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8500, Boston, MA
02266-8500, at least 15 days prior to the distribution. The change is effective
upon receipt by State Street.
 
SPECIAL DIVIDEND RULES FOR CLASS B SHARES
 
Class B shares received as dividends and capital gains distributions will be
accounted for separately. Each time any Class B shares (other than those in the
sub-account) convert to Class A shares, a percentage of the Class B shares in
the sub-account will also convert to Class A shares. (See "Conversion Feature.")
<PAGE>   89

TAX TREATMENT
OF THE FUNDS
- ----------------------------------------------------
 
TAX STATUS OF THE FUND
 
Each Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Funds qualify, as they have in the past, they will
pay no federal income tax on the earnings they distribute to shareholders.
 
TAX TREATMENT
OF SHAREHOLDERS
- ----------------------------------------------------
 
TAXATION OF SHAREHOLDER TRANSACTIONS
 
A sale, exchange, or redemption of Fund shares generally will produce either a
taxable gain or a loss. You are responsible for any tax liabilities generated by
your transactions.
 
FEDERAL TAXATION OF DISTRIBUTIONS
 
EXEMPT-INTEREST DIVIDENDS. If, at the close of each quarter of its taxable year,
at least 50% of the value of a Fund's assets consists of obligations the
interest on which is excludable from gross income, the Fund may pay
"exempt-interest dividends" to you. Generally, exempt-interest dividends are
excludable from gross income. However:
 
1. If you receive Social Security or Railroad Retirement benefits, you may be
   taxed on a portion of such benefits if you receive exempt-interest dividends
   from the Funds.
 
2. Receipt of exempt-interest dividends may result in liability for Federal
   alternative minimum tax and for state and local taxes, both for individual
   and corporate shareholders.
 
INTEREST ON PRIVATE ACTIVITY BONDS: The Municipal Income Fund, the Arizona
Municipal Bond Fund, the West Virginia Municipal Bond Fund, the Kentucky
Municipal Bond Fund, the Louisiana Municipal Bond Fund and the Ohio Municipal
Bond Fund may invest as much as 100% of their assets in municipal securities
issued to finance private activities the interest on which is a tax preference
item for purposes of the Federal alternative minimum tax ("Private Activity
Bonds"). The Intermediate Tax-Free Bond Fund may invest as much as 20% of its
assets in such Private Activity Bonds. As a result, Fund shareholders who are
subject to the Federal alternative minimum tax may have all or a portion of
their income from those Funds subject to Federal income tax. Additionally,
corporate shareholders will be required to take the interest on municipal
securities (including municipal securities of each Fund's respective state) into
account in determining their alternative minimum taxable income. Persons who are
substantial users of facilities financed by private activity bonds or who are
"related persons" of such substantial users should consult their tax advisors
before investing in the Funds.
 
INVESTMENT INCOME AND CAPITAL GAINS DIVIDENDS. Each Fund will distribute
substantially all of its net investment income (including net short-term capital
gains) on at least an annual basis. Dividends you receive from a Fund, other
than "exempt-interest dividends," will be taxable to you, whether reinvested or
received in cash. Dividends from a Fund's net investment income, if any, will be
taxable as ordinary income and capital gains dividends will be taxable to you as
such, regardless of how long you have held the shares.
 
Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid the previous December.
 
STATE AND LOCAL TAXATION OF DISTRIBUTIONS: Dividends that are derived from the
Funds' investments in U.S. government obligations may not be entitled to the
exemptions from state and local taxes that would be available if you purchased
U.S. government obligations directly.
 
The funds will notify you annually of the percentage of income and distributions
derived from U.S. government obligations. Unless otherwise discussed below,
investment income and capital gains dividends may be subject to state and local
taxes.
 
LOUISIANA TAXES: Distributions from the Louisiana Municipal Bond Fund, which are
derived from interest on tax-exempt obligations of the State of Louisiana or its
political subdivisions and certain obligations of the United States or its
territories, are exempt from Louisiana income tax.
 
ARIZONA TAXES: Exempt-interest dividends from the Arizona Municipal Bond Fund,
which are derived from interest on tax-exempt obligations of the State of
Arizona and its political subdivisions are exempt from Arizona income tax. Other
distributions from the Fund, including those related to long-term and short-term
capital gains, will be subject to Arizona income tax. Arizona law does not
permit a deduction for interest paid or accrued on indebtedness incurred or
continued to purchase or carry obligations, the interest on which is exempt from
Arizona income tax.
 
WEST VIRGINIA TAXES: Distributions from the West Virginia Bond Fund, which are
derived from interest or dividends on obligations or a securities of a West
Virginia state or local governmental body, generally are exempt from West
Virginia income tax. In addition, you will not pay that tax on the portion of
your income from the Fund which represents interest or dividends received from
the
<PAGE>   90
 
                                                                              33
 
Fund on obligations or securities of the United States and some of its
authorities, commissions or instrumentalities.
 
KENTUCKY TAXES: Dividends received from the Kentucky Municipal Bond Fund which
are derived from interest on Kentucky Municipal Securities are exempt from the
Kentucky individual income tax. Dividends paid from interest earned on
securities that are merely guaranteed by the Federal government, repurchase
agreements collateralized by U.S. government obligations, or from interest
earned on obligations of other states are not exempt from Kentucky individual
income tax. Any distributions of net short-term and net long-term capital gain
earned by the Fund are includable in each Shareholder's Kentucky adjusted gross
income as dividend income and long-term capital gain, respectively, and are both
taxed at ordinary income tax rates.
 
OHIO TAXES: Dividends received from the Ohio Municipal Bond Fund which are
derived from interest on Ohio Municipal Securities are exempt from the Ohio
personal income tax. In addition, gain from the sale or transfer of certain Ohio
Municipal Securities is also exempt from Ohio income tax. Certain Ohio
municipalities may have retained the right to tax dividends from the Fund.
Corporate investors must include the Fund shares in the corporation's tax base
for purposes of the Ohio franchise tax net worth computation, but not for the
net income computation.
 
TAX INFORMATION
 
The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Funds provide you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Funds or their shareholders.

INVESTMENT RISKS
- ----------------------------------------------------
 
Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities held by the Funds may fluctuate, as will the value of
your investment in the Funds. Certain investments are more susceptible to these
risks than others.
 
- - CREDIT RISK. The risk that the issuer of a security, or the counterparty to a
  contract, will default or otherwise be unable to honor a financial obligation.
  Credit risk is generally higher for non-investment grade securities. The price
  of a security can be adversely affected prior to actual default as its credit
  status deteriorates and the probability of default rises.
 
   
- - LEVERAGE RISK. The risk associated with securities or practices that multiply
  small index or market movements into large changes in value. Leverage is often
  associated with investments in derivatives, but also may be embedded directly
  in the characteristics of other securities.
    
 
   - HEDGED. When a derivative (a security whose value is based on another
     security or index) is used as a hedge against an opposite position that the
     fund also holds, any loss generated by the derivative should be
     substantially offset by gains on the hedged investment, and vice versa.
     While hedging can reduce or eliminate losses, it can also reduce or
     eliminate gains. Hedges are sometimes subject to imperfect matching between
     the derivative and underlying security, and there can be no assurance that
     a Fund's hedging transactions will be effective.
 
   - SPECULATIVE. To the extent that a derivative is not used as a hedge, the
     fund is directly exposed to the risks of that derivative. Gains or losses
     from speculative positions in a derivative may be substantially greater
     than the derivative's original cost.
 
- - LIQUIDITY RISK. The risk that certain securities may be difficult or
  impossible to sell at the time and the price that normally prevails in the
  market. The seller may have to lower the price, sell other securities instead
  or forego an investment opportunity, any of which could have a negative effect
  on fund management or performance. This includes the risk of missing out on an
  investment opportunity because the assets necessary to take advantage of it
  are tied up in less advantageous investments.
 
- - MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
  to produce the intended result. This includes the risk that changes in the
  value of a hedging instrument will not match those of the asset being hedged.
  Incomplete matching can result in unanticipated risks.
 
- - MARKET RISK. The risk that the market value of a security may move up and
  down, sometimes rapidly and unpredictably. These fluctuations may cause a
  security to be worth less than the price originally paid for it, or less than
  it was worth at an earlier time. Market risk may affect a single issuer,
  industry, sector of the economy or the market as a whole. There is also the
  risk that the current interest rate may not accurately reflect existing market
  rates. For fixed income securities, market risk is largely, but not
  exclusively, influenced by changes in interest rates. A rise in interest rates
  typically causes a fall in values, while a fall in rates typically causes a
  rise in values. Finally, key information about a security or market may be
  inaccurate or unavailable. This is particularly relevant to investments in
  foreign securities.
 
- - POLITICAL RISK. The risk of losses attributable to unfavorable governmental or
  political actions, seizure of foreign deposits, changes in tax or trade
  statutes, and governmental collapse and war.
 
- - FOREIGN INVESTMENT RISK. Risk associated with higher transaction costs,
  delayed settlements, currency controls and adverse economic developments. This
  also includes the risk that fluctuations in the exchange rates between the
  U.S. dollar and foreign currencies may negatively affect an investment.
  Adverse changes in exchange rates may erode or reverse any gains produced by
  foreign currency denominated investments and may widen any losses. Exchange
  rate volatility also may affect the ability of an issuer to repay U.S. dollar
  denominated debt, thereby increasing credit risk.
 
- - PRE-PAYMENT RISK. The risk that the principal repayment of a security will
  occur at an unexpected time, especially that the repayment of a mortgage or
  asset-backed security occurs either significantly sooner or later than
  expected. Changes in pre-payment rates can result in greater price and yield
  volatility. Pre-payments generally accelerate when interest rates decline.
<PAGE>   95
 
38
 
  When mortgage and other obligations are pre-paid, a Fund may have to reinvest
  in securities with a lower yield. Further, with early prepayment, a Fund may
  fail to recover any premium paid, resulting in an unexpected capital loss.
 
- - TAX RISK. The risk that the issuer of the securities will fail to comply with
  certain requirements of the Internal Revenue Code, which would cause adverse
  tax consequences.
 
- - REGULATORY RISK. The risk associated with Federal and state laws which may
  restrict the remedies that a mortgage lender has when a borrower defaults on
  mortgage loans. These laws include restrictions on foreclosures, redemption
  rights after foreclosure, Federal and state bankruptcy and debtor relief laws,
  restrictions on "due on sale" clauses, and state usury laws.
 
INVESTMENT POLICIES
- ----------------------------------------------------
 
Each Fund's investment objective and the following investment policies
summarized below are fundamental. This means that they cannot be changed without
the consent of a majority of the outstanding shares of the Funds. In addition to
the fundamental policies mentioned earlier, the following fundamental policies
apply to each Fund as specified. The full text of the fundamental policies can
be found in the Statement of Additional Information.
 
INVESTMENT POLICIES FOR SPECIFIC FUNDS
 
The Intermediate Tax-Free Bond Fund and the Municipal Income Fund may not:
 
1. Purchase the securities of an issuer if as a result more than 5% of its total
   assets would be invested in the securities of that issuer, or the Fund would
   own more than 10% of the outstanding voting securities of that issuer. This
   does not include securities issued or guaranteed by the United States, its
   agencies or instrumentalities, and repurchase agreements involving these
   securities. This restriction applies to 75% of a Fund's total assets.
 
2. Concentrate in a particular industry or group of industries. This does not
   include Municipal Securities or governmental guarantees of Municipal
   Securities, and with respect to the Municipal Income Fund, housing authority
   obligations. Private activity bonds that are backed only by the assets and
   revenues of a non-governmental issuer are not Municipal Securities for
   purposes of this restriction.
 
The Arizona Municipal Bond Fund, the West Virginia Municipal Bond Fund, the
Louisiana Municipal Bond Fund, the Ohio Municipal Bond Fund and the Kentucky
Municipal Bond Fund may not:
 
1. Purchase the securities of an issuer if as a result more than 25% of its
   total assets would be invested in the securities of that issuer. This
   restriction applies with respect to 50% of a Fund's total assets. With
   respect to the remaining 50% of its total assets, a Fund may not purchase the
   securities of an issuer if as a result more than 5% of its total assets would
   be invested in the securities of that issuer. This restriction does not apply
   to securities issued or guaranteed by the United States, its agencies, or
   instrumentalities, securities of regulated investment companies, and
   repurchase agreement involving such securities.
 
2. Concentrate their investment in the securities of one or more issuers
   conducting their principal business in a particular industry or group of
   industries. This does not include:
 
   - Obligations issued or guaranteed by the U.S. government or its agencies and
     instrumentalities and repurchase agreements involving such securities;
 
   - Municipal Securities; and
 
   - Ohio Municipal Securities, Kentucky Municipal Securities, Arizona Municipal
     Securities, West Virginia Municipal Securities, and Louisiana Municipal
     Securities or governmental guarantees of such securities. With respect to
     the Arizona Municipal Bond Fund and the West Virginia Municipal Bond Fund,
     private activity bonds that are backed only by the assets and revenues of a
     non-governmental issuer are not Arizona Municipal Securities or West
     Virginia Municipal Securities for purposes of this restriction.
 
INVESTMENT POLICIES FOR ALL FUNDS
 
None of the Funds may make loans, except that a Fund may (i) purchase or hold
debt instruments in accordance with its investment objective and policies; (ii)
enter into repurchase agreements; and (iii) engage in securities lending.
 
Additional investment policies are set forth in the Statement of Additional
Information.
 
TEMPORARY DEFENSIVE POSITION
 
For temporary defensive purposes, each Fund may invest up to 100% of its assets
in money market instruments and may hold a portion of its assets in cash for
liquidity purposes.
<PAGE>   96
 
                                                                              39
 
The Arizona Municipal Bond Fund, the West Virginia Municipal Bond Fund, the
Louisiana Municipal Bond Fund and the Ohio Municipal Bond Fund also may invest
up to 20% of their total assets in securities other than Arizona, West Virginia,
Louisiana and Ohio Municipal Securities, respectively. The Kentucky Municipal
Bond Fund may invest up to 35% of its total assets in securities other than
Kentucky Municipal Securities.
 
While the Funds are engaged in a temporary defensive position, they will not be
pursuing their investment objectives. Therefore, the Funds will pursue a
temporary defensive position only when market conditions warrant.
 
PORTFOLIO TURNOVER
 
Portfolio turnover may vary greatly from year to year, as well as within a
particular year.
 
Higher portfolio turnover rates will likely result in higher transaction costs
to the Funds and may result in additional tax consequences to you. The portfolio
turnover rate for each Fund for the fiscal year ended June 30, 1997 is shown on
the Financial Highlights.

DESCRIPTION OF RATINGS
 
The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.
 
Unrated securities will be treated as non-investment grade securities unless
Banc One Investment Advisors determines that such securities are the equivalent
of investment grade securities. Securities that have received different ratings
from more than one agency are considered investment grade if at least one agency
has rated the security investment grade.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS

IBCA LIMITED ("IBCA")
 
      A1 Highest capacity for timely repayment. Those issues rated A1+ possess a
         particularly strong credit feature.

        obligation is very strong.
 
       A The obligation is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than obligations in
         higher rated categories. However, the obligor's capacity to meet its
         financial commitment on the obligation is still strong.
 
DESCRIPTION OF INSURANCE RATINGS
 
MOODY'S
 
These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.
 
    AAA Insurance companies rated in this category offer exceptional financial
        security. While the financial strength of these companies is likely to
        change, such changes as can be visualized are most unlikely to impair
        their fundamentally strong position.
 
      AA These insurance companies offer excellent financial security. Together
         with the Aaa group, they constitute what are generally known as high
         grade companies. They are rated lower than Aaa companies because
         long-term risks appear somewhat larger.
 
       A Insurance companies rated in this category offer good financial
         security. However, elements may be present which suggest a
         susceptibility to impairment sometime in the future.
 
S&P
 
S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.
 
    AAA This is the highest rating assigned by S&P. The obligor's capacity to
        meet its financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A An obligation rated A is somewhat more susceptible to the adverse
         effects of changes in circumstances and economic conditions than
         obligations in higher rated categories. However, the obligor's capacity
         to meet its financial commitment on the obligation is still strong.
 
DESCRIPTION OF MUNICIPAL BOND RATINGS
(including mortgage and asset-backed securities)
 
S&P
 
Investment Grade
 
    AAA The highest rating. The rating indicates an extremely strong capacity to
        meet its financial commitment.
 
     AA Differs from AAA issues only in a small degree. The obligor's capacity
        to meet its financial commitment is very strong.
 
       A These bonds are somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than debt in higher
         rated categories. However, capacity to meet its financial commitment on
         the obligations is still strong.
 
    BBB Exhibits adequate protection parameters. However, adverse economic
        conditions or changing circumstances are more likely to lead to a
        weakened capacity to meet its financial commitment on the obligations.
 
Speculative Grade
 
     BB Less vulnerable to non-payment than other speculative issues. However,
        these bonds face major ongoing uncertainties or exposure to adverse
        business, financial or economic conditions which could lead to
        inadequate capacity to meet financial commitment on the obligation.
 
       B More vulnerable to non-payment than obligations rated BB, but currently
         has the capacity to meet its financial commitment on the obligation.
         Adverse business, financial or economic conditions will likely impair
         capacity or willingness to meet its financial commitment on the
         obligation.
 
    CCC Currently vulnerable to non-payment, and is dependent upon favorable
        business, financial, and economic conditions to meet its financial
        commitment on the
<PAGE>   99
42
 
        obligation. In the event of adverse business, financial, or economic
        conditions, they are not likely to have the capacity to meet its
        financial commitment on the obligation.
 
      CC Currently highly vulnerable to non-payment.
 
       C This rating may be used to cover a situation where a bankruptcy
         petition has been filed, or similar action has been taken, but payments
         on this obligation are being continued.
 
       D Bonds in payment default.
 
Ratings from AA to CCC may be modified by a plus (+) or minus (-) to show
relative standing within the major rating categories.
 
MOODY'S
 
Investment Grade
 
    AAA Best quality. They carry the smallest degree of investment risk and are
        generally referred to as "gilt edged." Interest payments are protected
        by a large, or an exceptionally stable, margin and principal is secure.
 
      AA High quality by all standards. Margins of protection may not be as
         large as in Aaa securities, fluctuation of protective elements may be
         greater, or there may be other elements present that make the long-term
         risks appear somewhat larger than in Aaa securities.
 
       A These bonds possess many favorable investment attributes and are to be
         considered as upper-medium grade obligations. Factors giving security
         to principal and interest are considered adequate, but elements may be
         present which suggest a susceptibility to impairment sometime in the
         future.
 
    BAA These bonds are considered medium-grade obligations (i.e., they are
        neither highly protected nor poorly secured). Interest payments and
        principal security appear adequate for the present but certain
        protective elements may be lacking or may be characteristically
        unreliable over any great length of time. Such bonds lack outstanding
        investment characteristics and in fact have speculative characteristics
        as well.
 
Non-Investment Grade
 
      BA These bonds have speculative elements; their future cannot be
         considered as well assured. The protection of interest and principal
         payments may be very moderate and thereby not well safeguarded during
         good and bad times over the future.
 
       B These bonds lack the characteristics of a desirable investment (i.e.,
         potentially low assurance of timely interest and principal payments or
         maintenance of other contract terms over any long period of time may be
         small).
 
     CAA Bonds in this category have poor standing and may be in default. These
         bonds carry an element of danger with respect to principal and interest
         payments.
 
      CA Speculative to a high degree and could be in default or have other
         marked shortcomings. Ca is the lowest rating.
 
DESCRIPTION OF MUNICIPAL NOTE RATINGS
 
MOODY'S
          MIG1 & VMIG1
          Short-term municipal securities rated MIG1 or VMIG1 are of the best
          quality. They have strong protection from established cash flows,
          superior liquidity support or demonstrated broad-based access to the
          market for refinancing.

          MIG2 & VMIG2
          These Short-term municipal securities rated MIG2 or VMIG2 are of high
          quality. Margins of protection are ample although not so large as in
          the preceding group.

          MIG3 & VMIG3
          Favorable quality. All security elements are accounted for, but the
          undeniable strength of the preceding grades is lacking. Liquidity and
          cash flow protection may be narrow and marketing access for
          refinancing is likely to be less well established.
 
S&P
 
An S&P note rating reflects the liquidity concerns and market access risks
unique to notes. Notes due in three years or less will likely receive a note
rating. Notes maturing beyond three years will most likely receive a long-term
debt rating.
 
    SP-1 Strong capacity to pay principal and interest. Those issues determined
         to possess overwhelming safety characteristics will be given a plus (+)
         designation.
 
    SP-2 Satisfactory capacity to pay principal and interest.
 
    SP-3 Speculative capacity to pay principal and interest.

DESCRIPTION OF PREFERRED STOCK RATINGS
 
MOODY'S
 
     AAA Top-quality preferred stock. This rating indicates good asset
         protection and the least risk of dividend impairment within the
         universe of preferred stocks.
 
      AA High-grade preferred stock. This rating indicates that there is a
         reasonable assurance the earnings and asset protection will remain
         relatively well maintained in the foreseeable future.
 
       A Upper-medium grade preferred stock. While risks are judged to be
         somewhat greater than in the "aaa" and "aa" classification, earnings
         and asset protection are, nevertheless, expected to be maintained at
         adequate levels.
 
     BAA Medium-grade preferred stock, neither highly protected nor poorly
         secured. Earnings and asset protection appear adequate at present but
         may be questionable over any great length of time.
 
S&P
 
S&P's preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations.
 
    AAA Highest rating. This rating indicates an extremely strong capacity to
        pay the preferred stock obligations.
 
     AA High-quality, fixed-income security. The capacity to pay preferred stock
        obligations is very strong, although not as overwhelming as for issues
        rated "AAA."
 
       A Backed by a sound capacity to pay the preferred stock obligations,
         although it is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions.
 
    BBB Backed by an adequate capacity to pay the preferred stock obligations.
        Whereas the issuer normally exhibits adequate protection parameters,
        adverse economic conditions or changing circumstances are more likely to
        lead to a weakened capacity to make payments for a preferred stock in
        this category than for issues in the "A" category.
 
SHORT-TERM DEBT RATINGS
 
Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.
 
  TBW-1 Very high degree of likelihood that principal and interest will be paid
        on a timely basis.
 
  TBW-2 While degree of safety regarding timely repayment of principal and
        interest is strong, the relative degree is not as high as for issues
        rated TBW-1.
 
  TBW-3 Lowest investment grade category. While more susceptible to adverse
        developments than obligations with higher ratings, capacity to service
        principal and interest in a timely fashion is considered adequate.
 
  TBW-4 Non-investment grade and, therefore, speculative.

                          A BRIEF PREVIEW OF THE FUNDS
 
             WHAT ARE THE GOALS OF THE ONE GROUP BOND FUNDS?
             The Funds are designed for a variety of investment objectives,
             including current income consistent with the preservation of
             capital, current income with a primary focus on income that is
             exempt from state income taxes, and current income consistent
             with low volatility of principal. Each Fund pursues a
             different objective and involves different risks. Please read
             about each Fund before investing.
 
             WHAT ARE THE FUNDS' INVESTMENT STRATEGIES?
             The Intermediate Bond Fund, the Limited Volatility Bond Fund,
             the Ultra Short-Term Income Fund and the Income Bond Fund
             invest in high and medium grade debt securities of all types
             with average maturities ranging from one to fifteen years. The
             Income Bond Fund also may invest in lower grade debt
             securities, although it will limit its investments in such
             securities to no more than 30% of its total assets. The
             Government Bond Fund and the Treasury & Agency Fund invest in
             obligations issued or guaranteed by the U.S. government, its
             agencies and instrumentalities. Several of the Funds may
             invest in preferred stock.
 
             WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUNDS?
             The Funds invest in fixed-income investments that are subject
             to market fluctuations as a result of changes in interest
             rates. As a result, the value of investments in the Funds may
             decrease during periods of rising interest rates and increase
             during periods of declining interest rates. In addition, some
             of the Funds invest in mortgage-related securities which have
             significantly greater price and yield volatility than
             traditional fixed-income securities. Also, the Income Bond
             Fund may invest up to 30% of its total assets in securities in
             ANY rating category, some of which are regarded as
             predominately speculative. For more information about risks,
             please read "More About the Funds" and "Investment Risks."
 
             WHAT CLASSES OF SHARES ARE AVAILABLE?
             The Funds currently offer four classes of Shares: Class A,
             Class B, Class C and Fiduciary Class. Class A, Class B and
             Class C shares are offered to the general public. Fiduciary
             Class shares are offered to institutional investors, including
             affiliates of BANC ONE CORPORATION and any bank, depository
             institution, insurance company, pension plan or other
             organization authorized to act in fiduciary, advisory, agency,
             custodial or similar capacities. Fiduciary Class shares are
             not available to Individual Retirement Accounts ("IRA"). The
             section called "How To Do Business With The One Group" will
             provide more information.
 
             HOW DO I PURCHASE AND REDEEM SHARES?
   
             You may buy and redeem shares of the Funds on any day that the
             Funds are open for business. Class C shares are not available
             for purchase in all of the funds. Purchase and redemption
             procedures are explained in greater detail in "How To Do
             Business With The One Group." For additional information, call
             The One Group Services Company at 1-800-480-4111.
    
 
             HOW ARE DIVIDENDS PAID?
             Generally, dividends are declared on each business day and are
             distributed on the first business day of each month. Any
             capital gains are distributed at least annually. Distributions
             are paid in additional shares of the same class unless you
             elect to take the payment in cash. For a more detailed
             discussion of dividends, see "Dividend Policies."
 
             WHO MANAGES THE FUNDS?
             Banc One Investment Advisors Corporation ("Banc One Investment
             Advisors"), an indirect subsidiary of BANC ONE CORPORATION,
             serves as the advisor of the Funds. Banc One Investment
             Advisors is paid a fee for its services. A more detailed
             discussion regarding Banc One Investment Advisors, its
             services and compensation can be found in the Prospectus under
             the headings "The Advisor" and "Expense Summary."

THE ONE GROUP(R)
 
INTERMEDIATE BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks current income consistent with the preservation of capital by
investing in high and medium-grade fixed-income securities with intermediate
maturities.
 
[ICON] INVESTMENT STRATEGY
Generally, the Fund invests in debt securities of all types including bonds,
notes, U.S. Government obligations, and taxable and tax-exempt municipal
securities rated as investment grade at the time of investment, (or, if unrated,
determined by Banc One Investment Advisors, to be of comparable quality). The
fund's average weighted maturity will ordinarily range between three and ten
years, taking into account expected prepayment of principal on certain
investments, although the Fund may shorten the weighted average maturity to as
little as one year for temporary defensive purposes.
 
[ICON] PORTFOLIO SECURITIES
   
The Fund normally invests at least 80% of its total assets in debt securities.
Debt securities include bonds, notes and other obligations. As a matter of
fundamental policy, at least 65% of the Fund's total assets will consist of
bonds and at least 50% of total assets will consist of obligations issued by the
U.S. Government or its agencies and instrumentalities, some of which may be
subject to repurchase agreements. However, the Fund intends to hold at least 65%
of its total assets in such government obligations. Up to 20% of the Fund's
total assets may be invested in preferred stock. For a list of all the
securities in which the Fund may invest, please read "Investment Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund may invest in debt securities that are rated in the lowest investment
grade category. Such investments are considered to have speculative
characteristics. In addition, the Fund invests in fixed-income securities. The
value of these securities will change in response to interest rate changes and
other factors. This is especially true to the extent the Fund invests in debt
securities in the lowest investment grade category. The Fund also invests in

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .60% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.17% for Class A shares, 1.82% for Class B
    shares, 1.82% for Class C shares and .82% for Fiduciary Class shares.
 





 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
INCOME BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks a high level of current income by investing primarily in a
diversified portfolio of high, medium and low grade debt securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in all types of debt securities rated as investment grade or
below investment grade, as well as convertible securities, preferred stock, and
loan participations. The Fund's average weighted maturity will normally range
between five and twenty years, although the Fund may shorten its weighted
average to as little as two years if deemed appropriate for temporary defensive
purposes.
 
[ICON] PORTFOLIO SECURITIES
The Fund invests at least 70% of its total assets in debt securities of all
types rated as investment grade at the time of investment or, if unrated,
determined to be of comparable quality by Banc One Investment Advisors. In
addition, up to 30% of the Fund's total assets may be invested in convertible
securities, preferred stock, loan participations and debt securities rated below
investment grade or, if unrated, determined by Banc One Investment Advisors to
be of comparable quality. Securities rated below investment grade are called
"high yield bonds," "non-investment grade bonds" and "junk bonds." These
securities are rated in the fifth or lower rating categories (for example, BB or
lower by Standard & Poor's Corporation and Ba or lower by Moody's Investors
Service, Inc.), and are considered to be speculative. Even though it may invest
in debt securities in all rating categories, the Fund will not invest more than
20% of its total assets in securities rated below the fifth rating category. As
a matter of fundamental policy, at least 65% of the Fund's total assets will
consist of bonds. The Fund also may purchase taxable or tax-exempt municipal
securities. For a list of all the securities in which the Fund may invest,
please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in debt securities rated below investment grade that are
considered speculative. While these securities generally provide a higher yield
than higher rated debt securities, they are subject to a greater degree of risk.
Issuers of these securities may include smaller, less creditworthy companies or
highly indebted firms. The credit quality of securities in the high yield bond
market can change suddenly and unexpectedly. Before you invest, please read
"More About the Funds" and "Investment Risks."
 
[ICON] FUND MANAGEMENT
Roger A. Craig has been the manager of the Fund since 1993. Mr. Craig has served
as a fixed income manager for Banc One Investment Advisors and its affiliates
since 1986.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .60% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.17% for Class A shares, 1.82% for Class B
    shares, 1.82% for Class C shares and .82% for Fiduciary Class shares.





 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
GOVERNMENT BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks a high level of current income with liquidity and safety of
principal.
 
[ICON] INVESTMENT STRATEGY
The Fund limits its investments to securities issued by the U.S. Government and
its agencies and instrumentalities or related to securities issued by the U.S.
Government and its agencies and instrumentalities. The Fund's average weighted
remaining maturity will ordinarily range between three and fifteen years, taking
into account expected prepayment of principal on certain investments. However,
the Fund's average weighted remaining maturity may be outside this range if
warranted by market conditions.
 
[ICON] PORTFOLIO SECURITIES
   
At least 65% of the Fund's total assets will be invested in debt instruments
with principal and interest guaranteed by the U.S. Government or its agencies
and instrumentalities, some of which may be subject to repurchase agreements,
and other securities representing an interest in or secured by mortgages that
are issued or guaranteed by certain U.S. government agencies or
instrumentalities. For a list of all the securities in which the Fund may
invest, please read "Investment Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund's ability to achieve higher income is not as great as that of funds
that invest in lower-quality instruments. In addition, the Fund invests in
fixed-income securities. The value of these securities will change in response
to interest rate changes and other factors. The Fund also invests in
mortgage-related securities which may have greater price and yield volatility
than traditional fixed income securities. Before you invest, please read "More
About the Funds" and "Investment Risks."
 
[ICON] FUND MANAGEMENT
   
Thomas E. Donne, CFA, has been a Manager of the Fund since January, 1995. Since

Investment Advisors and its affiliates.
    
 
   
   Michael J. Sais, CFA, is head of mortgage research for Banc One Investment

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current expenses.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(5) Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
    would be 1.04% for Class A shares and 1.69% for Class B shares and Class C
    shares.

An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
ULTRA SHORT-TERM INCOME FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks a high level of current income consistent with low volatility of
principal by investing in a diversified portfolio of short-term investment grade
securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in all types of debt securities, including money market
instruments, adjustable rate mortgage backed securities and taxable and
tax-exempt municipal securities. The Fund will maintain a maximum duration
approximately equal to that of a two-year U.S. Treasury security, although the
Fund's actual duration is expected to be approximately equal to that of a one
year U.S. Treasury security.
 
[ICON] PORTFOLIO SECURITIES
The Fund normally invests at least 80% of its total assets in debt securities.
In addition, up to 20% of the Fund's total assets may be invested in other
securities, including preferred stock. The Fund will invest in adjustable rate
mortgage pass-through securities and other securities representing an interest
in or secured by mortgages with periodic interest rate resets (some of which may
be subject to repurchase agreements). These securities often are issued or
guaranteed by the U.S. Government, its agencies or instrumentalities. However,
the Fund may also purchase mortgage-backed securities that are issued by
non-governmental entities. Such securities may or may not have private insurer
guarantees of timely payments. For a list of all the securities in which the
Fund may invest, please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in fixed-income investments that are subject to market
fluctuations as a result of changes in interest rates. As a result, the value of
investments in the Fund may decrease during periods of rising interest rates. In
addition, the Fund invests in mortgage-related securities which may have greater

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .55% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the fee waiver, Other Expenses would be .31% for all classes of
    shares.
(7) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.21% for Class A shares, 1.80% for Class B
    shares, 1.80% for Class C shares, and .86% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
LIMITED VOLATILITY BOND FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks current income consistent with preservation of capital through
investment in high and medium-grade fixed-income securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests in all types of debt securities with short to intermediate
maturities. The Fund's average weighted maturity will ordinarily range between
one and five years taking into account expected prepayment of principal on
certain investments, although the Fund may shorten the weighted average maturity
to as little as 90 days for temporary defensive purposes.
 
[ICON] PORTFOLIO SECURITIES
   
The Fund invests at least 80% of its total assets in debt securities with short
to intermediate maturities. At least 65% of the Fund's total assets will consist
of bonds and at least 65% of total assets will consist of obligations issued by
the U.S. Government, its agencies, or instrumentalities (some of which may be
subject to repurchase agreements). The Fund also may purchase taxable or
tax-exempt municipal securities. Up to 20% the total assets may be invested in
preferred stock. For a list of all the securities in which the Fund may invest,
please read "Investment Practices."
    
 
[ICON] RISK CONSIDERATIONS
The Fund invests in fixed-income securities. The value of these securities will
change in response to interest rate changes and other factors. In addition, the
Fund invests in mortgage-related securities which may have greater price and
yield volatility than traditional fixed-income securities. Before you invest,
please read "More About the Funds" and "Investment Risks."
 
[ICON] FUND MANAGEMENT
Roger A. Craig has been the manager of the Fund since November, 1996. Mr. Craig
has served as a fixed income manager for Banc One Investment Advisors and its
affiliates since 1986.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Without the fee waiver, Investment Advisory Fees would be .60% for all
    classes of shares.
(5) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .35% for Class A
    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be 1.17% for Class A shares, 1.82% for Class B
    shares, 1.82% for Class C shares and .82% for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.

    shares and 1.00% for Class B and Class C shares.
(6) Without the voluntary reduction, Other Expenses would be .36% for all
    classes of shares.
(7) Without the voluntary reduction of fees, Total Operating Expenses would be

PORTFOLIO QUALITY
- ----------------------------------------------------
 
The Funds only purchase securities that meet the following criteria.
 
DEBT SECURITIES
 
- - The Limited Volatility Bond Fund, the Government Bond Fund and the Treasury &
  Agency Fund may invest in debt securities rated in any of the three highest
  investment grade rating categories.
 
- - The Ultra Short-Term Income Fund and the Intermediate Bond Fund may invest in
  debt securities rated in any of the four investment grade rating categories.
 
- - The Income Bond Fund may purchase securities in ANY rating category. Please
  read "Special Risk Considerations" and "High Yield/Junk Bonds" for more
  information about the Income Bond Fund.
 
PREFERRED STOCK
 
- - The Ultra Short-Term Income Fund and the Intermediate Bond Fund may only
  invest in preferred stock rated in one of the four highest rating categories.
 
- - Preferred stock purchased by the Limited Volatility Bond Fund must be rated in
  one of the three highest rating categories.
 
- - The Income Bond Fund may invest in preferred stock in ANY rating category.
 
MUNICIPAL SECURITIES
 
- - The Intermediate Bond Fund and the Ultra Short-Term Income Fund may only
  invest in municipal bonds rated in one of the four highest rating categories.
 
- - Municipal bonds purchased by the Limited Volatility Bond Fund must be rated in
  one of the three highest rating categories.
 
- - The Intermediate Bond Fund and the Ultra Short-Term Income Fund may only
  invest in other municipal securities, such as tax-exempt commercial paper,
  notes and variable rate demand obligations that are rated in the highest or
  second highest rating categories. The Limited Volatility Bond Fund may invest
  in such securities only if they are rated in the highest rating category.
 
   
- - The Income Bond Fund may invest in municipal securities rated in ANY category.
    
 
If the securities are unrated, Banc One Investment Advisors must determine that
they are of comparable quality to rated securities. Banc One Investment Advisors
will look at a security's rating at the time of investment. For more information
about ratings, please see "Description of Ratings" in the Appendix.
 
ILLIQUID INVESTMENTS
- ----------------------------------------------------
 
Each Fund may invest up to 15% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by The One Group Board of Trustees in determining whether an
investment is illiquid.
 
SPECIAL RISK
CONSIDERATIONS
- ----------------------------------------------------
 
   
FIXED INCOME SECURITIES: Investments in fixed income securities (for example,
bonds) will increase or decrease in value based on changes in interest rates. If
rates increase, the value of a Fund's investments generally declines. On the
other hand, if rates fall, the value of the investments generally increases. The
value of your investment in a Fund will increase and decrease as the value of a
Fund's investments increase and decrease. While securities with longer duration
and maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually, changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment.
    
 
DERIVATIVES: Some of the Funds invest in securities that are considered to be
derivatives. These securities may be more volatile than other investments. These
include:
 
- - options, futures contracts, and options on futures contracts
 
- - mortgage-backed securities, including collateralized mortgage obligations and
  Real Estate Mortgage Investment Conduits (CMOs and REMICs) and stripped
  mortgage-backed securities (IOs and POs)
 
- - asset-backed securities
 
- - swap, cap and floor transactions
 
- - new financial products
 
- - structured instruments
 
- - inverse floating rate instruments
<PAGE>   124
 
                                                                              21
 
Derivatives may be riskier than traditional investments.
 
LOWER RATED SECURITIES: The Intermediate Bond Fund, the Ultra Short-Term Income
Fund and the Income Bond Fund may invest in debt securities rated in the lowest
investment grade category. Securities in this rating category are considered to
have speculative characteristics. Changes in economic conditions or other
circumstances may have a greater effect on the ability of issuers of these
securities to make principal and interest payments than they do on issuers of
higher grade securities.
 
HIGH YIELD/JUNK BONDS: The Income Bond Fund may invest in debt securities rated
below investment grade. These securities are regarded as predominately
speculative. Lower rated securities generally provide a higher yield than higher
rated debt securities of similar maturity, but are subject to a greater degree
of risk that the issuer may not be able to make principal and interest payments.
Issuers of these securities may not be as strong financially as those issuing
higher rated securities. Such high yield issuers may include smaller, less
creditworthy companies or highly indebted firms.
 
The market value of high yield securities may fluctuate more than the market
value of higher rated securities, since high yield securities tend to reflect
short-term corporate and market developments to a greater extent than higher
rated securities. Thus, periods of economic uncertainty and change can result in
the increased volatility of market prices of high yield bonds and of the
investment company's net asset value. Additional risks of high yield securities
include limited liquidity and secondary market support. As a result, the prices
of high yield securities may decline rapidly in the event that a significant
number of holders decide to sell. Issuers of high yield securities also are more
vulnerable to real or perceived economic changes, political changes or adverse
developments specific to the issuer. A projection of an economic downturn, for
example, could cause the price of these securities to decline because a
recession could lessen the ability of a highly leveraged company to make
principal and interest payments on its debt securities. In the event of a
default, the Income Bond Fund would experience a decrease in income and a
decline in the market value of its investments. In addition, a long-term track
record on bond default rates, such as that for investment grade corporate bonds,
does not exist for the high yield market. It may be that future default rates on
high-yield bonds will be more widespread and higher than in the past, especially
during periods of deteriorating economic conditions.
 
Finally, the market prices of debt securities generally fluctuate with changes
in interest rates so that the Income Bond Fund's net asset value can be expected
to decrease as long-term interest rates rise and to increase as long-term rates
fall. The market prices of high yield securities structured as zero coupon or
pay-in-kind securities are generally affected to a greater extent by interest
rate changes and tend to be more volatile than securities which pay interest
periodically.
 
Credit quality in the high yield bond market can change suddenly and
unexpectedly, and even recently-issued credit ratings may not fully reflect the
actual risks posed by a particular high-yield security. For these reasons, the
Income Bond Fund will not rely solely on ratings issued by established credit
rating agencies, but will use such ratings in conjunction with Banc One
Investment Advisors' independent and ongoing review of credit quality.
 
Because investments in lower rated securities involve greater investment risk,
achievement of the Income Bond Fund's investment objectives may be more
dependent on Banc One Advisor's credit analysis than would be the case if the
Income Bond Fund were investing in higher rated securities. The Income Bond Fund
may seek to hedge investments through transactions in options, futures contracts
and related options. The Income Bond Fund also may use swap agreements to
further manage exposure to lower rated securities.

  sponsors, or other intermediaries. Shares purchased this way will be held for
  you by the Shareholder Servicing Agent.
 
WHEN CAN I BUY SHARES?
 
- - Purchases may be made on any business day. This includes any day that the
  Funds are open for business, other than weekends and the following holidays:
  New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
  Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas.
 
- - Purchase requests received by The One Group Services Company before 4 p.m.
  Eastern Standard Time ("EST"), will be effective that day.
 
- - Purchase orders may be canceled by the Fund's Custodian, State Street Bank and
  Trust Company, if it does not receive "federal funds" by 4:00 p.m. EST (i) on
  the business day after the order is placed if you are buying Fiduciary Class
  shares, and (ii) on the third business day if you are purchasing Class A,
  Class B or Class C shares.
 
- - If your shares are held by a Shareholder Servicing Agent, it is the
  responsibility of the Shareholder Servicing Agent to send your purchase or
  redemption order to the Fund. Your Shareholder Servicing Agent may have an
  earlier cut-off time for purchase and redemption requests.
 
- - The One Group Services Company can reject a purchase order if it does not
  think that it is in the best interests of a Fund and/or its shareholders to
  accept the order.
 
- - Shares are electronically recorded. Therefore, certificates will not be
  issued.
 
WHAT KIND OF SHARES CAN I BUY?
 
The One Group offers the following classes of shares:
 
- - Class A, Class B and Class C shares are available to the general public.
 
- - Fiduciary Class shares are available to institutional investors and any
  organization authorized to act in a fiduciary, advisory, custodial or agency
  capacity. We will refer to these entities as "Intermediaries."
 
- - If you intend to hold your shares six or more years, Class B shares may be
  appropriate for you. If you intend to hold your shares for less than six
  years, you may want to consider Class A or Class C shares.
 
   
The One Group Fund Direct IRA. The One Group offers a retirement plan and, in
1998, will offer an education plan. These plans allow participants to defer
taxes while their retirement and education savings grow. The education IRA
requires a minimum investment of $500. Call The One Group Services Company at
1-800-480-4111 for an Adoption Agreement.
    
 
HOW MUCH DO SHARES COST?
 
- - Shares are sold at net asset value ("NAV") plus a sales charge, if any.
 
- - Each class of shares in each Fund has a different NAV. This is primarily
  because each class has different distribution expenses.
 
- - NAV per share is calculated by dividing the total market value of a Fund's
  investments and other assets allocable to a class (minus class expenses) by
  the number of outstanding shares in that class.
 
- - A Fund's NAV changes every day. NAV is calculated each business day at 4:00
  p.m. EST.
 
HOW DO I OPEN AN ACCOUNT?
 
1. Read the prospectus carefully, and select the Fund or Funds most appropriate
   for you.
 
2. Decide how much you want to invest.
 
   - The minimum initial investment for all Funds except the Treasury & Agency

     is $50,000.
 
   - Subsequent investments for all Funds except the Treasury & Agency Fund must
     be at least $100 ($25 for employees of BANC ONE CORPORATION and its

   - The One Group Services Company may waive these minimums.

   Account privileges that you plan to take advantage of. Doing so now means
   that you will not have to complete additional paperwork later.

   exchanges and redemptions.
 
7. If you have any questions, contact your Shareholder Servicing Agent or call
   The One Group Services Company at 1-800-480-4111.
 
CAN I PURCHASE SHARES OVER THE TELEPHONE?
 
Yes, simply select this option on your Account Application Form and then:
 
- - Contact your Shareholder Servicing Agent or The One Group Services Company at
  1-800-480-4111 to relay your purchase instructions.
 
- - Send a personal check made payable to "The One Group" to State Street Bank and
  Trust Company (see address above), to authorize a bank transfer or initiate a
  wire transfer.
 
- - The One Group uses reasonable procedures to confirm that instructions given by
  telephone are genuine. These procedures include recording telephone
  instructions and asking for personal identification. If these procedures are
  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
   
- - You may revoke your right to make purchases over the telephone by sending a
  letter to:
    
 
  State Street Bank and Trust Company
  c/o The One Group
  P.O. Box 8500
  Boston, MA 02266-8500
 
CAN I AUTOMATICALLY INVEST ON A
SYSTEMATIC BASIS?
 
Yes, except for The Treasury & Agency Fund. After your Account is established,
you may purchase additional Class A, Class B and Class C shares by making
automatic monthly investments from your bank account. The minimum initial
investment is still $1,000, but minimum automatic additions are only $25. The
One Group Services Company may waive these minimums. To establish a Systematic
Investment Plan:
 
- - Select the "Systematic Investment Plan" option on the Account Application
  Form.
 
- - Provide the necessary information about the bank account from which your
  investments will be made.
 
- - Shares purchased under a Systematic Investment Plan may not be redeemed for
  ten (10) calendar days.
 
- - The One Group currently does not charge for this service, but may impose a
  charge in the future. However, your bank may impose a charge for debiting your
  bank account.
 
   
- - You may revoke your right to make systematic investments by sending a letter
  to:
    
 
  State Street Bank and Trust Company
  c/o The One Group
  P.O. Box 8500
  Boston, MA 02266-8500
 
CONVERSION FEATURE
 
- - Your Class B shares automatically convert to Class A shares. Class B shares of
  the Intermediate Bond Fund, the Income Bond Fund, and the Government Bond Fund
  automatically convert to Class A shares after eight years.
 
- - Class B shares of the Ultra Short-Term Income Fund, the Limited Volatility
  Bond Fund, and the Treasury & Agency Fund automatically convert to Class A
  shares after six years.
 
- - Conversion periods are measured from the end of the month in which the Class B
  shares were purchased.
 
   
- - After conversion, your shares will be subject to the lower distribution and
  shareholder servicing fees charged on Class A shares.
    
 
- - You will not be assessed any sales charges or fees for conversion of shares,
  nor will you be subject to any tax.
 
- - Because the share price of the Class A shares may be higher than that of the
  Class B shares at the time of conversion, you may receive fewer Class A
  shares; however, the dollar value will be the same.
 
- - If you have exchanged Class B shares of one Fund for Class B shares of
  another, the time you held the shares in each Fund will be added together for
  purposes of calculating the six and eight year time periods.

Or if you redeem Class B shares of the ULTRA SHORT-TERM INCOME FUND, THE LIMITED
VOLATILITY BOND FUND OR THE TREASURY & AGENCY FUND prior to the fourth
anniversary of purchase, you will be assessed a CDSC according to the following
schedule:

The One Group Services Company pays a commission of 4.00% of the original
purchase to Shareholder Servicing Agents who sell Class B shares of the
Intermediate Bond Fund, the Income Bond Fund and the Government Bond Fund.
Shareholder Servicing Agents who sell Class B shares of the Ultra Short-Term
Income Fund, the Limited Volatility Bond Fund and the Treasury & Agency Fund
receive a commission of 2.75% from The One Group Services Company.
 
 CLASS C SHARES
 
Class C shares are offered at NAV, without any up-front sales charge. However,
if you redeem your shares within one year of the purchase date, you will be
assessed a CDSC as follows:
 
<TABLE>
<CAPTION>
                          CDSC AS A % OF DOLLAR

  After first year                  None
</TABLE>
 
Shareholder Servicing Agents selling Class C shares receive a commission of
1.00% of the original purchase price from The One Group Services Company.
 
How the CDSC is Calculated
 
- - The Fund assumes that all purchases made in a given month were made on the
  first day of the month.
 
- - The CDSC is based on the current market value or the original cost of the
  shares, whichever is less.
 
- - A sales charge is not imposed on increases in NAV above the initial purchase
  price, nor is a sales charge assessed on shares acquired through reinvestment
  of dividends or capital gains distributions.
 
- - To keep your CDSC as low as possible, the Fund first will redeem any shares in
  your account that carry no CDSC, starting with Class A shares. After that, the
  Fund will redeem the shares you have held for the longest time and thus have
  the lowest CDSC.
<PAGE>   129
 
26
 
12B-1 FEES
 
12b-1 fees are paid by The One Group to The One Group Services Company as
compensation for its services and expenses. The One Group Services Company in
turn pays all or part of the 12b-1 fee to Shareholder Servicing Agents that sell
shares of The One Group.
 
- - The 12b-1 fees vary by share class as follows:
 
   1. Class A shares pay a 12b-1 fee of .35% of the average daily net assets of
      the Fund, which is currently being waived to .25%.
 
   2. Class B and Class C shares pay a 12b-1 fee of 1.00% of the average daily
      net assets of the Fund, which is currently being waived to .90% for the
      Intermediate Bond Fund, the Income Bond Fund, and the Government Bond Fund
      and to .75% for the Limited Volatility Bond Fund, the Ultra Short-Term
      Income Fund, and the Treasury & Agency Fund. This will cause expenses for
      Class B and Class C shares to be higher and dividends to be lower than for
      Class A shares.
 
   3. There are no 12b-1 fees for Fiduciary Class shares.
 
- - 12b-1 fees, together with the CDSC, help The One Group Services Company sell
  Class B and Class C shares without an "up-front" sales charge by defraying the
  costs of advancing brokerage commissions and other expenses paid to
  Shareholder Servicing Agents.
 
- - The One Group Services Company may use up to .25% of the fees for shareholder
  servicing and up to .75% for distribution. During the last fiscal year, The
  One Group Services Company received 12b-1 fees totaling .25% of the average
  daily net assets of the Class A shares of the Funds. In addition, The One
  Group Services Company received 12b-1 fees totaling .90% of the average daily
  net assets of the Class B shares of the Intermediate Bond Fund, the Income
  Bond Fund, and the Government Bond Fund, and .75% for Class B shares of the
  Limited Volatility Bond Fund, the Ultra Short-Term Income Fund, and the
  Treasury & Agency Fund.
 
- - The One Group Services Company may pay
   12b-1 fees to its affiliates and to Banc One Investment Advisors and its
   affiliates (or any sub-advisor) for brokerage and other agency transactions.
 
SALES CHARGE
REDUCTIONS
AND WAIVERS
- ----------------------------------------------------
 
REDUCING YOUR CLASS A SALES CHARGES
 
There are several ways you can reduce the sales charges you pay on Class A
shares:
 
1. Right of Accumulation: You may add the market value of any Class A, Class B
   or Class C shares of a Fund (except a money market fund) that you (and your
   spouse and minor children) already own to the amount of your next Class A
   purchase for purposes of calculating the sales charge. An Intermediary also
   may take advantage of this option.
 
2. Letter of Intent: With an initial investment of $2,000, you may purchase
   Class A shares of one or more Funds over the next 13 months and pay the same
   sales charge that you would have paid if all shares were purchased at once. A
   percentage of your investment will be held in escrow until the full amount
   covered by the Letter of Intent has been invested.
 
To take advantage of the accumulation privilege or letter of intent, complete
the appropriate section of your fund application, or contact your Shareholder
Servicing Agent. To determine if you are eligible for the accumulation
privilege, contact The One Group Services Company at 1-800-480-4111. These
programs may be terminated or amended at any time.
 
WAIVER OF THE CLASS A SALES CHARGE
 
No sales charge is imposed on Class A shares of the Funds if the shares were:
 
1. Bought with the reinvestment of dividends and capital gains distributions.
 
2. Acquired in exchange for other Fund shares if a comparable sales charge has
   been paid for the exchanged shares.
 
3. Bought by officers, directors or trustees, retirees and employees (and their
   spouses and immediate family members) of:
 
   - The One Group.

     Agents who place trades for their own accounts if the accounts are linked
     to the master account of such Shareholder Servicing Agent.
 
5. Bought with proceeds from the sale of Fiduciary Class shares of a Fund of The
   One Group or acquired in an exchange of Fiduciary Class shares of a Fund for
   Class A shares of the same Fund, but only if the purchase is made within 60
   days of the sale or distribution.
 
6. Bought with proceeds from the sale of shares of a mutual fund (other than a
   fund of The One Group) for which a sales charge was paid, but only if the

- - Fiduciary Class shares of a Fund may be exchanged for Class A shares of that
  Fund or for Class A or Fiduciary Class shares of another Fund of The One
  Group.
 
- - Class A shares of a Fund may be exchanged for Fiduciary Class shares of that
  Fund or for Class A or Fiduciary Class shares of another Fund of The One
  Group, but only if you are eligible to purchase those shares.
 
- - Class B shares of a Fund may be exchanged for Class B shares of another Fund
  of The One Group.
 
- - Class C shares of a Fund may be exchanged for Class C shares of another Fund
  of The One Group.
 
The One Group does not charge a fee for this privilege. In addition, The One
Group may change the terms and conditions of your exchange privileges upon 60
days written notice.
 
WHEN ARE EXCHANGES PROCESSED?
 
Exchanges are processed the same business day they are received, provided:
 
- - State Street Bank and Trust Company receives the request by 4:00 p.m., EST.
 
- - You have provided The One Group with all of the information necessary to
  process the exchange.
 
- - You have received a current prospectus of the Fund or Funds in which you wish
  to invest.
 
- - You have contacted your Shareholder Servicing Agent, if necessary.
 
DO I PAY A SALES CHARGE ON AN EXCHANGE?
 
Generally, you will not pay a sales charge on an exchange. However:
 
- - You will pay a sales charge if you own Fiduciary Class shares of a Fund and
  you want to exchange those shares for Class A shares, unless you qualify for a
  sales charge waiver (see above).
 
- - You will pay a sales charge if you bought Class A shares of a Fund:
 
   1. That does not charge a sales charge and you want to exchange them for
      shares of a Fund that does, in which case you would pay the sales charge
      applicable to the Fund into which you are exchanging.
 
   2. That charged a lower sales charge than the Fund into which you are
      exchanging, in which case you would pay the difference between that Fund's
      sales charge and all other sales charges you have already paid.
 
- - If you exchange Class B or Class C shares of a Fund, you will not pay a sales
  charge the time of the exchange, however:
 
   1. Your new Class B or Class C shares will be subject to the higher CDSC of
      either the Fund from which you exchanged, the Fund into which you
      exchanged, or any Fund from which you previously exchanged.
 
   2. The current holding period for your exchanged Class B or Class C shares is
      carried over to your new shares.
 
ARE EXCHANGES TAXABLE?
 
Generally:
 
- - An exchange between classes of shares of the same Fund is not taxable.
 
- - An exchange between Funds is considered a sale and generally results in a
  capital gain or loss for Federal income tax purposes.
 
- - You should talk to your tax advisor before making an exchange.
 
ARE THERE LIMITS ON EXCHANGES?
 
Yes. The exchange privilege is not intended as a way for you to speculate on
short-term movements in the market. Therefore:
 
- - To prevent disruptions in the management of the Funds, The One Group limits
  excessive exchange activity.
 
- - Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
  REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH PERIOD.
 
   
- - In addition, The One Group reserves the right to reject any exchange request
  (even those that are not excessive) if the Fund reasonably believes that the
  exchange will result in excessive transaction costs or otherwise adversely
  affect other shareholders.

  Program or the Stock Exchange Medallion Program, unless:
 
   1. the redemption is for $50,000 worth of shares or less;
 
   2. the redemption is payable to the shareholder of record; and
 
   3. the redemption check is mailed to the shareholder at the record address.
 
- - On the Account Application Form, you may elect to have the redemption proceeds
  mailed or wired to:
 
   
   1. a designated commercial bank; or
    
 
   2. State Street Bank and Trust Company or your Shareholder Servicing Agent.
 
   
- - State Street Bank and Trust Company may charge you a wire redemption fee. The

- - If you own Class A and Fiduciary Class shares and the Fund receives your
  redemption request by 4:00 p.m. EST, you will receive that day's NAV.
 
- - If you own Class B or Class C shares and the Fund receives your redemption
  request by 4:00 p.m. EST, you will receive that day's NAV, minus the amount of
  any applicable CDSC.
 
CAN I REDEEM BY TELEPHONE?
 
Yes, if you selected this option on your Account Application Form.
 
- - Call your Shareholder Servicing Agent or State Street Bank and Trust Company
  at 1-800-480-4111 to relay your redemption request.
 
- - Your redemption proceeds will be mailed or wired to the commercial bank
  account you designated on your Account Application Form.
 
- - State Street Bank and Trust Company may charge you a wire redemption fee. The

  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
- - REDEMPTIONS FROM YOUR IRA ACCOUNT MAY NOT BE MADE BY TELEPHONE.
 
CAN I REDEEM ON A SYSTEMATIC BASIS?
 
If you have an account value of at least $10,000 you may elect to receive
monthly, quarterly or annual payments of not less than $100 each.
 
- - Select the "Systematic Withdrawal Plan" option on the Account Application
  Form.
 
- - Specify the amount you wish to receive and the frequency of the payments.
 
- - You may designate a person other than yourself as the payee.
 
- - There is no charge for this service.
 
- - If you select this option, please keep in mind that:
 
   1. It may not be in your best interest to buy additional Class A shares while
      participating in a Systematic Withdrawal Plan. This is because Class A
      shares have an up-front sales charge.
 
   2. If you own Class B or Class C shares, you or your designated payee may
      receive systematic payments provided the payments are limited to no more
      than 10% of your account value annually, measured from the date the
      redemption request is received.
 
   3. If you are age 70 1/2, you may elect to receive payments to the extent
      that the payment represents a minimum required distribution from an IRA or
      other qualifying retirement plan. These payments may be less than $100
      each.
 
   4. If the amount of the systematic payment exceeds the income earned by your
      account since the previous payment under the Systematic Withdrawal Plan,
      payments will be
<PAGE>   133
 
30
 
      made by redeeming some of your shares. This will reduce the amount of your
      investment.
 
ADDITIONAL INFORMATION REGARDING REDEMPTIONS
 
- - All redemptions will be for cash.
 
- - If you redeem shares for which you paid by check, and The One Group has not
  yet received payment on the check, The One Group will delay forwarding your
  redemption proceeds for 10 or more days until payment has been collected from
  your bank.
 
- - Because of the high cost of handling small investments, The One Group will
  automatically redeem shares in accounts which, because of shareholder
  redemptions, have values of less than $1,000. No sales charges will be
  assessed and you will be given 60 days to make additional investments in the
  Fund to increase the value of your account to at least $1,000.
 
- - The One Group may suspend your ability to redeem, or will redeem your shares
  involuntarily, when it seems appropriate to do so in light of its
  responsibilities under the Federal securities laws. The Statement of
  Additional Information offers more details about this process.

                            SHAREHOLDER INFORMATION
 
                                                                              31
 
VOTING RIGHTS
- ----------------------------------------------------
 
The Funds do not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change a Fund's fundamental investment objective, or approve an
investment advisory contract.
 
As a Fund shareholder, you have one vote for each share that you own. Each Fund,
and each class of shares within each Fund, vote separately on matters relating
solely to that Fund or class, or which affect that Fund or class differently.
However, all shareholders will have equal voting rights on matters that affect
all shareholders equally.

BANC ONE CORPORATION (100 East Broad Street, Columbus, Ohio, 43271), through its
affiliates, may be deemed for purposes of the Investment Company Act of 1940 to
control the Funds. This is because as of August 5, 1997, BANC ONE CORPORATION or
its affiliates possessed the power to vote substantially all of the Fiduciary
Class shares of the Funds.
 
On the same date, the following shareholders owned 25% or more of Class A or    
Class B shares of the Fund. As a consequence, they are considered to be
controlling persons of these classes of the Fund listed below.

DIVIDEND POLICIES
- ----------------------------------------------------
 
DIVIDENDS
 
The Funds generally declare dividends on each business day. Dividends are
distributed on the first business day of each month. Capital gains, if any, for
all Funds are distributed at least annually. To maintain a relatively even rate
of distributions from the Treasury & Agency Fund, the monthly distributions for
that Fund may be fixed from time to time at rates consistent with Banc One
Investment Advisors' long-term earnings expectations.
 
Dividends payable on Fiduciary Class shares will be more than those payable on
other classes of shares. This is because Class A, Class B and Class C shares
have higher distribution expenses.
 
The Funds pay dividends and distributions on a per-share basis. This means that
the value of your shares will be reduced by the amount of the payment. If you
purchase shares shortly before the record date for a dividend or the
distribution of capital gains, you will pay the full price for the shares and
receive some portion of the price back as a taxable dividend or distribution.
 
DIVIDEND REINVESTMENT
 
You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund and class, unless you have
elected to take such payment in cash. The price of the shares is the NAV
determined immediately following the dividend record date. Reinvested dividends
and distributions receive the same tax treatment as dividends and distributions
paid in cash.
 
If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8500, Boston, MA
02266-8500, at least 15 days prior to the distribution. The change is effective
upon receipt by State Street.
<PAGE>   135
 
32
 
SPECIAL DIVIDEND RULES FOR CLASS B SHARES
 
Class B shares received as dividends and capital gains distributions will be
accounted for separately. Each time any Class B shares (other than those in the
sub-account) convert to Class A shares, a percentage of the Class B shares in
the sub-account will also convert to Class A shares. (See "Conversion Feature.")
 
TAX TREATMENT
OF THE FUNDS
- ----------------------------------------------------
 
TAX STATUS OF THE FUND
 
Each Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Funds qualify, as they have in the past, they will
pay no federal income tax on the earnings they distribute to shareholders.
 
TAX TREATMENT
OF SHAREHOLDERS
- ----------------------------------------------------
 
TAXATION OF SHAREHOLDER TRANSACTIONS
 
A sale, exchange, or redemption of Fund shares generally will produce either a
taxable gain or a loss. You are responsible for any tax liabilities generated by
your transactions.
 
TAXATION OF DISTRIBUTIONS
 
Each Fund will distribute substantially all of its net investment income
(including net short-term capital gains) on at least an annual basis. Dividends
you receive from a Fund, whether reinvested or received in cash, will be taxable
to you. Dividends from a Fund's net investment income will be taxable as
ordinary income and dividends from a Fund's long-term capital gains will be
taxable to you as such, regardless of how long you have held the shares.
 
Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid the previous December.
 
TAXATION OF RETIREMENT PLANS
 
Distributions by the Funds to qualified retirement plans will not be taxable.
However, if shares are held by a plan that ceases to qualify for tax-exempt
treatment or by an individual who has received the shares as a distribution from
a retirement plan, the distributions will be taxable to the plan or individual
as described in "Taxation of Distributions." If you are considering purchasing
shares with qualified retirement plan assets, you should consult your tax
advisor for a more complete explanation of the Federal, state, local and (if
applicable) foreign tax consequences of making such an investment.
 
TAX INFORMATION
 
The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Funds provide you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Funds or their shareholders.

INVESTMENT RISKS
- ----------------------------------------------------
 
Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities held by the Funds may fluctuate, as will the value of
your investment in the Funds. Certain investments are more susceptible to these
risk than others.
 
- - CREDIT RISK. The risk that the issuer of a security, or the counterparty to a
  contract, will default or otherwise become unable to honor a financial
  obligation. Credit risk is generally higher for non-investment grade
  securities. The price of a security can be adversely affected prior to actual
  default as its credit status deteriorates and the probability of default
  rises.
 
   
- - LEVERAGE RISK. The risk associated with securities or practices (such as
  borrowing) that multiply small index or market movements into large changes in
  value. Leverage is often associated with investments in derivatives, but also
  may be embedded directly in the characteristics of other securities.
    
 
   - HEDGED. When a derivative (a security whose value is based on another
     security or index) is used as a hedge against an opposite position that the
     fund also holds, any loss generated by the derivative should be
     substantially offset by gains on the hedged investment, and vice versa.
     While hedging can reduce or eliminate losses, it can also reduce or
     eliminate gains. Hedges are sometimes subject to imperfect matching between
     the derivative and underlying security, and there can be no assurance that
     a Fund's hedging transactions will be effective.
 
   - SPECULATIVE. To the extent that a derivative is not used as a hedge, the
     fund is directly exposed to the risks of that derivative. Gains or losses
     from speculative positions in a derivative may be substantially greater
     than the derivative's original cost.
 
- - LIQUIDITY RISK. The risk that certain securities may be difficult or
  impossible to sell at the time and the price that would normally prevail in
  the market. The seller may have to lower the price, sell other securities
  instead or forego an investment opportunity, any of which could have a
  negative effect on fund management or performance. This includes the risk of
  missing out on an investment opportunity because the assets necessary to take
  advantage of it are tied up in less advantageous investments.
 
- - MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
  to produce the intended result. This includes the risk that changes in the
  value of a hedging instrument will not match those of the asset being hedged.
  Incomplete matching can result in unanticipated risks.
 
- - MARKET RISK. The risk that the market value of a security may move up and
  down, sometimes rapidly and unpredictably. These fluctuations may cause a
  security to be worth less than the price originally paid for it, or less than
  it was worth at an earlier time. Market risk may affect a single issuer,
  industry, sector of the economy or the market as a whole. There is also the
  risk that the current interest rate may not accurately reflect existing market
  rates. For fixed income securities, market risk is largely, but not
  exclusively, influenced by changes in interest rates. A rise in interest rates
  typically causes a fall in values, while a fall in rates typically causes a
  rise in values. Finally, key information about a security or market may be
  inaccurate or unavailable. This is particularly relevant to investments in
  foreign securities.
 
- - POLITICAL RISK. The risk of losses attributable to unfavorable governmental or
  political actions, seizure of foreign deposits, changes in tax or trade
  statutes, and governmental collapse and war.
 
- - FOREIGN INVESTMENT RISK. Associated with higher transaction costs, delayed
  settlements, currency controls and adverse economic developments. This
  includes the risk that fluctuations in the exchange rates between the U.S.
  dollar and foreign currencies may negatively affect an investment. Adverse
  changes in exchange rates may erode or reverse any gains produced by foreign
  currency denominated investments and may widen any losses. Exchange rate
  volatility also may affect the ability of an issuer to repay U.S. dollar
  denominated debt, thereby increasing credit risk.
 
- - PRE-PAYMENT RISK. The risk that the principal repayment of a security will
  occur at an unexpected time, especially that the repayment of a mortgage or
  asset-backed security occurs either significantly sooner or later than
  expected. Changes in pre-payment rates can result in
<PAGE>   141
 
38
 
  greater price and yield volatility. When mortgage and other obligations are
  pre-paid, a Fund may have to reinvest in securities with a lower yield.
  Further, with early prepayment, a Fund may fail to recover any premium paid,
  resulting in an unexpected capital loss.
 
- - TAX RISK. The risk that the issuer of the securities will fail to comply with
  certain requirements of the Internal Revenue Code, which would cause adverse
  tax consequences.
 
- - REGULATORY RISK. The risk associated with Federal and state laws which may
  restrict the remedies that a mortgage lender has when a borrower defaults on
  mortgage loans. These laws include restrictions on foreclosures, redemption
  rights after foreclosure, Federal and state bankruptcy and debtor relief laws,
  restrictions on "due on sale" clauses, and state usury laws.
 
INVESTMENT POLICIES
- ----------------------------------------------------
 
Each Fund's investment objective and the following investment policies
summarized below are fundamental. This means that they cannot be changed without
the consent of a majority of the outstanding shares of the Funds. In addition to
the fundamental policies mentioned earlier, the following fundamental policies
apply to each Fund as specified. The full text of the fundamental policies can
be found in the Statement of Additional Information.
 
Each Fund may not:
 
1. Purchase the securities of an issuer if as a result more than 5% of its total
   assets would be invested in the securities of that issuer or the Fund would
   own more than 10% of the outstanding voting securities of that issuer. This
   does not include securities issued or guaranteed by the United States, its
   agencies or instrumentalities, securities of registered investment companies,
   and repurchase agreements involving these securities. This restriction
   applies with respect to 75% of a Fund's total assets.
 
   
2. Concentrate their investment in the securities of one or more issuers
   conducting their principal business in a particular industry or group of
   industries. This does not include obligations issued or guaranteed by the
   U.S. Government or its agencies and instrumentalities and repurchase
   agreements involving such securities.
    
 
3. Make loans, except that a Fund may (i) purchase or hold debt instruments in
   accordance with its investment objective and policies; (ii) enter into
   repurchase agreements; and (iii) engage in securities lending.
 
Additional investment policies are set forth in the Statement of Additional
Information.
 
TEMPORARY DEFENSIVE POSITION
 
For temporary defensive purposes as determined by Banc One Investment Advisors,
the Funds may invest up to 100% of their assets in money market instruments, and
may hold a portion of their assets in cash for liquidity purposes. While the
Funds are engaged in a temporary defensive position, they will not be pursuing
their investment objectives. Therefore, the Funds will pursue a temporary
defensive position only when market conditions warrant.
 
PORTFOLIO TURNOVER
 
Portfolio turnover may vary greatly from year to year, as well as within a
particular year.
 
Higher portfolio turnover rates will likely result in higher transaction costs
to the Funds and may result in additional tax consequences to you. The portfolio
turnover rate for each Fund for the fiscal year ended June 30, 1997 is shown on
the Financial Highlights.

DESCRIPTION OF RATINGS
 
The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.
 
Unrated securities will be treated as non-investment grade securities unless
Banc One Investment Advisors determines that such securities are the equivalent
of investment grade securities. Securities that have received different ratings
from more than one agency are considered investment grade if at least one agency
has rated the security investment grade.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
 
DUFF & PHELPS CREDIT RATING CO. ("DUFF")
 
    D-1+ Highest certainty of timely payment. Short-term liquidity, including
         internal operating factors and/or access to alternative sources of
         funds, is outstanding and safety is just below risk-free U.S. Treasury
         obligations.
 
     D-1 Very high certainty of timely payment. Liquidity factors are excellent
         and supported by good fundamental protection factors. Risk factors are
         minor.
 
   D-1- High certainty of timely payment. Liquidity factors are strong and
        supported by good fundamental protection factors. Risk factors are very
        small.
 
STANDARD & POOR'S CORPORATION ("S&P")
 
     A-1 Highest category of commercial paper. Capacity to meet financial
         commitment is strong. Obligations designated with a plus sign (+)
         indicate that capacity to meet financial commitment is extremely
         strong.
 
     A-2 Issues somewhat more susceptible to adverse effects of changes in
         circumstances and economic conditions than obligations in higher rating
         categories. However, the capacity to meet financial commitments is
         satisfactory.
 
FITCH'S INVESTORS SERVICE, L.P. ("FITCH")
 
    F-1+ Exceptionally strong credit quality. Strongest degree of assurance for
         timely payment.
 
     F-1 Very strong credit quality. Assurance of timely payment is only
         slightly less in degree than issues rated F-1+.
 
     F-2 Good credit quality. Satisfactory degree of assurance for timely
         payment, but the margin of safety is not as good as for issues assigned
         F-1+ and F-1 ratings.
 
IBCA LIMITED ("IBCA")
 
      A1 Highest capacity for timely repayment. Those issues rated A1+ possess a
         particularly strong credit feature.
 
      A2 Satisfactory capacity for timely repayment although such capacity may
         be susceptible to adverse changes in business, economic or financial
         conditions.
 
MOODY'S INVESTORS SERVICE ("MOODY'S")
 
 PRIME-1 Superior ability for repayment.
 
 PRIME-2 Strong ability for repayment.
 
DESCRIPTION OF BANK RATINGS
 
MOODY'S
 
These ratings represent Moody's opinion of a bank's intrinsic safety and
soundness.
 
       A These banks possess exceptional intrinsic financial strength. Typically
         they will be major financial institutions with highly valuable and
         defensible business franchises, strong financial fundamentals, and a
         very attractive and stable operating environment.
 
       B These banks possess strong intrinsic financial strength. Typically,
         they will be important institutions with valuable and defensible
         business franchises, good financial fundamentals, and an attractive and
         stable operating environment.
 
       C These banks possess good intrinsic financial strength. Typically, they
         will be institutions with valuable and defensible business franchises.
         These banks will demonstrate either acceptable financial fundamentals
         within a stable operating environment, or better than average financial
         fundamentals within an unstable operating environment.

S&P
 
S&P's credit rating is a current opinion of an obligor's overall financial
capacity (its creditworthiness) to pay its financial obligation.
 
    AAA The highest rating assigned by S&P. The obligor's capacity to meet its
        financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A The obligation is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than obligations in
         higher rated categories. However, the obligor's capacity to meet its
         financial commitment on the obligation is still strong.
 
DESCRIPTION OF INSURANCE RATINGS
 
MOODY'S
 
These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.
 
    Aaa Insurance companies rated in this category offer exceptional financial
        security. While the financial strength of these companies is likely to
        change, such changes as can be visualized are most unlikely to impair
        their fundamentally strong position.
 
      Aa These insurance companies offer excellent financial security. Together
         with the Aaa group, they constitute what are generally known as high
         grade companies. They are rated lower than Aaa companies because
         long-term risks appear somewhat larger.
 
       A Insurance companies rated in this category offer good financial
         security. However, elements may be present which suggest a
         susceptibility to impairment sometime in the future.
 
S&P
 
S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.
 
    AAA This is the highest rating assigned by S&P. The obligor's capacity to
        meet its financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A An obligation rated A is somewhat more susceptible to the adverse
         effects of changes in circumstances and economic conditions than
         obligations in higher rated categories. However, the obligor's capacity
         to meet its financial commitment on the obligation is still strong.
 
DESCRIPTION OF MUNICIPAL BOND RATINGS
(including foreign, mortgage and asset-backed securities)
 
S&P
 
Investment Grade
 
    AAA The highest rating. The rating indicates an extremely strong capacity to
        meet its financial commitment.
 
     AA Differs from AAA issues only in a small degree. The obligor's capacity
        to meet its financial commitment is very strong.
 
       A These bonds are somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than debt in higher
         rated categories. However, capacity to meet its financial commitment on
         the obligation is still strong.
 
    BBB Exhibits adequate protection parameters. However, adverse economic
        conditions or changing circumstances are more likely to lead to a
        weakened capacity to meet its financial commitment on the obligations.
 
Speculative Grade
 
     BB Less vulnerable to non-payment than other speculative issues. However,
        these bonds face major ongoing uncertainties or exposure to adverse
        business, financial or economic conditions which could lead to
        inadequate capacity to meet financial commitment on the obligations.
 
       B More vulnerable to non-payment than obligations rated BB, but currently
         has the capacity to meet its financial commitment on the obligation.
         Adverse business, financial or economic conditions will likely impair
         capacity or willingness to meet its financial commitment on the
         obligation.
 
    CCC Currently vulnerable to non-payment, and is dependent upon favorable
        business, financial, and economic conditions to meet its financial
        commitment on the
<PAGE>   144
 
                                                                              41
 
        obligation. In the event of adverse business, financial, or economic
        conditions, they are not likely to have the capacity to meet its
        financial commitment on the obligation.
 
      CC Currently highly vulnerable to non-payment.
 
       C This rating may be used to cover a situation where a bankruptcy
         petition has been filed, or similar action has been taken, but payments
         on this obligation are being continued.
 
       D Bonds in payment default.
 
Ratings from AA to CCC may be modified by a plus (+) or minus (-) to show
relative standing within the major rating categories.
 
MOODY'S
 
Investment Grade
 
    Aaa Best quality. They carry the smallest degree of investment risk and are
        generally referred to as "gilt edged." Interest payments are protected
        by a large, or an exceptionally stable, margin and principal is secure.
 
      Aa High quality by all standards. Margins of protection may not be as
         large as in Aaa securities, fluctuation of protective elements may be
         greater, or there may be other elements present that make the long-term
         risks appear somewhat larger than in Aaa securities.
 
       A These bonds possess many favorable investment attributes and are to be
         considered as upper-medium grade obligations. Factors giving security
         to principal and interest are considered adequate, but elements may be
         present which suggest a susceptibility to impairment sometime in the
         future.
 
    Baa These bonds are considered medium-grade obligations (i.e., they are
        neither highly protected nor poorly secured). Interest payments and
        principal security appear adequate for the present but certain
        protective elements may be lacking or may be characteristically
        unreliable over any great length of time. Such bonds lack outstanding
        investment characteristics and in fact have speculative characteristics
        as well.
 
Non-Investment Grade
 
      Ba These bonds have speculative elements; their future cannot be
         considered as well assured. The protection of interest and principal
         payments may be very moderate and thereby not well safeguarded during
         good and bad times over the future.
 
       B These bonds lack the characteristics of a desirable investment (i.e.,
         potentially low assurance of timely interest and principal payments or
         maintenance of other contract terms over any long period of time may be
         small).
 
     Caa Bonds in this category have poor standing and may be in default. These
         bonds carry an element of danger with respect to principal and interest
         payments.
 
      Ca Speculative to a high degree and could be in default or have other
         marked shortcomings. Ca is the lowest rating.
 
DESCRIPTION OF MUNICIPAL NOTE RATINGS
 
MOODY'S
  MIG1 & Short-term municipal securities rated MIG1 or VMIG1 are of the best
   VMIG1 quality. They have strong protection from established cash flows,
         superior liquidity support or demonstrated broad-based access to the
         market for refinancing.
   

  
  MIG2 & These Short-term municipal securities are of high quality. Margins of
   VMIG2 protection are ample although not so large as in the preceding group.


  MIG3 & Favorable quality. All security elements are accounted for, but the
   VMIG3 undeniable strength of the preceding grades is lacking. Liquidity and
         cash flow protection may be narrow and marketing access for
         refinancing is likely to be less well established.














 
S&P
 
An S&P note rating reflects the liquidity concerns and market access risks
unique to notes. Notes due in three years or less will likely receive a note
rating. Notes maturing beyond three years will most likely receive a long-term
debt rating.
 
    SP-1 Strong capacity to pay principal and interest. Those issues determined
         to possess overwhelming safety characteristics will be given a plus (+)
         designation.
 
    SP-2 Satisfactory capacity to pay principal and interest.
 
    SP-3 Speculative capacity to pay principal and interest.

DESCRIPTION OF PREFERRED STOCK RATINGS
 
MOODY'S
 
     aaa Top-quality preferred stock. This rating indicates good asset
         protection and the least risk of dividend impairment within the
         universe of preferred stocks.
 
      aa High-grade preferred stock. This rating indicates that there is a
         reasonable assurance the earnings and asset protection will remain
         relatively well maintained in the foreseeable future.
 
       a Upper-medium grade preferred stock. While risks are judged to be
         somewhat greater than in the "aaa" and "aa" classification, earnings
         and asset protection are, nevertheless, expected to be maintained at
         adequate levels.
 
     baa Medium-grade preferred stock, neither highly protected nor poorly
         secured. Earnings and asset protection appear adequate at present but
         may be questionable over any great length of time.
 
S&P
 
S&P's preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations.
 
    AAA Highest rating. This rating indicates an extremely strong capacity to
        pay the preferred stock obligations.
 
     AA High-quality, fixed-income security. The capacity to pay preferred stock
        obligations is very strong, although not as overwhelming as for issues
        rated "AAA."
 
       A Backed by a sound capacity to pay the preferred stock obligations,
         although it is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions.
 
    BBB Backed by an adequate capacity to pay the preferred stock obligations.
        Whereas the issuer normally exhibits adequate protection parameters,
        adverse economic conditions or changing circumstances are more likely to
        lead to a weakened capacity to make payments for a preferred stock in
        this category than for issues in the "A" category.
 
SHORT-TERM DEBT RATINGS
 
Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.
 
  TBW-1 Very high degree of likelihood that principal and interest will be paid
        on a timely basis.
 
  TBW-2 While degree of safety regarding timely repayment of principal and
        interest is strong, the relative degree is not as high as for issues
        rated TBW-1.
 
  TBW-3 Lowest investment grade category. While more susceptible to adverse
        developments than obligations with higher ratings, capacity to service
        principal and interest in a timely fashion is considered adequate.
 
  TBW-4 Non-investment grade and, therefore, speculative.

                        A BRIEF PREVIEW OF THE FUNDS
 
             WHAT ARE THE GOALS OF THE ONE GROUP MONEY MARKET FUNDS?
             The Funds are designed for a variety of investment objectives,
             including current income, interest income exempt from Federal
             Income Tax, and interest income exempt from Federal Income Tax
             and Ohio Personal Income Tax. Each Fund pursues a different
             objective and involves different risks. All of the Funds will
             use their best efforts to maintain a constant net asset value
             of $1.00 per share, although there is no guarantee that the
             Funds will be able to do so. Please read about each Fund
             before investing.
 
             WHAT ARE THE FUNDS' INVESTMENT STRATEGIES?
             The Funds will invest only in U.S. dollar-denominated
             securities, will maintain an average maturity on a dollar-
             weighted basis of 90 days or less, and will acquire only
             "eligible securities" that present minimal credit risks and
             have a maturity of 397 days or less. The Funds intend to
             comply with Rule 2a-7 under the Investment Company Act of
             1940.
 
             WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUNDS?

             The Funds invest in securities that are backed by "credit
             enhancements" such as letters of credit. The value of
             investments in the Funds could decrease if the credit quality
             of the credit enhancement provider declines. The Prime Money
             Market Fund invests in mortgage-related securities which have
             significantly greater price and yield volatility than
             traditional fixed income securities. In addition, the Prime
             Money Market Fund invests in U.S. dollar denominated foreign
             securities which may expose the Fund to risks that are
             different from investments in U.S. Securities. The Ohio
             Municipal Money Market Fund is a nondiversified fund which
             exposes investors to special risks. For more information about
             risks, please read "More About the Funds" and "Investment
             Risks."
 
             WHAT CLASSES OF SHARES ARE AVAILABLE?
             Each Fund currently offers Class A, Class C and Fiduciary
             Class shares. Class A and Class C shares are offered to the
             general public. Fiduciary Class shares are offered to
             institutional investors, including affiliates of BANC ONE
             CORPORATION and any bank, depository institution, insurance
             company, pension plan or other organization authorized to act
             in fiduciary, advisory, agency, custodial or similar
             capacities. Fiduciary Class shares are not available to
             Individual Retirement Accounts ("IRA").
 
             The Prime Money Market Fund and the U.S. Treasury Securities
             Money Market Fund also offer Class B and Service Class shares.
             Class B shares are offered to the general public. Service
             Class shares are offered to entities purchasing such shares on
             behalf of investors requiring additional administrative or
             accounting services such as sweep processing. The section
             called "How To Do Business With The One Group" will provide
             more information.
 
             HOW DO I PURCHASE AND REDEEM SHARES?
   
             You may buy and redeem shares of the Funds on any day that the
             Funds are open for business. Class C Shares are not available
             for purchase in all of the Funds. Purchase and redemption
             procedures are explained in greater detail in "How To Do
             Business With The One Group." For additional information, call
             The One Group Services Company at 1-800-480-4111.
    
 
             HOW ARE DIVIDENDS PAID?
             Generally, dividends are declared on each business day and are
             distributed periodically. Any capital gains are distributed at
             least annually. Distributions are paid in additional shares of
             the same class unless you elect to take the payment in cash.
             For a more detailed discussion of dividends, see "Dividend
             Policies."
 
             WHO MANAGES THE FUNDS?
             Banc One Investment Advisors Corporation ("Banc One Investment
             Advisors"), an indirect subsidiary of BANC ONE CORPORATION,
             serves as the advisor of the Funds. Banc One Investment
             Advisors is paid a fee for its services. A more detailed
             discussion regarding Banc One Investment Advisors, its
             services and compensation can be found in the Prospectus under

THE ONE GROUP(R)
PRIME MONEY MARKET FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a diversified money market fund that seeks current income with
liquidity and stability of principal.
 
[ICON] PORTFOLIO SECURITIES
The Fund invests exclusively in high quality money market instruments. These
instruments include U.S. Treasury obligations, obligations issued or guaranteed
by U.S. agencies or instrumentalities, mortgage-backed securities, commercial
paper, bank obligations and deposit notes. The Fund also may invest in
commercial paper issued by foreign issuers. The Fund may invest up to 10% of its
net assets in illiquid investments such as certain restricted securities and
private placements. The Fund also engages in securities lending. For a list of
all of the securities in which the Fund may invest, please read "Investment
Policies."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in securities that are backed by "credit enhancements" such as
letters of credit. The value of your investment in the Fund could decrease if
the value of the securities in the portfolio decreases in response to declining
credit quality of a credit enhancement provider. The fund also invests in U.S.
dollar denominated foreign investments which involve risks that are different
from investments in U.S. companies. In addition, the Fund invests in
mortgage-related securities which have significantly greater price and yield
volatility than traditional fixed-income securities. Before you invest, please
read "More About the Funds" and "Investment Risks."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Expense information has been restated to reflect current fees.
(3) Without a fee waiver, Investment Advisory Fees would be .35% for all classes
    of shares.
(4) Due to 12b-1 fees, long-term Class A, Class B, Class C and Service Class
    shareholders may pay more than the equivalent of the maximum front-end sales
    charges permitted under the rules of the National Association of Securities
    Dealers. Without the voluntary waiver of fees, 12b-1 fees would be .75% for
    Service Class shares.
(5) Without a voluntary reduction of Investment Advisory and 12b-1 fees, Total
    Operating Expenses would be .80% for Class A shares, 1.55% for Class B
    shares, 1.55% for Class C shares, 1.30% for Service Class shares and .55%
    for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

</TABLE>
 
Class B shares automatically convert to Class A shares after eight years.
Therefore, the "10 years" examples above reflect this conversion.
 
Because of the nature of the shares, shareholders are not expected to remain in
Service Class shares for more than a very limited period of time. However, a
shareholder investing in the Service Class shares on a continual basis for a
period of one month would pay $1, three months would pay $3, one year would pay
$11. Without the voluntary fee reduction, that shareholder would pay $1 after
one month, $3 after three months, and $13 after one year.
 
These examples are designed to assist you in understanding the various costs and
expenses that may be directly or indirectly paid by investors in the Fund. THESE
EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES
AND ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

THE ONE GROUP(R)
MUNICIPAL MONEY MARKET FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a diversified fund that seeks as high a level of current interest
income exempt from Federal income tax as is consistent with capital preservation
and stability of principal.
 
[ICON] PORTFOLIO SECURITIES
As a matter of fundamental policy, the Fund will invest at least 80% of its
total assets in municipal securities. These are securities issued by or on
behalf of the states, territories and possessions of the United States,
including the District of Columbia, and their political subdivisions, agencies,
instrumentalities and authorities. These municipal securities produce interest
that, in the opinion of bond counsel for the issuer, is exempt from Federal
income tax. However, the Fund may invest as much as 100% of its assets in
municipal securities that produce income that is subject to the Federal
alternative minimum tax. If you are subject to the Federal alternative minimum
tax, please read the section of this prospectus entitled "Tax Treatment of
Shareholders" before you invest. The Fund also may invest up to 20% of its total
assets in other types of securities, such as taxable money market instruments,
including repurchase agreements. For a list of all the securities in which the
Fund may invest, please read "Investment Practices."
 
[ICON] RISK CONSIDERATIONS
The Fund invests in securities that are backed by "credit enhancements" such as
letters of credit. The value of your investment in the Fund could decrease if
the value of the securities in the portfolio decreases in response to declining
credit quality of a credit enhancement provider. In addition, the Fund invests
in mortgage-related securities which have significantly greater price and yield
volatility than traditional fixed-income securities. Before you invest, please
read "More Information about the Funds" and "Investment Risks."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Expense information has been restated to reflect current fees.
(3) Without a fee waiver, Investment Advisory Fees would be .35% for all classes
    of shares.
(4) Due to 12b-1 fees, long-term Class A and Class C shareholders may pay more
    than the equivalent of the maximum front-end sales charges permitted under
    the rules of the National Association of Securities Dealers.
(5) Total Operating Expenses have been revised to reflect fee waivers. Without a
    voluntary reduction of Investment Advisory fees, Total Operating Expenses
    would be .85% for Class A shares, 1.60% for Class C shares and .60% for
    Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

THE ONE GROUP(R)
OHIO MUNICIPAL MONEY MARKET FUND
[ICON] INVESTMENT OBJECTIVE
The Fund is a non-diversified money market fund that seeks as high a level of
current interest income exempt from Federal income tax and Ohio personal income
tax as is consistent with capital preservation and stability of principal.
 
[ICON] PORTFOLIO SECURITIES
   
The Fund will invest at least 80% of its total assets in Ohio municipal
securities. These are securities issued by or on behalf of the State of Ohio and
its political subdivisions, agencies, instrumentalities and authorities. Ohio
municipal securities produce interest that, in the opinion of bond counsel for
the issuer, is exempt from both Federal income tax and Ohio personal income tax.
The Fund also may invest up to 20% of its total assets in non-Ohio municipal
securities, i.e., municipal securities issued by states, territories and
possessions of the United States, including the District of Columbia, other than
Ohio, as well as their political subdivisions, agencies, instrumentalities and
authorities that produce interest exempt from Federal income tax. The Fund has
the ability to invest as much as 100% of its assets in non-Ohio municipal
securities that produce income that is subject to the Federal alternative
minimum tax. If you are subject to the Federal alternative minimum tax, please
read the section of this prospectus entitled "Tax Treatment of Shareholders"
before you invest. Finally, the Fund also may invest up to 20% of its total
assets in other types of securities, such as taxable money market instruments,
including repurchase agreements. For a list of all the securities in which the
Fund may invest, please read "Investment Practices."
    
 
[ICON] RISK CONSIDERATIONS
Because of the relatively small number of issuers of Ohio municipal securities,
the Fund's performance is effected to a greater extent by the success of one or
a few issuers than is the performance of a diversified fund. In addition, the
Fund invests in mortgage-related securities which have significantly greater
price and yield volatility than traditional fixed-income securities. Before you
invest, please read "More About the Funds" and "Investment Risks."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Expense information has been restated to reflect current fees.
(3) Without a fee waiver, Investment Advisory Fees would be .30% for all classes
    of shares.
(4) Due to 12b-1 fees, long-term Class A and Class C shareholders may pay more
    than the equivalent of the maximum front-end sales charges permitted under
    the rules of the National Association of Securities Dealers.
(5) Without a fee waiver, other expenses would be .29% for all classes of
    shares.
(6) Total Operating Expenses have been revised to reflect fee waivers. Without a
    voluntary reduction of Investment Advisory and 12b-1 fees, Total Operating
    Expenses would be .84% for Class A shares, 1.59% for Class C shares and .59%
    for Fiduciary Class shares.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Expense information has been restated to reflect current fees.
(3) Without a fee waiver, Investment Advisory Fees would be .35% for all classes
    of shares.
(4) Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted under the rules of the National Association of Securities Dealers.
    Without the voluntary waiver of fees, 12b-1 fees would be .75% for Service
    Class shares.
(5) Total Operating Expenses have been revised to reflect fee waivers. Without a
    voluntary reduction of Investment Advisory and 12b-1 fees, Total Operating
    Expenses would be .81% for Class A shares, 1.56% for Class B shares, 1.56%
    for Class C shares, 1.31% for Service Class shares and .56% for Fiduciary
    Class shares.

 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charge; (2) 5% annual return; and (3)
redemption at the end of each time period.

</TABLE>

Because of the nature of the shares, shareholders are not expected to remain in
Service Class shares for more than a very limited period of time. However, a
shareholder investing in the Service Class shares on a continual basis for a
period of one month would pay $1, three months would pay $3, and one year would
pay $11. Without the voluntary fee reduction, that shareholder would pay $1
after one month, $3 after three months, and $13 after one year.

Class B shares automatically convert to Class A shares after eight (8) years.
Therefore, the "10 years" examples above reflect this conversion.

These examples are designed to assist you in understanding the various costs and
expenses that may be directly or indirectly paid by investors in the Fund. THESE
EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES
AND ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

                              MORE ABOUT THE FUNDS
 
PORTFOLIO QUALITY
- ----------------------------------------------------
 
   
Securities will be purchased by the Funds only if Banc One Investment Advisors
determine that they present minimal credit risk under guidelines adopted by the
Board of Trustees. In addition, unless a more specific rating is specified, all
investments of the Funds must be rated in one of the two highest rating
categories described in "Description of Ratings" in the Appendix. If an
investment is unrated, Banc One Investment Advisors must determine that it is of
comparable quality to a rated security. Banc One Investment Advisors will look
at a security's rating at the time of investment. For more information about
ratings, please see "Description of Ratings" in the Appendix.
    
 
ILLIQUID INVESTMENTS
- ----------------------------------------------------
 
Each Fund may invest up to 10% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by The One Group Board of Trustees in determining whether an
investment is illiquid.
 
SPECIAL RISK
CONSIDERATIONS
- ----------------------------------------------------
 
NET ASSET VALUE: There is no assurance that the Funds will meet their investment
objectives or be able to maintain a net asset value of $1.00 per share on a
continuous basis.
 
NON-DIVERSIFIED FUNDS: The Ohio Municipal Money Market Fund is a
"non-diversified" fund. This means that the Fund may invest a significantly
greater portion of its assets in the securities of a single issuer than can a
"diversified" fund. In addition, the Fund's investments are concentrated
geographically. These concentrations increase the risk of loss to the Fund if
the issuer of a security fails to make interest or principal payments or if the
market value of a security declines. Investment in the Fund may entail more
risks than an investment in another type of money market fund.
 
   
THE OHIO ECONOMY: The Ohio Municipal Money Market Fund's investments are
concentrated in the State of Ohio. While Ohio's economy has become increasingly
diversified, it continues to rely to a significant degree on durable goods
manufacturing, such as automobiles, tires, steel and household appliances. These
industries tend to be cyclical. Agriculture also is an important part of the
Ohio economy, and the state has several programs that provide financial
assistance to farmers. Although obligations issued by the state and its
political subdivisions are payable from specific sources or taxes, future
economic difficulties and the impact on state and local government finances may
negatively affect the market value of the Ohio municipal securities held by the
Ohio Municipal Money Market Fund.
    
 
   
FIXED INCOME SECURITIES: Investments in fixed income securities (for example,
bonds) will increase or decrease in value based on changes in interest rates. If
rates increase, the value of a Fund's investments generally declines. On the
other hand, if rates fall, the value of the investments generally increases. The
value of your investment in a Fund will increase and decrease as the value of a
Fund's investments increase and decrease. While securities with longer duration
and maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment.
    
 
DERIVATIVES: Some of the Funds invest in securities that are considered to be
derivatives. These securities may be more volatile than other securities. These
include mortgage-backed securities, including collateralized mortgage
obligations and Real Estate Mortgage Investment Conduits (CMOs and REMICs) and
asset-backed securities. Derivatives may be riskier than traditional
investments.

                     HOW TO DO BUSINESS WITH THE ONE GROUP
PURCHASING
FUND SHARES
- ----------------------------------------------------
 
WHERE CAN I BUY SHARES?
 
You may purchase Fund shares from the following sources:
 
- - The One Group Services Company, and
 
- - Shareholder Servicing Agents. These include investment advisors, brokers,
  financial planners, banks, insurance companies, retirement or 401(k) plan
  sponsors, or other intermediaries. Shares purchased this way will be held for
  you by the Shareholder Servicing Agent.
 
WHEN CAN I BUY SHARES?
 
- - Purchases may be made on any business day. This includes any day that the
  Funds are open for business, other than weekends and the following holidays:
  New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
  Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day,
  Thanksgiving, and Christmas.
 
- - Purchase requests will be effective on the day received by The One Group
  Services Company and you will be eligible to receive dividends declared the
  same day, if such purchase orders are received by The One Group Services
  Company:
 
     (i) before 11:00 a.m., Eastern Standard Time ("EST"), for the Ohio
         Municipal Money Market Fund;
 
     (ii) before 12:00 noon, EST, for the Municipal Money Market Fund; and
 
     (ii) before 2:00 p.m., EST, for the Prime Money Market Fund and the U.S.
          Treasury Securities Money Market Fund.
 
   In addition, the Fund's custodian, State Street Bank and Trust Company, must
   receive "federal funds" before 4:00 p.m., EST on such day. If State Street
   Bank and Trust Company does not receive federal funds by the cut-off time,
   the purchase order will not be effective until the next business day on which
   federal funds are timely received by State Street Bank and Trust Company.
 
- - If your shares are held by a Shareholder Servicing Agent, it is the
  responsibility of the Shareholder Servicing Agent to send your purchase or
  redemption order to the Fund. Your Shareholder Servicing Agent may have an
  earlier cut-off time for purchase and redemption requests.
 
- - The One Group Services Company can reject a purchase order if it does not
  think that it is in the best interests of a Fund and/or its shareholders to
  accept the order.
 
- - Shares are electronically recorded. Therefore, certificates will not be
  issued.
 
WHAT KIND OF SHARES CAN I BUY?
 
The One Group offers the following classes of shares:
 
- - Class A, Class B and Class C shares are available to the general public.
 
- - Fiduciary Class shares are available to institutional investors and any
  organization authorized to act in a fiduciary, advisory, custodial or agency
  capacity. We will refer to these entities as "Intermediaries."
 
- - Service Class shares are available to Intermediaries purchasing shares on
  behalf of investors requiring additional administrative or accounting services
  such as sweep processing.
 
- - If you intend to hold your shares six or more years, Class B shares may be
  appropriate for you. If you intend to hold your shares for less than six
  years, you may want to consider Class A or Class C shares.
 
   
The One Group Fund Direct IRA. The One Group offers a retirement plan and, in
1998, will offer an education plan. These plans allow participants to defer
taxes while their retirement and education savings grow. The education IRA
requires a minimum investment of $500. Call The One Group Services Company at
1-800-480-4111 for an Adoption Agreement.
    
 
HOW MUCH DO SHARES COST?
 
- - Shares are sold at net asset value ("NAV").
 
- - NAV per share is calculated by dividing the total market value of a Fund's
  investment and other assets allocable to a class (minus class expenses) by the
  number of outstanding shares in that class. The Funds use their best efforts
  to maintain their NAV at $1.00, although there is no guarantee that they will
  be able to do so.
 
- - NAV is calculated each business day as of 11:00 a.m. and 4:00 p.m., EST, for
  the Ohio Municipal Money Market Fund, as of 12:00 noon and 4:00 p.m., EST, for
  the Municipal Money Market Fund, and as of 2:00 p.m. and 4:00 p.m., EST, for
  the Prime Money Market Fund and the U.S. Treasury Securities Money Market
  Fund.

   - The One Group Services Company may waive these minimums.
 
3.Complete the Account Application Form. Be sure to sign up for all of the
  Account privileges that you plan to take advantage of. Doing so now means that

  dividends until the check clears.

SALES CHARGES
- ----------------------------------------------------
 
   
The One Group Services Company compensates Shareholder Servicing Agents who sell
shares of The One Group. Compensation comes from: sales charges, 12b-1 fees and
payments by The One Group Services Company from its own resources. The One Group
Services Company, at its own expense, also will provide promotional incentives
in the form of travel expenses, lodging and bonuses to licensed individuals who
sell shares of the Funds, as well as vacation trips (including lodging at luxury
resorts), tickets to entertainment events, and merchandise.
    
 
 CLASS B SHARES.
 
Class B shares are offered at NAV, without any up-front sales charges. However,
if you redeem these shares within six years of the purchase date, you will be
assessed a Contingent Deferred Sales Charge ("CDSC") according to the following
schedule:
 
<TABLE>
<CAPTION>
                          CDSC AS A % OF DOLLAR
YEARS SINCE PURCHASE     AMOUNT SUBJECT TO CHARGE
<S>                      <C>                      <C>
         0-1                       5.00%
         1-2                       4.00%
         2-3                       3.00%
         3-4                       3.00%
         4-5                       2.00%
         5-6                       1.00%
     more than 6                   0.00%
</TABLE>
 
The One Group Services Company pays a commission of 4.00% of the original
purchase price to Shareholder Servicing Agents who sell Class B shares.
 
 CLASS C SHARES
 
Class C shares are offered at NAV, without any up-front sales charge. However,
if you redeem your shares within one year of the purchase date, you will be
assessed a CDSC as follows:
 
<TABLE>
<CAPTION>
                          CDSC AS A % OF DOLLAR
YEARS SINCE PURCHASE     AMOUNT SUBJECT TO CHARGE
<S>                      <C>                      <C>
         0-1                       1.00%
  After first year                  none
</TABLE>
 
The One Group Services Company pays a commission of 1.00% of the original
purchase price to Shareholder Servicing Agents who sell Class C shares.
 
How the CDSC is Calculated
 
- - The Fund assumes that all purchases made in a given month were made on the
  first day of the month.
 
- - The CDSC is based on the net amount redeemed.
 
- - A sales charge is not assessed on shares acquired through reinvestment of
  dividends or capital gains distributions.
 
- - To keep your CDSC as low as possible, the Fund first will redeem any shares in
  your account that carry no CDSC, starting with Class A Shares. After that, the
  Fund will redeem the shares you have held for the longest time and thus have
  the lowest CDSC.
<PAGE>   164

12B-1 FEES.
 
12b-1 fees are paid by The One Group to The One Group Services Company as
compensation for its services and expenses. The One Group Services Company in
turn pays all or part of the 12b-1 fee to brokers and other Shareholder
Servicing Agents that sell shares of The One Group.
 
- - The 12b-1 fees vary by share class as follows:
 
   1. Class A shares pay a 12b-1 fee of .25% of the average daily net assets of
      the Fund.
 
   2. Class B and Class C shares pay a 12b-1 fee of 1.00% of the average daily
      net assets of the Fund. This will cause expenses for Class B and Class C
      shares to be higher and dividends to be lower than for Class A shares.
 
   3. Service Class shares pay a 12b-1 fee of .75% of the average daily net
      assets of the Fund, which is currently being waived to .55%.
 
   4. There are no 12b-1 fees for Fiduciary Class shares.
 
- - 12b-1 fees, together with the CDSC, help The One Group Services Company sell
  Class B and Class C shares without an "up-front" sales charge by defraying the
  costs of advancing brokerage commissions and other expenses paid to
  Shareholder Servicing Agents.
 
- - The One Group Services Company may use up to .25% of the fees for shareholder
  servicing and up to .75% for distribution. During the last fiscal year, The
  One Group Services Company received 12b-1 fees totaling .25% and 1.00% of the
  average daily net assets of Class A and Class B shares, respectively.
 
- - The One Group Services Company may pay 12b-1 fees to its affiliates and to
  Banc One Investment Advisors and its affiliates (or any sub-advisor) for
  brokerage and other agency transactions.

  Fund of The One Group, but only if you are eligible to purchase those shares.
 
- - Class B shares of a Fund may be exchanged for Class B shares of another Fund
  of The One Group.
 
- - Class C shares of a Fund may be exchanged for Class C shares of another Fund
  of The One Group.
 
- - Service Class shares do not have exchange privileges.
 
The One Group may change the terms and conditions of your exchange privileges
upon 60 days written notice.
 
The One Group does not charge a fee for this privilege.
 
WHEN ARE EXCHANGES PROCESSED?
 
Exchanges are processed the same business day they are received, provided:
 
- - State Street Bank and Trust Company receives the request by:
 
      (i) 11:00 a.m. EST, for the Ohio Municipal Money Market Fund,
 
      (ii) 12:00 noon EST, for the Municipal Money Market Fund, and
 
     (iii) 2:00 p.m. EST, for the Prime Money Market Fund and the U.S. Treasury
           Securities Money Market Fund.
 
- - You have provided The One Group with all of the information necessary to
  process the exchange.
 
- - You have received a current prospectus of the Fund or Funds into which you
  wish to invest.
 
- - You have contacted your Shareholder Servicing Agent, if necessary.
 
DO I PAY A SALES CHARGE ON AN EXCHANGE?
 
Generally, you will not pay a sales charge on an exchange. However:
 
- - You will pay a sales charge if you own Fiduciary Class shares of a Fund and
  you want to exchange those shares for Class A shares, unless you qualify for a
  sales charge waiver (see above).
 
- - You will pay a sales charge if you bought Class A shares of a Fund:
 
   1. That does not charge a sales charge and you want to exchange them for
      shares of a Fund that does, in which case you would pay the sales charge
      applicable to the Fund into which you are exchanging.
 
   2. That charged a lower sales charge than the Fund into which you are
      exchanging, in which case you would pay the difference between that Fund's
      sales charge and all other sales charges you have already paid.
 
- - If you exchange Class B or Class C shares of a Fund, you will not pay a sales
  charge at the time of the exchange, however:
 
   1. Your new Class B or Class C shares will be subject to the higher CDSC of
      either the Fund from which you exchanged, the Fund into which you
      exchanged, or any Fund from which you previously exchanged.
 
   2. The current holding period for your exchanged Class B or Class C shares is
      carried over to your new shares.
 
ARE EXCHANGES TAXABLE?
 
Generally:
 
- - An exchange between classes of shares of the same Fund is not taxable.
 
- - An exchange between Funds is considered a sale and generally results in a
  capital gain or loss for Federal income tax purposes.
 
- - You should talk to your tax advisor before making an exchange.
 
ARE THERE LIMITS ON EXCHANGES?
 
Yes. The exchange privilege is not intended as a way for you to speculate on
short-term movements in the market. Therefore:
 
- - To prevent disruptions in the management of the Funds, The One Group limits
  excessive exchange activity.
 
- - Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
  REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH PERIOD.
 
   
- - In addition, The One Group reserves the right to reject any exchange request
  (even those that are not excessive) if the Fund reasonably believes that the
  exchange will result in excessive transaction costs or otherwise adversely
  affect other shareholders.

- - State Street Bank and Trust Company may require that the signature on your
  redemption request be guaranteed by a commercial bank, a member of a domestic
  stock exchange, or a member of the Securities Transfer Association Medallion
  Program or the Stock Exchange Medallion Program, unless:
 
   1. the redemption is for $50,000 worth of shares or less;
 
   2. the redemption is payable to the shareholder of record; and
 
   3. the redemption check is mailed to the shareholder at the record address.
 
- - On the Account Application Form you may elect to have the redemption proceeds
  mailed or wired to:
 
   
   1. a designated commercial bank; or
    
 
   2. State Street Bank and Trust Company or your Shareholder Servicing Agent.
 
   
- - State Street Bank and Trust Company may charge you a wire redemption fee. The
  current charge is $7.00.
    
 
- - Your redemption proceeds will ordinarily be paid within seven days after
  receipt of the redemption request. However, the Funds will attempt to honor
  requests for next day payment on redemptions, if the request is received
  before:
 
      (i)11:00 a.m. EST, for the Ohio Municipal Money Market Fund,

      (ii)12:00 noon EST, for the Municipal Money Market Fund, and

     (iii)2:00 p.m. EST, for the Prime Money Market Fund and the U.S. Treasury
          Securities Money Market Fund.
 
- - The Funds also will attempt to honor requests for payments in two business
  days, if the redemption request is received after the times listed above.
 
WHAT WILL MY SHARES BE WORTH?
 
- - The NAV of shares of the Funds are expected to remain constant at $1.00 per
  share, although there is no assurance that this will always be the case.
 
- - If you own Class A, Service Class or Fiduciary Class shares, you will receive
  the NAV calculated after your redemption request is received. Please read "How
  Much Do Shares Cost?"
 
- - If you own Class B or Class C shares, you will receive the NAV calculated
  after your redemption request is received, minus the amount of any applicable
  CDSC.
 
CAN I REDEEM BY TELEPHONE?
 
Yes, if you selected this option on your Account Application Form.
 
- - Call your Shareholder Servicing Agent or State Street Bank and Trust Company
  at 1-800-480-4111 to relay your redemption request.
 
- - Your redemption proceeds will be mailed or wired to the commercial bank
  account you designated on your Account Application Form.
 
- - State Street Bank and Trust Company may charge you a wire redemption fee. The
  current charge is $7.00.
 
- - The One Group uses reasonable procedures to confirm that instructions given by
  telephone are genuine. These procedures include recording telephone
  instructions and asking for personal identification. If these procedures are
  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
- - REDEMPTIONS FROM YOUR IRA ACCOUNT MAY NOT BE MADE BY TELEPHONE.
 
CAN I REDEEM ON A SYSTEMATIC BASIS?
 
If you have an account value of at least $10,000 you may elect to receive
monthly, quarterly or annual payments of not less than $100 each.
 
- - Select the "Systematic Withdrawal Plan" option on the Account Application
  Form.
 
- - Specify the amount you wish to receive and the frequency of the payments.
 
- - You may designate a person other than yourself as the payee.
 
- - There is no charge for this service.
 
- - If you select this option, please keep in mind that:
 
   1. If you own Class B or Class C shares, you or your designated payee may
      receive systematic payments provided the payments are limited to no more
      than 10% of your account value annually, measured from the date the
      redemption request is received.
 
   2. If you are age 70 1/2, you may elect to receive payments to the extent
      that the payment represents a minimum required distribution from an IRA or
      other qualifying retirement plan. You also may elect to receive payments
      of less than $100 each.
 
   3. If the amount of the systematic payment exceeds the income earned by your
      account since the previous payment under the Systematic Withdrawal Plan,
      payments will be made by redeeming some of your shares. This will reduce
      the amount of your investment.

ADDITIONAL INFORMATION REGARDING REDEMPTIONS
 
- - All redemptions will be for cash. The redemption price of shares is expected
  to remain constant at $1.00 per share, although there is no assurance that
  this will always be the case.
 
- - If you redeem shares for which you paid by check, and The One Group has not
  yet received payment on the check, The One Group will delay forwarding your
  redemption proceeds for 10 or more days until payment has been collected from
  your bank.
 
- - Because of the high cost of handling small investments, The One Group will
  automatically redeem shares in accounts which, because of shareholder
  redemptions, have values of less than $1,000. No sales charges will be
  assessed and you will be given 60 days to make additional investments in the
  Fund to increase the value of your account to at least $1,000.
 
- - The One Group may suspend your ability to redeem, or will redeem your shares
  involuntarily, when it seems appropriate to do so in light of its
  responsibilities under the Federal securities laws. The Statement of
  Additional Information offers more details about this process.

VOTING RIGHTS
- ----------------------------------------------------
 
The Funds do not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change a Fund's fundamental investment objective, or approve an
investment advisory contract.
 
As a Fund shareholder, you have one vote for each share that you own. Each Fund,
and each class of shares within each Fund, vote separately on matters relating
solely to that Fund or class, or which affect that Fund or class differently.
However, all shareholders will have equal voting rights on matters that affect
all shareholders equally.

BANC ONE CORPORATION (100 East Broad Street, Columbus, Ohio, 43271), through its
affiliates, may be deemed for purposes of The Investment Company Act of 1940, to
control the Prime Money Market Fund, the Ohio Municipal Money Market Fund and
the Municipal Money Market Fund. This is because as of August 5, 1997, BANC ONE
CORPORATION or its affiliates possessed the power to vote substantially all of
the Fiduciary Class shares of the Funds. On the same date, the following
shareholders owned 25% or more of Class A and Class B shares of the Funds. As a
consequence, they are considered to be controlling persons of those classes of
the Funds.

DIVIDEND POLICIES
- ----------------------------------------------------
 
DIVIDENDS
 
The Funds generally declare dividends on each business day. Dividends are
distributed on the first business day of each month. Capital gains, if any, for
all Funds are distributed at least annually.
 
   
Dividends payable on Fiduciary Class shares will be more than those payable on
other classes of shares. This is because Class A, Class B, Class C and Service
Class shares have higher distribution expenses.
    
 
DIVIDEND REINVESTMENT
 
You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund and class, unless you have
elected to take such payment in cash. The price of the shares is the NAV
determined immediately following the dividend record date. Reinvested dividends
and distributions receive the same tax treatment as dividends and distributions
paid in cash.
 
If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8500, Boston, MA
02266-8500, at least 15 days prior to the distribution. The change is effective
upon receipt by State Street.
 
SPECIAL DIVIDEND RULES FOR CLASS B SHARES
 
Class B shares received as dividends and capital gains distributions will be
accounted for separately. Each time any Class B shares (other than those in the
sub-account) convert to Class A shares, a percentage of the Class B shares in
the sub-account will also convert to Class A shares. (See "Conversion Feature.")

TAX TREATMENT
OF THE FUNDS
- ----------------------------------------------------
 
TAX STATUS OF THE FUND
 
Each Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Funds qualify, as they have in the past, they will
pay no federal income tax on the earnings they distribute to shareholders.
 
TAX TREATMENT
OF SHAREHOLDERS
- ----------------------------------------------------
 
TAXATION OF SHAREHOLDER TRANSACTIONS
 
A sale, exchange, or redemption of Fund shares will generally produce either a
taxable gain or a loss. You are responsible for any tax liabilities generated by
your transactions.
 
TAXATION OF DISTRIBUTIONS -- PRIME MONEY MARKET FUND AND U.S. TREASURY
SECURITIES MONEY MARKET FUND
 
Each Fund will distribute substantially all of its net investment income
(including, for this purpose, net short-term capital gain) to investors on at
least an annual basis. Dividends you receive from a Fund, whether reinvested or
received in cash, will be taxable to you. Dividends from a Fund's net investment
income will be taxable as ordinary income and dividends from a Fund's long-term
capital gains will be taxable to you as such, regardless of how long you have
held the shares.
 
Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid the previous December.
 
TAXATION OF DIVIDENDS -- THE OHIO MUNICIPAL MONEY MARKET FUND AND THE MUNICIPAL
MONEY MARKET FUND
 
Each Fund will distribute substantially all of its net investment income
(including, for this purpose, net short-term capital gain) to investors on at
least an annual basis. These Funds may pay "exempt-interest dividends" if at
least 50% of the value of Fund assets at the end of each quarter of the Fund's
taxable year consists of obligations the interest on which is excludable from
gross income. Exempt-interest dividends are generally excludable from an
investor's gross income for regular Federal income tax purposes. However, the
receipt of exempt-interest dividends may cause recipients of Social Security or
Railroad Retirement benefits to be taxed on a portion of such benefits. In
addition, the receipt of exempt-interest dividends may result in liability for
Federal alternative minimum tax and for state and local taxes. Corporate
shareholders will be required to take the interest on municipal securities into
account in determining their alternative minimum taxable income.
 
OHIO TAXATION OF DIVIDENDS FROM THE OHIO MUNICIPAL MONEY MARKET FUND
 
   
Dividends received from the Ohio Municipal Money Market Fund that result from
interest on Ohio municipal securities are exempt from the Ohio personal income
tax. Some Ohio statutes provide that interest on and gain from the sale of Ohio
municipal securities is exempt from all taxation in Ohio. Dividends that are
attributable to interest on or gain from the sale of obligations issued under
such statutes should be exempt from Ohio personal income tax. Ohio
municipalities may not impose income taxes on dividends on any intangible
property (including such property of the Fund) unless the intangible income was
not exempt from municipal income taxation before April 2, 1986 and the tax was
approved in an election held on November 8, 1988. Corporate shareholders will be
required to include the interest on Ohio municipal securities in their
alternative minimum-taxable income. Information in this paragraph is based on
current statutes and regulations as well as current policies of the Ohio
Department of Taxation, all of which may change.
    
 
TAXATION OF RETIREMENT PLANS
 
Distributions by the Funds to qualified retirement plans will not be taxable.
However, if shares are held by a plan that ceases to qualify for tax-exempt
treatment or by an individual who has received shares as a distribution from a
retirement plan, the distributions will be taxable to the plan or individual as
described in "Taxation of Distributions." If you are considering purchasing
shares with qualified retirement plan assets, you should consult your tax
advisor for a more complete explanation of the Federal, state, local and (if
applicable) foreign tax consequences of making such an investment.
 
TAX INFORMATION
 
The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Funds provide you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Funds or their shareholders.

INVESTMENT RISKS
- ----------------------------------------------------
 
Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities held by the Funds may fluctuate, as will the value of
your investment in the Funds. Certain investments are more susceptible to these
risks than others.
 
- - CREDIT RISK. The risk that the issuer of a security, or the counterparty to a
  contract, will default or otherwise become unable to honor a financial
  obligation. Credit risk is generally higher for non-investment grade
  securities. The price of a security can be adversely affected prior to actual
  default as its credit status deteriorates and the probability of default
  rises.
 
   
- - LEVERAGE RISK. The risk associated with securities or practices (such as
  borrowing) that multiply small index or market movements into large changes in
  value.
    
 
- - LIQUIDITY RISK. The risk that certain securities may be difficult or
  impossible to sell at the time and the price that normally prevails in the
  market. The seller may have to lower the price, sell other securities instead
  or forego an investment opportunity, any of which could have a negative effect
  on fund management or performance. This includes the risk of missing out on an
  investment opportunity because the assets necessary to take advantage of it
  are tied up in less advantageous investments.
 
- - MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
  to produce the intended result. This includes the risk that changes in the
  value of a hedging instrument will not match those of the asset being hedged.
  Incomplete matching can result in unanticipated risks.
 
- - MARKET RISK. The risk that the market value of a security may move up and
  down, sometimes rapidly and unpredictably. These fluctuations may cause a
  security to be worth less than the price originally paid for it, or less than
  it was worth at an earlier time. Market risk may affect a single issuer,
  industry, sector of the economy or the market as a whole. For fixed income
  securities, market risk is largely, but not exclusively, influenced by changes
  in interest rates. A rise in interest rates typically causes a fall in values,
  while a fall in rates typically causes a rise in values. Finally, key
  information about a security or market may be inaccurate or unavailable. This
  is particularly relevant to investments in foreign securities.
 
- - POLITICAL RISK. The risk of losses attributable to unfavorable governmental or
  political actions, seizure of foreign deposits, changes in tax or trade
  statutes, and governmental collapse and war.
 
- - FOREIGN INVESTMENT RISK. Risks associated with higher transaction costs,
  delayed settlements, currency controls, and adverse economic developments.
  This also includes the risk that fluctuations in the exchange rates between
  the U.S. dollar and foreign currencies may negatively affect an investment.
  Adverse changes in exchange rates may erode or reverse any gains produced by
  foreign currency denominated investments and may widen any losses. Exchange
  rate volatility also may affect the ability of an issuer to repay U.S. dollar
  denominated debt, thereby increasing credit risk.
 
- - PRE-PAYMENT RISK. The risk that the principal repayment of a security will
  occur at an unexpected time, especially that the repayment of a mortgage or
  asset-backed security occurs either significantly sooner or later than
  expected. Changes in pre-payment rates can result in greater price and yield
  volatility. Pre-payments generally accelerate when interest rates decline.
  When mortgage and other obligations are pre-paid, a Fund may have to reinvest
  in securities with a lower yield. Further, with early repayment, a Fund may
  fail to recoup any premium paid, resulting in an unexpected capital loss.
 
- - TAX RISK. The risk that the issuer of the securities will fail to comply with
  certain requirements of the Internal Revenue Code, which would cause adverse
  tax consequences.
 
- - REGULATORY RISK. The risk associated with Federal and state laws which may
  restrict the remedies that a mortgage lender has when a borrower defaults on
  mortgage loans. These laws include restrictions on foreclosures, redemption
  rights after foreclosure, Federal and state bankruptcy and debtor relief laws,
  restrictions on "due on sale" clauses, and state usury laws.

INVESTMENT POLICIES
- ----------------------------------------------------
 
Each Fund's investment objective and the following investment policies
summarized below are fundamental. This means that they cannot be changed without
the consent of a majority of the outstanding shares of the Funds. In addition to
the fundamental policies mentioned earlier, the following fundamental policies
apply to each Fund as specified. The full text of the fundamental policies can
be found in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES OF EACH FUND
 
Each Fund:
 
1. Will use its best efforts to maintain a constant net asset value of $1.00 per
   share, although there is no guarantee that the Funds will be able to do so.
 
2. Will not make loans, except that a Fund may (i) purchase or hold debt
   instruments in accordance with its investment objective and policies; (ii)
   enter into repurchase agreements; and (iii) engage in securities lending.
 
FUNDAMENTAL POLICIES OF SPECIFIC FUNDS
 
The Prime Money Market Fund:
 
1. Will not concentrate its investments in the securities of one or more issuers
   conducting their principal business in a particular industry or group of
   industries. This does not include obligations issued or guaranteed by the
   U.S. government or its agencies and instrumentalities, domestic bank
   certificates of deposit or bankers' acceptances, and repurchase agreements
   involving such securities, municipal securities or governmental guarantees of
   municipal securities. In addition, private activity bonds backed only by the
   revenues and assets of a non-governmental user will not be deemed to be
   municipal securities.
 
The Prime Money Market Fund, the Municipal Money Market Fund and the U.S.
Treasury Securities Money Market Fund:
 
   
1. Will not purchase an issuer's securities if as a result more than 5% of a
   Fund's total assets would be invested in the securities of that issuer or the
   Fund would own more than 10% of the outstanding voting securities of that
   issuer. This does not include securities issued or guaranteed by the United
   States, its agencies or instrumentalities, and repurchase agreements
   involving these securities. This restriction applies with respect to 75% of a
   Fund's total assets. The Funds may invest the remaining 25% of their total
   assets without restriction.
    
 
The U.S. Treasury Securities Money Market Fund:
 
1. Will invest only in U.S. Treasury obligations and repurchase agreements
   collateralized by such obligations.
 
The Ohio Municipal Money Market Fund:
 
   
1. Will not purchase an issuer's securities if as a result more than 25% of its
   total assets would be invested in the securities of that issuer or the Fund
   would own more than 10% of the outstanding voting securities of that issuer.
   This does not include securities issued or guaranteed by the United States,
   its agencies or instrumentalities, securities of registered investment
   companies, and repurchase agreements involving these securities. This
   restriction applies with respect to 50% of the Fund's total assets. With
   respect to the remaining 50% of its total assets, the Fund will not purchase
   an issuer's securities if as a result more then 5% of its total assets would
   be invested in the securities of that issuer.
    
 
2. Will not concentrate its investments in the securities of one or more issuers
   conducting their principal business in a particular industry or group of
   industries. This does not include municipal securities or governmental
   guarantees of municipal securities. In addition, private activity bonds
   backed only by the assets and revenues of a non-governmental user will not be
   deemed to be Ohio municipal securities.
 
The Municipal Money Market Fund:
 
1. Will not concentrate its investments in the securities of one or more issuers
   conducting their principal business in a particular industry or group of
   industries. This does not include municipal securities or governmental
   guarantees of municipal securities. In addition, private activity bonds
   backed only by the revenues and assets of a non-governmental user will not be
   deemed to be municipal securities.

TEMPORARY DEFENSIVE POSITION
 
Sometimes the Ohio Municipal Money Market Fund and the Municipal Money Market
Fund may temporarily invest up to 100% of their total assets in securities that
are not municipal securities, such as taxable money market instruments
(including repurchase agreements) and may hold uninvested cash pending
investment. While the Funds are engaged in a temporary defensive position, they
will not be pursuing their investment objectives. Therefore, the Funds will
pursue a temporary defensive position only when market conditions warrant.

                                    APPENDIX
DESCRIPTION OF RATINGS
 
The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.
 
Unrated securities will be treated as non-investment grade securities unless
Banc One Investment Advisors determines that such securities are the equivalent
of investment grade securities. Securities that have received different ratings
from more than one agency are considered investment grade if at least one agency
has rated the security investment grade.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS

These ratings represent Moody's opinion of a bank's intrinsic safety and
soundness.
 
       A These banks possess exceptional intrinsic financial strength. Typically
         they will be major financial institutions with highly valuable and
         defensible business franchises, strong financial fundamentals, and a
         very attractive and stable operating environment.
 
       B These banks possess strong intrinsic financial strength. Typically,
         they will be important institutions with valuable and defensible
         business franchises, good financial fundamentals, and an attractive and
         stable operating environment.
 
       C These banks possess good intrinsic financial strength. Typically, they
         will be institutions with valuable and defensible business franchises.
         These banks will demonstrate either acceptable financial fundamentals
         within a stable operating environment, or better than average financial
         fundamentals within an unstable operating environment.

S&P
S&P's credit rating is a current opinion of an obligor's overall financial
capacity (its creditworthiness) to pay its financial obligation.
 
    AAA The highest rating assigned by S&P. The obligor's capacity to meet its
        financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A The obligation is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than obligations in
         higher rated categories. However, the obligor's capacity to meet its
         financial commitment on the obligation is still strong.
 
DESCRIPTION OF INSURANCE RATINGS
 
MOODY'S
 
These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.
 
    Aaa Insurance companies rated in this category offer exceptional financial
        security. While the financial strength of these companies is likely to
        change, such changes as can be visualized are most unlikely to impair
        their fundamentally strong position.
 
      Aa These insurance companies offer excellent financial security. Together
         with the Aaa group, they constitute what are generally known as high
         grade companies. They are rated lower than Aaa companies because
         long-term risks appear somewhat larger.
 
       A Insurance companies rated in this category offer good financial
         security. However, elements may be present which suggest a
         susceptibility to impairment sometime in the future.
 
S&P
 
S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.
 
    AAA This is the highest rating assigned by S&P. The obligor's capacity to
        meet its financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A An obligation rated A is somewhat more susceptible to the adverse
         effects of changes in circumstances and economic conditions than
         obligations in higher rated categories. However, the obligor's capacity
         to meet its financial commitment on the obligation is still strong.
 
DESCRIPTION OF CORPORATE/MUNICIPAL BOND RATINGS
 
S&P
 
Investment Grade
 
    AAA The highest rating. The rating indicates an extremely strong capacity to
        meet its financial commitment.
 
     AA Differs from AAA issues only in a small degree. The obligor's capacity
        to meet its financial commitment is very strong.
 
       A These bonds are somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than debt in higher
         rated categories. However, capacity to meet its financial commitment on
         the obligations is still strong.
 
    BBB Exhibits adequate protection parameters. However, adverse economic
        conditions or changing circumstances are more likely to lead to a
        weakened capacity to meet its financial commitment on the obligations.
 
Speculative Grade
 
     BB Less vulnerable to non-payment than other speculative issues. However,
        these bonds face major ongoing uncertainties or exposure to adverse
        business, financial or economic conditions which could lead to
        inadequate capacity to meet financial commitment on the obligation.
 
       B More vulnerable to non-payment than obligations rated BB, but currently
         has the capacity to meet its financial commitment on the obligation.
         Adverse business, financial or economic conditions will likely impair
         capacity or willingness to meet its financial commitment on the
         obligation.
 
    CCC Currently vulnerable to non-payment, and is dependent upon favorable
        business, financial, and economic conditions to meet its financial
        commitment on the obligation. In the event of adverse

         business, financial, or economic conditions will likely impair the 
         capacity to meet its financial commitment on the obligation.
    
 
      CC Currently highly vulnerable to non-payment.
 
       C This rating may be used to cover a situation where a bankruptcy
         petition has been filed, or similar action has been taken, but payments
         on this obligation are being continued.
 
       D Bonds in payment default.
 
Ratings from AA to CCC may be modified by a plus (+) or minus (-) to show
relative standing within the major rating categories.
 
MOODY'S
 
Investment Grade
 
    Aaa Best quality. They carry the smallest degree of investment risk and are
        generally referred to as "gilt edged." Interest payments are protected
        by a large, or an exceptionally stable, margin and principal is secure.
 
      Aa High quality by all standards. Margins of protection may not be as
         large as in Aaa securities or fluctuation of protective elements may be
         greater, or there may be other elements present that make the long-term
         risks appear somewhat larger than in Aaa securities.
 
       A These bonds possess many favorable investment attributes and are to be
         considered as upper-medium grade obligations. Factors giving security
         to principal and interest are considered adequate, but elements may be
         present which suggest a susceptibility to impairment sometime in the
         future.
 
    Baa These bonds are considered medium-grade obligations (i.e., they are
        neither highly protected nor poorly secured). Interest payments and
        principal security appear adequate for the present but certain
        protective elements may be lacking or may be characteristically
        unreliable over any great length of time. Such bonds lack outstanding
        investment characteristics and in fact have speculative characteristics
        as well.
 
Non-Investment Grade
 
      Ba These bonds have speculative elements; their future cannot be
         considered as well assured. The protection of interest and principal
         payments may be very moderate and thereby not well safeguarded during
         good and bad times over the future.
 
       B These bonds lack the characteristics of a desirable investment (i.e.,
         potentially low assurance of timely interest and principal payments or
         maintenance of other contract terms over any long period of time may be
         small).
 
     Caa Bonds in this category have poor standing and may be in default. These
         bonds carry an element of danger with respect to principal and interest
         payments.
 
      Ca Speculative to a high degree and could be in default or have other
         marked shortcomings. Ca is the lowest rating.
 
DESCRIPTION OF MUNICIPAL NOTE RATINGS
 
MOODY'S
MIG1 &    Short-term municipal securities rated MIG1 or VMIG1 are of the best
 VMIG1    quality. They have strong protection from established cash flows,
          superior liquidity support or demonstrated broad-based access to the
          market for refinancing.

MIG2 &    These Short-term municipal securities are of high quality. Margins of
 VMIG2    protection are ample although not so large as in the preceding group.

MIG3 &    Favorable quality. All security elements are accounted for, but the
 VMIG3    undeniable strength of the preceding grades is lacking. Liquidity and
          cash flow protection may be narrow and marketing access for
          refinancing is likely to be less well established.
 
S&P
 
An S&P note rating reflects the liquidity concerns and market access risks
unique to notes. Notes due in three years or less will likely receive a note
rating. Notes maturing beyond three years will most likely receive a long-term
debt rating.
 
    SP-1 Strong capacity to pay principal and interest. Those issues determined
         to possess overwhelming safety characteristics will be given a plus (+)
         designation.
 
    SP-2 Satisfactory capacity to pay principal and interest.
 
    SP-3 Speculative capacity to pay principal and interest.

DESCRIPTION OF PREFERRED STOCK RATINGS
 
MOODY'S
 
     aaa Top-quality preferred stock. This rating indicates good asset
         protection and the least risk of dividend impairment within the
         universe of preferred stocks.
 
      aa High-grade preferred stock. This rating indicates that there is a
         reasonable assurance the earnings and asset protection will remain
         relatively well maintained in the foreseeable future.
 
       a Upper-medium grade preferred stock. While risks are judged to be
         somewhat greater than in the "aaa" and "aa" classification, earnings
         and asset protection are, nevertheless, expected to be maintained at
         adequate levels.
 
     baa Medium-grade preferred stock, neither highly protected nor poorly
         secured. Earnings and asset protection appear adequate at present but
         may be questionable over any great length of time.
 
S&P
 
S&P's preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations.
 
    AAA Highest rating. This rating indicates an extremely strong capacity to
        pay the preferred stock obligations.
 
     AA High-quality, fixed-income security. The capacity to pay preferred stock
        obligations is very strong, although not as overwhelming as for issues
        rated "AAA."
 
       A Backed by a sound capacity to pay the preferred stock obligations,
         although it is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions.
 
    BBB Backed by an adequate capacity to pay the preferred stock obligations.
        Whereas the issuer normally exhibits adequate protection parameters,
        adverse economic conditions or changing circumstances are more likely to
        lead to a weakened capacity to make payments for a preferred stock in
        this category than for issues in the "A" category.
 
SHORT-TERM DEBT RATINGS
 
Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.
 
  TBW-1 Very high degree of likelihood that principal and interest will be paid
        on a timely basis.
 
  TBW-2 While degree of safety regarding timely repayment of principal and
        interest is strong, the relative degree is not as high as for issues
        rated TBW-1.
 
  TBW-3 Lowest investment grade category. While more susceptible to adverse
        developments than obligations with higher ratings, capacity to service
        principal and interest in a timely fashion is considered adequate.
 
  TBW-4 Non-investment grade and, therefore, speculative.

                          A BRIEF PREVIEW OF THE FUNDS
 
             WHAT ARE THE GOALS OF THE ONE GROUP INSTITUTIONAL MONEY MARKET
             FUNDS?
             The Funds are designed to produce high current income with
             liquidity and stability of principal. Each of the Funds will
             use their best efforts to maintain a constant net asset value
             of $1.00 per share, although there is no guarantee that the
             Funds will be able to do so. Please read about each Fund
             before investing.
 
             WHAT ARE THE FUNDS' INVESTMENT STRATEGIES?
             The Funds will invest only in U.S. dollar-denominated
             securities, will maintain an average maturity on a dollar-
             weighted basis of 90 days or less, and will acquire only
             "eligible securities" that present minimal credit risks and
             have a maturity of 397 days or less. The Funds intend to
             comply with Rule 2a-7 under The Investment Company Act of
             1940.
 
             WHO CAN BUY SHARES?
             The Funds are offered only to institutional and other
             accredited investors. For more details, please see the section
             of this prospectus entitled "Purchasing Fund Shares."
 
             HOW DO I PURCHASE AND REDEEM SHARES?
             You may buy and redeem shares of the Funds on any day that the
             Funds are open for business. Purchase and redemption
             procedures are explained in greater detail in "How To Do
             Business With The One Group." For additional information, call
             The One Group Services Company at 1-800-480-4111.
 
             HOW ARE DIVIDENDS PAID?
             Generally, dividends are declared on each business day and are
             distributed periodically. Any capital gains are distributed at
             least annually. Distributions are paid in additional shares of
             the same class unless you elect to take the payment in cash.
             For a more detailed discussion of dividends, see "Dividend
             Policies."

                              MORE ABOUT THE FUNDS
 
PORTFOLIO QUALITY
- ----------------------------------------------------
 
   
Securities will be purchased by the Funds only if Banc One Investment Advisors
determines that they present minimal credit risk under guidelines adopted by the
Board of Trustees. In addition, unless a more specific rating is specified, all
investments of the Funds must be rated in one of the two highest rating
categories described in "Description of Ratings" in the Appendix. If an
investment is unrated, Banc One Investment Advisors must determine that it is of
comparable quality to a rated security. Banc One Investment Advisors will look
at a security's rating at the time of investment. For more information about
ratings, please see "Description of Ratings" in the Appendix.
    
 
ILLIQUID INVESTMENTS
- ----------------------------------------------------
 
Each Fund may invest up to 10% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by The One Group Board of Trustees in determining whether an
investment is illiquid.
 
SPECIAL RISK CONSIDERATIONS
- ----------------------------------------------------
 
NET ASSET VALUE: There is no assurance that the Funds will meet their investment
objectives or be able to maintain a net asset value of $1.00 per share on a
continuous basis.
 
PORTFOLIO TURNOVER: The Funds attempt to increase yield by taking advantage of
short-term market variations. This policy is expected to result in high
portfolio turnover. However, this should not adversely affect the Funds because
they usually do not pay brokerage commissions when purchasing U.S. government
securities.
 
   
FIXED INCOME SECURITIES: The value of the securities held by the Funds will
increase or decrease based on changes in interest rates. If rates increase, the
value of the Funds' investments generally decline. On the other hand, if rates
fall, the value of the investments generally increases. The value of your
investment in a Fund will increase or decrease as the value of a Fund's
investments increase and decrease. While securities with longer duration and
maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment.

                     HOW TO DO BUSINESS WITH THE ONE GROUP
 
PURCHASING
FUND SHARES
- ----------------------------------------------------
 
WHERE CAN I BUY SHARES?
 
You may purchase Fund shares from the following sources:
 
- - The One Group Services Company, and
 
- - Shareholder Servicing Agents. These include investment advisors, brokers,
  financial planners, banks, insurance companies, retirement or 401(k) plan
  sponsors, or other intermediaries. Shares purchased this way will be held for
  you by the Shareholder Servicing Agent.
 
WHO MAY PURCHASE FUND SHARES?
 
Fund shares may be purchased by:
 
- - Commercial and retail institutional investors, including affiliates of BANC
  ONE CORPORATION, that have opened accounts with the Fund's transfer agent,
  State Street Bank and Trust Company, either directly or through a Shareholder
  Servicing Agent.
 
- - Individuals with a net worth, or joint net worth with their spouse, at the
  time of purchase in excess of $1 million.
 
- - Individuals with annual income, or joint annual income with their spouse, at
  the time of purchase in excess of $200,000.
 
- - If you have questions about eligibility, please call The One Group Services
  Company at 1-800-480-4111.
 
WHEN CAN I BUY SHARES?
 
- - Purchases may be made on any business day. This includes any day that the
  Funds are open for business, other than weekends and the following holidays:
  New Years Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
  Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day,
  Thanksgiving, and Christmas.
 
- - Purchase requests will be effective on the day received by The One Group
  Services Company and you will be eligible to receive dividends declared the
  same day, if (i) such purchase orders are received by The One Group Services
  Company before 2:00 p.m., Eastern Standard Time ("EST"), and (ii) the Fund's
  custodian, State Street Bank and Trust Company, receives "federal funds"
  before 4:00 p.m., EST. If State Street Bank and Trust Company does not receive
  federal funds by the cut-off time, the purchase order will not be effective
  until the next business day on which federal funds are timely received by
  State Street Bank and Trust Company.
 
- - If your shares are held by a Shareholder Servicing Agent, it is the
  responsibility of the Shareholder Servicing Agent to send your purchase or
  redemption order to the Fund. Your Shareholder Servicing Agent may have an
  earlier cut-off time for purchase and redemption requests.
 
- - The One Group Services Company can reject a purchase order if it does not
  think that it is in the best interests of a Fund and/or shareholders to accept
  the order.
 
- - Shares are electronically recorded. Therefore, certificates will not be
  issued.
 
HOW MUCH DO SHARES COST?
 
- - Shares are sold at net asset value ("NAV").
 
- - NAV per share is calculated by dividing the total market value of a Fund's
  investments and other assets (minus expenses) by the number of outstanding
  shares. The Funds use their best efforts to maintain their NAV at $1.00,
  although there is no guarantee that they will be able to do so.
 
- - NAV is calculated each business day as of 2:00 p.m. and 4:00 p.m. EST.
 
HOW DO I OPEN AN ACCOUNT?
 
1. Read the prospectus carefully, and select the Fund or Funds most appropriate
   for you.
 
2. Decide how much you want to invest.
 
   - The minimum initial investment is $1,000,000.
 
   - Subsequent investments must be at least $5,000.
 
   - The One Group Services Company may waive these minimums.
 
3. Complete the Account Application Form. Be sure to sign up for all of the
   Account privileges that you plan to take advantage of. Doing so now means
   that you will not have to complete additional paperwork later.
 
4. Send the completed application and a personal check (unless you choose to pay
   by wire or bank transfer) payable to "The One Group" to:
 
   State Street Bank and Trust Company
   c/o The One Group
   P.O. Box 8500
   Boston, MA 02266-8500
 
5. All checks should be in U.S. dollars. Third party checks will not be
   accepted. Redemptions from a Fund will not be permitted for ten (10) calendar
   days if purchases are made by check.
<PAGE>   191

6. If you purchase shares through a Shareholder Servicing Agent, you may be
   required to complete additional forms or follow additional procedures. You
   should contact your Shareholder Servicing Agent regarding purchases,
   exchanges and redemptions.
 
7. If you have any questions, contact your Shareholder Servicing Agent or call
   The One Group Services Company at 1-800-480-4111.
 
CAN I PURCHASE SHARES OVER THE TELEPHONE?
 
Yes. Simply select this option on your Account Application Form and then:
 
- - Contact your Shareholder Servicing Agent or The One Group Services Company at
  1-800-480-4111 to relay your purchase instructions.
 
   
- - Authorize a bank transfer or initiate a wire transfer payable to "The One
  Group" to State Street Bank and Trust Company (see address above).
    
 
- - The One Group uses reasonable procedures to confirm that instructions given by
  telephone are genuine. These procedures include recording telephone
  instructions and asking for personal identification. If these procedures are
  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
   
- - You may revoke your right to make purchases over the telephone by sending a
  letter to:

ARE THERE LIMITS ON EXCHANGES?
 
Yes. The exchange privilege is not intended as a way for you to speculate on
short term movements in the market. Therefore:

  excessive exchange activity.
 
- - Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
  REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH PERIOD.
 
   
- - In addition, The One Group reserves the right to reject any exchange request
  (even those that are not excessive) if the Fund reasonably believes that the

  affect other shareholders.

  the redemption request is received after the time listed above.

ADDITIONAL INFORMATION REGARDING REDEMPTIONS
 
- - All redemptions will be for cash. The redemption price of shares is expected
  to remain constant at $1.00 per share, although there is no assurance that
  this will always be the case.
 
- - If you redeem shares for which you paid by check, and The One Group has not
  yet received payment on the check, The One Group will delay forwarding your
  redemption proceeds for 10 or more days until payment has been collected from
  your bank.
 
- - Because of the high cost of handling small investments, The One Group will
  automatically redeem shares in accounts which, because of shareholder

VOTING RIGHTS
- ----------------------------------------------------
 
The Funds do not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change a Fund's fundamental investment objective, or approve an
investment advisory contract.
 
As a Fund shareholder, you have one vote for each share that you own. Each Fund
votes separately on matters relating solely to that Fund, or which affect that
Fund differently. However, all shareholders will have equal voting rights on
matters that affect all shareholders equally.
 
BANC ONE CORPORATION (100 East Broad Street, Columbus, Ohio, 43271), through its
affiliates, may be deemed for purposes of the Investment Company Act of 1940, to
control the Government Money Market Fund. This is because as of August 5, 1997,
BANC ONE CORPORATION or its affiliates possessed the power to vote substantially
all of the shares of that Fund.
 
DIVIDEND POLICIES
- ----------------------------------------------------
 
DIVIDENDS
 
The Funds generally declare dividends on each business day. Dividends are
distributed on the first business day of each month. Capital gains, if any, for
all Funds are distributed at least annually.
 
DIVIDEND REINVESTMENT
 
You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund, unless you have elected to
take such payment in cash. The price of the shares is the NAV determined
immediately following the dividend record date. Reinvested dividends and
distributions receive the same tax treatment as dividends and distributions paid
in cash.
 
If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8500, Boston, MA
02266-8500, at least 15 days prior to the distribution. The change is effective
upon receipt by State Street.
 
TAX TREATMENT OF THE FUNDS
- ----------------------------------------------------
 
TAX STATUS OF THE FUND
 
Each Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Funds qualify, as they have in the past, they will
pay no federal income tax on the earnings they distribute to shareholders.
 
TAX TREATMENT OF SHAREHOLDERS
- ----------------------------------------------------
 
TAXATION OF SHAREHOLDER TRANSACTIONS
 
A sale, exchange, or redemption of Fund shares will generally produce either a
taxable gain or a loss. You are responsible for any tax liabilities generated by
your transactions.
 
TAXATION OF DISTRIBUTIONS
 
Each Fund will distribute substantially all of its net investment income
(including, for this purpose, net short-term capital gain) to investors on at
least an annual basis. Dividends you receive from a Fund, whether reinvested or
received in cash, will be taxable to you. Dividends from a Fund's net investment
income will be taxable as ordinary income and dividends from a Fund's long-term
capital gains will be taxable to you as such, regardless of how long you have
held the shares.
 
Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid the previous December.
 
TAX INFORMATION
 
The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Funds provide you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Funds or their shareholders.

INVESTMENT RISKS
- ----------------------------------------------------
 
Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities in the Funds may fluctuate, as will the value of your
investment in the Funds. Certain investments are more susceptible to these risks
than others.
 
- - CREDIT RISK. The risk that the issuer of a security, or the counterparty to a
  contract, will default or otherwise become unable to honor a financial
  obligation. Credit risk is generally higher for non-investment grade
  securities. The price of a security can be adversely affected prior to actual
  default as its credit status deteriorates and the probability of default
  rises.
 
   
- - LEVERAGE RISK. The risk associated with securities or practices that multiply
  small index or market movements into large changes in value. Leverage is often
  associated with investments in derivatives, but also may be embedded directly
  in the characteristics of other securities.
    
 
- - LIQUIDITY RISK. The risk that certain securities may be difficult or
  impossible to sell at the time and the price that normally prevails in the
  market. The seller may have to lower the price, sell other securities instead
  or forego an investment opportunity, any of which could have a negative effect
  on fund management or performance. This includes the risk of missing out on an
  investment opportunity because the assets necessary to take advantage of it
  are tied up in less advantageous investments.
 
- - MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
  to produce the intended result. This includes the risk that changes in the
  value of a hedging instrument will not match those of the asset being hedged.
  Incomplete matching can result in unanticipated risks.
 
- - MARKET RISK. The risk that the market value of a security may move up and
  down, sometimes rapidly and unpredictably. These fluctuations may cause a
  security to be worth less than the price originally paid for it, or less than
  it was worth at an earlier time. Market risk may affect a single issuer,
  industry, sector of the economy or the market as a whole. There also is the
  risk that the current interest rate may not accurately reflect existing market
  rates. For fixed income securities, market risk is largely, but not
  exclusively, influenced by changes in interest rates. A rise in interest rates
  typically causes a fall in values, while a fall in rates typically causes a
  rise in values. Finally, key information about a security or market may be
  inaccurate or unavailable.
 
- - PRE-PAYMENT RISK. The risk that the principal repayment of a security will
  occur at an unexpected time, especially that the repayment of a mortgage or
  asset-backed security occurs either significantly sooner or later than
  expected. Changes in pre-payment rates can result in greater price and yield
  volatility. Pre-payments generally accelerate when interest rates decline.
  When mortgage and other obligations are pre-paid, a Fund may have to reinvest
  in securities with a lower yield. Further, with early repayment, a Fund may
  fail to recover any premium paid, resulting in an unexpected capital loss.
 
- - REGULATORY RISK. The risk associated with Federal and state laws which may
  restrict the remedies that a mortgage lender has when a borrower defaults on
  mortgage loans. These laws include restrictions on foreclosures, redemption
  rights after foreclosure, Federal and state bankruptcy and debtor relief laws,
  restrictions on "due on sale" clauses, and state usury laws.
 
INVESTMENT POLICIES
- ----------------------------------------------------
 
Each Fund's investment objective and the following investment policies
summarized below are fundamental. This means that they cannot be changed without
the consent of a majority of the outstanding shares of the Funds. The full text
of the fundamental policies can be found in the Statement of Additional
Information.
 
FUNDAMENTAL POLICIES OF EACH FUND
 
Each Fund:
 
1. Will use its best efforts to maintain a constant net asset value of $1.00 per
   share, although there is no guarantee that the Funds will be able to do so.
 
2. Will not purchase the securities of an issuer if as a result more than 5% of
   its total assets would be invested in the securities of that issuer or the
   Fund would own more than 10% of the outstanding voting securities of that
   issuer. This does not include securities issued or guaranteed by the United
   States, its agencies or instrumen-
<PAGE>   197
 
14
 
   talities, and repurchase agreements involving these securities. This
   restriction applies with respect to 75% of a Fund's total assets. The Funds
   may invest the remaining 25% of their total assets without restriction.
 
3. Will not purchase securities while borrowings (including reverse repurchase
   agreements) exceed 5% of the respective Fund's assets.
 
4. Will not borrow money or issue senior securities, except that the Funds may
   borrow from banks for temporary purposes in amounts not exceeding 10% of
   their total assets at the time of the borrowing.
 
5. Will not mortgage, pledge or hypothecate any assets, except in connection
   with borrowing specified in 4 above and in amounts not in excess of the
   lesser of the dollar amount borrowed or 10% of the value of the respective
   Fund's total assets at the time of its borrowing.
 
FUNDAMENTAL POLICIES OF SPECIFIC FUNDS
 
The Treasury Only Money Market Fund:
 
1. Will not purchase securities other than U.S. Treasury bills, notes and other
   U.S. obligations issued or guaranteed by the U.S. Treasury.
 
2. Will not invest in any securities subject to repurchase agreements.
 
The Government Money Market Fund:
 
1. Will not purchase securities other than those issued or guaranteed by the
   U.S. government or its agencies or instrumentalities, some of which may be
   subject to repurchase agreements.
 
Additional investment policies can be found in the Statement of Additional
Information.

                                    APPENDIX
 
DESCRIPTION OF RATINGS
 
The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.
 
Unrated securities will be treated as non-investment grade securities unless
Banc One Investment Advisors determines that such securities are the equivalent
of investment grade securities. Securities that have received different ratings
from more than one agency are considered investment grade if at least one agency
has rated the security investment grade.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
 
DUFF & PHELPS CREDIT RATING CO. ("DUFF")
 
    D-1+ Highest certainty of timely payment. Short-term liquidity, including
         internal operating factors and/or access to alternative sources of
         funds, is outstanding and safety is just below risk-free U.S. Treasury
         obligations.
 
     D-1 Very high certainty of timely payment. Liquidity factors are excellent
         and supported by good fundamental protection factors. Risk factors are
         minor.
 
    D-1- High certainty of timely payment. Liquidity factors are strong and
         supported by good fundamental protection factors. Risk factors are very
         small.
 
STANDARD & POOR'S CORPORATION ("S&P")
 
     A-1 Highest category of commercial paper. Capacity to meet financial
         commitment is strong. Obligations designated with a plus sign (+)
         indicate that capacity to meet financial commitment is extremely
         strong.
 
     A-2 Issues somewhat more susceptible to adverse effects of changes in
         circumstances and economic conditions than obligations in higher rating
         categories. However, the capacity to meet financial commitments is
         satisfactory.
 
FITCH'S INVESTORS SERVICE, L.P. ("FITCH")
 
    F-1+ Exceptionally strong credit quality. Strongest degree of assurance for
         timely payment.
 
    F-1  Very strong credit quality. Assurance of timely payment is only
         slightly less in degree than issues rated F-1+.
 
   
    F-2  Good credit quality. Satisfactory degree of assurance for timely
         payment, but the margin of safety is not as good as for issues assigned
         F-1+ and F-1 ratings.
    
 
IBCA LIMITED ("IBCA")
 
   
      A1 Highest capacity for timely repayment. Those issues rated A1+ possess a
         particularly strong credit feature.
    
 
      A2 Satisfactory capacity for timely repayment although such capacity may
         be susceptible to adverse changes in business, economic or financial
         conditions.
 
MOODY'S INVESTORS SERVICE ("MOODY'S")
 
 PRIME-1 Superior ability for repayment.
 
 PRIME-2 Strong ability for repayment.
 
DESCRIPTION OF BANK RATINGS
 
MOODY'S
 
         These ratings represent Moody's opinion of a bank's intrinsic safety
         and soundness.
 
       A These banks possess exceptional intrinsic financial strength. Typically
         they will be major financial institutions with highly valuable and
         defensible business franchises, strong financial fundamentals, and a
         very attractive and stable operating environment.
 
       B These banks possess strong intrinsic financial strength. Typically,
         they will be important institutions with valuable and defensible
         business franchises, good financial fundamentals, and an attractive and
         stable operating environment.
 
       C These banks possess good intrinsic financial strength. Typically, they
         will be institutions with valuable and defensible business franchises.
         These banks will demonstrate either acceptable financial fundamentals
         within a stable operating environment, or better than average financial
         fundamentals within an unstable operating environment.

S&P
 
S&P's credit rating is a current opinion of an obligor's overall financial
capacity (its creditworthiness) to pay its financial obligation.
 
    AAA The highest rating assigned by S&P. The obligor's capacity to meet its
        financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A The obligation is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than obligations in
         higher rated categories. However, the obligor's capacity to meet its
         financial commitment on the obligation is still strong.
 
DESCRIPTION OF INSURANCE RATINGS
 
MOODY'S
 
These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.
 
    Aaa Insurance companies rated in this category offer exceptional financial
        security. While the financial strength of these companies is likely to
        change, such changes as can be visualized are most unlikely to impair
        their fundamentally strong position.
 
      Aa These insurance companies offer excellent financial security. Together
         with the Aaa group, they constitute what are generally known as high
         grade companies. They are rated lower than Aaa companies because
         long-term risks appear somewhat larger.
 
       A Insurance companies rated in this category offer good financial
         security. However, elements may be present which suggest a
         susceptibility to impairment sometime in the future.
 
S&P
 
S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.
 
    AAA This is the highest rating assigned by S&P. The obligor's capacity to
        meet its financial commitment on the obligation is extremely strong.
 
     AA AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
       A An obligation rated A is somewhat more susceptible to the adverse
         effects of changes in circumstances and economic conditions than
         obligations in higher rated categories. However, the obligor's capacity
         to meet its financial commitment on the obligation is still strong.
 
DESCRIPTION OF CORPORATE/MUNICIPAL BOND RATINGS
 
S&P
 
Investment Grade
 
    AAA The highest rating. The rating indicates an extremely strong capacity to
        meet its financial commitment.
 
     AA Differs from AAA issues only in a small degree. The obligor's capacity
        to meet its financial commitment is very strong.
 
       A These bonds are somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions than debt in higher
         rated categories. However, capacity to meet its financial commitment on
         the obligation is still strong.
 
    BBB Exhibits adequate protection parameters. However, adverse economic
        conditions or changing circumstances are more likely to lead to a
        weakened capacity to meet its financial commitment on the obligation.
 
Speculative Grade
 
     BB Less vulnerable to non-payment than other speculative issues. However,
        these bonds face major ongoing uncertainties or exposure to adverse
        business, financial or economic conditions which could lead to
        inadequate capacity to meet financial commitment on the obligation.
 
       B More vulnerable to non-payment than obligations rated BB, but currently
         has the capacity to meet its financial commitment on the obligation.
         Adverse business, financial or economic conditions will likely impair
         capacity or willingness to meet its financial commitment on the
         obligation.
 
    CCC Currently vulnerable to non-payment, and is dependent upon favorable
        business, financial, and economic conditions to meet its financial
        commitment on the obligation. In the event of adverse busi-
<PAGE>   200
                                                                              17
 
        ness, financial, or economic conditions, they are not likely to have the
        capacity to meet its financial commitment on the obligation.
 
      CC Currently highly vulnerable to non-payment.
 
       C This rating may be used to cover a situation where a bankruptcy
         petition has been filed, or similar action has been taken, but payments
         on this obligation are being continued.
 
       D Bonds in payment default.
 
Ratings from AA to CCC may be modified by a plus (+) or minus (-) to show
relative standing within the major rating categories.
 
MOODY'S
 
Investment Grade
 
    Aaa Best quality. They carry the smallest degree of investment risk and are
        generally referred to as "gilt edged." Interest payments are protected
        by a large, or an exceptionally stable, margin and principal is secure.
 
      Aa High quality by all standards. Margins of protection may not be as
         large as in Aaa securities, fluctuation of protective elements may be
         greater, or there may be other elements present that make the long-term
         risks appear somewhat larger than in Aaa securities.
 
       A These bonds possess many favorable investment attributes and are to be
         considered as upper-medium grade obligations. Factors giving security
         to principal and interest are considered adequate, but elements may be
         present which suggest a susceptibility to impairment sometime in the
         future.
 
    Baa These bonds are considered medium-grade obligations (i.e., they are
        neither highly protected nor poorly secured). Interest payments and
        principal security appear adequate for the present but certain
        protective elements may be lacking or may be characteristically
        unreliable over any great length of time. Such bonds lack outstanding
        investment characteristics and in fact have speculative characteristics
        as well.
 
Non-Investment Grade
 
      BA These bonds have speculative elements; their future cannot be
         considered as well assured. The protection of interest and principal
         payments may be very moderate and thereby not well safeguarded during
         good and bad times over the future.
 
       B These bonds lack the characteristics of a desirable investment (i.e.,
         potentially low assurance of timely interest and principal payments or
         maintenance of other contract terms over any long period of time may be
         small).
 
     Caa Bonds in this category have poor standing and may be in default. These
         bonds carry an element of danger with respect to principal and interest
         payments.
 
      Ca Speculative to a high degree and could be in default or have other
         marked shortcomings. Ca is the lowest rating.
 
DESCRIPTION OF MUNICIPAL NOTE RATINGS
 
MOODY'S
     MIG1 & VMIG1 Short-term municipal securities rated MIG1 or VMIG1 are of
         the best quality. They have strong protection from established cash 
         flows, superior liquidity support or demonstrated broad-based access 
         to the market for refinancing.

     MIG2 & VMIG2 These Short-term municipal securities are of high quality.
         Margins of protection are ample although not so large as in the 
         preceding group.

     MIG3 & VMIG3 Favorable quality. All security elements are accounted for,
         but the undeniable strength of the preceding grades is lacking. 
         Liquidity and cash flow protection may be narrow and marketing 
         access for refinancing is likely to be less well established.
 
S&P
 
An S&P note rating reflects the liquidity concerns and market access risks
unique to notes. Notes due in three years or less will likely receive a note
rating. Notes maturing beyond three years will most likely receive a long-term
debt rating.
 
    SP-1 Strong capacity to pay principal and interest. Those issues determined
         to possess overwhelming safety characteristics will be given a plus (+)
         designation.
 
    SP-2 Satisfactory capacity to pay principal and interest.
 
    SP-3 Speculative capacity to pay principal and interest.
 
DESCRIPTION OF PREFERRED STOCK RATINGS
 
MOODY'S
 
     Aaa Top-quality preferred stock. This rating indicates good asset
         protection and the
<PAGE>   201
 
18
 
         least risk of dividend impairment within the universe of preferred
         stocks.
 
      aa High-grade preferred stock. This rating indicates that there is a
         reasonable assurance the earnings and asset protection will remain
         relatively well maintained in the foreseeable future.
 
       a Upper-medium grade preferred stock. While risks are judged to be
         somewhat greater than in the "aaa" and "aa" classification, earnings
         and asset protection are, nevertheless, expected to be maintained at
         adequate levels.
 
     baa Medium-grade preferred stock, neither highly protected nor poorly
         secured. Earnings and asset protection appear adequate at present but
         may be questionable over any great length of time.
 
S&P
 
S&P's preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations.
 
    AAA Highest rating. This rating indicates an extremely strong capacity to
        pay the preferred stock obligations.
 
     AA High-quality, fixed-income security. The capacity to pay preferred stock
        obligations is very strong, although not as overwhelming as for issues
        rated "AAA."
 
       A Backed by a sound capacity to pay the preferred stock obligations,
         although it is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions.
 
    BBB Backed by an adequate capacity to pay the preferred stock obligations.
        Whereas the issuer normally exhibits adequate protection parameters,
        adverse economic conditions or changing circumstances are more likely to
        lead to a weakened capacity to make payments for a preferred stock in
        this category than for issues in the "A" category.
 
SHORT-TERM DEBT RATINGS
 
Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.
 
  TBW-1 Very high degree of likelihood that principal and interest will be paid
        on a timely basis.
 
  TBW-2 While degree of safety regarding timely repayment of principal and
        interest is strong, the relative degree is not as high as for issues
        rated TBW-1.
 
  TBW-3 Lowest investment grade category. While more susceptible to adverse
        developments than obligations with higher ratings, capacity to service
        principal and interest in a timely fashion is considered adequate.
 
  TBW-4 Non-investment grade and, therefore, speculative.

                        A BRIEF PREVIEW OF THE FUNDS
 
             WHAT ARE THE GOALS OF THE ONE GROUP INVESTOR FUNDS?
             The Funds are designed for a variety of investment objectives,
             including total return, capital appreciation, current income,
             and long-term capital growth. Each Fund pursues a different
             objective and involves different risks. Please read about each
             Fund before investing.
 
             WHAT ARE THE FUNDS' INVESTMENT STRATEGIES?
             The Funds normally will invest in a diversified group of One
             Group mutual funds, which invest primarily in equity, fixed
             income and money market instruments. Shares are available for
             long-term investors, including tax-advantaged retirement
             accounts; the Funds should not be used for short-term trading
             purposes. The Funds' investment return is diversified by its
             investment in the underlying mutual funds which invest in
             growth and income stocks, foreign securities, debt securities,
             and cash or cash equivalents. The underlying mutual funds in
             which the Fund will invest have the following characteristics:

</TABLE>
 
             WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUNDS?
             The investments of each Fund are concentrated in the
             underlying funds, so each Fund's investment performance is
             directly related to the performance of the underlying funds.
             Each Fund's net asset value will fluctuate with changes in the
             equity and bond markets and the value of the mutual funds in
             which it invests. In addition, as a matter of fundamental
             policy, each Fund must allocate its investments among the
             underlying funds. As a result, the Funds do not have the same
             flexibility to invest as a mutual fund without such
             constraints. For more information about risks, please read
             "More About the Funds" and "Investment Risks."
 
             WHAT CLASSES OF SHARES ARE AVAILABLE?
             The Funds currently offer four classes of Shares: Class A,
             Class B, Class C and Fiduciary Class. Class A, Class B and
             Class C shares are offered to the general public. Fiduciary
             Class shares are offered to institutional investors, including
             affiliates of BANC ONE CORPORATION and any bank, depository
             institution, insurance company, pension plan or other
             organization authorized to act in fiduciary, advisory, agency,
             custodial or similar capacities. The section called "How To Do
             Business With The One Group" will provide more information.
             Fiduciary Class shares are not available to Individual
             Retirement Accounts ("IRA").
 
             HOW DO I PURCHASE AND REDEEM SHARES?
             You may buy and redeem shares of the Funds on any day that the
             Funds are open for business. Purchase and redemption
             procedures are explained in greater detail in "How To Do
             Business With The One Group." For additional information, call
             The One Group Services Company at 1-800-480-4111.
 
             HOW ARE DIVIDENDS PAID?
             Generally, dividends are declared monthly and distributed on
             the first business day of each month. Any capital gains are
             distributed at least annually. Distributions are paid in
             additional shares of the same class unless you elect to take
             the payment in cash. For a more detailed discussion of
             dividends, see "Dividend Policies."
 
             WHO MANAGES THE FUNDS?
             Banc One Investment Advisors Corporation ("Banc One Investment
             Advisors"), an indirect subsidiary of BANC ONE CORPORATION,
             serves as the advisor of the Funds. Banc One Investment
             Advisors is paid a fee for its services. Banc One Investment
             Advisors also serves as the advisor to the underlying mutual
             funds, for which it receives a fee.

THE ONE GROUP(R)
INVESTOR GROWTH FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks long-term capital appreciation by investing primarily in a
diversified group of The One Group mutual funds which invest primarily in equity
securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests 80% to 100% of its total assets in nine mutual funds of The One
Group which invest primarily in equity securities, up to 20% of its total assets
in five mutual funds of The One Group that invest primarily in fixed income
securities, and up to 10% of its assets in one money market fund of The One
Group.
 
[ICON] PORTFOLIO SECURITIES
The Fund will invest in the underlying mutual funds within the following range:

</TABLE>
 
[ICON] RISK CONSIDERATIONS
The Fund's investments are concentrated in other mutual funds, so the Fund's
investment performance is directly related to the performance of those mutual
funds. In addition, as a matter of fundamental policy, the Fund must allocate
its investments primarily among the mutual funds. As a result, the Fund's
investment flexibility is limited. The Fund may invest in a mutual fund which
invests in medium or lower grade bonds, which can be volatile. See "Special Risk
Considerations."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Investment Advisory fees have been revised to reflect fee waivers. Without
    the waiver, Investment Advisory fees would be .05% for all classes of
    shares.
(5) Due to 12b-1 fees, long-term Class A, Class B, and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A.
(6) Without the voluntary reduction of fees, Total Operating Expenses would be
    .59% for Class A shares, 1.24% for Class B shares, 1.24% for Class C shares,
    and .24% for Fiduciary Class shares.
 
The Fund will indirectly pay a portion of the expenses incurred by the
underlying funds. The following chart provides the expense ratio for each
underlying fund in which the Fund invests (based on the current fund
prospectus). Some of these expense ratios may include a voluntary reduction of
investment advisory fees.

THE ONE GROUP(R)
INVESTOR GROWTH & INCOME FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks long-term capital appreciation and growth of income by investing
primarily in a diversified group of The One Group mutual funds which invest
primarily in equity securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests 60% to 80% of its total assets in nine mutual funds of The One
Group which invest primarily in equity securities, 20% to 40% of its total
assets in five mutual funds of The One Group that invest primarily in fixed
income securities, and up to 10% of its assets in one money market fund of The
One Group.
 
[ICON] PORTFOLIO SECURITIES
The Fund will invest in the underlying mutual funds within the following ranges:

</TABLE>
 
[ICON] RISK CONSIDERATIONS
The Fund's investments are concentrated in other mutual funds, so the Fund's
investment performance is directly related to the performance of those mutual
funds. In addition, as a matter of fundamental policy, the Fund must allocate
its investments primarily among the mutual funds. As a result, the Fund's
investment flexibility is limited. The Fund may invest in a mutual fund which
invests in medium or lower grade bonds, which can be volatile. See "Special Risk
Considerations."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Investment Advisory fees have been revised to reflect fee waivers. Without
    the waiver, Investment Advisory fees would be .05% for all classes of
    shares.
(5) Due to 12b-1 fees, long-term Class A, Class B, and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A.
(6) Without the voluntary reduction of fees, Total Operating Expenses would be
    .59% for Class A shares, 1.24% for Class B shares, 1.24% for Class C shares,
    and .24% for Fiduciary Class shares.
 
The Fund will indirectly pay a portion of the expenses incurred by the
underlying funds. The following chart provides the expense ratio for each
underlying fund (based on the current fund prospectus). Some of these expense
ratios may include a voluntary reduction of investment advisory fees.

After combining the total operating expenses of the Fund with those of the
underlying funds, the estimated average weighted expense ratio for Class A
shares is 1.28%, for Class B shares is 2.03%, for Class C shares is 2.03%, and
for Fiduciary Class shares is 1.03%.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charges; (2) 5% annual return; and
(3) redemption at the end of each time period.

THE ONE GROUP(R) INVESTOR GROWTH & INCOME FUND    FINANCIAL HIGHLIGHTS
 
   
The Financial Highlights are intended to help you understand the Fund's
financial performance for the past 10 years, or since inception if less than 10
years. The total returns in the table represent the rate a shareholder would
have earned on an investment in the Fund (assuming reinvestment of all dividends
and distributions). This information has been derived from financial statements
audited by Coopers & Lybrand L.L.P., whose report, along with the Fund's
financial statements, is included in the Statement of Additional Information,
which is available upon request.

THE ONE GROUP(R)
INVESTOR BALANCED FUND
[ICON] INVESTMENT OBJECTIVE
The Fund seeks high total return consistent with the preservation of capital by
investing primarily in a diversified group of The One Group mutual funds which
invest primarily in equity and fixed income securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests 40% to 60% of its total assets in nine mutual funds of The One
Group which invest primarily in equity securities, 40% to 60% of its total
assets in five mutual funds of The One Group which invest primarily in fixed
income securities, and up to 10% of its assets in one money market fund of The
One Group.
 
[ICON] PORTFOLIO SECURITIES
The Fund will invest in the underlying mutual funds within the following range:

The One Group(R) Equity Index Fund                     0-40%
</TABLE>
 
[ICON] RISK CONSIDERATIONS
The Fund's investments are concentrated in other mutual funds, so the Fund's
investment performance is directly related to the performance of those mutual
funds. In addition, as a matter of fundamental policy, the Fund must allocate
its investments primarily among the mutual funds. As a result, the Fund's
investment flexibility is limited. The Fund may invest in a mutual fund which
invests in medium or lower grade bonds, which can be volatile. See "Special Risk
Considerations."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Investment Advisory fees have been revised to reflect fee waivers. Without
    the waiver, Investment Advisory fees would be .05% for all classes of
    shares.
(5) Due to 12b-1 fees, long term Class A, Class B, and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A.
(6) Without the voluntary reduction of fees, Total Operating Expenses would be
    .59% for Class A shares, 1.24% for Class B shares, 1.24% for Class C Shares,
    and .24% for Fiduciary Class shares.
 
The Fund will indirectly pay a portion of the expenses incurred by the
underlying funds. The following chart provides the expense ratio for each
underlying fund in which the Fund invests (based on the current fund
prospectus). Some of these expense ratios may include a voluntary reduction of

diversified group of The One Group mutual funds which invest primarily in equity
and fixed income securities.
 
[ICON] INVESTMENT STRATEGY
The Fund invests 20% to 40% of its total assets in nine mutual funds of The One
Group which invest primarily in equity securities, 60% to 80% of its total

income securities, and up to 10% of its assets in one money market fund of The
One Group.

[ICON] RISK CONSIDERATIONS
The Fund's investments are concentrated in other mutual funds, so the Fund's
investment performance is directly related to the performance of those mutual
funds. In addition, as a matter of fundamental policy, the Fund must allocate
its investments primarily among the mutual funds. As a result, the Fund's
investment flexibility is limited. The Fund may invest in a mutual fund which
invests in medium or lower grade bonds, which can be volatile. See "Special Risk
Considerations."

(1) If you buy or sell shares through a Shareholder Servicing Agent, you may be
    charged separate transaction fees by the Shareholder Servicing Agent. In
    addition, a $7.00 charge is deducted from redemption amounts paid by wire.
(2) Except for purchases of $1 million or more. Please see "Sales Charges."
(3) Expense information has been restated to reflect current fees.
(4) Investment Advisory fees have been revised to reflect fee waivers. Without
    the waiver, Investment Advisory fees would be .05% for all classes of
    shares.
(5) Due to 12b-1 fees, long term Class A, Class B, and Class C shareholders may
    pay more than the equivalent of the maximum front-end sales charges
    permitted by the rules of the National Association of Securities Dealers.
    Without the voluntary waiver, 12b-1 fees would be .35% for Class A.
(6) Without the voluntary reduction of fees, Total Operating Expenses would be
    .59% for Class A shares, 1.24% for Class B shares, 1.24% for Class C shares,
    and .24% for Fiduciary Class shares.
 
The Fund will indirectly pay a portion of the expenses incurred by the
underlying funds. The following chart provides the expense ratio for each
underlying fund in which the Fund invests (based on the current fund
prospectus). Some of these expense ratios may include a voluntary reduction of
investment advisory fees.

After combining the total operating expenses of the Fund with those of the
underlying funds, the estimated average weighted expense ratio for Class A
shares is 1.15%, for Class B shares is 1.90%, for Class C shares is 1.90%, and
for Fiduciary Class shares is .90%.
 
 EXAMPLE
An investor would pay the following expenses on a $1,000 investment in the Fund,
assuming: (1) payment of the maximum sales charges; (2) 5% annual return; and
(3) redemption at the end of each time period.

ILLIQUID INVESTMENTS
- ----------------------------------------------------
 
Each Fund may invest up to 15% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by The One Group Board of Trustees in determining whether an
investment is illiquid.
 
TEMPORARY
DEFENSIVE POSITION
- ----------------------------------------------------
 
Sometimes Banc One Investment Advisors decides that because of market conditions
the Funds should temporarily be invested in instruments other than the
underlying mutual funds. Therefore, the Funds are permitted for temporary
defensive purposes to invest up to 100% of their assets in short-term fixed
income securities. These securities include obligations of the U.S. Government
and its agencies and instrumentalities, commercial paper, bank certificates of
deposit, repurchase agreements, bankers' acceptances, variable amount master
demand notes and bank money market deposit accounts. The Funds also may hold
cash for liquidity purposes.
 
To the extent that the Funds are engaged in a temporary defensive position, they
will not be pursuing their investment objective.
 
SPECIAL RISK
CONSIDERATIONS
- ----------------------------------------------------
 
EQUITY FUNDS Because equity funds invest primarily in equity securities, which
fluctuate in value, the funds' shares will fluctuate in value. In addition,
certain investment management techniques that the funds may use, such as the
purchase and sale of futures, options and forward commitments, could expose the
funds to potentially greater risk of loss than more traditional equity
investments.
 
   
FIXED-INCOME FUNDS Investments in fixed income securities (for example, bonds)
will increase or decrease in value based on changes in interest rates. If rates
increase, the value of a Fund's investments generally declines. On the other
hand, if rates fall, the value of the investments generally increases. The value
of your investment in a Fund will increase and decrease as the value of a Fund's
investments increase and decrease. While securities with longer duration and
maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment.
    
 
INDEX FUNDS An index fund's investment objective is to track the performance of
a specified index. Therefore, securities may be purchased, retained and sold by
an index fund at times when an actively managed fund would not do so. As a
result, you can expect greater risk of loss (and a correspondingly greater
prospect of gain) from changes in the value of securities that are heavily
weighted in the index than would be the case if the funds were not fully
invested in such securities. Because of this, an index fund's share price can be
volatile and you should be able to handle sudden, and sometimes substantial,
fluctuation in the value of your investment.

INTERNATIONAL FUNDS Funds investing in foreign securities are subject to special
risks. These risks may include future unfavorable political and economic
developments, possible withholding taxes, seizure of foreign deposits, currency
controls, higher transaction costs, and delayed settlements of transactions.
Securities of some foreign companies are less liquid, and their prices more
volatile, than securities of comparable U.S. companies. Additionally, there may
be less public information available about foreign issuers. Finally, since the
funds may invest in securities denominated in foreign currencies, changes in
exchange rates may affect the value of investments in the funds.

SMALL CAPITALIZATION FUNDS Smaller, less seasoned companies may be subject to
greater business risk than larger, established companies. They may be more
vulnerable to changes in economic conditions, specific industry conditions,
market fluctuations and other factors affecting the profitability of other
companies. Therefore, the stock price of smaller capitalization companies may be
subject to greater price fluctuations than that of larger, established
companies. Due to these and other risk factors, the price movement of the
securities held by the funds may be volatile and the net asset value of shares
of the funds may fluctuate.

                     HOW TO DO BUSINESS WITH THE ONE GROUP
 
                                                                              15
 
PURCHASING
FUND SHARES
- ----------------------------------------------------
 
WHERE CAN I BUY SHARES?
 
You may purchase Fund shares from the following sources:
 
- - The One Group Services Company, and
 
- - Shareholder Servicing Agents. These include investment advisors, brokers,
  financial planners, banks, insurance companies, retirement or 401(k) plan
  sponsors, or other intermediaries. Shares purchased this way will be held for
  you by the Shareholder Servicing Agent.
 
WHEN CAN I BUY SHARES?
 
- - Purchases may be made on any business day. This includes any day that the
  Funds are open for business, other than weekends and the following holidays:
  New Years Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
  Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas.
 
- - Purchase requests received by The One Group Services Company before 4:00 p.m.
  Eastern Standard Time ("EST"), will be effective that day.
 
- - Purchase orders may be cancelled by the Fund's Custodian, State Street Bank
  and Trust Company, if it does not receive "federal funds" by 4:00 p.m. EST (i)
  on the business day after the order is placed if you are buying Fiduciary
  Class shares, and (ii) on the third business day if you are purchasing Class
  A, Class B and Class C shares.
 
- - If your shares are held by a Shareholder Servicing Agent, it is the
  responsibility of the Shareholder Servicing Agent to send your purchase or
  redemption order to the Fund. Your Shareholder Servicing Agent may have an
  earlier cut-off time for purchase and redemption requests.
 
- - The One Group Services Company can reject a purchase order if it does not
  think that it is in the best interests of a Fund and/or its shareholders to
  accept the order.
 
- - Shares are electronically recorded. Therefore, certificates will not be
  issued.
 
WHAT KIND OF SHARES CAN I BUY?
 
The One Group offers the following classes of shares:
 
- - Class A, Class B and Class C shares are available to the general public.
 
- - Fiduciary Class shares are available to institutional investors and any
  organization authorized to act in a fiduciary, advisory, custodial or agency
  capacity. We will refer to these entities as "Intermediaries."
 
- - If you intend to hold your shares for six or more years, Class B shares may be
  appropriate for you. If you intend to hold your shares for less than six
  years, you may want to consider Class A or Class C shares.
 
   
The One Group Fund Direct IRA. The One Group offers a retirement plan and, in
1998, will offer an education plan. These plans allow participants to defer
taxes while their retirement and education savings grow. The education IRA
requires a minimum investment of $500. Call The One Group Services Company at
1-800-480-4111 for an Adoption Agreement.
    
 
HOW MUCH DO SHARES COST?
 
- - Shares are sold at net asset value ("NAV") plus a sales charge, if any.
 
- - Each class of shares in each Fund has a different NAV. This is primarily
  because each class has different distribution expenses.
 
- - NAV per share is calculated by dividing the total market value of a Fund's
  investments and other assets allocable to a class (minus class expenses) by
  the number of outstanding shares in that class.
 
- - A Fund's NAV changes every day. NAV is calculated each business day at 4:00
  p.m. EST.
 
HOW DO I OPEN AN ACCOUNT?
 
1. Read the prospectus carefully, and select the Fund or Funds most appropriate
   for you.
 
2. Decide how much you want to invest.
 
   - The minimum initial investment is $1,000 ($100 for employees of BANC ONE
     CORPORATION and its affiliates).
 
   - Subsequent investments must be at least $100 ($25 for employees of BANC ONE
     CORPORATION and its affiliates).
 
   - You may purchase no more than $250,000 of Class B shares at one time.
 
   - The One Group Services Company may waive these minimums.
 
3. Complete the Account Application Form. Be sure to sign up for all of the
   Account privileges that you plan to take advantage of. Doing so now means
   that you will not have to complete additional paperwork later.

4. Send the completed application and a personal check (unless you choose to pay
   by wire or bank transfer) payable to "The One Group" to:
 
   State Street Bank and Trust Company
   c/o The One Group
   P.O. Box 8500
   Boston, MA 02266-8500
 
   Contributions to Fund Direct IRAs should be made payable to "State Street
   Bank and Trust Company for the Benefit of (your name)."
 
5. All checks should be in U.S. dollars. Third party checks will not be
   accepted. Redemptions from a Fund will not be permitted for ten (10) calendar
   days if purchases are made by check or under the Systematic Investment Plan
   (see below).
 
6. If you purchase shares through a Shareholder Servicing Agent, you may be
   required to complete additional forms or follow additional procedures. You
   should contact your Shareholder Servicing Agent regarding purchases,
   exchanges and redemptions.
 
7. If you have any questions, contact your Shareholder Servicing Agent or call
   The One Group Services Company at 1-800-480-4111.
 
CAN I PURCHASE SHARES OVER THE TELEPHONE?
 
Yes. Simply select this option on your Account Application Form and then:
 
- - Contact your Shareholder Servicing Agent or The One Group Services Company at
  1-800-480-4111 to relay your purchase instructions.
 
- - Send a personal check made payable to "The One Group" to State Street Bank and
  Trust Company (see address above), authorize a bank transfer or initiate a
  wire transfer.
 
- - The One Group uses reasonable procedures to confirm that instructions given by
  telephone are genuine. These procedures include recording telephone
  instructions and asking for personal identification. If these procedures are
  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
   
- - You may revoke your right to make purchases over the telephone by sending a
  letter to:
    
 
  State Street Bank and Trust Company
  c/o The One Group
  P.O. Box 8500

CAN I AUTOMATICALLY INVEST ON A SYSTEMATIC BASIS?
 
Yes. After your Account is established, you may purchase additional Class A,
Class B and Class C shares by making automatic monthly investments from your
bank account. The minimum initial investment is still $1,000, but minimum
automatic additions are only $25. The One Group Services Company may waive these
minimums. To establish a Systematic Investment Plan:
 
- - Select the "Systematic Investment Plan" option on the Account Application
  Form.
 
- - Provide the necessary information about the bank account from which your
  investments will be made.
 
- - Shares purchased under a Systematic Investment Plan may not be redeemed for
  ten (10) calendar days.
 
- - The One Group currently does not charge for this service, but may impose a
  charge in the future. However, your bank may impose a charge for debiting your
  bank account.
 
   
- - You may revoke your right to make systematic investments by sending a letter

CONVERSION FEATURE
 
Your Class B shares automatically convert to Class A shares after eight years
(measured from the end of the month in which they were purchased).
 
- - After conversion, your shares will be subject to the lower distribution and
  shareholder servicing fees charged on Class A shares.
 
- - You will not be assessed any sales charges or fees for conversion of shares,
  nor will you be subject to any tax.
 
- - Because the share price of the Class A shares may be higher than that of the
  Class B shares at the time of conversion, you may receive fewer Class A
  shares; however, the dollar value will be the same.
 
- - If you have exchanged Class B shares of one Fund for Class B shares of
  another, the time you held the shares in each Fund will be added together.
 
SALES CHARGES
- ----------------------------------------------------
 
   
The One Group Services Company compensates Shareholder Servicing Agents who sell
shares of The One Group. Compensation comes from: sales charges, 12b-1 fees and
payment by The One Group Services Company from its own resources. The One Group
Services Company, at its own expense, also will provide promotional incentives
in the form of travel expenses, lodging and bonuses to licensed individuals who
sell shares of the Funds, as well as vacation trips (including lodging at luxury
resorts), tickets to entertainment events, and merchandise.

   sales charge at the time of purchase, you will be charged the equivalent of
   1% of the purchase price if you redeem any or all of the Class A shares
   within one year of purchase.
 
 CLASS B SHARES
 
Class B shares are offered at NAV, without any up-front sales charges. However,
if you redeem these shares within six years of the purchase date, you will be
assessed a Contingent Deferred Sales Charge ("CDSC") according to the following
schedule:

The One Group Services Company pays a commission of 4.00% of the original
purchase price to Shareholder Servicing Agents who sell Class B shares.
 
 CLASS C SHARES
 
Class C shares are offered at NAV, without any up-front sales charge. However,
if you redeem your shares within one year of the purchase date, you will be
assessed a CDSC as follows:
 
<TABLE>
<CAPTION>
                          CDSC AS A % OF DOLLAR

  After first year                  None
</TABLE>
 
Shareholder Servicing Agents selling Class C shares receive a commission of
1.00% of the original purchase price from The One Group Services Company.
 
How the CDSC is Calculated
 
- - The Fund assumes that all purchases made in a given month were made on the
  first day of the month.
 
- - The CDSC is based on the current market value or the original cost of the
  shares, whichever is less.
 
- - A sales charge is not imposed on increases in NAV above the initial purchase
  price, nor is a sales charge assessed on shares acquired through reinvestment
  of dividends or capital gains distributions.
 
- - To keep your CDSC as low as possible, the Fund first will redeem any shares in
  your account that carry no CDSC, starting with Class A Shares. After that, the
  Fund will redeem the shares you have held for the longest time and thus have
  the lowest CDSC.
<PAGE>   222

12B-1 FEES
 
12b-1 fees are paid by The One Group to The One Group Services Company as
compensation for its services and expenses. The One Group Services Company in
turn pays all or part of the 12b-1 fee to Shareholder Servicing Agents that sell
shares of The One Group.
 
- - The 12b-1 fees vary by share class as follows:
 
   1. Class A shares pay a 12b-1 fee of .35% of the average daily net assets of
      the Fund, which is currently being waived to .25%.
 
   2. Class B and Class C shares pay a 12b-1 fee of 1.00% of the average daily
      net assets of the Fund. This will cause expenses for Class B and Class C
      shares to be higher and dividends to be lower than for Class A shares.
 
   3. There are no 12b-1 fees for Fiduciary Class shares.
 
- - 12b-1 fees, together with the CDSC, help The One Group Services Company sell
  Class B and Class C shares without an "up-front" sales charge by defraying the
  costs of advancing brokerage commissions and other expenses paid to
  Shareholder Servicing Agents.
 
- - The One Group Services Company may use up to .25% of the fees for shareholder
  servicing and up to .75% for distribution. During the last fiscal year, The
  One Group Services Company received 12b-1 fees totaling .25%, 1.00% and 1.00%
  of the average daily net assets of Class A, Class B and Class C shares,
  respectively.
 
- - The One Group Services Company may pay 12b-1 fees to its affiliates and to
  Banc One Investment Advisors and its affiliates (or any sub-advisor) for
  brokerage and other agency transactions.
 
SALES CHARGE REDUCTIONS AND WAIVERS
- ----------------------------------------------------
 
REDUCING YOUR CLASS A SALES CHARGES
 
There are several ways you can reduce the sales charges you pay on Class A
shares:
 
1. Right of Accumulation: You may add the market value of any Class A, Class B
   or Class C shares of a Fund (except a money market fund) that you (and your
   spouse and minor children) already own to the amount of your next Class A
   purchase for purposes of calculating the sales charge. An Intermediary also
   may take advantage of this option.
 
2. Letter of Intent: With an initial investment of $2,000, you may purchase
   Class A shares of one or more funds over the next 13 months and pay the same
   sales charge that you would have paid if all shares were purchased at once. A
   percentage of your investment will be held in escrow until the full amount
   covered by the Letter of Intent has been invested.
 
To take advantage of the accumulation privilege or letter of intent, complete
the appropriate section of your fund application, or contact your Shareholder
Servicing Agent. To determine if you are eligible for the accumulation
privilege, contact The One Group Services Company at 1-800-480-4111. These
programs may be terminated or amended at any time.

No sales charge is imposed on Class A shares of the Funds if the shares were:

2. Acquired in exchange for other Fund shares if a comparable sales charge has
   been paid for the exchanged shares.

     and their subsidiaries and affiliates.
 
   - An investment sub-advisor of a fund of The One Group and such sub-advisor's
     subsidiaries and affiliates.
 
4. Bought by:
 
   - Affiliates of BANC ONE CORPORATION and certain accounts (other than IRA
     Accounts) for which an Intermediary acts in a fiduciary, advisory, agency,
     custodial or similar capacity.
 
   - Accounts to which a bank or broker-dealer charges an asset allocation fee,
     provided the bank or broker-dealer has an agreement with The One Group
     Services Company.
 
   - Retirement and deferred compensation plans and trusts used to fund those
     plans, including, but not limited to, those defined in sections 401(a),
     403(b) or 457 of the Internal Revenue Code and "rabbi trusts."

5. Bought with proceeds from the sale of Fiduciary Class shares of a Fund of The
   One Group or acquired in an exchange of Fiduciary Class shares of a Fund for

   days of the sale or distribution.
 
6. Bought with proceeds from the sale of shares of a mutual fund (other than a
   fund of The One Group) for which a sales charge was paid, but only if the
   purchase is made within 60 days of the sale or distribution.

  Group.

days written notice.
<PAGE>   224
 
20
 
WHEN ARE EXCHANGES PROCESSED?
 
Exchanges are processed the same business day they are received, provided:
 
- - State Street Bank and Trust Company receives the request by 4:00 p.m. EST.
 
- - You have provided The One Group with all of the information necessary to
  process the exchange.
 
- - You have received a current prospectus of the Fund or Funds in which you wish
  to invest.
 
- - You have contacted your Shareholder Servicing Agent, if necessary.
 
DO I PAY A SALES CHARGE ON AN EXCHANGE?
 
Generally, you will not pay a sales charge on an exchange. However:
 
- - You will pay a sales charge if you own Fiduciary Class shares of a Fund and
  you want to exchange those shares for Class A shares, unless you qualify for a
  sales charge waiver (see above).
 
- - You will pay a sales charge if you bought Class A shares of a Fund:
 
   1. That does not charge a sales charge and you want to exchange them for
      shares of a Fund that does, in which case you would pay the sales charge
      applicable to the Fund into which you are exchanging.
 
   2. That charged a lower sales charge than the Fund into which you are
      exchanging, in which case you would pay the difference between that Fund's
      sales charge and all other sales charges you have already paid.
 
- - If you exchange Class B or Class C shares of a Fund, you will not pay a sales
  charge at the time of the exchange, however:
 
   1. Your new Class B or Class C shares will be subject to the higher CDSC of
      either the Fund from which you exchanged, the Fund into which you
      exchanged, or any Fund from which you previously exchanged.
 
   2. The current holding period for your exchanged Class B or Class C shares is
      carried over to your new shares.
 
ARE EXCHANGES TAXABLE?
 
Generally:
 
- - An exchange between classes of shares of the same Fund is not taxable.
 
- - An exchange between Funds is considered a sale and generally results in a
  capital gain or loss for Federal income tax purposes.
 
- - You should talk to your tax advisor before making an exchange.
 
ARE THERE LIMITS ON EXCHANGES?
 
Yes. The exchange privilege is not intended as a way for you to speculate on
short-term movements in the market. Therefore:
 
- - To prevent disruptions in the management of the Funds, The One Group limits
  excessive exchange activity.
 
- - Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
  REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH PERIOD.
 
   
- - In addition, The One Group reserves the right to reject any exchange request
  (even those that are not excessive) if the Fund reasonably believes that the
  exchange will result in excessive transaction costs or otherwise adversely
  affect other shareholders.

<PAGE>   225
 
                                                                              21
 
   3. the redemption check is mailed to the shareholder at the record address.
 
- - On the Account Application Form you may elect to have the redemption proceeds
  mailed or wired to:
 
   
   1. a designated commercial bank or
    
 
   2. State Street Bank and Trust Company or your Shareholder Servicing Agent.
 
   
- - State Street Bank and Trust Company may charge you a wire redemption fee. The
  current charge is $7.00.
    
 
- - Your redemption proceeds will be paid within seven days after receipt of the
  redemption request.
 
WHAT WILL MY SHARES BE WORTH?
 
- - If you own Class A and Fiduciary Class shares and the Fund receives your
  redemption request by 4:00 p.m. EST, you will receive that day's NAV.
 
- - If you own Class B and Class C shares and the Fund receives your redemption
  request by 4:00 p.m. EST, you will receive that day's NAV, minus the amount of
  any applicable CDSC.
 
CAN I REDEEM BY TELEPHONE?
 
Yes, if you selected this option on your Account Application Form.
 
- - Call your Shareholder Servicing Agent or State Street Bank and Trust Company
  at 1-800-480-4111 to relay your redemption request.
 
- - Your redemption proceeds will be mailed or wired to the commercial bank
  account you designated on your Account Application Form.
 
- - State Street Bank and Trust Company may charge you a wire redemption fee. The
  current charge is $7.00.
 
- - The One Group uses reasonable procedures to confirm that instructions given by
  telephone are genuine. These procedures include recording telephone
  instructions and asking for personal identification. If these procedures are
  followed, The One Group will not be responsible for any loss, liability, cost
  or expense of acting upon unauthorized or fraudulent instructions; you bear
  the risk of loss.
 
- - REDEMPTIONS FROM YOUR IRA ACCOUNT MAY NOT BE MADE BY TELEPHONE.
 
CAN I REDEEM ON A SYSTEMATIC BASIS?
 
If you have an account value of at least $10,000, you may elect to receive
monthly, quarterly or annual payments of not less than $100 each.
 
- - Select the "Systematic Withdrawal Plan" option on the Account Application
  Form.
 
- - Specify the amount you wish to receive and the frequency of the payments.
 
- - You may designate a person other than yourself as the payee.
 
- - There is no charge for this service.
 
- - If you select this option, please keep in mind that:
 
   1. It may not be in your best interest to buy additional Class A shares while
      participating in a Systematic Withdrawal Plan. This is because Class A
      shares have an up-front sales charge.
 
   2. If you own Class B or Class C shares, you or your designated payee may
      receive systematic payments provided the payments are limited to no more
      than 10% of your account value annually, measured from the date the
      redemption request is received.
 
   3. If you are age 70 1/2, you may elect to receive payments to the extent
      that the payment represents a minimum required distribution from an IRA or
      other qualifying retirement plan.
 
   4. If the amount of the systematic payment exceeds the income earned by your
      account since the previous payment under the Systematic Withdrawal Plan,
      payments will be made by redeeming some of your shares. This will reduce
      the amount of your investment.
 
ADDITIONAL INFORMATION REGARDING REDEMPTIONS
 
- - All redemptions will be for cash.
 
- - If you redeem shares for which you paid by check, and The One Group has not
  yet received payment on the check, The One Group will delay forwarding your
  redemption proceeds for 10 or more days until payment has been collected from
  your bank.
 
- - Because of the high cost of handling small investments, The One Group will
  automatically redeem shares in accounts which, because of shareholder
  redemptions, have values of less than $1,000. No sales charges will be
  assessed and you will be given 60 days to make additional investments in the
  Fund to increase the value of your account to at least $1,000.
 
- - The One Group may suspend your ability to redeem, or will redeem your shares
  involuntarily, when it seems appropriate to do so in light of its
  responsibilities under the Federal securities laws. The Statement of
  Additional Information offers more details about this process.

VOTING RIGHTS
- ----------------------------------------------------
 
The Funds do not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change a Fund's fundamental investment objective, or approve an
investment advisory contract.
 
As a Fund shareholder, you have one vote for each share that you own. Each Fund,
and each class of shares within each Fund, vote separately on matters relating
solely to that Fund or class, or which affect that Fund or class differently.
However, all shareholders will have equal voting rights on matters that affect
all shareholders equally.

BANC ONE CORPORATION (100 East Broad Street, Columbus, Ohio, 43271), through its
affiliates, may be deemed for purposes of the Investment Company Act of 1940, to
control the Funds. This is because as of August 5, 1997, BANC ONE CORPORATION or
its affiliates possessed the power to vote substantially all of the Fiduciary
Class shares of the Funds.
 
On that same date, the following shareholders owned 25% or more of the Class C
shares of the Funds. As a consequence, they are considered to be controlling
persons of Class C shares of the Funds.

DIVIDEND POLICIES
- ----------------------------------------------------
 
DIVIDENDS
 
The Funds generally declare dividends monthly. Dividends are distributed on the
first Business Day of each month. Capital gains, if any, for all Funds are
distributed at least annually.
 
The Funds pay dividends and distributions on a per-share basis. This means that
the value of your shares will be reduced by the amount of the payment. If you
purchase shares shortly before the record date for a dividend or the
distribution of capital gains, you will pay the full price for the shares and
receive some portion of the price back as a taxable dividend or distribution.
 
Dividends payable on Fiduciary Class shares will be more than those payable on
other classes of shares. This is because Class A, Class B and Class C shares
have higher distribution expenses.
 
DIVIDEND REINVESTMENT
 
You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund and class, unless you have
elected to take such payment in cash. The price of the shares is the NAV
determined immediately following the dividend record date. Reinvested dividends
and distributions receive the same tax treatment as dividends and distributions
paid in cash.
 
If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8500, Boston, MA
02266-8500, at least 15 days prior to the distribution. The change is effective
upon receipt by State Street.
 
SPECIAL DIVIDEND RULES FOR CLASS B SHARES
 
Class B shares received as dividends and capital gains distributions will be
accounted for separately. Each time any Class B shares (other than those in the
sub-account) convert to Class A shares, a percentage of the Class B shares in
the sub-account will also convert to Class A shares. (See "Conversion Feature".)

TAX TREATMENT
OF THE FUNDS
- ----------------------------------------------------
 
TAX STATUS OF THE FUND
 
Each Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Funds qualify, as they have in the past, they will
pay no federal income tax on the earnings they distribute to shareholders.
 
TAX TREATMENT
OF SHAREHOLDERS
- ----------------------------------------------------
 
TAXATION OF SHAREHOLDER TRANSACTIONS
 
A sale, exchange, or redemption of shares of the Funds generally will produce
either a taxable gain or a loss. You are responsible for any tax liabilities
generated by your transactions.
 
TAXATION OF DISTRIBUTIONS
 
Dividends you receive from a Fund, whether reinvested or received in cash, will
be taxable to you. Dividends from a Fund's net investment income will be taxable
as ordinary income and dividends from a Fund's long-term capital gains will be
taxable to you as such, regardless of how long you have held the shares.
 
Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid the previous December.
 
TAXATION OF RETIREMENT PLANS
 
Distributions by the Funds to qualified retirement plans will not be taxable.
However, if shares are held by a plan that ceases to qualify for tax-exempt
treatment or by an individual who has received shares as a distribution from a
retirement plan, the distributions will be taxable to the plan or individual as
described in "Taxation of Distributions." If you are considering purchasing
shares with qualified retirement plan assets, you should consult your tax
advisor for a more complete explanation of the Federal, state, local and (if
applicable) foreign tax consequences of making such an investment.
 
TAX INFORMATION
 
The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Funds provide you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Funds or their shareholders.

                    ORGANIZATION AND MANAGEMENT OF THE FUNDS
 
24
 
THE FUNDS
 
Each Fund is a series of The One Group, an open-end management investment
company. The One Group currently consists of 40 separate Funds. Four of the
Funds are described in this prospectus; the other Funds are described in
separate prospectuses. Each Fund described in this prospectus is diversified.
Each Fund is supervised by the Board of Trustees.
 
THE BOARD OF TRUSTEES
 
The Trustees oversee the management and administration of the Funds. The
Trustees are responsible for making major decisions about each Fund's investment
objectives and policies, but delegate the day-to-day administration of the Funds
to the officers of The One Group.
 
THE ADVISOR
 
Banc One Investment Advisors makes the day-to-day investment decisions for the
Funds and continuously reviews, supervises and administers the Funds' investment
programs. Banc One Investment Advisors has served as investment advisor to The
One Group since 1993. Prior to that time, The One Group was advised by
affiliates of Banc One Investment Advisors. In addition to The One Group, Banc
One Investment Advisors serves as investment advisor to other mutual funds and
individual, corporate, charitable and retirement accounts. As of June 30, 1997,
Banc One Investment Advisors, an indirect, wholly-owned subsidiary of BANC ONE
CORPORATION, managed over $47 billion in assets. For the fiscal year ended June
30, 1997, the Funds paid investment advisory fees of .01% of each Fund's average
daily net assets.
 
No single person is responsible for managing the assets of the Funds. Rather,
investment decisions for the Funds are made by committee. Banc One Investment
Advisors also serves as the advisor to the underlying mutual funds, for which it
receives a fee.
 
THE DISTRIBUTOR
 
The One Group Services Company, 3435 Stelzer Road, Columbus, Ohio 43219, a
wholly-owned subsidiary of The BISYS Group, Inc., markets the Funds and
distributes shares through selling brokers, financial institutions, investment
advisors, and other financial representatives.
 
THE ADMINISTRATOR AND SUB-ADMINISTRATOR
 
The One Group Services Company also serves as the Funds' administrator. The One
Group Services Company is responsible for responding to shareholder inquiries
and requests for information, as well as providing regulatory compliance and
reporting. For these services, The One Group Services Company receives an annual
fee of .10% of each Fund's average daily net assets, on the first $500,000,000
in Fund assets. The fee declines to .075% on net assets between $500,000,000 and
$1 billion, and to .05% on assets over $1 billion. The fee is calculated daily
and paid monthly. Banc One Investment Advisors, the Sub-Administrator, provides
office space, equipment, and facilities, as well as legal and regulatory
support.
 
THE TRANSFER AGENT, CUSTODIAN AND SUB-CUSTODIAN
 
State Street Bank and Trust Company, P.O. Box 8500, Boston, MA 02266-8500, or
your Shareholder Servicing Agent, if appropriate, handles shareholder
recordkeeping and statementing, distributes dividends, and processes buy and
sell requests. As the Funds' custodian, State Street holds the Funds' assets,
settles all portfolio trades and assists in calculating the Funds' net asset
values. Bank One Trust Company, N.A. serves as sub-custodian in connection with
The One Group's securities lending activities under an agreement with State
Street Bank and Trust Company. Bank One Trust Company, N.A. is paid a fee for
this service.

           DETAILS ABOUT THE FUNDS' INVESTMENT PRACTICES AND POLICIES
 
                                                                              25
 
INVESTMENT PRACTICES
- ----------------------------------------------------
 
The following is a brief description of the principal investment policies of the
underlying funds.
 
THE ONE GROUP(R) PRIME MONEY MARKET FUND
 
The One Group(R) Prime Money Market Fund seeks current income with liquidity and
stability of principal. The fund intends to comply with the regulations of the
Securities and Exchange Commission applicable to money market funds using the
amortized cost method for calculating net asset value. These regulations impose
certain quality, maturity and diversification restraints on investments by the
fund. Under these regulations, the fund will invest only in U.S.
dollar-denominated securities, will maintain an average maturity on a
dollar-weighted basis of 90 days or less, and will acquire only "eligible
securities" that present minimal credit risks and are treated as having a
maturity of 397 days or less.
 
THE ONE GROUP(R) LIMITED VOLATILITY
BOND FUND
 
The One Group(R) Limited Volatility Bond Fund seeks current income consistent
with preservation of capital through investment in high and medium-grade
fixed-income securities. The Fund normally invests at least 80% of total assets
in debt securities of all types with short to intermediate maturities. Debt
securities include bonds, notes and other obligations. At least 65% of the
Fund's total assets will consist of bonds rated in one of the three highest
investment grade categories at the time of investment, or if unrated, determined
by Banc One Investment Advisors to be of comparable quality, and at least 65% of
total assets will consist of obligations issued by the U.S. government or its
agencies and instrumentalities, some of which may be subject to repurchase
agreements. Many investments will satisfy both requirements. Under normal market
conditions, it is anticipated that the fund's average weighted maturity will
range between one and five years. The fund may also purchase taxable or
tax-exempt municipal securities. Up to 20% of the fund's total assets may be
invested in preferred stocks.
 
THE ONE GROUP(R) INTERMEDIATE BOND FUND
 
The One Group(R) Intermediate Bond Fund seeks current income consistent with the
preservation of capital through investments in high and medium-grade
fixed-income securities with intermediate maturities. The fund will normally
invest at least 80% of total assets in debt securities of all types. Debt
securities include bonds, notes and other obligations. At least 65% of the
fund's total assets will consist of bonds rated in one of the three highest
investment grade categories at the time of investment, or if unrated, determined
by Banc One Investment Advisors to be of comparable quality, and at least 50% of
total assets will consist of obligations issued by the U.S. government or its
agencies and instrumentalities, some of which may be subject to repurchase
agreements. Many investments will satisfy both requirements. The Fund also may
invest in more speculative debt securities if they present attractive
opportunities and are rated in the lowest investment grade category. The fund
may also purchase taxable or tax-exempt municipal securities. Under normal
market conditions, it is anticipated that the fund's average weighted maturity
will range between three and ten years. Up to 20% of the fund's total assets may
be invested in preferred stocks.
 
THE ONE GROUP(R) INCOME BOND FUND
 
The One Group(R) Income Bond Fund seeks a high level of current income by
investing primarily in a diversified portfolio of high, medium and low grade
debt securities. The Fund normally will invest at least 70% of its total assets
in debt securities of all types rated as investment grade at the time of
investment or, if unrated, determined by Banc One Investment Advisors to be of
comparable quality. In addition, up to 30% of the Fund's total assets may be
invested in convertible securities, preferred stock, loan participations and
debt securities rated below investment grade or, if unrated, determined by Banc
One Investment Advisors to be of comparable quality. Securities rated below
investment grade are called "high yield bonds," "non-investment grade bonds" and
"junk bonds." These securities are rated in the fifth or lower rating
categories, for example, BB or lower by Standard & Poor's Corporation ("S&P")
and Ba or lower by Moody's Investors Service, Inc. ("Moody's"), and are
considered to have speculative characteristics. Even though it may invest in
debt securities in all rating categories, the Fund will not invest more than 20%
of its total assets in securities rated below the fifth rating category. As a
matter of fundamental policy, at least 65% of the Fund's total assets will
consist of bonds. The Fund also may purchase taxable or tax-exempt municipal
securities.
<PAGE>   230
26
 
Under normal market conditions, it is anticipated that the Fund's average
weighted maturity will range between five and twenty years. The Fund may shorten
its effective weighted average maturity to as little as two years if deemed
appropriate for temporary defensive purposes.
 
THE ONE GROUP(R) GOVERNMENT BOND FUND
 
The One Group(R) Government Bond Fund seeks a high level of current income with
liquidity and safety of principal. The Fund will limit its investments to
securities issued by the U.S. Government and its agencies and instrumentalities
or related to securities issued by the U.S. Government and its agencies and
instrumentalities. At least 65% of the total assets of the Fund will be invested
in obligations guaranteed as to principal and interest by the U.S. Government or
its agencies and instrumentalities, some of which may be subject to repurchase
agreements, and other securities representing an interest in or collateralized
by mortgages that are issued or guaranteed by the U.S. government, its agencies
or instrumentalities. The average weighted remaining maturity of the fund is
expected to be between three and fifteen years, however, the Fund's average
weighted remaining maturity may be outside this range if warranted by market
conditions. The balance of the Fund's assets may be invested in debt securities
and taxable or tax-exempt municipal securities.
 
THE ONE GROUP(R) ULTRA SHORT-TERM
INCOME FUND
 
The One Group(R) Ultra Short-Term Income Fund seeks a high level of current
income consistent with low volatility of principal by investing in a diversified
portfolio of short-term investment grade securities. The Fund normally invests
at least 80% of its total assets in debt securities of all types, including
money market instruments. In addition, up to 20% of the fund's total assets may
be invested in other securities, including preferred stock. The fund will invest
in adjustable rate mortgage pass-through securities and other securities
representing an interest in or collateralized by mortgages with periodic
interest rate resets, some of which may be subject to repurchase agreements.
These securities often are issued or guaranteed by the U.S. government, its
agencies or instrumentalities. However, the Fund also may purchase
mortgage-backed securities that are issued by non-governmental entities. Such
securities may or may not have private insurer guarantees as to timely payments.
The fund also may purchase mortgage and interest rate swaps and interest rate
floors and caps. The fund also may employ other investment techniques to enhance
returns, such as loans of fund securities, mortgage dollar rolls, repurchase
agreements, options contracts and reverse repurchase agreements. The Fund will
maintain a maximum duration of approximately two years.
 
THE ONE GROUP(R) DISCIPLINED VALUE FUND
 
The One Group(R) Disciplined Value Fund seeks capital appreciation with the
secondary goal of achieving current income by investing primarily in equity
securities. The Fund will invest mainly in equity securities with below-market
average price-to-earnings and price-to-book value ratios. The issuer's soundness
and earnings prospects also will be considered. If Banc One Investment Advisors
determines that a company's fundamentals are declining or that the company's
ability to pay dividends has been impaired, it likely will eliminate the Fund's
holding of the company's stock. The Fund normally invests at least 80% of the
value of its total assets in equity securities consisting of common stocks and
debt securities and preferred stocks that are convertible into common stocks.
The fund also may enter into options and futures transactions. The balance of
the fund's assets will be held in cash equivalents.
 
THE ONE GROUP(R) INTERNATIONAL
EQUITY INDEX FUND
 
The One Group(R) International Equity Index Fund seeks to provide investment
results that correspond to the aggregate price and dividend performance of the
securities in the Gross Domestic Product Weighted Morgan Stanley Capital
International Europe, Australia and Far East Index ("MSCI EAFE GDP Index" or
"EAFE GDP Index").(1) The Fund normally will invest at least 65% of the value
of its total assets in foreign equity securities, which are representative of
the Index and secondarily in stock index futures. The Fund's investments will
consist of common stocks (including sponsored and unsponsored American
Depository Receipts) and preferred stocks, securities convertible into common
stocks (only if they are listed on registered exchanges or actively traded in
the over-the-counter market), warrants and depository receipts. No more than 10%
of the fund's net assets will be held in cash or cash equivalents. The fund may
invest up

to 10% ofits net assets in securities of emerging international markets. A
substantial portion of the fund's assets will be denominated in foreign
currencies.
 
THE ONE GROUP(R) LARGE COMPANY
GROWTH FUND
 
The One Group(R) Large Company Growth Fund seeks long-term capital appreciation
and growth of income by investing primarily in equity securities. The Fund will
normally invest at least 65%, of the value of its total assets in equity
securities consisting of common stocks, warrants and any rights to purchase
common stocks. To achieve its objective, the Fund will invest primarily in
equity securities of large, well established companies with weighted average
capitalization in excess of the market median capitalization of the Standard &
Poor's 500 Composite Stock Price Index ("S&P 500 Index").(2) The fund may
invest the remainder of its assets in any combination of nonconvertible fixed
income securities, repurchase agreements, options and futures contracts,
securities issued by the U.S. government and its agencies and instrumentalities,
and cash equivalents.
 
THE ONE GROUP(R) LARGE COMPANY
VALUE FUND
 
The One Group(R) Large Company Value Fund seeks capital appreciation with the
incidental goal of achieving current income by investing primarily in equity
securities. The Fund will invest in equity securities of large capitalization
companies that are believed to be selling below their long-term investment
values. The average weighted market capitalization of the companies in which the
Fund invests will normally exceed the median market capitalization of the S&P
500 Index. In addition, the Fund may invest in stock of companies which have
"breakup" values well in excess of current market values or which have uniquely
undervalued corporate assets. The Fund normally will invest at least 80% of the
value of its total assets in equity securities consisting of common stocks and
debt securities and preferred stocks which are convertible into common stocks.
The remainder of the fund's assets will be held in cash equivalents
 
THE ONE GROUP(R) GROWTH OPPORTUNITIES FUND
 
The One Group(R) Growth Opportunities Fund seeks growth of capital and,
secondarily, current income by investing primarily in equity securities. The
Fund invests in securities that have the potential to produce above-average
earnings growth per share over a one-to-three year period. Typically, the Fund
acquires shares of established companies with a history of above-average growth,
as well as those companies expected to enter periods of above-average growth.
Not all the securities purchased by the Fund will pay dividends. The Fund also
invests in smaller companies in emerging growth industries. At least 80% of the
value of its total assets will be invested in equity securities consisting of
common stocks and debt securities and preferred stocks that are convertible into
common stocks. The fund also may enter into options and futures transactions.
The remainder of the fund's assets will be held in cash equivalents.
 
THE ONE GROUP(R) VALUE GROWTH FUND
 
The One Group(R) Value Growth Fund seeks long-term capital growth and growth of
income with a secondary objective of providing a moderate level of current
income. The Fund invests primarily in common stocks, debt securities, preferred
stocks, convertible securities, warrants, and other equity securities of
overlooked or undervalued companies that show the potential for growth of
earnings over time. Although the Fund expects to invest in securities that pay a
moderate level of income, it may also invest in non-income producing securities.
The Fund normally will invest at least 65% of the value of its total assets in
securities with the characteristics described above. Although the fund intends
to invest all of its assets in such securities, up to 35% of its total assets
may be held in cash or invested in U.S. Government Securities, other investment
grade fixed-income securities cash and cash equivalents.
 
THE ONE GROUP(R) SMALL CAPITALIZATION FUND
 
The One Group(R) Small Capitalization Fund seeks long-term capital growth
primarily by investing in a portfolio of equity securities of
small-capitalization and emerging growth companies. The Fund invests primarily
in a portfolio of common stocks, debt securities, preferred stocks, convertible
securities, warrants and other equity securities of small capitalization
companies. Generally, Banc One Investment Advisors selects a portfolio of
companies with a capitalization equivalent to the median market capitalization
of the S&P Small-Cap 600 Index(3), although the Fund may occasionally hold
securities of companies whose market capitaliza-

tions are considerably larger if doing so contributes to the funds investment
objective. At least 65% of the value of the Fund's total assets normally will be
invested in securities with the characteristics described above. Up to 35% of
its total assets may be held in cash or invested in U.S. Government Securities,
other investment grade fixed-income securities and cash equivalents.
 
THE ONE GROUP(R) INCOME EQUITY FUND
 
The One Group(R) Income Equity Fund seeks current income through regular payment
of dividends with the secondary goal of achieving capital appreciation by
investing primarily in equity securities. The Fund attempts to keep its yield
above the S&P 500 Index by investing in common stocks of corporations which
regularly pay dividends, although continued payment of dividends cannot be
assured. The fund will invest primarily in stocks with favorable, long-term
fundamental characteristics, but stocks of companies that are out of favor in
the financial community also may be purchased. The Fund normally invests at
least 80% of the value of its total assets in equity securities consisting of
common stocks, and debt securities and preferred stocks which are convertible
into common stocks. The Fund also may enter into options and futures
transactions. The balance of the Fund's assets will be held in cash equivalents.
 
THE ONE GROUP(R) EQUITY INDEX FUND
 
The One Group(R) Equity Index Fund seeks investment results that correspond to
the aggregate price and dividend performance of the securities in the S&P 500
Index. The Fund normally invests in many of the stocks which comprise the S&P
500 Index and secondarily in stock index futures. Cash reserves will not
normally exceed 10% of the fund's net assets. The Advisor generally selects
stocks for the Fund in the order of their weightings in the S&P 500 Index
beginning with the heaviest weighted stocks. The percentage of the Fund's assets
to be invested in each stock is approximately the same as the percentage it
represents in the S&P 500 Index.
 
   
Details about each underlying fund's investment practices and the risks
associated with those practices can be found in Appendix B.
    
 
INVESTMENT POLICIES
- ----------------------------------------------------
 
Each Fund's investment objective and the investment policies summarized below
are fundamental. This means that they cannot be changed without the consent of a
majority of the outstanding shares of the Funds. The full text of the
fundamental policies can be found in the Statement of Additional Information.
 
Each Fund may not:
 
   
1. Purchase an issuer's securities if as a result more then 5% of its total
   assets would be invested in the securities of that issuer or the Fund would
   own more than 10% of the outstanding voting securities of any of that issuer.
   This does not include securities issued or guaranteed by the United States,
   its agencies or instrumentalities, securities of other registered investment
   companies and repurchase agreements involving these securities. This
   restriction applies with respect to 75% of a Fund's total assets.
    
 
2. Concentrate its investments in the securities of one or more issuers
   conducting their principal business in a particular industry or group of
   industries. This does not include obligations issued or guaranteed by the
   U.S. government or its agencies and instrumentalities and repurchase
   agreements involving such securities.
 
3. Make loans, except that a Fund may (i) purchase or hold debt instruments in
   accordance with its investment objective and policies; (ii) enter into
   repurchase agreements; and (iii) engage in securities lending.
 
Additional investment policies can be found in the Statement of Additional
Information.
 
PORTFOLIO TURNOVER
 
Portfolio turnover may vary greatly from year to year as well as within a
particular year. Higher portfolio turnover rates will likely result in higher
transaction costs to the Funds and may result in additional tax consequences to
you. The portfolio turnover rate for each Fund for the fiscal year ended June
30, 1997 is shown on the Financial Highlights.

INVESTMENT RISKS
- ----------------------------------------------------
 
Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities held by the underlying funds may fluctuate, as will the
value of the Fund's investments in the underlying funds. Ultimately, the value
of your investment will be affected. Certain investments are more susceptible to
these risks than others.
 
- - CREDIT RISK. The risk that the issuer of a security, or the counterparty to a
  contract, will default or otherwise become unable to honor a financial
  obligation. Credit risk is generally higher for non-investment grade
  securities. The price of a security can be adversely affected prior to actual
  default as its credit status deteriorates and the probability of default
  rises.
 
   
- - LEVERAGE RISK. The risk associated with securities or practices that multiply
  small index or market movements into large changes in value. Leverage is often
  associated with investments in derivatives, but also may be embedded directly
  in the characteristics of other securities.
    
 
   - HEDGED. When a derivative (a security whose value is based on another
     security or index) is used as a hedge against an opposite position that the
     fund also holds, any loss generated by the derivative should be
     substantially offset by gains on the hedged investment, and vice versa.
     While hedging can reduce or eliminate losses, it can also reduce or
     eliminate gains. Hedges are sometimes subject to imperfect matching between
     the derivative and underlying security, and there can be no assurance that
     a Fund's hedging transactions will be effective.
 
   - SPECULATIVE. To the extent that a derivative is not used as a hedge, the
     fund is directly exposed to the risks of that derivative. Gains or losses
     from speculative positions in a derivative may be substantially greater
     than the derivative's original cost.
 
- - LIQUIDITY RISK. The risk that certain securities may be difficult or
  impossible to sell at the time and the price that normally prevails in the
  market. The seller may have to lower the price, sell other securities instead
  or forego an investment opportunity, any of which could have a negative effect
  on fund management or performance. This includes the risk of missing out on an
  investment opportunity because the assets necessary to take advantage of it
  are tied up in less advantageous investments.
 
- - MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
  to produce the intended result. This includes the risk that changes in the
  value of a hedging instrument will not match those of the asset being hedged.
  Incomplete matching can result in unanticipated risks.
 
- - MARKET RISK. The risk that the market value of a security may move up and
  down, sometimes rapidly and unpredictably. These fluctuations may cause a
  security to be worth less than the price originally paid for it, or less than
  it was worth at an earlier time. Market risk may affect a single issuer,
  industry, sector of the economy or the market as a whole. There is also the
  risk that the current interest rate may not accurately reflect existing market
  rates. For fixed income securities, market risk is largely, but not
  exclusively, influenced by changes in interest rates. A rise in interest rates
  typically causes a fall in values, while a fall in rates typically causes a
  rise in values. Finally, key information about a security or market may be
  inaccurate or unavailable. This is particularly relevant to investments in
  foreign securities.
 
- - POLITICAL RISK. The risk of losses attributable to unfavorable governmental or
  political actions, seizures of foreign deposits, changes in tax or trade
  statutes, and governmental collapse and war.
 
- - FOREIGN INVESTMENT RISK. The risk associated with higher transaction costs,
  delayed settlements, currency controls and adverse economic developments. This
  also includes the risk that fluctuations in the exchange rates between the
  U.S. dollar and foreign currencies may negatively affect an investment.
  Adverse changes in exchange rates may erode or reverse any gains produced by
  foreign currency denominated investments and may widen any losses. Exchange
  rate volatility also may affect the ability of an issuer to repay U.S. dollar
  denominated debt, thereby increasing credit risk.
 
- - PRE-PAYMENT RISK. The risk that the principal repayment of a security will
  occur at an unexpected time, especially that the repayment of a mortgage or
  asset-backed security occurs either significantly sooner or later than
  expected. Changes in pre-payment rates can result in
<PAGE>   237
 
                                                                              33
 
  greater price and yield volatility. Pre-payments generally accelerate when
  interest rates decline. When mortgage and other obligations are pre-paid, a
  Fund may have to reinvest in securities with a lower yield. Further, with
  early prepayment, a Fund may fail to recover any premium paid, resulting in an
  unexpected capital loss.
 
- - TAX RISK. The risk that the issuer of the securities will fail to comply with
  certain requirements of the Internal Revenue Code, which would cause adverse
  tax consequences.
 
- - REGULATORY RISK. The risk associated with Federal and state laws which may
  restrict the remedies that a mortgage lender has when a borrower defaults on
  mortgage loans. These laws include restrictions on foreclosures, redemption
  rights after foreclosure, Federal and state bankruptcy and debtor relief laws,
  restrictions on "due on sale" clauses, and state usury laws.

DESCRIPTION OF RATINGS
 
The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.
 
Unrated securities will be treated as non-investment grade securities unless
Banc One Investment Advisors determines that such securities are the equivalent
of investment grade securities. Securities that have received different ratings
from more than one agency are considered investment grade if at least one agency
has rated the security investment grade.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
 
DUFF & PHELPS CREDIT RATING CO. ("DUFF")
 
    D-1+ Highest certainty of timely payment. Short-term liquidity, including
         internal operating factors and/or access to alternative sources of
         funds, is outstanding and safety is just below risk-free U.S. Treasury
         obligations.
 
     D-1 Very high certainty of timely payment. Liquidity factors are excellent
         and supported by good fundamental protection factors. Risk factors are
         minor.
 
    D-1- High certainty of timely payment. Liquidity factors are strong and
         supported by good fundamental protection factors. Risk factors are very
         small.
 
STANDARD & POOR'S CORPORATION ("S&P")
 
     A-1 Highest category of commercial paper. Capacity to meet financial
         commitment is strong. Obligations designated with a plus sign (+)
         indicate that capacity to meet financial commitment is extremely
         strong.
 
     A-2 Issues somewhat more susceptible to adverse effects of changes in
         circumstances and economic conditions than obligations in higher rating
         categories. However, the capacity to meet financial commitments is
         satisfactory.
 
FITCH'S INVESTORS SERVICE, L.P. ("FITCH")
 
    F-1+ Exceptionally strong credit quality. Strongest degree of assurance for
         timely payment.
 
     F-1 Very strong credit quality. Assurance of timely payment is only
         slightly less in degree than issues rated F-1+.
 
     F-2 Good credit quality. Satisfactory degree of assurance for timely
         payment, but the margin of safety is not as good as for issues assigned
         F-1+ and F-1 ratings.
 
IBCA LIMITED ("IBCA")
 
      A1 Highest capacity for timely repayment. Those issues rated A1+ possess a
         particularly strong credit feature.
 
      A2 Satisfactory capacity for timely repayment although such capacity may
         be susceptible to adverse changes in business, economic or financial
         conditions.
 
MOODY'S INVESTORS SERVICE ("MOODY'S")
 
 PRIME-1 Superior ability for repayment.
 
 PRIME-2 Strong ability for repayment.
 
DESCRIPTION OF BANK RATINGS
 
MOODY'S
 
These ratings represent Moody's opinion of a bank's intrinsic safety and
soundness.
 
       A These banks possess exceptional intrinsic financial strength. Typically
         they will be major financial institutions with highly valuable and
         defensible business franchises, strong financial fundamentals, and a
         very attractive and stable operating environment.
 
       B These banks possess strong intrinsic financial strength. Typically,
         they will be important institutions with valuable and defensible
         business franchises, good financial fundamentals, and an attractive and
         stable operating environment.
 
       C These banks possess good intrinsic financial strength. Typically, they
         will be institutions with valuable and defensible business franchises.
         These banks will demonstrate either acceptable financial fundamentals
         within a stable operating environment, or better than average financial
         fundamentals within an unstable operating environment.

S&P
 
S&P's credit rating is a current opinion of an obligor's overall financial
capacity (its creditworthiness) to pay its financial obligation.
 
    AAA The highest rating assigned by S&P. The obligor's capacity to meet its
        financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
      A The obligation is somewhat more susceptible to the adverse effects of
        changes in circumstances and economic conditions than obligations in
        higher rated categories. However, the obligor's capacity to meet its
        financial commitment on the obligation is still strong.
 
DESCRIPTION OF INSURANCE RATINGS
 
MOODY'S
 
These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.
 
    Aaa Insurance companies rated in this category offer exceptional financial
        security. While the financial strength of these companies is likely to
        change, such changes as can be visualized are most unlikely to impair
        their fundamentally strong position.
 
      Aa These insurance companies offer excellent financial security. 
         Together with the Aaa group, they constitute what are generally 
         known as high grade companies. They are rated lower than Aaa 
         companies because long-term risks appear somewhat larger.
 
       A Insurance companies rated in this category offer good financial
         security. However, elements may be present which suggest a
         susceptibility to impairment sometime in the future.
 
S&P
 
S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.
 
    AAA This is the highest rating assigned by S&P. The obligor's capacity to
        meet its financial commitment on the obligation is extremely strong.
 
     AA The obligor's capacity to meet its financial commitments on the
        obligation is very strong.
 
      A An obligation rated A is somewhat more susceptible to the adverse
        effects of changes in circumstances and economic conditions than
        obligations in higher rated categories. However, the obligor's 
        capacity to meet its financial commitment on the obligation is still 
        strong.
 
DESCRIPTION OF CORPORATE/ MUNICIPAL BOND RATINGS
 
S&P
 
Investment Grade
 
    AAA The highest rating. The rating indicates an extremely strong capacity 
        to meet its financial commitment.
 
     AA Differs from AAA issues only in a small degree. The obligor's capacity
        to meet its financial commitment is very strong.
 
      A These bonds are somewhat more susceptible to the adverse effects of
        changes in circumstances and economic conditions than debt in higher
        rated categories. However, capacity to meet its financial commitment 
        on the obligation is still strong.
 
    BBB Exhibits adequate protection parameters. However, adverse economic
        conditions or changing circumstances are more likely to lead to a
        weakened capacity to meet its financial commitment on the obligation.
 
Speculative Grade
 
     BB Less vulnerable to non-payment than other speculative issues. However,
        these bonds face major ongoing uncertainties or exposure to adverse
        business, financial or economic conditions which could lead to
        inadequate capacity to meet financial commitment on the obligation.
 
      B More vulnerable to non-payment than obligations rated BB, but 
        currently has the capacity to meet its financial commitment on the 
        obligation. Adverse business, financial or economic conditions will 
        likely impair capacity or willingness to meet its financial 
        commitment on the obligation.
 
    CCC Currently vulnerable to non-payment, and is dependent upon favorable
        business, financial, and economic conditions to meet its financial
        commitment on the obligation. In the event of adverse busi-
<PAGE>   240
 36
        ness, financial, or economic conditions, they are not likely to have 
        the capacity to meet its financial commitment on the obligation.
 
     CC Currently highly vulnerable to non-payment.
 
      C This rating may be used to cover a situation where a bankruptcy
        petition has been filed, or similar action has been taken, but 
        payments on this obligation are being continued.
 
      D Bonds in payment default.
 
Ratings from AA to CCC may be modified by a plus (+) or minus (-) to show
relative standing within the major rating categories.
 
MOODY'S
 
Investment Grade
 
    Aaa Best quality. They carry the smallest degree of investment risk and 
        are generally referred to as "gilt edged." Interest payments are 
        protected by a large, or an exceptionally stable, margin and 
        principal is secure.
 
     Aa High quality by all standards. Margins of protection may not be as
        large as in Aaa securities, fluctuation of protective elements may be
        greater, or there may be other elements present that make the 
        long-term risks appear somewhat larger than in Aaa securities.
 
      A These bonds possess many favorable investment attributes and are to be
        considered as upper-medium grade obligations. Factors giving security
        to principal and interest are considered adequate, but elements may be
        present which suggest a susceptibility to impairment sometime in the
        future.
 
    Baa These bonds are considered medium-grade obligations (i.e., they are
        neither highly protected nor poorly secured). Interest payments and
        principal security appear adequate for the present but certain
        protective elements may be lacking or may be characteristically
        unreliable over any great length of time. Such bonds lack outstanding
        investment characteristics and in fact have speculative characteristics
        as well.
 
Non-Investment Grade
 
     Ba These bonds have speculative elements; their future cannot be
        considered as well assured. The protection of interest and principal
        payments may be very moderate and thereby not well safeguarded during
        good and bad times over the future.
 
      B These bonds lack the characteristics of a desirable investment (i.e.,
        potentially low assurance of timely interest and principal payments or
        maintenance of other contract terms over any long period of time may 
        be small).
 
    Caa Bonds in this category have poor standing and may be in default. 
        These bonds carry an element of danger with respect to principal and 
        interest payments.
 
     Ca Speculative to a high degree and could be in default or have other
        marked shortcomings. Ca is the lowest rating.
 
DESCRIPTION OF MUNICIPAL NOTE RATINGS
 
MOODY'S

 MIG1 & Short-term municipal securities rated MIG1 or VMIG1 are of the best
  VMIG1 quality. They have strong protection from established cash flows,
        superior liquidity support or demonstrated broad-based access to the
        market for refinancing.
          
 MIG2 & 
  VMIG2 These Short-term municipal securities rated MIG2 or VMIG2 are of high
        quality. Margins of protection are ample although not so large as in
        the preceding group.

 MIG3 & Favorable quality. All security elements are accounted for, but the
  VMIG3 undeniable strength of the preceding grades is lacking. Liquidity and
        cash flow protection may be narrow and marketing access for
        refinancing is likely to be less well established.
  
 S&P
 
An S&P note rating reflects the liquidity concerns and market access risks
unique to notes. Notes due in three years or less will likely receive a note
rating. Notes maturing beyond three years will most likely receive a long-term
debt rating.
 
   SP-1 Strong capacity to pay principal and interest. Those issues determined
        to possess overwhelming safety characteristics will be given a 
        plus (+) designation.
 
   SP-2 Satisfactory capacity to pay principal and interest.
 
   SP-3 Speculative capacity to pay principal and interest.
 
DESCRIPTION OF PREFERRED STOCK RATINGS
 
MOODY'S

    aaa Top-quality preferred stock. This rating indicates good asset
        protection and the
          
          
<PAGE>   241
 
                                                                            37
 
         least risk of dividend impairment within the universe of preferred
         stocks.
 
      aa High-grade preferred stock. This rating indicates that there is a
         reasonable assurance the earnings and asset protection will remain
         relatively well maintained in the foreseeable future.
 
       a Upper-medium grade preferred stock. While risks are judged to be
         somewhat greater than in the "aaa" and "aa" classification, earnings
         and asset protection are, nevertheless, expected to be maintained at
         adequate levels.
 
     baa Medium-grade preferred stock, neither highly protected nor poorly
         secured. Earnings and asset protection appear adequate at present but
         may be questionable over any great length of time.
 
S&P
 
S&P's preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations.
 
     AAA Highest rating. This rating indicates an extremely strong capacity to
         pay the preferred stock obligations.
 
      AA High-quality, fixed-income security. The capacity to pay preferred 
         stock obligations is very strong, although not as overwhelming as 
         for issues rated "AAA."
 
       A Backed by a sound capacity to pay the preferred stock obligations,
         although it is somewhat more susceptible to the adverse effects of
         changes in circumstances and economic conditions.
 
     BBB Backed by an adequate capacity to pay the preferred stock 
         obligations. Whereas the issuer normally exhibits adequate protection
         parameters, adverse economic conditions or changing circumstances 
         are more likely to lead to a weakened capacity to make payments for 
         a preferred stock in this category than for issues in the "A" 
         category.
 
SHORT-TERM DEBT RATINGS
 
Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.
 
   TBW-1 Very high degree of likelihood that principal and interest will be 
         paid on a timely basis.
 
   TBW-2 While degree of safety regarding timely repayment of principal and
         interest is strong, the relative degree is not as high as for issues
         rated TBW-1.
 
   TBW-3 Lowest investment grade category. While more susceptible to adverse
         developments than obligations with higher ratings, capacity to 
         service principal and interest in a timely fashion is considered 
         adequate.
 
   TBW-4 Non-investment grade and, therefore, speculative.

                       INVESTMENT OBJECTIVES AND POLICIES

         The following policies supplement each Fund's investment objective and
policies as set forth in the respective Prospectus for that Fund.

ADDITIONAL INFORMATION ON FUND INSTRUMENTS

HIGH QUALITY INVESTMENTS WITH REGARD TO THE MONEY MARKET AND INSTITUTIONAL MONEY
MARKET FUNDS

         The Money Market and Institutional Money Market Funds, may invest only
in obligations determined by the Fund's investment Advisor, Banc One Investment
Advisors Corporation ("Banc One Advisors") to present minimal credit risks under
guidelines adopted by the Trust's Board of Trustees.

         The Treasury Money Market Fund and the Treasury Only Money Market Fund
may only invest in U.S. Treasury bills, notes and other U.S. Treasury
obligations issued or guaranteed by the U.S. government. Some of the securities
held by the Treasury Money Market Fund may be subject to repurchase agreements.


         The Government Money Market Fund invests exclusively in securities
issued or guaranteed by the U.S. government or its agencies or
instrumentalities, some of which may be subject to repurchase agreements.

         The Tax Exempt Money Market Fund may invest only in obligations which,
at the time of purchase, (i) possess the highest short-term ratings from a
nationally recognized statistical rating organization (an "NRSRO") in the case
of single-rated securities; or (ii) possess, in the case of multiple-rated
securities, the highest short-term ratings by at least two NRSROs; or (iii) do
not possess a rating (i.e., are unrated) but are determined by Banc One Advisors
to be of comparable quality to the rated instruments eligible for purchase by
the Fund under guidelines adopted by the Board of Trustees (collectively, "First
Tier Securities"). Some of the securities of the Tax Exempt Money Market Fund
may be subject to repurchase agreements.

         With regard to the Money Market Funds and the Institutional Money
Market Funds other than the Tax Exempt Money Market Fund, investments will be
limited to those obligations which, at the time of purchase, (i) possess one of
the two highest short-term ratings from an NRSRO in the case of single-rated
securities; or (ii) possess, in the case of multiple-rated securities, one of
the two highest short-term ratings by at least two NRSROs or (iii) do not
possess a rating (i.e., are unrated) but are determined by Banc One Advisors to
be of comparable quality to the rated instruments eligible for purchase by the
Trust under guidelines adopted by the Board of Trustees (collectively, "Eligible
Securities"). A security that has not received a rating will be deemed to
possess the rating assigned to an outstanding class of the issuer's short-term
debt obligations if determined by Banc One Advisors to be comparable in priority
and security to the obligation selected for purchase by the Trust.

         A security subject to a tender or demand feature will be considered an
Eligible Security only if both the demand feature and the underlying security
possess a high quality rating or, if such do not possess a rating, are
determined by Banc One Advisers to be of comparable quality; provided, however,
that where the demand feature would be readily exercisable in the event of a
default in payment of principal or interest on the underlying security, the
obligation may be acquired based on the rating possessed by the demand feature
or, if the demand feature does not possess a rating, a determination of
comparable quality by Banc One Advisors. A security which at the time of
issuance had a maturity exceeding 397 days but, at the time of purchase, has a
remaining maturity of 397 days or less, is not considered an Eligible Security
if it does not possess a high quality rating and the long-term rating, if any,
is not within the two highest rating categories.

         Eligible Securities include First-Tier Securities and Second-Tier
Securities. First-Tier Securities include those that possess a rating in the
highest category, in the case of a single-rated security, or at least two
ratings in the highest rating category, in the case of multiple-rated
securities, or, if the securities do not possess a rating, are determined to be
of comparable quality by Banc One Advisors pursuant to the guidelines adopted by
the Board of Trustees. Second-Tier Securities are all other Eligible Securities.

         Each Money Market and Institutional Money Market Fund other than the
Ohio Municipal Money Market, the Municipal Money Market and the Tax Exempt Money
Market Funds will not invest more than 5% of its total assets in the First Tier
Securities of any one issuer. In addition, each Fund other than the Municipal
Money Market Fund, the Ohio Municipal Money Market Fund, and the Tax Exempt
Money Market Fund may not invest more than 5% of its total assets in Second Tier
Securities, with investment in the Second Tier Securities of any one issuer
further limited to the greater of 1% of the Fund's total assets or $1.0 million.
If a percentage limitation is satisfied at the time of purchase, a later
increase in such percentage resulting from a change in the Fund's net asset
value or a subsequent change in a security's qualification as a First Tier or
Second Tier Security will not constitute a violation of the limitation. In
addition, there is no limit on the percentage of a Fund's assets that may be
invested in obligations issued or guaranteed by the U.S. government, its
agencies,


                                       2
<PAGE>   248
or instrumentalities and, with respect to each Money Market Fund and each
Institutional Money Market Fund other than the Treasury Only Money Market Fund,
repurchase agreements fully collateralized by such obligations.

         Under the guidelines adopted by the Trust's Board of Trustees and in
accordance with Rule 2a-7 under the 1940 Act, Banc One Advisors may be required
to promptly dispose of an obligation held in a Fund's portfolio in the event of
certain developments that indicate a diminishment of the instrument's credit
quality, such as where an NRSRO downgrades an obligation below the second
highest rating category, or in the event of a default relating to the financial
condition of the issuer.

         A rating by an NRSRO may be utilized only where the NRSRO is neither
controlling, controlled by, or under common control with the issuer of, or any
issuer, guarantor, or provider of credit support for, the instrument.

BANK OBLIGATIONS

         Bank obligations consist of bankers' acceptances, certificates of
deposit, and demand and time deposits.

         Bankers' acceptances are negotiable drafts or bills of exchange
typically drawn by an importer or exporter to pay for specific merchandise,
which are "accepted" by a bank, meaning, in effect, that the bank
unconditionally agrees to pay the face value of the instrument on maturity.
Bankers' acceptances invested in by the Funds will be those guaranteed by
domestic and foreign banks and savings and loan associations having, at the time
of investment, total assets in excess of $1 billion (as of the date of their
most recently published financial statements).

         Certificates of deposit are negotiable certificates issued against
funds deposited in a commercial bank or a savings and loan association for a
definite period of time and earning a specified return. Certificates of deposit
will be those of domestic and foreign branches of U.S. commercial banks which
are members of the Federal Reserve System or the deposits of which are insured
by the Federal Deposit Insurance Corporation, and in certificates of deposit of
domestic savings and loan associations the deposits of which are insured by the
Federal Deposit Insurance Corporation if, at the time of purchase, such
institutions have total assets in excess of $1 billion (as of the date of their
most recently published financial statements). Certificates of deposit may also
include those issued by foreign banks outside the United States with total
assets at the time of purchase in excess of the equivalent of $1 billion. The
Funds may also invest in Eurodollar certificates of deposit, which are U.S.
dollar-denominated certificates of deposit issued by branches of foreign and
domestic banks located outside the United States, and Yankee certificates of
deposit, which are certificates of deposit issued by a U.S. branch of a foreign
bank denominated in U.S. dollars and held in the United States. The
International Equity Index Fund may also invest in obligations (including
banker's acceptances and certificates of deposit) denominated in foreign
currencies (see "Foreign Investments" herein).

         Time deposits are interest-bearing non-negotiable deposits at a bank or
a savings and loan association that have a specific maturity date. A time
deposit earns a specific rate of interest over a definite period of time. Time
deposits cannot be traded on the secondary market and those exceeding seven days
and with a withdrawal penalty are considered to be illiquid. Demand deposits are
funds deposited in a commercial bank or a savings and loan association which,
without prior notice to the bank, may be withdrawn generally by negotiable
draft. Time and demand deposits will be maintained only at banks or savings and
loan associations from which a Fund could purchase certificates of deposit.

COMMERCIAL PAPER

         Commercial paper consists of secured and unsecured promissory notes
issued by corporations. Except as noted below with respect to variable amount
master demand notes, issues of commercial paper normally have maturities of less
than nine months and fixed rates of return.

         The Limited Volatility Bond Fund may purchase commercial paper
consisting of issues rated at the time of purchase in the highest rating
category by at least one NRSRO (such as A-1 by Standard & Poor's Corporation
("S&P"), P-1 by Moody's Investors Service, Inc. ("Moody's") or F-1 by Fitch
Investors Service, L.P. ("Fitch")) or if unrated, determined by Banc One
Advisors to be of comparable quality. The Money Market Funds (other than the
U.S. Treasury Securities Money Market Fund), the Asset Allocation Fund, the
Equity Funds other than the International Equity Index Fund, the Municipal Bond
Funds, the Income Bond Fund, the Intermediate Bond Fund, and the Ultra
Short-Term Income Fund may purchase commercial paper consisting of issues rated
at the time of purchase in the highest or second highest rating category by at
least one NRSRO (such as A-2 or better by S&P, P-2 or better by Moody's or F-2
or better by Fitch) or if unrated, determined by Banc One Advisors to be of
comparable quality. The Income Fund may purchase commercial paper consisting of
issues rated at the time of purchase in all rating categories by at least one
NRSRO, or, if unrated, determined by Banc One Advisors to be of comparable
quality.

REPURCHASE AGREEMENTS

         Under the terms of a repurchase agreement, a Fund would acquire
securities from member banks of the Federal Deposit Insurance Corporation (or in
the case of the International Equity Index Fund, such banks or foreign banks)
with total assets in excess of $1 billion (or in the case of the International
Equity Index Fund, the equivalent of $1 billion) and registered broker-dealers
(or in the case of the International Equity Index Fund, broker-dealers which may
or may not be registered) which Banc One Advisors deems creditworthy under
guidelines approved by the Board of Trustees, subject to the seller's agreement
to repurchase such securities at a mutually agreed-upon date and price. The
repurchase price would generally equal the price paid by the Fund plus interest
negotiated on the basis of current short-term rates, which may be more or less
than the rate on the underlying portfolio securities. The seller under a
repurchase agreement will be required to maintain the value of collateral held
pursuant to the agreement at not less than the repurchase price (including
accrued interest). If the seller were to default on its repurchase obligation or
become insolvent, the Fund holding such obligation would suffer a loss to the
extent that the proceeds from a sale of the underlying portfolio securities were
less than the repurchase price under the agreement, or to the extent that the
disposition of such securities by the Fund were delayed pending court action.
Additionally, there is no controlling legal precedent under U.S. law and there
may be no controlling legal precedents under the laws of certain foreign
jurisdictions confirming that a Fund would be entitled, as against a claim by
such seller or its receiver or trustee in bankruptcy, to retain the underlying
securities, although (with respect to repurchase agreements subject to U.S. law)
the Board of Trustees of the Trust believes that, under the regular procedures
normally in effect for custody of a Fund's securities subject to repurchase
agreements and under federal laws, a court of competent jurisdiction would rule
in favor of the Trust if presented with the question. Securities subject to
repurchase agreements will be held by the Trust's custodian or another qualified
custodian or in the Federal Reserve/Treasury book-entry system. Although there
is no current intention to do so, the International Equity Index Fund reserves
the right in the future to enter into repurchase agreements. Repurchase
agreements are considered by the Securities and Exchange Commission to be loans
by a Fund under the 1940 Act.

REVERSE REPURCHASE AGREEMENTS

         Funds may borrow money for temporary purposes by entering into reverse
repurchase agreements. Pursuant to such agreements, a Fund would sell portfolio
securities to financial institutions such as banks and broker-dealers, and agree
to repurchase them at a mutually agreed-upon date and price. A Fund would enter
into reverse repurchase agreements only to avoid otherwise selling securities
during unfavorable market conditions to meet redemptions. At the time a Fund
entered into a reverse repurchase agreement, it would place in a segregated
custodial account assets, such as cash or liquid securities consistent with the
Fund's investment restrictions and having a value equal to the repurchase price
(including accrued interest), and would subsequently monitor the account to
ensure that such equivalent value was maintained. Reverse repurchase agreements
involve the risk that the market value of the securities sold by a Fund may
decline below the price at which the Fund is obligated to repurchase the
securities. Reverse repurchase agreements are considered by the Securities and
Exchange Commission to be borrowings by a Fund under the 1940 Act.

GOVERNMENT SECURITIES

         Obligations of certain agencies and instrumentalities of the U.S.
government, such as the Government National Mortgage Association (Ginnie Mae")
and the Export-Import Bank, are supported by the full faith and credit of the
U.S. Treasury; others, such as the Federal National Mortgage Association
("Fannie Mae"), are supported by the right of the issuer to borrow from the
Treasury; others are supported by the discretionary authority of the U.S.
government to purchase the agency's obligations; and still others, such as the
Federal Farm Credit Banks and the Federal Home Loan Mortgage Corporation
("Freddie Mac") are supported only by the credit of the instrumentality. No
assurance can be given that the U.S. government would provide financial support
to U.S. government-sponsored agencies or instrumentalities if it is not
obligated to do so by law. A Fund will invest in the obligations of such
agencies or instrumentalities only when Banc One Advisors or the Investment
Sub-Advisor ("Sub-Advisor") believes that the credit risk with respect thereto
is minimal. For information on mortgage-related securities issued by certain
agencies or instrumentalities of the U.S. government, see "Investment Objectives
and Policies--Mortgage-Related Securities" in this Statement of Additional
Information.

LOAN PARTICIPATIONS AND ASSIGNMENTS

         Some of the Funds may invest in fixed and floating rate loans ("Loans")
arranged through private negotiations between an issuer of Sovereign Debt
Obligations and one or more financial institutions ("Lenders"). Investments in
loans are expected in most instances to be in the form of participations in
Loans ("Participations") and assignments of all or a portion of Loans
("Assignments") from third parties. Because loan participants and assignments
may be illiquid, a Fund will invest no more than 15% (10% for the Money Market
Funds) of its net assets in loan participations and other illiquid assets. The
government that is the borrower on the Loan will be considered by the Fund to be
the issuer of a Participations or Assignment for purposes of the fund's
fundamental investment policy that it will not invest 25% or more of its total
assets in securities of issuers conducting their principal business activities
in the same industry (i.e., foreign government). The


                                       4
<PAGE>   250
Funds investment in Participations typically will result in the Fund having a
contractual relationship only with the Lender and not with the borrower.

         When a Fund purchases Assignments from Lenders it will acquire direct
rights against the borrower on the Loan. Because Assignments are arranged
through private negotiations between potential assignees and potential
assignors, however, the rights and obligations acquired by a Fund as the
purchaser of an Assignment may differ from, and be more limited than, those held
by the assigning Lender. The assignability of certain Sovereign Debt Obligations
is restricted by the governing documentation as to the nature of the assignee
such that the only way in which a Fund may acquire an interest in a Loan is
through a Participations and not an Assignment. A Fund may have difficulty
disposing of Assignments and Participations because to do so it will have to
assign such securities to a third party. Because there is no liquid market for
such securities, the Funds anticipate that such securities could be sold only to
a limited number of institutional investors. The lack of a liquid secondary
market may have an adverse impact on the value of such securities and a Fund's
ability to dispose of particular Assignments or Participations when necessary to
meet a Fund's liquidity needs in response to a specific economic event such as a
deterioration in the creditworthiness of the borrower. The lack of a liquid
secondary market for Assignments and Participations also may make it more
difficult for a Fund to assign a value to those securities for purposes of
valuing a Fund's portfolio and calculating its net asset value.

FUTURES AND OPTIONS TRADING

         Some of the Funds may enter into futures contracts, options, options on
futures contracts and stock index futures contracts and options thereon for the
purposes of remaining fully invested, reducing transaction costs, or managing
interest rate risk.

FUTURES CONTRACTS

         Futures contracts provide for the future sale by one party and purchase
by another party of a specified amount of a specific security, class of
securities, or an index at a specified future time and at a specified price. A
stock index futures contract is a bilateral agreement pursuant to which two
parties agree to take or make delivery of an amount of cash equal to a specified
dollar amount times the difference between the stock index value at the close of
trading of the contracts and the price at which the futures contract is
originally struck. Futures contracts which are standardized as to maturity date
and underlying financial instrument are traded on national futures exchanges.
Futures exchanges and trading are regulated under the Commodity Exchange Act by
the Commodity Futures Trading Commission ("CFTC"), a U.S. government agency.

         Although most futures contracts by their terms call for actual delivery
and acceptance of the underlying securities, in most cases the contracts are
closed out before the settlement date without the making or taking of delivery.
Closing out an open futures position is done by taking an opposite position
("buying" a contract which has previously been "sold," or "selling" a contract
previously purchased) in an identical contract to terminate the position. The
acquisition of put and call options on futures contracts will, respectively,
give a Fund the right (but not the obligation), for a specified price, to sell
or to purchase the underlying futures contract, upon exercise of the option, at
any time during the option period. Brokerage commissions are incurred when a
futures contract is bought or sold.

         When making future trades, the Funds are required to make a good faith
margin deposit in cash or government securities with a broker or custodian to
initiate and maintain open positions in futures contracts. A margin deposit is
intended to assure completion of the contract (delivery or acceptance of the
underlying security) if it is not terminated prior to the specified delivery
date. Minimal initial margin requirements are established by the futures
exchange and may be changed. Brokers may establish deposit requirements which
are higher than the exchange minimums. Initial margin deposits on futures
contracts are customarily set at levels much lower than the prices at which the
underlying securities are purchased and sold, typically ranging upward from less
than 5% of the value of the contract being traded.

         After a futures contract position is opened, the value of the contract
is marked to market daily. If the futures contract price changes to the extent
that the margin on deposit does not satisfy margin requirements, payment of
additional "variation" margin will be required. Conversely, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the contract holder. Variation margin payments are made to and
from the futures broker for as long as the contract remains open. The Funds
expect to earn interest income on their margin deposits.

         Traders in futures contracts may be broadly classified as either
"hedgers" or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities otherwise held for investment
purposes or expected to be acquired by them. Speculators are less inclined to
own the securities underlying the futures contracts which they trade, and use
futures contracts with the expectation of realizing profits from fluctuations in
the prices of underlying securities. The Funds intend to enter into futures
contracts, options on futures contracts, index futures and options thereon that
are traded on an exchange regulated by the CFTC if, to the extent that such
futures and options are not for "bona fide hedging purposes" (as defined by the
CFTC), the aggregate initial margin and premiums on such positions (excluding
the amount by which


                                       5
<PAGE>   251
options are in the money) do not exceed 5% of the Fund's total assets at current
value. A Fund, however, may invest more than such amount for bona fide hedging
purposes, and also may invest more than such amount if it obtains authority to
do so from the CFTC without rendering the fund a commodity pool operator or
adversely affecting its status as an investment company for federal securities
laws or income tax purposes.

         A Fund may buy and sell futures contracts and related options to manage
its exposure to changing interest rates and security prices. When interest rates
are expected to rise or market values of portfolio securities are expected to
fall, a Fund can seek through the sale of futures contracts to offset a decline
in the value of its portfolio securities. When interest rates are expected to
fall or market values are expected to rise, a Fund, through the purchase of such
contracts, can attempt to secure better rates or prices for the Fund than might
later be available in the market when it effects anticipated purchases.

         Although techniques other than the sale and purchase of futures
contracts could be used to control the Funds' exposure to market fluctuations,
the use of futures contracts may be a more effective means of managing this
exposure. While the Funds will incur commission expenses in both opening and
closing out futures positions, these costs may be lower than transaction costs
that would be incurred in the purchase and sale of the underlying securities.

         A Fund's ability to effectively utilize futures trading depends on
several factors. First, it is possible that there will not be a perfect price
correlation between the futures contracts and their underlying reference
security or index. Second, it is possible that a lack of liquidity for futures
contracts could exist in the secondary market, resulting in an inability to
close a futures position prior to its maturity date. Third, the purchase of a
futures contract involves the risk that a Fund could lose more than the original
margin deposit required to initiate a futures transaction.

RESTRICTIONS ON THE USE OF FUTURES CONTRACTS

         None of the Funds will enter into futures contract transactions for
purposes other than bona fide hedging purposes to the extent that, immediately
thereafter, the sum of its initial margin deposits and premiums on open
contracts exceeds 5% of the market value of the respective Fund's total assets.
The Funds of Funds will not enter into futures contract transactions, however,
the One Group mutual funds in which they invest may do so as described herein.
In addition, none of the Equity Funds will enter into futures contracts to the
extent that the value of the futures contracts held would exceed 25% of the
respective Fund's total assets. Futures transactions will be limited to the
extent necessary to maintain each Fund's qualification as a regulated investment
company.

         The Funds have undertaken to restrict their futures contract trading as
follows: first, the Funds will not engage in transactions in futures contracts
for speculative purposes; second, the Funds will not market themselves to the
public as commodity pools or otherwise as vehicles for trading in the
commodities futures or commodity options markets; third, the Funds will disclose
to all prospective Shareholders the purpose of and limitations on their
commodity futures trading; fourth, the Funds will submit to the CFTC special
calls for information. Accordingly, registration as a commodities pool operator
with the CFTC is not required.

         In addition to the margin restrictions discussed above, transactions in
futures contracts may involve the segregation of funds pursuant to requirements
imposed by the Securities and Exchange Commission. Under those requirements,
where a Fund has a long position in a futures contract, it may be required to
establish a segregated account (not with a futures commission merchant or
broker) containing cash or certain liquid assets equal to the purchase price of
the contract (less any margin on deposit). For a short position in futures or
forward contracts held by a Fund, those requirements may mandate the
establishment of a segregated account (not with a futures commission merchant or
broker) with cash or certain liquid assets that, when added to the amounts
deposited as margin, equal the market value of the instruments underlying the
futures contracts (but are not less than the price at which the short positions
were established). However, segregation of assets is not required if a Fund
"covers" a long position. For example, instead of segregating assets, a Fund,
when holding a long position in a futures contract, could purchase a put option
on the same futures contract with a strike price as high or higher than the
price of the contract held by the Fund. In addition, where a Fund takes short
positions, or engages in sales of call options, it need not segregate assets if
it "covers" these positions. For example, where a Fund holds a short position in
a futures contract, it may cover by owning the instruments underlying the
contract. The Funds may also cover such a position by holding a call option
permitting it to purchase the same futures contract at a price no higher than
the price at which the short position was established. Where a Fund sells a call
option on a futures contract, it may cover either by entering into a long
position in the same contract at a price no higher than the strike price of the
call option or by owning the instruments underlying the futures contract. A Fund
could also cover this position by holding a separate call option permitting it
to purchase the same futures contract at a price no higher than the strike price
of the call option sold by the Fund.

         The Funds also may engage in straddles and spreads. In a straddle
transaction, the Fund either buys a call and a put or sells a call and a put on
the same security. In a spread, the Fund purchases and sells a call or a put.
The Fund will sell a straddle when Banc One Advisors believes the price of a
security will be stable. The Fund will receive a premium on the sale


                                       6
<PAGE>   252
of the put and the call. A spread permits the Fund to make a hedged investment
that the price of a security will increase or decline.

         In addition, the extent to which a Fund may enter into transactions
involving futures contracts may be limited by the Internal Revenue Code's
requirements for qualification as a registered investment company and the
Trust's intention to qualify as such. In certain circumstances, entry into a
futures contract that substantially eliminates risk of loss and the opportunity
for gain in an "appreciated financial position" will also accelerate gain to the
Funds.

RISK FACTORS IN FUTURES TRANSACTIONS

         Positions in futures contracts may be closed out only on an exchange
which provides a secondary market for such futures. However, there can be no
assurance that a liquid secondary market will exist for any particular futures
contract at any specific time. Thus, it may not be possible to close a futures
position. In the event of adverse price movements, a Fund would continue to be
required to make daily cash payments to maintain the required margin. In such
situations, if a Fund has insufficient cash, it may have to sell portfolio
securities to meet daily margin requirements at a time when it may be
disadvantageous to do so. In addition, a Fund may be required to make delivery
of the instruments underlying futures contracts it holds. The inability to close
options and futures positions also could have an adverse impact on the ability
to effectively hedge such positions. The Funds will minimize the risk that they
will be unable to close out a futures contract by only entering into futures
contracts which are traded on national futures exchanges and for which there
appears to be a liquid secondary market.

         The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing. Because the deposit
requirements in the futures markets are less onerous than margin requirements in
the securities market, there may be increased Participations by speculators in
the futures market which may also cause temporary price distortions. A
relatively small price movement in a futures contract may result in immediate
and substantial loss (as well as gain) to the investor. For example, if at the
time of purchase, 10% of the value of the futures contract is deposited as
margin, a subsequent 10% decrease in the value of the futures contract would
result in a total loss of the margin deposit, before any deduction for the
transaction costs, if the account were then closed out. A 15% decrease would
result in a loss equal to 150% of the original margin deposit if the contract
were closed out. Thus, a purchase or sale of a futures contract may result in
losses in excess of the amount invested in the contract. However, because the
futures strategies engaged in by the Funds are only for risk management
purposes, Banc One Advisors and the Sub-Advisor do not believe that the Funds
are subject to the risks of loss frequently associated with futures
transactions. Each Fund would presumably have sustained comparable losses if,
instead of the futures contract, it had invested in the underlying financial
instrument and sold it after the decline.

         Utilization of futures transactions by a Fund does involve the risk of
imperfect or no correlation where the securities underlying futures contracts
have different maturities than the portfolio securities being hedged. It is also
possible that a Fund could both lose money on futures contracts and also
experience a decline in value of its portfolio securities. There is also the
risk of loss by a Fund of margin deposits in the event of bankruptcy of a broker
with whom the Fund has an open position in a futures contract or related option.

         Most futures exchanges limit the amount of fluctuation permitted in
futures contract prices during a single trading day. The daily limit establishes
the maximum amount that the price of a futures contract may vary either up or
down from the previous day's settlement price at the end of a trading session.
Once the daily limit has been reached in a particular type of contract, no
trades may be made on that day at a price beyond that limit. The daily limit
governs only price movement during a particular trading day and therefore does
not limit potential losses, because the limit may prevent the liquidation of
unfavorable positions. Futures contract prices have occasionally moved to the
daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of future positions and subjecting some
futures traders to substantial losses.

         Some futures strategies, including selling futures, buying puts and
writing covered calls, may reduce the Fund's exposure to price fluctuations.
Other strategies, including buying futures, and buying calls, tend to increase
market exposure. Futures and options may be combined with each other in order to
adjust the risk and return characteristics of the overall portfolio. The Fund
expects to enter into these transactions to manage a return or spread on a
particular investment or portion of its assets, to protect against any increase
in the price of securities the Fund anticipates purchasing at a later date, or
for other risk management strategies.

OPTIONS CONTRACTS

         Some of the Funds may use trading of options on securities or futures
contracts as a hedging device. An option on a futures contract gives the
purchaser of the option the right (but not the obligation) to take a position at
a specified price (the "striking," "strike" or "exercise" price) in the
underlying futures contract or security. A "call" option gives the purchaser the


                                       7
<PAGE>   253
right to take a long (buy) position in the underlying futures contract or
security, and the purchaser of a "put" option acquires the right to take a short
(sell) position in the underlying futures contract or security. The purchase
price of an option is referred to as its "premium." The seller (or "writer") of
an option is obligated to take a futures or securities position at a specified
price if the option is exercised. In the case of a call option, the seller must
stand ready to take a short position (i.e., sell the futures contract or
security) in the underlying futures contract or security at the strike price if
the option is exercised. A seller of a put option, on the other hand, stands
ready to take a long position (i.e., buy the contract or security) in the
underlying futures contract or security at the strike price if the option is
exercised.

         A "naked" option refers to an option written by a party which does not
possess the underlying futures contract or security. A "covered" option refers
to an option written by a party which does possess the underlying position. The
initial purchase (sale) of an option is an "opening transaction." In order to
close out an option position, the Fund may enter into a "closing transaction".
This involves the sale (purchase) of an option contract on the same security
with the same exercise price and expiration date as the option contract
originally opened.

         A call option on a futures contract or security is said to be
"in-the-money" if the strike price is below current market levels. Similarly, a
put option on a futures contract or security is said to be "out-of-the-money" if
the strike price is below current market levels. On the other hand, a put option
is "in-the-money" if the strike price is above current market levels, and
"out-of-the-money" if the strike price is below current market levels.

         Options have limited life spans, usually tied to the delivery or
settlement date of the underlying futures contract or security. Some options,
however, expire significantly in advance of such dates. An option that is
"out-of-the-money" and not offset by the time it expires becomes worthless. On
certain exchanges "in-the-money" options are automatically exercised on their
expiration date, but on others unexercised options simply become worthless after
their expiration date. Options usually trade at a premium (referred to as the
"time value" of the option) above their intrinsic value (the difference between
the market price for the underlying futures contract or equity security and the
strike price). As an option nears its expiration date, the market value and the
intrinsic value move into parity as the time value diminishes.

         Some Funds may enter into over-the-counter option transactions. There
will be an active over-the-counter market for such options which will establish
their pricing and liquidity. Broker/Dealers with whom the Trust will enter into
such option transactions shall have a minimum net worth of $20,000,000. Each
Fund will limit the writing of put and call options to 25% of its net assets.

         Increased market volatility generally increases the value of options by
increasing the probability of favorable market swings, putting outstanding
options "in-the-money." Although purchasing options is a limited risk trading
approach, significant losses can be incurred by doing so.

COVERED CALLS

         Some of the Funds may write (sell) "covered" call options and purchase 
options to close out options previously written by the Fund. The Funds' purpose
in writing covered call options is to generate additional premium income. This
premium income will serve to enhance a Fund's total return and will reduce the
effect of any price decline of the security involved in the option. Although the
International Equity Index Fund has no current intention to write such options,
it reserves the right to do so from time to time when such activity will further
its investment objective. Covered call options will generally be written on
securities which, in the opinion of Banc One Advisors or the Sub-Advisor, are
not expected to make any major price moves in the near future but which, over
the long term, are deemed to be attractive investments for the Fund.

         A call option gives the holder (buyer) the "right to purchase" a
security at a specified price (the exercise price) at any time until a certain
date (the expiration date). So long as the obligation of the writer of a call
option continues, the writer may be assigned an exercise notice by the
broker-dealer through whom such option was sold, requiring the writer to deliver
the underlying security against payment of the exercise price. This obligation
terminates upon the expiration of the call option, or such earlier time at which
the writer effects a closing purchase transaction by repurchasing an option
identical to that previously sold. To secure the writer's obligation to deliver
the underlying security in the case of a call option, subject to the rules of
the Options Clearing Corporation, a writer is required to deposit in escrow the
underlying security or other assets in accordance with such rules. The Funds
will write only covered call options. This means that a Fund will only write a
call option on a security which a Fund already owns.

         Fund securities on which call options may be written will be purchased
solely on the basis of investment considerations consistent with each Fund's
investment objectives. The writing of covered call options is a conservative
investment technique believed to involve relatively little risk (in contrast to
the writing of naked options, which a Fund will not do), but capable of
enhancing the Fund's total return. When writing a covered call option, a Fund,
in return for the premium, gives up the opportunity for profit from a price
increase in the underlying security above the exercise price, but conversely
retains the risk of loss should the price of the security decline. Unlike one
who owns securities not subject to an


                                       8
<PAGE>   254
option, a Fund has no control over when it may be required to sell the
underlying securities, since it may be assigned an exercise notice at any time
prior to the expiration of its obligation as a writer. Thus, the security could
be "called away" at a price substantially below the fair market value of the
security. If a call option which a Fund has written expires, a Fund will realize
a gain in the amount of the premium; however, such gain may be offset by a
decline in the market value of the underlying security during the option period.
If the call option is exercised, a Fund will realize a gain or loss from the
sale of the underlying security. The security covering the call will be
maintained in a segregated account of the Fund's custodian. The Funds do not
consider a security covered by a call to be "pledged" as that term is used in
each Fund's policy which limits the pledging or mortgaging of its assets.

         The premium received is the market value of an option. The premium each
Fund will receive from writing a call option will reflect, among other things,
the current market price of the underlying security, the relationship of the
exercise price to such market price, the historical price volatility of the
underlying security, and the length of the option period. Once the decision to
write a call option has been made, the Fund's Advisor or Sub-Advisor, in
determining whether a particular call option should be written on a particular
security, will consider the reasonableness of the anticipated premium and the
likelihood that a liquid secondary market will exist for those options. The
premium received by a Fund for writing covered call options will be recorded as
a liability in the Trust's statement of assets and liabilities. This liability
will be adjusted daily to the option's current market value, which will be the
latest sale price at the time at which the net asset value per Share of the Fund
is computed (close of the New York Stock Exchange), or, in the absence of such
sale, the latest asked price. The liability will be extinguished upon expiration
of the option, the purchase of an identical option in the closing transaction,
or delivery of the underlying security upon the exercise of the option.

         Generally, a Fund, in order to avoid the exercise of an option sold by
it, will be able to cancel its obligation under the option by entering into a
closing purchase transaction, if available, unless selling (in the case of a
call option) or purchasing (in the case of a put option) the underlying
securities is determined to be in a Fund's best interest. A closing purchase
transaction consists of a Fund purchasing an option having the same terms as the
option sold by a Fund, and has the effect of cancelling a Fund's position as a
seller. The premium which a Fund will pay in executing a closing purchase
transaction may be higher (or lower) than the premium received when the option
was sold, depending in large part upon the relative price of the underlying
security at the time of each transaction. To the extent options sold by a Fund
are exercised and a Fund delivers securities to the holder of a call option, a
Fund's turnover rate will increase, which would cause a Fund to incur additional
brokerage expenses.

         Closing transactions will be effected in order to realize a profit on
an outstanding call option, to prevent an underlying security from being called,
or to permit the sale of the underlying security. Furthermore, effecting a
closing transaction will permit a Fund to write another call option on the
underlying security with either a different exercise price or expiration date or
both. If a Fund desires to sell a particular security from its portfolio on
which it has written a call option it will seek to effect a closing transaction
prior to, or concurrently with, the sale of the security. There is, of course,
no assurance that a Fund will be able to effect such closing transactions at a
favorable price. If a Fund cannot enter into such a transaction, it may be
required to hold a security that it might otherwise have sold, in which case it
would continue to be at market risk on the security. This could result in higher
transaction costs. A Fund will pay transaction costs in connection with the
writing of options to close out previously written options. Such transaction
costs are normally higher than those applicable to purchases and sales of
portfolio securities.

         Call options written by a Fund will normally have expiration dates of
less than nine months from the date written. The exercise price of the options
may be below, equal to, or above the current market values of the underlying
securities at the time the options are written. From time to time, a Fund may
purchase an underlying security for delivery in accordance with an exercise
notice of a call option assigned to it, rather than delivering such security
from its portfolio. In such cases, additional costs will be incurred.

         A Fund will realize a profit or loss from a closing purchase
transaction if the cost of the transaction is less or more than the premium
received from the writing of the option. Because increases in the market price
of a call option will generally reflect increases in the market price of the
underlying security, any loss resulting from the repurchase of a call option is
likely to be offset in whole or in part by appreciation of the underlying
security owned by the Fund.

PURCHASING CALL OPTIONS

         Certain Funds may purchase call options to hedge against an increase in
the price of securities that the Fund wants ultimately to buy. Such hedge
protection is provided during the life of the call option since the Fund, as
holder of the call option, is able to buy the underlying security at the
exercise price regardless of any increase in the underlying security's market
price. In order for a call option to be profitable, the market price of the
underlying security must rise sufficiently above the exercise price to cover the
premium and transaction costs. These costs will reduce any profit the Fund might
have realized had it bought the underlying security at the time it purchased the
call option. In the event that paying premiums for a call


                                       9
<PAGE>   255
option, together with a price movement in the underlying security, is such that
exercise of the option would not be profitable to the Fund, loss of the premium
may be offset by a decrease in the acquisition cost of securities by the Fund.

PURCHASING PUT OPTIONS

         Certain Funds may also purchase put options to protect their portfolio
holdings in an underlying security against a decline in market value. Such hedge
protection is provided during the life of the put option since the Fund, as
holder of the put option, is able to sell the underlying security at the put
exercise price regardless of any decline in the underlying security's market
price. For a put option to be profitable, the market price of the underlying
security must decline sufficiently below the exercise price to cover the premium
and transaction costs. By using put options in this manner, the Fund will reduce
any profit it might otherwise have realized from appreciation of the underlying
security by the premium paid for the put option and by transaction cost.
However, any loss of premium may be offset by an increase in the value of the
Fund's securities.

SECURED PUTS

         Certain Funds may write secured puts. For the secured put writer, 
substantial depreciation in the value of the underlying security would result in
the security being "put to" the writer at the strike price of the option which
may be substantially in excess of the fair market value of the security. If a
secured put option expires unexercised, the writer realizes a gain in the amount
of the premium.

RISK FACTORS IN OPTIONS TRANSACTIONS

         The successful use of the options strategies depends on the ability of
Banc One Advisors or, in the case of the International Equity Index Fund, the
Sub-Advisor, to assess interest rate and market movements correctly and to
accurately calculate the fair price of the option. In addition, there may be
imperfect or no correlation between the changes in market value of the
securities held by the Funds and the prices of the options.

         When it purchases an option, a Fund runs the risk that it will lose its
entire investment in the option in a relatively short period of time, unless the
Fund exercises the option or enters into a closing sale transaction with respect
to the option during the life of the option. If the price of the underlying
security does not rise (in the case of a call) or fall (in the case of a put) to
an extent sufficient to cover the option premium and transaction costs, a Fund
will lose part or all of its investment in the option. This contrasts with an
investment by a Fund in the underlying securities, since the Fund may continue
to hold its investment in those securities notwithstanding the lack of a change
in price of those securities.

         The effective use of options also depends on a Fund's ability to
terminate option positions at times when Banc One Advisors or, in the case of
the International Equity Index Fund, the Sub-Advisor, deems it desirable to do
so. A Fund will take an option position only if Banc One Advisors or, in the
case of the International Equity Index Fund, the Sub-Advisor, believes there is
a liquid secondary market for the option, however, there is no assurance that a
Fund will be able to effect closing transactions at any particular time or at an
acceptable price.

         If a secondary trading market in options were to become unavailable, a
Fund could no longer engage in closing transactions. Lack of investor interest
might adversely affect the liquidity of the market for particular options or
series of options. A marketplace may discontinue trading of a particular option
or options generally. In addition, a market could become temporarily unavailable
if unusual events, such as volume in excess of trading or clearing capability,
were to interrupt normal market operations. A marketplace may at times find it
necessary to impose restrictions on particular types of options transactions,
which may limit a Fund's ability to realize its profits or limit its losses.

         Disruptions in the markets for the securities underlying options
purchased or sold by a Fund could result in losses on the options. If trading is
interrupted in an underlying security, the trading of options on that security
is normally halted as well. As a result, a Fund as purchaser or writer of an
option will be unable to close out its positions until option trading resumes,
and it may be faced with losses if trading in the security reopens at a
substantially different price. In addition, the Options Clearing Corporation
("OCC") or other options markets may impose exercise restrictions. If a
prohibition on exercise is imposed at the time when trading in the option has
also been halted, a Fund as purchaser or writer of an option will be locked into
its position until one of the two restrictions has been lifted. If a prohibition
on exercise remains in effect until an option owned by a Fund has expired, the
Fund could lose the entire value of its option.

         Special risks are presented by internationally-traded options. Because
of time differences between the United States and the various foreign countries,
and because different holidays are observed in different countries, foreign
option markets may be open for trading during hours or on days when U.S. markets
are closed. As a result, option premiums may not reflect the current prices of
the underlying interest in the United States.

MORTGAGE-RELATED SECURITIES

         Certain of the Funds may, consistent with their investment objectives
and policies, invest in mortgage-backed securities issued or guaranteed by the
U.S. government or its agencies or instrumentalities.

         Mortgage-backed securities, for purposes of the Trust's Prospectuses
and this Statement of Additional Information, represent pools of mortgage loans
assembled for sale to investors by various governmental agencies such as the
Government National Mortgage Association ("Ginnie Mae") and government-related
organizations such as the Federal National Mortgage Association ("Fannie Mae")
and the Federal Home Loan Mortgage Corporation ("Freddie Mac"), as well as by
nongovernmental issuers such as commercial banks, savings and loan institutions,
mortgage bankers, and private mortgage insurance companies. Such
non-governmental mortgage securities cannot be treated as U.S. government
securities for purposes of investment policies. The Government Bond Fund, the
Government Money Market Fund and the Treasury & Agency Fund may only invest in
mortgage-backed securities issued or guaranteed by the U.S. government, or its
agencies or instrumentalities. The other Funds listed above also may invest in
mortgage-backed securities issued by non-government entities, which consist of
COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOS") and REAL ESTATE MORTGAGE INVESTMENT
CONDUITS ("REMICS") that are rated in one of the four highest rating categories
by at least one NRSRO at the time of investment or, if unrated, determined by
Banc One Advisors to be of comparable quality. The Funds, including the
Government Bond Fund and Government Money Market Fund, also may invest in
multiple class securities issued by U.S. government agencies and
instrumentalities such as Fannie Mae, Freddie Mac and Ginnie Mae. The Funds,
except the Government Bond Fund, the Government Money Market Fund and the
Treasury & Agency Fund may invest in multiple class securities issued by private
issuers including guaranteed CMOs and REMIC pass-through or Participations
certificates, when consistent with a Fund's investment objective, policies and
limitations. A REMIC is a CMO that qualifies for special tax treatment under the
Code and invests in certain mortgages principally secured by interests in real
property and other permitted investments.

         CMOs and guaranteed REMIC pass-through certificates ("REMIC
Certificates") issued by Fannie Mae, Freddie Mac, Ginnie Mae and private issuers
are types of multiple class pass-through securities. Investors may purchase
beneficial interests in REMICs, which are known as "regular" interests or
"residual" interests. The Funds do not currently intend to purchase residual
interests in REMICs. The REMIC Certificates represent beneficial ownership
interests in a REMIC Trust, generally consisting of mortgage loans or Fannie
Mae, Freddie Mac or Ginnie Mae guaranteed mortgage pass-through certificates
(the "Mortgage Assets"). The obligations of Fannie Mae, Freddie Mac or Ginnie
Mae under their respective guaranty of the REMIC Certificates are obligations
solely of Fannie Mae, Freddie Mac or Ginnie Mae, respectively.

         Fannie Mae REMIC Certificates are issued and guaranteed as to timely
distribution of principal and interest by Fannie Mae. In addition, Fannie Mae
will be obligated to distribute the principal balance of each class of REMIC
Certificates in full, whether or not sufficient funds are otherwise available.

         For Freddie Mac REMIC Certificates, Freddie Mac guarantees the timely
payment of interest, and also guarantees the payment of principal as payments
are required to be made on the underlying mortgage participation certificates
("PCS"). PCS represent undivided interests in specified residential mortgages or
participation therein purchased by Freddie Mac and placed in a PC pool. With
respect to principal payments on PCS, Freddie Mac generally guarantees ultimate
collection of all principal of the related mortgage loans without offset or
deduction. Freddie Mac also guarantees timely payment of principal on certain
PCS referred to as "Gold PCS."

         Ginnie Mae REMIC Certificates guarantee the full and timely payment of
interest and principal on each class of securities (in accordance with the terms
of those classes as specified in the related offering circular supplement). The
Ginnie Mae guarantee is backed by the full faith and credit of the United States
of America.

         REMIC Certificates issued by Fannie Mae, Freddie Mac and Ginnie Mae are
treated as U.S. government securities for purposes of investment policies. CMOs
and REMIC Certificates provide for the redistribution of cash flow to multiple
classes. Each class of CMOs or REMIC Certificates, often referred to as a
"tranche," is issued at a specific adjustable or fixed interest rate and must be
fully retired no later than its final distribution date. This reallocation of
interest and principal results in the redistribution of prepayment risk across
to different classes. This allows for the creation of bonds with more or less
risk than the underlying collateral exhibits. Principal prepayments on the
mortgage loans or the Mortgage Assets underlying the CMOs or REMIC Certificates
may cause some or all of the classes of CMOs or REMIC Certificates to be retired
substantially earlier than their final distribution dates. Generally, interest
is paid or accrues on all classes of CMOs or REMIC Certificates on a monthly
basis.

         The principal of and interest on the Mortgage Assets may be allocated
among the several classes of CMOs or REMIC Certificates in various ways. In
certain structures (known as "sequential pay" CMOs or REMIC Certificates),
payments of principal, including any principal prepayments, on the Mortgage
Assets generally are applied to the classes of CMOs or REMIC Certificates in the
order of their respective final distribution dates. Thus, no payment of
principal will be made on


                                       11
<PAGE>   257
any class of sequential pay CMOs or REMIC Certificates until all other classes
having an earlier final distribution date have been paid in full.

         Additional structures of CMOs and REMIC Certificates include, among
others, "parallel pay" CMOs and REMIC Certificates. Parallel pay CMOs or REMIC
Certificates are those which are structured to apply principal payments and
prepayments of the Mortgage Assets to two or more classes concurrently on a
proportionate or disproportionate basis. These simultaneous payments are taken
into account in calculating the final distribution date of each class.

         A wide variety of REMIC Certificates may be issued in the parallel pay
or sequential pay structures. These securities include accrual certificates
(also know as "Z-Bonds"), which only accrue interest at a specified rate until
all other certificates having an earlier final distribution date have been
retired and are converted thereafter to an interest-paying security, and planned
amortization class ("PAC") certificates, which are parallel pay REMIC
Certificates which generally require that specified amounts of principal be
applied on each payment date to one or more classes of REMIC Certificates (the
"PAC Certificates"), even though all other principal payments and prepayments of
the Mortgage Assets are then required to be applied to one or more other classes
of the certificates. The scheduled principal payments for the PAC Certificates
generally have the highest priority on each payment date after interest due has
been paid to all classes entitled to receive interest currently. Shortfalls, if
any, are added to the amount of principal payable on the next payment date. The
PAC Certificate payment schedule is taken into account in calculating the final
distribution date of each class of PAC. In order to create PAC tranches, one or
more tranches generally must be created that absorb most of the volatility in
the underlying Mortgage Assets. These tranches tend to have market prices and
yields that are much more volatile than the PAC classes.

         The Z-Bonds in which the Funds may invest may bear the same non-credit-
related risks as do other types of Z-Bonds. Z-Bonds in which the Fund may invest
will not include residual interest.

         There can be no assurance that the U.S. government would provide
financial support to Fannie Mae, Freddie Mac or Ginnie Mae if necessary in the
future.

         Although certain mortgage-related securities are guaranteed by a third
party or otherwise similarly secured, the market value of the security, which
may fluctuate, is not so secured. If a Fund of the Trust purchases a
mortgage-related security at a premium, that portion may be lost if there is a
decline in the market value of the security whether resulting from changes in
interest rates or prepayments in the underlying mortgage collateral. As with
other interest-bearing securities, the prices of such securities are inversely
affected by changes in interest rates. However, though the value of a
mortgage-related security may decline when interest rates rise, the converse is
not necessarily true since in periods of declining interest rates the mortgages
underlying the securities are prone to prepayment. For this and other reasons, a
mortgage-related security's stated maturity may be shortened by unscheduled
prepayments on the underlying mortgages and, therefore, it is not possible to
predict accurately the security's return to the Trust's Funds. In addition,
regular payments received in respect of mortgage-related securities include both
interest and principal. No assurance can be given as to the return the Funds of
the Trust will receive when these amounts are reinvested.

         The market value of the Fund's adjustable rate Mortgage-Backed
Securities may be adversely affected if interest rates increase faster than the
rates of interest payable on such securities or by the adjustable rate mortgage
loans underlying such securities. Furthermore, adjustable rate Mortgage-Backed
Securities or the mortgage loans underlying such securities may contain
provisions limiting the amount by which rates may be adjusted upward and
downward and may limit the amount by which monthly payments may be increased or
decreased to accommodate upward and downward adjustments in interest rates.

         Certain adjustable rate mortgage loans may provide for periodic
adjustments of scheduled payments in order to amortize fully the mortgage loan
by its stated maturity. Other adjustable rate mortgage loans may permit their
stated maturity to be extended or shortened in accordance with the portion of
each payment that is applied to interest as affected by the periodic interest
rate adjustments.

         Although having less risk of decline during periods of rising interest
rates, adjustable rate Mortgage-Backed Securities have less potential for
capital appreciation than fixed rate Mortgage-Backed Securities because their
coupon rates will decline in response to market interest rate declines. The
market value of fixed rate Mortgage-Backed Securities may be adversely affected
as a result of increases in interest rates and, because of the risk of
unscheduled principal prepayments, may benefit less than other fixed rate
securities of similar maturity from declining interest rates. Finally, to the
extent Mortgage-Backed Securities are purchased at a premium, mortgage
foreclosures and unscheduled principal prepayments may result in some loss of
the Fund's principal investment to the extent of the premium paid. On the other
hand, if such securities are purchased at a discount, both a scheduled payment
of principal and an unscheduled prepayment of principal will increase current
and total returns and will accelerate the recognition of income.

         The Bond Funds and the Asset Allocation Fund may invest in
mortgage-related securities which are collateralized mortgage obligations
structured on pools of mortgage pass-through certificates or mortgage loans.
Collateralized mortgage


                                       12

obligations will be purchased only if rated in the four highest rating
categories by a nationally recognized rating organization such as Moody's or
S&P.

         There are a number of important differences among the agencies and
instrumentalities of the U.S. government that issue mortgage-related securities
and among the securities that they issue. Mortgage-related securities issued by
Ginnie Mae include Ginnie Mae Mortgage Pass-Through Certificates which are
guaranteed as to the timely payment of principal and interest by Ginnie Mae and
such guarantee is backed by the full faith and credit of the United States.
Ginnie Mae is a wholly-owned U.S. government corporation within the Department
of Housing and Urban Development. Ginnie Mae certificates also are supported by
the authority of Ginnie Mae to borrow funds from the U.S. Treasury to make
payments under its guarantee. Mortgage-related securities issued by Fannie Mae
include Fannie Mae Guaranteed Mortgage Pass-Through Certificates which are
solely the obligations of Fannie Mae and are not backed by or entitled to the
full faith and credit of the United States. Fannie Mae is a government-sponsored
organization owned entirely by private stock-holders. Fannie Mae Certificates
are guaranteed as to timely payment of the principal and interest by Fannie Mae.
Mortgage-related securities issued by Freddie Mac include Freddie Mac Mortgage
Participation Certificates. Freddie Mac is a corporate instrumentality of the
United States, created pursuant to an Act of Congress, which is owned entirely
by Federal Home Loan Banks. Freddie Mac Certificates are not guaranteed by the
United States or by any Federal Home Loan Banks and do not constitute a debt or
obligation of the United States or of any Federal Home Loan Bank. Freddie Mac
Certificates entitle the holder to timely payment of interest, which is
guaranteed by Freddie Mac. Freddie Mac guarantees either ultimate collection or
timely payment of all principal payments on the underlying mortgage loans. When
Freddie Mac does not guarantee timely payment of principal, Freddie Mac may
remit the amount due on account of its guarantee of ultimate payment of
principal at any time after default on an underlying mortgage, but in no event
later than one year after it becomes payable.

         The Funds may enter into MORTGAGE DOLLAR ROLLS in which the Funds sell
securities for delivery in the current month and simultaneously contract with
the same counterparty to repurchase similar (same type, coupon and maturity) but
not identical securities on a specified future date. When a Fund enters into
mortgage dollar rolls, the Fund will hold and maintain a segregated account
until the settlement date, cash or liquid, high grade debt securities in an
amount equal to the forward purchase price. The Funds benefit to the extent of
any difference between the price received for the securities sold and the lower
forward price for the future purchase (often referred to as the "drop") or fee
income plus the interest earned on the cash proceeds of the securities sold
until the settlement date of the forward purchase. Unless such benefits exceed
the income, capital appreciation and gain or loss due to mortgage prepayments
that would have been realized on the securities sold as part of the mortgage
dollar roll, the use of this technique will diminish the investment performance
of the Funds compared with what such performance would have been without the use
of mortgage dollar rolls. The benefits derived from the use of mortgage dollar
rolls may depend upon Banc One Advisors' ability to predict correctly mortgage
prepayments and interest rates. There is no assurance that mortgage dollar rolls
can be successfully employed. The Funds currently intend to enter into mortgage
dollar rolls that are accounted for as a financing transaction. For purposes of
diversification and investment limitations, mortgage dollar rolls are considered
to be mortgage-backed securities.

         The Bond Funds, (other than the Limited Volatility Bond Fund and the
Treasury & Agency Fund), and the Asset Allocation Fund may invest in certain
STRIPPED MORTGAGE-BACKED SECURITIES ("SMBS") that are extremely sensitive to
changes in prepayments and interest rates. Even though such securities have been
guaranteed by an agency or instrumentality of the U.S. government, under certain
interest rate or prepayment rate scenarios, the Funds may fail to fully recover
their investment in such securities. The Funds may invest in SMBS to enhance
revenues or hedge against interest rate risk. SMBS are derivative multi-class
mortgage securities. The Funds may only invest in SMBS issued or guaranteed by
the U.S. government, its agencies or instrumentalities. SMBS are usually
structured with two classes that receive different proportions of the interest
and principal distributions from a pool of mortgage assets. A common type of
SMBS will have one class receiving all of the interest from the mortgage assets
(" IOs"), while the other class will receive all of the principal ("POs").
Mortgage IOs receive monthly interest payments based upon a notional amount that
declines over time as a result of the normal monthly amortization and
unscheduled prepayments of principal on the associated mortgage POs. Changes in
prepayment rates can cause the return on investment in IOs to be highly
volatile, and under extremely high prepayment conditions IOs can incur
significant losses. POs are bought at a discount to the ultimate principal
repayment value. The rate of return on a PO will vary with prepayments, rising
as prepayment increase and falling as prepayments decrease. Although the market
for such securities is increasingly liquid, certain SMBS may not be readily
marketable and will be considered illiquid for purposes of the Funds'
limitations on investments in illiquid securities. The market value of the class
consisting entirely of principal payments generally is unusually volatile in
response to changes in interest rates. The yields on a class of SMBS that
receives all or most of the interest from mortgage assets 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 any
premium paid will not be fully recouped. Banc One Advisors will seek to manage
these risks (and potential benefits) by investing in a variety of such
securities and by using certain analytical and hedging techniques.










         The yield characteristics of Mortgage-Backed Securities differ from
those of traditional fixed income securities. The major differences typically
include more frequent interest and principal payments, usually monthly, and the
possibility that prepayments of principal may be made at any time. Prepayment
rates are influenced by changes in current interest rates and


                                       13
<PAGE>   259
a variety of economic, geographic, social and other factors and cannot be
predicted with certainty. As with fixed rate mortgage loans, adjustable rate
mortgage loans may be subject to a greater prepayment rate in a declining
interest rate environment. The yields to maturity of the Mortgage-Backed
Securities in which the Trust invests will be affected by the actual rate of
payment (including prepayments) of principal of the underlying mortgage loans.
The mortgage loans underlying such securities generally may be prepaid at any
time without penalty. In a fluctuating interest rate environment, a predominant
factor affecting the prepayment rate on a pool of mortgage loans is the
difference between the interest rates on the mortgage loans and prevailing
mortgage loan interest rates (giving consideration to the cost of any
refinancing). In general, if mortgage loan interest rates fall sufficiently
below the interest rates on fixed rate mortgage loans underlying mortgage
pass-through securities, the rate of prepayment would be expected to increase.
Conversely, if mortgage loan interest rates rise above the interest rates on the
fixed rate mortgage loans underlying the mortgage pass-through securities, the
rate of prepayment may be expected to decrease.

         The Bond Funds and the Asset Allocation Fund, may invest in ADJUSTABLE
RATE MORTGAGE LOANS ("ARMS"). The Treasury & Agency Fund will buy only
government ARMs. ARMs eligible for inclusion in a mortgage pool will generally
provide for a fixed initial mortgage interest rate for a specified period of
time. Thereafter, the interest rates (the "Mortgage Interest Rates") may be
subject to periodic adjustment based on changes in the applicable index rate
(the "Index Rate"). The adjusted rate would be equal to the Index Rate plus a
gross margin, which is a fixed percentage spread over the Index Rate established
for each ARM at the time of its origination.

         Adjustable interest rates can cause payment increases that some
borrowers may find difficult to make. However, certain ARMs may provide that the
Mortgage Interest Rate may not be adjusted to a rate above an applicable
lifetime maximum rate or below an applicable lifetime minimum rate for such ARM.
Certain ARMs may also be subject to limitations on the maximum amount by which
the Mortgage Interest Rate may adjust for any single adjustment period (the
"Maximum Adjustment"). Other ARMs ("Negatively Amortizing ARMs") may provide
instead or as well for limitations on changes in the monthly payment on such
ARMs. Limitations on monthly payments can result in monthly payments which are
greater or less than the amount necessary to amortize a Negatively Amortizing
ARM by its maturity at the Mortgage Interest Rate in effect in any particular
month. In the event that a monthly payment is not sufficient to pay the interest
accruing on a Negatively Amortizing ARM, any such excess interest is added to
the principal balance of the loan, causing negative amortization and will be
repaid through future monthly payments. It may take borrowers under Negatively
Amortizing ARMs longer periods of time to achieve equity and may increase the
likelihood of default by such borrowers. In the event that a monthly payment
exceeds the sum of the interest accrued at the applicable Mortgage Interest Rate
and the principal payment which would have been necessary to amortize the
outstanding principal balance over the remaining term of the loan, the excess
(or "accelerated amortization") further reduces the principal balance of the
ARM. Negatively Amortizing ARMs do not provide for the extension of their
original maturity to accommodate changes in their Mortgage Interest Rate. As a
result, unless there is a periodic recalculation of the payment amount (which
there generally is), the final payment may be substantially larger than the
other payments. These limitations on periodic increases in interest rates and on
changes in monthly payment protect borrowers from unlimited interest rate and
payment increases.

         There are two main categories of indices which provide the basis for
rate adjustments on ARMs: those based on U.S. Treasury securities and those
derived from a calculated measure such as a cost of funds index or a moving
average of mortgage rates. Commonly utilized indices include the one-year,
three-year and five-year constant maturity Treasury bill rates, the three-month
Treasury bill rate, the 180-day Treasury bill rate, rates on longer-term
Treasury securities, the 11th District Federal Home Loan Bank Cost of Funds, the
National Median Cost of Funds, the one-month, three-month, six-month or one-year
London Interbank Offered Rate ("LIBOR"), the prime rate of a specific bank, or
commercial paper rates. Some indices, such as the one-year constant maturity
Treasury rate, closely mirror changes in market interest rate levels. Others,
such as the 11th District Federal Home Loan Bank Cost of Funds index, tend to
lag behind changes in market rate levels and tend to be somewhat less volatile.
The degree of volatility in the market value of the Fund's portfolio and
therefore in the net asset value of the Fund's shares will be a function of the
length of the interest rate reset periods and the degree of volatility in the
applicable indices.

         In general, changes in both prepayment rates and interest rates will
change the yield on Mortgage-Backed Securities. The rate of principal
prepayments with respect to ARMs has fluctuated in recent years. As is the case
with fixed mortgage loans, ARMs may be subject to a greater rate of principal
prepayments in a declining interest rate environment. For example, if prevailing
interest rates fall significantly, ARMs could be subject to higher prepayment
rates than if prevailing interest rates remain constant because the availability
of fixed rate mortgage loans at competitive interest rates may encourage
mortgagors to refinance their ARMs to "lock-in" a lower fixed interest rate.
Conversely, if prevailing interest rates rise significantly, ARMs may prepay at
lower rates than if prevailing rates remain at or below those in effect at the
time such ARMs were originated. As with fixed rate mortgages, there can be no
certainty as to the rate of prepayments on the ARMs in either stable or changing
interest rate environments. In addition, there can be no certainty as to whether
increases in the principal balances of the ARMs due to the addition of deferred
interest may result in a default rate higher than that on ARMs that do not
provide for negative amortization. Other factors affecting prepayment of ARMs
include changes in mortgagors' housing needs, job transfers, unemployment,
mortgagors' net equity in the mortgage properties and servicing decisions.

REAL ESTATE INVESTMENT TRUSTS ("REITS")

         Certain of the Funds may invest without limitation in shares of REITs.
REITs are pooled investment vehicles which invest primarily in income producing
real estate or real estate related loans or interest. REITs are generally
classified as equity REITs, mortgage REITs or a combination of equity and
mortgage REITs. Equity REITs invest the majority of their assets directly in
real property and derive income primarily from the collection of rents. Equity
REITs can also realize capital gains by selling property that have appreciated
in value. Mortgage REITs invest the majority of their assets in real estate
mortgages and derive income from the collection of interest payments. Similar to
investment companies, REITs are not taxed on income distributed to shareholders
provided they comply with several requirements of the Internal Revenue Code of
1986, as amended (the "Code"). A Fund will indirectly bear its proportionate
share of expenses incurred by REITs in which a Fund invests in addition to the
expenses incurred directly by a Fund.

         Investing in REITS involves certain unique risks in addition to those
risks associated with investing in the real estate industry in general. Equity
REITs may be affected by changes in the value of the underlying property owned
by the REITs, while mortgage REITS may be affected by the quality of any credit
extended. REITs are dependent upon management skills, are not diversified, are
subject to heavy cash flow dependency, default by borrowers and
self-liquidation. REITs are also subject to the possibilities of failing to
qualify for tax free pass-through of income under the Code and failing to
maintain their exemption from registration under the Act.

         REITs (especially mortgage REITs) are also subject to interest rate
risks. When interest rates decline, the value of a REIT's investment in fixed
rate obligations can be expected to rise. Conversely, when interest rates rise,
the value of a REIT's investment in fixed rate obligations can be expected to
decline. In contrast, as interest rates on adjustable rate mortgage loans are
reset periodically, yields on a REIT's investments in such loans will gradually
align themselves to fluctuate less dramatically in response to interest rate
fluctuations than would investments in fixed rate obligations.

         Investment in REITs involves risks similar to those associated with
investing in small capitalization companies. REITs may have limited financial
resources, may trade less frequently and in a limited volume and may be subject
to more abrupt or erratic price movements than larger company securities.
Historically, small capitalization stocks, such as REITs, have been more
volatile in price than the larger capitalization stocks included in the S&P
Index of 500 Common Stocks.

FOREIGN INVESTMENTS

         Some of the Funds may invest in certain obligations or securities of
foreign issuers. Possible investments include equity securities of foreign
entities, obligations of foreign branches of U.S. banks and of foreign banks,
including, without limitation, European Certificates of Deposit, European Time
Deposits, European Banker's Acceptances, Canadian Time Deposits and Yankee
Certificates of Deposits, and investments in Canadian Commercial Paper, foreign
securities and Europaper (as those terms are defined in the relevant
Prospectuses of the Trust). Securities of foreign issuers may include sponsored
and unsponsored American Depository Receipts ("ADRs"). Sponsored ADRs are listed
on the New York Stock Exchange; unsponsored ADRs are not. Therefore, there may
be less information available about the issuers of unsponsored ADRs than the
issuers of sponsored ADRs. Unsponsored ADRs are restricted securities. These
instruments may subject a Fund to investment risks that differ in some respects
from those related to investments in obligations of U.S. domestic issuers. Such
risks include future adverse political and economic developments, the possible
imposition of withholding taxes on interest or other income, possible seizure,
nationalization or expropriation of foreign deposits, the possible establishment
of exchange controls or taxation at the source, greater fluctuations in value
due to changes in exchange rates, or the adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on such obligations. Such investments may also entail higher custodial fees and
sales commissions than domestic investments. Foreign issuers of securities or
obligations are often subject to accounting treatment and engage in business
practices different from those respecting domestic issuers of similar securities
or obligations. Foreign branches of U.S. banks and foreign banks are not
regulated by U.S. banking authorities and may be subject to less stringent
reserve requirements than those applicable to domestic branches of U.S. banks.
In addition, foreign banks generally are not bound by the accounting, auditing,
and financial reporting standards comparable to those applicable to U.S. banks.
Investments in all types of foreign obligations or securities will not exceed
25% of the net assets of the Asset Allocation Fund, the Equity Funds (with the
exception of the International Equity Index Fund) and the Income Bond and
Limited Volatility Bond Funds.

         By investing in foreign securities, the International Equity Index Fund
attempts to take advantage of differences between both economic trends and the
performance of securities markets in the various countries, regions and
geographic areas as prescribed by the Fund's investment objective and policies.
During certain periods the investment return on securities in some or all
countries may exceed the return on similar investments in the United States,
while at other times the investment return may be less than that on similar U.S.
securities. Shares of the International Equity Index Fund, when included in
appropriate amounts in a portfolio otherwise consisting of domestic securities,
will provide a source of increased diversification. The International Equity
Index Fund itself seeks increased diversification by combining securities from
various countries and geographic areas that offer different investment
opportunities and are affected by different economic


                                       15
<PAGE>   261
trends. The international investments of the International Equity Index Fund may
reduce the effect that events in any one country or geographic area will have on
its investment holdings. Of course, negative movement by one of a Fund's
investments in one foreign market represented in its portfolio may offset
potential gains from the Fund's investments in another country's markets.

PERCS*

         The Equity Funds may invest in Preferred Equity Redemption Cumulative
Stock ("PERCS") which is a form of convertible preferred stock that actually has
more of an equity component than it does fixed income characteristics. These
instruments permit companies to raise capital via a surrogate for common equity.
PERCS are preferred stock which convert to common stock after a specified period
of time, usually three years, and are considered the equivalent of equity by the
ratings agencies. Issuers pay holders a substantially higher dividend yield than
that on the underlying common, and in exchange, the holder's appreciation is
capped, usually at about 30 percent. PERCS are callable at any time. The PERC is
mandatorily convertible into common stock, but is callable at any time at an
initial call price that reflects a substantial premium to the stock's issue
price. PERCS offer a higher dividend than that available on the common stock,
but in exchange the investors agree to the company placing a cap on the
potential price appreciation. The call price declines daily in an amount that
reflects the incremental dividend that holders enjoy. PERCS are listed on an
exchange where the common stock is listed.

         *PERCS is a registered trademark of Morgan Stanley, which does not
sponsor and is in no way affiliated with The One Group.

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS

         Some funds may purchase securities on a "when-issued" and forward
commitment basis. When a Fund agrees to purchase securities, the Fund's
custodian will set aside cash or liquid portfolio securities equal to the amount
of the commitment in a separate account. The Funds may purchase securities on a
when-issued basis when deemed by Banc One Advisors to present attractive
investment opportunities. When-issued securities are purchased for delivery
beyond the normal settlement date at a stated price and yield, thereby involving
the risk that the yield obtained will be less than that available in the market
at delivery. The Funds generally will not pay for such securities or earn
interest on them until received. Although the purchase of securities on a
when-issued basis is not considered to be leveraging, it has the effect of
leveraging. When Banc One Advisors purchases a when-issued security, the
Custodian will set aside cash or liquid securities to satisfy the purchase
commitment. In such a case, a Fund may be required subsequently to place
additional assets in the separate account in order to assure that the value of
the account remains equal to the amount of the Fund's commitment. It may be
expected that a Fund's net assets will fluctuate to a greater degree when it
sets aside portfolio securities to cover such purchase commitments than when it
sets aside cash. No Fund intends to purchase "when-issued" securities for
speculative purposes but only for the purpose of acquiring portfolio securities.
Because a Fund will set aside cash or liquid portfolio securities to satisfy its
purchase commitments in the manner described, the Fund's liquidity and the
ability of Banc One Advisors and the Sub-Advisor to manage the Fund might, as
described in the Prospectuses, be affected in the event its commitments to
purchase when-issued securities ever exceeded 40% of the value of its assets.
Commitments to purchase when-issued securities will not, under normal market
conditions, exceed 25% of a Fund's total assets, and a commitment will not
exceed 90 days. A Fund may dispose of a when-issued security or forward
commitment prior to settlement if Banc One Advisors deems it appropriate to do
so. When a Fund engages in "when-issued" transactions, it relies on the seller
to consummate the trade. Failure of the seller to do so may result in the Fund's
incurring a loss or missing the opportunity to obtain a price considered to be
advantageous.

         In a forward commitment transaction, the Funds contract to purchase
securities for a fixed price at a future date beyond customary settlement time.
The Funds are required to hold and maintain in a segregated account until the
settlement date, cash, U.S. government securities or liquid high-grade debt
obligations in an amount sufficient to meet the purchase price. Alternatively,
the Funds may enter into offsetting contracts for the forward sale of other
securities that they own. The purchase of securities on a when-issued or forward
commitment basis involves a risk of loss if the value of the security to be
purchased declines prior to the settlement date.

SECURITIES LENDING

         In order to generate additional income, each of the Funds, except the
Funds of Funds, may lend up to 33% of the securities in which they are invested
pursuant to agreements requiring that the loan be continuously secured by cash,
securities of the U.S. government or its agencies, shares of an investment trust
or mutual fund or any combination of cash and such securities as collateral
equal at all times to at least 100% of the market value plus accrued interest on
the securities lent. The Funds will continue to receive interest on the
securities lent while simultaneously seeking to earn interest on the investment
of cash collateral in U.S. government securities, shares of an investment trust
or mutual fund, or other short-term, highly liquid investments. Collateral is
marked to market daily to provide a level of collateral at least equal to the
market value of the securities lent. There may be risks of delay in recovery of
the securities or even loss of rights in the collateral


                                       16
<PAGE>   262
should the borrower of the securities fail financially. However, loans will only
be made to borrowers deemed by Banc One Advisors to be of good standing under
guidelines established by the Trust's Board of Trustees and when, in the
judgment of Banc One Advisors, the consideration which can be earned currently
from such securities loans justifies the attendant risk. Loans are subject to
termination by the Funds or the borrower at any time, and are therefore, not
considered to be illiquid investments.

INDEX INVESTING BY THE EQUITY INDEX AND INTERNATIONAL EQUITY INDEX FUNDS

         It is anticipated that the indexing approach that will be employed by
the Equity Index Fund will be an effective method of substantially tracking
percentage changes in the S&P 500 Index (the "Index"). It is a reasonable
expectation that there will be a close correlation between the Fund's
performance and that of the Index in both rising and falling markets. The Fund
will attempt to achieve a correlation between the performance of its portfolio
and that of the Index of at least 0.95, without taking into account expenses. A
correlation of 1.00 would indicate perfect correlation, which would be achieved
when the Fund's net asset value, including the value of its dividend and capital
gains distributions, increases or decreases in exact proportion to changes in
the Index. The Fund's ability to correlate its performance with the Index,
however, may be affected by, among other things, changes in securities markets,
the manner in which the Index is calculated by Standard & Poor's Corporation
("S&P") and the timing of purchases and redemptions. In the future, the Trustees
of the Trust, subject to the approval of Shareholders, may select another index
if such a standard of comparison is deemed to be more representative of the
performance of common stocks.

         S&P chooses the stocks to be included in the Index largely on a
statistical basis. Inclusion of a stock in the Index in no way implies an
opinion by S&P as to its attractiveness as an investment. The Index is
determined, composed and calculated by S&P without regard to the Equity Index
Fund. S&P is neither a sponsor of, nor in any way affiliated with the Equity
Index Fund, and S&P makes no representation or warranty, expressed or implied on
the advisability of investing in the Equity Index Fund or as to the ability of
the Index to track general stock market performance, and S&P disclaims all
warranties of merchantability or fitness for a particular purpose or use with
respect to the Index or any data included therein. "Standard and Poor's 500" is
a service mark of S&P.

         The weightings of stocks in the Index are based on each stock's
relative total market value, i.e., market price per share times the number of
Shares outstanding. Because of this weighting, approximately 50% of the Index is
currently composed of the 50 largest companies in the Index, and the Index
currently represents over 65% of the market value of all U.S. common stocks
listed on the New York Stock Exchange. Typically, companies included in the
Index are the largest and most dominant firms in their respective industries.

         Banc One Advisors generally selects stocks for the Equity Index Fund in
the order of their weightings in the Index beginning with the heaviest weighted
stocks. The percentage of the Equity Index Fund's assets to be invested in each
stock is approximately the same as the percentage it represents in the Index. No
attempt is made to manage the Equity Index Fund in the traditional sense using
economic, financial and market analysis. The Equity Index Fund is managed using
a computer program to determine which stocks are to be purchased and sold to
replicate the Index to the extent feasible. From time to time, administrative
adjustments may be made in the Fund because of changes in the composition of the
Index, but such changes should be infrequent.

         It is anticipated that the indexing approach that will be employed by
the International Equity Index Fund will be an effective method of substantially
tracking percentage changes in the GDP weighted MSCI EAFE Index (the
"International Index"). The Fund will attempt to achieve a correlation between
the performance of its portfolio and that of the International Index of at least
0.95, without taking into account expenses. It is a reasonable expectation that
there will be a close correlation between the Fund's performance and that of the
International Index in both rising and falling markets. A correlation of 1.00
would indicate perfect correlation, which would be achieved when the Fund's net
asset value, including the value of its dividend and capital gains
distributions, increases or decreases in exact proportion to changes in the
International Index. The Fund's ability to correlate its performance with the
International Index, however, may be affected by, among other things, changes in
securities markets, the manner in which the International Index is calculated by
Morgan Stanley International ("MSCI") and the timing of purchases and
redemptions. In the future, the Trustees of the Trust, subject to the approval
of Shareholders, may select another index if such a standard of comparison is
deemed to be more representative of the performance of common stocks.

         MSCI computes and publishes the International Index. MSCI also computes
the country weights which are established based on annual GDP data. Gross
Domestic Product is defined as a country's Gross National Product, or total
output of goods and services, adjusted by the following two factors: net labor
income (labor income of domestic residents working abroad less labor income of
foreigners working domestically) plus net interest income (interest income
earned from foreign investments less interest income earned from domestic
investments by foreigners). Country weights are thus established in proportion
to the size of their economies as measured by Gross Domestic Product, which
results in a more


                                       17
<PAGE>   263
uniform distribution of capital across the EAFE markets than if capitalization
weights were used as the basis. The country weights within the International
Index are systematically rebalanced annually to the most recent GDP weights.

         MSCI chooses the stocks to be included in the International Index
largely on a statistical basis. Inclusion of a stock in the International Index
in no way implies an opinion by MSCI as to its attractiveness as an investment.
The International Index is determined, composed and calculated by MSCI without
regard to the International Equity Index Fund. MSCI is neither a sponsor of, nor
in any way affiliated with the International Equity Index Fund, and MSCI makes
no representation or warranty, expressed or implied on the advisability of
investing in the International Equity Index Fund or as to the ability of the
International Index to track general stock market performance, and MSCI
disclaims all warranties of merchantability or fitness for a particular purpose
or use with respect to the International Index or any data included therein.

FOREIGN CURRENCY TRANSACTIONS OF THE INTERNATIONAL EQUITY INDEX FUND

         Banc One Advisors or the Sub-Advisor of the International Equity Index
Fund may, if it so chooses, engage in various strategies to hedge against
interest rate and currency risks. These strategies may consist of use of any of
the following, some of which also have been described above: options on Fund
positions or currencies, financial and currency futures, options on such
futures, forward foreign currency transactions, forward rate agreements and
interest rate and currency swaps, caps and floors. The Fund may engage in such
transactions in both U.S. and non-U.S. markets. To the extent the Fund enters
into such transactions in markets other than in the United States, the Fund may
be subject to certain currency, settlement, liquidity, trading and other risks
similar to those described above with respect to the Fund's investments in
foreign securities. The Fund may enter into such transactions only in connection
with hedging strategies. While the Fund's use of hedging strategies is intended
to reduce the volatility of the net asset value of Fund shares, the net asset
value of the Fund will fluctuate. There can be no assurance that the Fund's
hedging transactions will be effective. Furthermore, the Fund may only engage in
hedging activities from time to time and may not necessarily be engaging in
hedging activities when movements in interest rates or currency exchange rates
occur. Tax requirements may limit the Fund's ability to engage in the hedging
transactions and strategies described below.

         A substantial portion of the securities of the Fund will be denominated
in foreign currencies, and the Fund may hold funds in foreign currencies. Thus,
the value of the Fund's shares will be affected by changes in currency exchange
rates. The value of the Fund's investments denominated in foreign currencies and
any funds held in foreign currencies will depend on the relative strength of
those currencies and the U.S. Dollar, and the funds may be affected favorably or
unfavorably by exchange control regulations or changes in exchange rates between
foreign currencies and the U.S. Dollar. Changes in the foreign currency exchange
rates also may affect the value of dividends and interest earned, gains and
losses realized on the sale of securities and net investment income and gains,
if any, to be distributed to Shareholders by the Fund. The exchange rates
between the U.S. Dollar and other currencies are determined by the forces of
supply and demand in foreign exchange markets. Accordingly, the ability of the
Fund to achieve its investment objective may depend, to a certain extent, on
exchange rate movements.

         The Fund is authorized to deal in forward foreign exchange between
currencies of the different countries in which the Fund will invest and
multi-national currency units as a hedge against possible variations in the
foreign exchange rate between these currencies. This is accomplished through
contractual agreements entered into in the interbank market to purchase or sell
one specified currency for another currency at a specified future date (up to
one year) and price at the time of the contract. The Fund's dealings in forward
foreign exchange will be limited to hedging involving either specific
transactions or portfolio positions.

        Transaction Hedging. When the Fund engages in transaction hedging, it
enters into foreign currency transactions with respect to specific receivables
or payables of the Fund generally arising in connection with the purchase or
sale of its portfolio securities. The International Equity Index Fund will
engage in transaction hedging when it desires to "lock in" the U.S. dollar price
of a security it has agreed to purchase or sell, or the U.S. dollar equivalent
of a dividend or interest payment in a foreign currency. By transaction hedging,
the International Equity Index Fund will attempt to protect itself against a
possible loss resulting from an adverse change in the relationship between the
U.S. dollar and the applicable foreign currency during the period between the
date on which the security is purchased or sold, or on which the dividend or
interest payment is declared, and the date on which such payments are made or
received.

         The International Equity Index Fund may purchase or sell a foreign
currency on a spot (or cash) basis at the prevailing spot rate in connection
with the settlement of transactions in portfolio securities denominated in that
foreign currency. The Fund may also enter into contracts to purchase or sell
foreign currencies at a future date ("forward contracts"). Although there is no
current intention to do so, the International Equity Index Fund reserves the
right to purchase and sell foreign currency futures contracts traded in the
United States and subject to regulation by the CFTC.


                                       18
<PAGE>   264
         For transaction hedging purposes the International Equity Index Fund
may also purchase U.S. exchange-listed call and put options on foreign currency
futures contracts and on foreign currencies. A put option on a futures contract
gives the Fund the right to assume a short position in the futures contract
until expiration of the option. A put option on currency gives the Fund the
right to sell a currency at an exercise price until the expiration of the
option. A call option on a futures contract gives the Fund the right to assume a
long position in the futures contract until the expiration of the option. A call
option on currency gives the Fund the right to purchase a currency at the
exercise price until the expiration of the option.

         Position Hedging. When it engages in position hedging, the
International Equity Index Fund enters into foreign currency exchange
transactions to protect against a decline in the values of the foreign
currencies in which its portfolio securities are denominated (or an increase in
the value of currency for securities which Banc One Advisors or the Sub-Advisor
expects to purchase, when the Fund holds cash or short-term investments). In
connection with the position hedging, the Fund may purchase or sell foreign
currency forward contracts or foreign currency on a spot basis. The
International Equity Index Fund may purchase U.S. exchange-listed put or call
options on foreign currency and foreign currency futures contracts and buy or
sell foreign currency futures contracts traded in the United States and subject
to regulation by the CFTC, although the International Equity Index Fund has no
current intention to do so.

         The precise matching of the amounts of foreign currency exchange
transactions and the value of the portfolio securities involved will not
generally be possible since the future value of such securities in foreign
currencies will change as a consequence of market movements in the value of
those securities between the dates the currency exchange transactions are
entered into and the dates they mature.

         It is impossible to forecast with precision the market value of
portfolio securities at the expiration or maturity of a forward contract or
futures contract. Accordingly, it may be necessary for the Fund to purchase
additional foreign currency on the spot market (and bear the expense of such
purchase) if the market value of the security or securities being hedged is less
than the amount of foreign currency the Fund is obligated to deliver and if a
decision is made to sell the security or securities and make delivery of the
foreign currency. Conversely, it may be necessary to sell on the spot market
some of the foreign currency received upon the sale of the portfolio security or
securities if the market value of such security or securities exceeds the amount
of foreign currency the Fund is obligated to deliver.

         Although the Fund has no current intention to do so, the International
Equity Index Fund may write covered call options on up to 100% of the currencies
in its portfolio to offset some of the costs of hedging against fluctuations in
currency exchange rates.

         Transaction and position hedging do not eliminate fluctuations in the
underlying prices of the securities which the International Equity Index Fund
owns or expects to purchase or sell. They simply seek to maintain an investment
portfolio that is relatively neutral to fluctuations in the value of the U.S.
Dollar relative to major foreign currencies and establish a rate of exchange
which one can achieve at some future point in time. Additionally, although these
techniques tend to minimize the risk of loss due to a decline in the value of
the hedged currency, they tend to limit any potential gain which might result
from the increase in the value of such currency. Moreover, it may not be
possible for the Fund to hedge against a devaluation that is so generally
anticipated that the Fund is not able to contract to sell the currency at a
price above the anticipated devaluation level. The Fund will not speculate in
forward foreign exchange.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS

         The International Equity Index Fund may purchase forward foreign
currency exchange contracts, which involve an obligation to purchase or sell a
specific currency at a future date, which may be any fixed number of days from
the date of the contract as agreed by the parties, at a price set at the time of
the contract. In the case of a cancellable forward contract, the holder has the
unilateral right to cancel the contract at maturity by paying a specified fee.
The contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. A forward
contract generally has no deposit requirement, and no commissions are charged at
any stage for trades.

         The maturity date of a forward contract may be any fixed number of days
from the date of the contract agreed upon by the parties, rather than a
predetermined date in a given month. Forward contracts may be in any amounts
agreed upon by the parties rather than predetermined amounts. Also, forward
foreign exchange contracts are entered into directly between currency traders so
that no intermediary is required. A forward contract generally requires no
margin or other deposit.

         At the maturity of a forward contract, the Fund may either accept or
make delivery of the currency specified in the contract, or at or prior to
maturity enter into a closing transaction involving the purchase or sale of an
offsetting contract. Closing transactions with respect to forward contracts are
usually effected with the currency trader who is a party to the original forward
contract. Closing transactions with respect to futures contracts are effected on
a commodities exchange; a clearing corporation associated with the exchange
assumes responsibility for closing out such contracts.


                                       19
<PAGE>   265
FOREIGN CURRENCY FUTURES CONTRACTS

         The International Equity Index Fund may purchase forward foreign
currency exchange contracts, foreign currency futures contracts traded in the
United States are designed by and traded on exchanges regulated by the CFTC,
such as the New York Mercantile Exchange. The International Equity Index Fund
would enter into foreign currency futures contracts solely for bona fide hedging
or other appropriate risk management purposes as defined in CFTC regulations.

         When a Fund purchases or sells a futures contract, it is required to
deposit with its custodian an amount of cash or U.S. Treasury bills known as
"initial margin." The nature of initial margin is different from that of margin
in security transactions in that it does not involve borrowing money to finance
transactions. Rather, initial margin is similar to a performance bond or good
faith deposit that is returned to the Fund upon termination of the contract,
assuming the Fund satisfies its contractual obligation.

         Subsequent payments to and from the broker occur on a daily basis in a
process known as "marking to market." These payments are called "variation
margin" and are made as the value of the underlying futures contract fluctuates.
For example, when a Fund sells a futures contract and the price of the
underlying currency rises above the delivery price, the Fund's position declines
in value. The Fund then pays a broker a variation margin payment equal to the
difference between the delivery price of the futures contract and the market
price of the currency underlying the futures contract. Conversely, if the price
of the underlying currency falls below the delivery price of the contract, the
Fund's futures position increases in value. The broker then must make a
variation margin payment equal to the difference between the delivery price of
the futures contract and the market price of the currency underlying the futures
contract.

         When a Fund terminates a position in a futures contract, a final
determination of variation margin is made, additional cash is paid by or to the
Fund, and the Fund realizes a loss or gain. Such closing transactions involve
additional commission costs.

         In addition to the margin requirements discussed above, transactions in
currency futures contracts may involve the segregation of funds pursuant to
requirements imposed by the Securities and Exchange Commission. Under those
requirements, where a Fund has a long position in a futures or forward contract,
it may be required to establish a segregated account (not with a futures
commission merchant or broker) containing cash or certain liquid assets equal to
the purchase price of the contract (less any margin on deposit). For a short
position in futures or forward contracts held by a Fund, those requirements may
mandate the establishment of a segregated account (not with a futures commission
merchant or broker) with cash or certain liquid assets that, when added to the
amounts deposited as margin, equal the market value of the instruments or
currency underlying the futures or forward contracts (but are not less than the
price at which the short positions were established). However, segregation of
assets is not required if the Fund "covers" a long position. For example,
instead of segregating assets, a Fund, when holding a long position in a futures
or forward contract, could purchase a put option on the same futures or forward
contract with a strike price as high or higher than the price of the contract
held by the Fund. In addition, where a Fund takes short positions, or engages in
sales of call options, it need not segregate assets if it "covers" these
positions. For example, where a Fund holds a short position in a futures or
forward contract, it may cover by owning the instruments or currency underlying
the contract. A Fund may also cover such a position by holding a call option
permitting it to purchase the same futures or forward contract at a price no
higher than the price at which the short position was established. Where a Fund
sells a call option on a futures or forward contract, it may cover either by
entering into a long position in the same contract at a price no higher than the
strike price of the call option or by owning the instruments or currency
underlying the futures or forward contract. The Fund could also cover this
position by holding a separate call option permitting it to purchase the same
futures or forward contract at a price no higher than the strike price of the
call option sold by the Fund.

         At the maturity of a futures contract, the Fund may either accept or
make delivery of the currency specified in the contract, or at or prior to
maturity enter into a closing transaction involving the purchase or sale of an
offsetting contract. Closing transactions with respect to forward contracts are
usually effected with the currency trader who is a party to the original forward
contract. Closing transactions with respect to futures contracts are effected on
a commodities exchange; a clearing corporation associated with the exchange
assumes responsibility for closing out such contracts.

         Positions in the foreign currency futures contracts may be closed out
only on an exchange or board of trade which provides a secondary market in such
contracts. Although the International Equity Index Fund intends to purchase or
sell foreign currency futures contracts only on exchanges or boards of trade
where there appears to be an active secondary market, there is no assurance that
a secondary market on an exchange or board of trade will exist for any
particular contract or at any particular time. In such event, it may not be
possible to close a futures position and, in the event of adverse price
movements, the Fund would continue to be required to make daily cash payments of
variation margin.


                                       20
<PAGE>   266
FOREIGN CURRENCY OPTIONS

         The International Equity Index Fund may purchase U.S. exchange-listed
call and put options on foreign currencies. Such options on foreign currencies
operate similarly to options on securities. Options on foreign currencies are
affected by all of those factors which influence foreign exchange rates and
investments generally.

         The Fund is authorized to purchase or sell listed foreign currency
options, and currency swap contracts as a short or long hedge against possible
variations in foreign exchange rates. Such transactions may be effected with
respect to hedges on non-U.S. Dollar denominated securities (including
securities denominated in the ECU) owned by the Fund, sold by the Fund but not
yet delivered, committed or anticipated to be purchased by the Fund, or in
transaction or cross-hedging strategies. As an illustration, the Fund may use
such techniques to hedge the stated value in United States dollars of an
investment in a Japanese yen-dominated security. In such circumstances, for
example, the Fund may purchase a foreign currency put option enabling it to sell
a specified amount of yen for dollars at a specified price by a future date. To
the extent the hedge is successful, a loss in the value of the dollar relative
to the yen will tend to be offset by an increase in the value of the put option.
To offset, in whole or in part, the cost of acquiring such a put option, the
Fund also may sell a call option which, if exercised, requires it to sell a
specified amount of yen for dollars at a specified price by a future date (a
technique called a "straddle"). By selling such call option in this
illustration, the Fund gives up on the opportunity to profit without limit from
increases in the relative value of the yen to the dollar.

         Certain differences exist between these foreign currency hedging
instruments. Foreign currency options provide the holder thereof the right to
buy or to sell a currency at a fixed price on a future date. Listed options are
third-party contracts (i.e., performance of the parties' obligations is
guaranteed by an exchange or clearing corporation) which are issued by a
clearing corporation, traded on an exchange and have standardized strike prices
and expiration dates. OTC options are two-party contracts and have negotiated
strike prices and expiration dates. Options on futures contracts are traded on
boards of trade or futures exchanges. Currency swap contacts are negotiated two
party agreements entered into in the interbank market whereby the parties
exchange two foreign currencies at the inception of the contract and agree to
reverse the exchange at a specified future time and at a specified exchange
rate. The Fund will not speculate in foreign currency options, futures or
related options or currency swap contracts. Accordingly, the Fund will not hedge
a currency substantially in excess (as determined by Banc One Advisors or the
Sub-Adviser) of the market value of the securities denominated in such currency
which it owns, the expected acquisition price of securities which it has
committed or anticipates to purchase which are denominated in such currency,
and, in the cases of securities which have been sold by the Fund but not yet
delivered, the proceeds thereof in its denominated currency. Further the Fund
will segregate, at its Custodian, U.S. government or other high quality
securities having a market value representing any subsequent net decrease in the
market value of such hedged positions including net positions with respect to
cross-currency hedges. The Fund may not incur potential net liabilities with
respect to currency and securities positions, including net liabilities with
respect to cross-currency hedges, of more than 33 1/3% of its total assets from
foreign currency options, futures, related options and forward currency
transactions.

         The value of a foreign currency option is dependent upon the value of
the foreign currency and the U.S. dollar, and may have no relationship to the
investment merits of a foreign security. Because foreign currency transactions
occurring in the interbank market involve substantially larger amounts than
those that may be involved in the use of foreign currency options, investors may
be disadvantaged by having to deal in an odd lot market (generally consisting of
transactions of less than $1 million) for the underlying foreign currencies at
prices that are less favorable than for round lots.

         There is no systematic reporting of last sale information for foreign
currencies and there is no regulatory requirement that quotations available
through dealer or other market sources be firm or revised on a timely basis.
Available quotation information is generally representative of very large
transactions in the interbank market and thus may not reflect relatively smaller
transactions (less than $1 million) where rates may be less favorable. The
interbank market in foreign currencies is a global, around-the-clock market. To
the extent that the U.S. options markets are closed while the markets for the
underlying currencies remain open, significant price and rate movements may take
place in the underlying markets that cannot be reflected in the options market.

FOREIGN CURRENCY CONVERSION

         Although foreign exchange dealers do not charge a fee for currency
conversion, they do realize a profit based on the difference (the "spread")
between prices at which they are buying and selling various currencies. Thus, a
dealer may offer to sell a foreign currency to a Fund at one rate, while
offering a lesser rate of exchange should the Fund desire to resell that
currency to the dealer.

RISK FACTORS IN HEDGING TRANSACTIONS

         All of the foregoing hedging transactions present certain risks. In
particular, the variable degree of correlation between price movements of the
instruments used in hedging strategies and price movements in the security being
hedged


                                       21
<PAGE>   267
creates the possibility that losses on the hedge may be greater than gains in
the value of the Fund's securities. In addition, these instruments may not be
liquid in all circumstances. As a result, in volatile markets, the Fund may not
be able to dispose of or offset a transaction without incurring losses. Although
the contemplated use of hedging instruments should tend to reduce the risk of
loss due to a decline in the value of the hedged security, at the same time the
use of these instruments could tend to limit any potential gain which might
result from an increase in the value of such security.

         Successful use of hedging instruments by the Fund is subject to the
ability of the Banc One Advisors and/or the Sub-Adviser to predict correctly
movements in the direction of interest and currency rates and other factors
affecting markets for securities. If the expectations of the Banc One Advisors
or the Sub-Adviser are not met, the Fund would be in a worse position than if a
hedging strategy had not been pursued. For example, if the Fund has hedged
against the possibility of an increase in interest rates which would adversely
affect the price of securities in its portfolio and the price of such securities
increases instead, the Fund will lose part or all of the benefit of the
increased value of its securities because it will have offsetting losses in its
hedging positions. In addition, when hedging with instruments that require
variation margin payments, if the Fund has insufficient cash to meet daily
variation margin requirements, it may have to sell securities to meet such
requirements. Such sales of securities may, but will not necessarily, be at
increased prices which reflect the rising market. Thus, the Fund may have to
sell securities at a time when it is disadvantageous to do so.

         The ability of the Fund to engage in hedging transactions may be
limited by tax considerations.

         New options and futures contracts and other financial products, and
various combinations thereof, continue to be developed, and the Fund may invest
in any such options, contracts and products as may be developed to the extent
consistent with the Fund's investment objective and the regulatory requirements
applicable to investment companies, and subject to the supervision of the
Trust's Board of Trustees.

   
VARIABLE AND FLOATING RATE INSTRUMENTS
    

   
         Certain obligations purchased by some of the Funds may carry variable
or floating rates of interest, may involve a conditional or unconditional
demand feature and may include variable amount master demand notes.
    

   
         Variable amount master demand notes are demand notes that permit the 
indebtedness thereunder to vary and provide for periodic adjustments in the
interest rate according to the terms of the instrument. Because master demand
notes are direct lending arrangements between a Fund and the issuer, they are
not normally traded. Although there is no secondary market in the notes, a Fund
may demand payment of principal and accrued interest at any time. While the
notes are not typically rated by credit rating agencies, issuers of variable
amount master demand notes (which are normally manufacturing, retail,
financial, and other business concerns) must satisfy the same criteria as set
forth above for commercial paper. Banc One Advisers or the Sub-Advisor will
consider the earning power, cash flow, and other liquidity ratios of the
issuers of such notes and will continuously monitor their financial status and
ability to meet payment on demand. In determining average weighted portfolio
maturity, a variable amount master demand note will be deemed to have a
maturity equal to the period of time remaining until the principal amount can
be recovered from the issuer through demand.
    

   
         Some of the Funds subject to their investment objective policies and
restrictions, may acquire variable and floating rate instuments. A variable 
rate instrument is one whose terms provide for the adjustment of its interest
rate on set dates and which, upon such adjustment, can reasonably be expected
to have a market value that approximates its par value. A floating rate
instrument is one whose terms provide for the adjustment of its interest rate
whenever a specified interest rate changes and which, at any time, can
reasonably be expected to have a market value that approximates its par value.
Such instrument are frequently not rated by credit rating agencies; however,
unrated variable and floating rate instruments purchased by a Fund will be
determined by Banc One Advisors or the Sub-Advisor under guidelines established
by the Trust's Board of Trustees to be of comparable quality at the time of
purchase to rated instruments eligible for purchase under the Fund's investment
policies. In making such determinations, Banc One Advisors or the Sub-Advisor
will consider the earning power, cash flow and other liquidity ratios of the
issuers of such instruments (such issuers include financial, merchandising,
bank holding and other companies) and will continuously monitor their financial
condition. Although there may be no active secondary market with respect to a
particular variable or floating rate instrument purchased by a Fund, the Fund
may re-sell the instrument at any time to a third party. The absence of such an
active secondary market, however, could make it difficult for the Fund to
dispose of the variable or floating rate instrument involved in the event the
issuer of the instrument defaulted on its payment obligations, and the Fund
could, for this or other reasons, suffer a loss to the extent of the default.
Variable or floating rate instruments may be secured by bank letters of credit.
A Fund will purchase a variable or floating rate instrument to facilitate
portfolio liquidity or to permit investment of the Fund's assets at a favorable
rate of return.
    

   
         Variable or floating rate instruments with stated maturities of more 
than 397 days may, under the Securities and Exchange Commission's amortized 
cost rule, Rule 2a-7 under the 1940 Act, be deemed to have shorter maturities 
as follows:
    

         (1) Adjustable Rate Government Securities. A Government Security which
is a Variable Rate Security where the variable rate of interest is readjusted no
less frequently than every 762 days shall be deemed to have a maturity equal to
the period remaining until the next readjustment of the interest rate. A
Government Security which is a Floating Rate Security shall be deemed to have a
remaining maturity of one day.

         (2) Short-Term Variable Rate Securities. A Variable Rate Security, the
principal amount of which, in accordance with the terms of the security, must
unconditionally be paid in 397 calendar days or less shall be deemed to have
maturity equal to the earlier of the period remaining until the next
readjustment of the interest rate or the period remaining until the principal
amount can be recovered through demand.

         (3) Long-Term Variable Rate Securities. A Variable Rate Security, the
principal amount of which is scheduled to be paid in more than 397 days, that is
subject to a Demand Feature shall be deemed to have a maturity equal to the
longer of the period remaining until the next readjustment of the interest rate
or the period remaining until the principal amount can be recovered through
demand.

         (4) Short-Term Floating Rate Securities. A Floating Rate Security, the
principal amount of which, in accordance with the terms of the security, must
unconditionally be paid in 397 calendar days or less shall be deemed to have a
maturity of one day.

         (5) Long-Term Floating Rate Securities. A Floating Rate Security, the
principal amount of which is scheduled to be paid in more than 397 days, that is
subject to a demand feature, shall be deemed to have a maturity equal to the
period remaining until the principal amount can be recovered through demand.

         As used above, a note is "subject to a demand feature" where the Fund
is entitled to receive the principal amount of the note either at any time on no
more than thirty days' notice or at specified intervals not exceeding 397
calendar days and upon no more than 30 days notice.

   
         Variable and floating rate instruments for which no readily available 
market exists will be purchased in an amount which, together with securities
with legal or contractual restrictions on resale or for which no readily
available market exists (including repurchase agreements providing for
settlement more than seven days after notice), exceeds 10% (with respect to the
Money Market and Institutional Money Market Funds) or 15% (with respect to all
Funds, other than the Money Market and Institutional Money Market Funds, which
can purchase such notes) of the Fund's net assets only if such instruments are
subject to a demand feature that will permit the Fund to demand payment of the
principal within seven days after demand by the Fund. There is no limit on the
extent to which a Fund may purchase demand instruments that are not illiquid.
If not rated, such instruments must be found by Banc One Advisors or the
Sub-Advisor, under guidelines established by the Trust's Board of Trustees, to
be of comparable quality to instruments that are rated high quality. A rating
may be relied upon only if it is provided by a nationally recognized
statistical rating organization that is not affiliated with the issuer or
guarantor of the instruments. For a description of the rating symbols of S&P,
Moody's, and Fitch used in this paragraph, see the Appendix. The above Funds
may also invest in Canadian Commercial Paper which is commercial paper issued
by a Canadian corporation or a Canadian counterpart of a U.S. corporation and
in Europaper which is U.S. dollar denominated commercial paper of a foreign
issuer.
    

MUNICIPAL SECURITIES

         As a matter of fundamental policy, under normal market conditions, at
least 80% of the total assets (net assets in the case of the Louisiana Municipal
Bond Fund) of each of the Municipal Money Market Fund, the Ohio Municipal Money
Market Fund, the Municipal Income Fund, the Intermediate Tax-Free Bond Fund, the
Ohio Municipal Bond Fund, the Texas Tax-Free Bond Fund, the Kentucky Municipal
Bond Fund, the Louisiana Municipal Bond Fund, the West Virginia Municipal Bond
Fund, the Arizona Municipal Bond Fund, and the Tax Exempt Money Market Fund will
be invested in Municipal Securities. Other Funds may also invest in Municipal
Securities if Banc One Advisors determines that such Municipal Securities offer
attractive yields. Municipal Securities are issued to obtain funds for various
public purposes, including the construction of a wide range of public facilities
such as bridges, highways, roads, schools, water and sewer works, and other
utilities. Other public purposes for which Municipal Securities may be issued
include refunding outstanding obligations, obtaining funds for general operating
expenses and obtaining funds to lend to other public institutions and
facilities. In addition, certain debt obligations known as "private activity
bonds" may be issued by or on behalf of municipalities and public authorities to
obtain funds to provide certain water, sewage and solid waste facilities,
qualified residential rental projects, certain local electric, gas and other
heating or cooling facilities, qualified hazardous waste facilities, high-speed
intercity rail facilities, governmentally-owned airports, docks and wharves and
mass commuting facilities, certain qualified mortgages, student loan and
redevelopment bonds and bonds used for certain organizations exempt from federal
income taxation. Certain debt obligations known as "industrial development
bonds" under prior federal tax law may have been issued by or on behalf of
public authorities to obtain funds to provide certain privately operated housing
facilities, sports facilities, industrial parks, convention or trade show
facilities, airport, mass transit, port or parking facilities, air or water
pollution control facilities, sewage or solid waste disposal facilities, and
certain facilities for water supply. Other private activity bonds and industrial
development bonds issued to fund the construction, improvement, equipment or
repair of privately-operated industrial, distribution, research, or commercial
facilities may also be Municipal Securities, but the size of such issues is
limited under current and prior federal tax law. The aggregate amount of most
private activity bonds and industrial development bonds is limited (except in
the case of certain types of facilities) under federal tax law by an annual
"volume

                                       23
<PAGE>   269
cap." The volume cap limits the annual aggregate principal amount of such
obligations issued by or on behalf of all governmental instrumentalities in the
state. The Tax-Free Funds may not be a desirable investment for "substantial
users" of facilities financed by private activity bonds or industrial
development bonds or for "related persons" of substantial users.

         Private activity bonds that are issued by or on behalf of public
authorities to finance various privately-operated facilities are included within
the term "Municipal Securities" as used in the Prospectuses of the
Tax-Advantaged Funds (other than the Municipal Money Market Fund) and in this
Statement of Additional Information with respect to such Funds only if the
interest paid thereon is both exempt from federal income tax and not treated as
a preference item for individuals for purposes of the federal alternative
minimum tax. Private activity bonds that are subject to federal income tax and
are treated as a preference item for individuals for purposes of the federal
alternative minimum tax are included within the term "Taxable Obligations" as
used in the Prospectuses of the Tax-Advantaged Funds (other than the Ohio
Municipal Money Market Fund, the Ohio Municipal Bond Fund and Municipal Money
Market Fund). As used in the Prospectuses of the Ohio Municipal Money Market
Fund, the Ohio Municipal Bond Fund and the Municipal Money Market Fund and in
this Statement of Additional Information with respect to such Funds, the term
Municipal Securities includes private activity bonds that are issued by or on
behalf of public authorities to finance privately operated facilities only if
the interest paid thereon is exempt from federal income tax (other than the
Federal alternative minimum tax). Private activity bonds that are subject to
federal income tax are included within the term Taxable Obligations as used in
the Prospectuses of the Ohio Municipal Money Market Fund, the Ohio Municipal
Bond Fund, and the Municipal Money Market Fund. The payment of principal and
interest on private activity bonds generally is dependent solely on the ability
of the facility users to meet its financial obligations and the pledge, if any,
of real and personal property as security for said payment.

         The two principal classifications of Municipal Securities consist of
"general obligation" and "limited" (or revenue) issues. General obligation bonds
are obligations involving the credit of an issuer possessing taxing power and
are payable from the issuer's general unrestricted revenues and not from any
particular fund or source. The characteristics and method of enforcement of
general obligation bonds vary according to the law applicable to the particular
issuer, and payment may be dependent upon appropriation by the issuer's
legislative body. Limited obligation bonds are payable only from the revenues
derived from a particular facility or class of facilities or, in some cases,
from the proceeds of a special excise or other specific revenue source. Private
activity bonds and industrial development bonds generally are revenue bonds and
thus not payable from the unrestricted revenues of the issuer. The credit and
quality of such bonds is generally related to the credit of the bank selected to
provide the letter of credit underlying the bond. Payment of principal of and
interest on industrial development revenue bonds is the responsibility of the
corporate user (and any guarantor).

         The Funds may also acquire "moral obligation" issues, which are
normally issued by special purpose authorities, and in other tax-exempt
investments including pollution control bonds and tax-exempt commercial paper.
Each Fund may purchase short-term tax-exempt General Obligations Notes, Tax
Anticipation Notes, Bond Anticipation Notes, Revenue Anticipation Notes, Project
Notes, and other forms of short-term tax-exempt loans. Such notes are issued
with a short-term maturity in anticipation of the receipt of tax funds, the
proceeds of bond placements, or other revenues. Project Notes are issued by a
state or local housing agency and are sold by the Department of Housing and
Urban Development. While the issuing agency has the primary obligation with
respect to its Project Notes, they are also secured by the full faith and credit
of the United States through agreements with the issuing authority which provide
that, if required, the federal government will lend the issuer an amount equal
to the principal of and interest on the Project Notes.

         There are, of course, variations in the quality of Municipal
Securities, both within a particular classification and between classifications,
and the yields on Municipal Securities depend upon a variety of factors,
including general money market conditions, the financial condition of the
issuer, general conditions of the municipal bond market, the size of a
particular offering, the maturity of the obligations, and the rating of the
issue. The ratings of Moody's and S&P represent their opinions as to the quality
of Municipal Securities. It should be emphasized, however, that ratings are
general and are not absolute standards of quality, and Municipal Securities with
the same maturity, interest rate and rating may have different yields while
Municipal Securities of the same maturity and interest rate with different
ratings may have the same yield. Subsequent to its purchase by a Fund, an issue
of Municipal Securities may cease to be rated or its rating may be reduced below
the minimum rating required for purchase by the Fund. Banc One Advisors will
consider such an event in determining whether the Fund should continue to hold
the obligations.

         Municipal securities may include obligations of municipal housing
authorities and single-family mortgage revenue bonds. Weaknesses in Federal
housing subsidy programs and their administration may result in a decrease of
subsidies available for payment of principal and interest on housing authority
bonds. Economic developments, including fluctuations in interest rates and
increasing construction and operating costs, may also adversely impact revenues
of housing authorities. In the case of some housing authorities, inability to
obtain additional financing could also reduce revenues available to pay existing
obligations. Single-family mortgage revenue bonds are subject to extraordinary
mandatory redemption at par in whole or in part from the proceeds derived from
prepayments of underlying mortgage loans and also from the unused proceeds of
the issue within a stated period which may be within a year from the date of
issue.


                                       24
<PAGE>   270
         Municipal leases are obligations issued by state and local governments
or authorities to finance the acquisition of equipment and facilities and may be
considered to be illiquid. They may take the form of a lease, an installment
purchase contract, a conditional sales contract, or a participation interest in
any of the above. Each Fund will limit its investment in municipal leases to no
more than 5% of its total assets. The Board of Trustees is responsible for
determining the credit quality of unrated municipal leases, on an ongoing basis,
including an assessment of the likelihood that the lease will not be cancelled.

         The exclusion from gross income for Federal income tax purposes for
certain housing authority bonds depends on qualification under relevant
provisions of the Code and on other provisions of Federal law. These provisions
of Federal law contain certain ongoing requirements relating to the cost and
location of the residences financed with the proceeds of the single-family
mortgage bonds and the income levels of tenants of the rental projects financed
with the proceeds of the multi-family housing bonds. While the issuers of the
bonds, and other parties, including the originators and servicers of the
single-family mortgages and the owners of the rental projects financed with the
multi-family housing bonds, covenant to meet these ongoing requirements and
generally agree to institute procedures designed to insure that these
requirements will be consistently met, there is no assurance that the
requirements will be consistently met. The failure to meet these requirements
could cause the interest on the bonds to become taxable, possibly retroactively
from the date of issuance, thereby reducing the value of the bonds and
subjecting Shareholders to unanticipated tax liabilities and possibly requiring
a Fund to sell the bonds at the reduced value. Furthermore, any failure to meet
these ongoing requirements might constitute an event of default under the
applicable mortgage or permit the holder to accelerate payment of the bond or
require the issuer to redeem the bond. In any event, where the mortgage is
insured by the Federal Housing Administration ("FHA"), the consent of the FHA
may be required before insurance proceeds would become payable to redeem the
mortgage subsidy bonds.

         Information about the financial condition of issuers of Municipal
Securities may be less available than about corporations having a class of
securities registered under the Securities Exchange Act of 1934.

         An issuer's obligations under its Municipal Securities are subject to
the provisions of bankruptcy, insolvency, and other laws affecting the rights
and remedies of creditors, such as the federal bankruptcy code, and laws, if
any, which may be enacted by Congress or state legislatures extending the time
for payment of principal or interest, or both, or imposing other constraints
upon the enforcement of such obligations. The power or ability of an issuer to
meet its obligations for the payment of interest on and principal of its
Municipal Securities may be materially adversely affected by litigation or other
conditions.

         Such litigation or conditions may from time to time have the effect of
introducing uncertainties in the market for tax-exempt obligations or certain
segments thereof, or may materially affect the credit risk with respect to
particular bonds or notes. Adverse economic, business, legal or political
developments might affect all or a substantial portion of a Fund's Municipal
Securities in the same manner.

         From time to time, proposals have been introduced before Congress for
the purpose of restricting or eliminating the federal income tax exemption for
interest on tax exempt bonds, and similar proposals may be introduced in the
future. A recent decision of the United States Supreme Court has held that
Congress has the constitutional authority to enact such legislation. It is not
possible to determine what effect the adoption of such proposals could have on
(i) the availability of Municipal Securities for investment by the Funds, and
(ii) the value of the investment portfolios of the Funds.

         The Internal Revenue Code of 1986, as amended (the "Code") imposes
certain continuing requirements on issuers of tax-exempt bonds regarding the
use, expenditure and investment of bond proceeds and the payment of rebates to
the United States of America. Failure by the issuer to comply subsequent to the
issuance of tax-exempt bonds with certain of these requirements could cause
interest on the bonds to become includable in gross income retroactive to the
date of issuance.

         The Funds may invest in Municipal Securities either by purchasing them
directly or by purchasing certificates of accrual or similar instruments
evidencing direct ownership of interest payments or principal payments, or both,
on Municipal Securities, provided that, in the opinion of counsel to the initial
seller of each such certificate or instrument, any discount accruing on such
certificate or instrument that is purchased at a yield not greater than the
coupon rate of interest on the related Municipal Securities will to the same
extent as interest on such Municipal Securities be exempt from federal income
tax and state income tax (where applicable) and not treated as a preference item
for individuals for purposes of the federal alternative minimum tax. The Funds
may also invest in Municipal Securities by purchasing from banks participation
interests in all or part of specific holdings of Municipal Securities. Such
participation may be backed in whole or in part by an irrevocable letter of
credit or guarantee of the selling bank. The selling bank may receive a fee from
a Fund in connection with the arrangement. A Fund will not purchase
participation interests unless it receives an opinion of counsel or a ruling of
the Internal Revenue Service that interest earned by it on Municipal Securities
in which it holds such participation interest is exempt from federal income tax
and state income tax (where applicable) and not treated as a preference item for
individuals for purposes of the federal alternative minimum tax.

DEMAND FEATURES

         The Funds (except the Funds of Funds and the Treasury & Agency Fund)
may acquire securities that are subject to puts and standby commitments ("demand
features") to purchase the securities at their principal amount (usually with
accrued interest) within a fixed period (usually seven days) following a demand
by the Fund. The demand feature may be issued by the issuer of the underlying
securities, a dealer in the securities or by another third party, and may not be
transferred separately from the underlying security. The underlying securities
subject to a put may be sold at any time at market rates. The Funds expect that
they will acquire puts only where the puts are available without the payment of
any direct or indirect consideration. However, if advisable or necessary, a
premium may be paid for put features. A premium paid will have the effect of
reducing the yield otherwise payable on the underlying security.

         Under a "stand-by commitment," a dealer would agree to purchase, at a
Fund's option, specified municipal securities at a specified price. A Fund will
acquire these commitments solely to facilitate portfolio liquidity and does not
intend to exercise its rights thereunder for trading purposes. Stand-by
commitments may also be referred to as put options. A Fund will generally limit
its investments in stand-by commitments to 25% of its total assets.

         The purpose of engaging in transactions involving puts is to maintain
flexibility and liquidity to permit the Fund to meet redemption requests and
remain as fully invested as possible.

SWAPS, CAPS AND FLOORS

         Certain of the Funds may enter into swaps, caps, and floors on various
securities (such as U.S. government securities), securities indexes, interest
rates, prepayment rates, foreign currencies or other financial instruments or
indexes, in order to protect the value of the Fund from interest rate
fluctuations and to hedge against fluctuations in the floating rate market in
which the Fund's investments are traded, for both hedging and non-hedging
purposes. While swaps, caps, and floors (sometimes hereinafter collectively
referred to as "swap contracts") are different from futures contracts (and
options on futures contracts) in that swap contracts are individually negotiated
with specific counterparties, the Funds will use swap contracts for purposes
similar to the purposes for which they use options, futures, and options on
futures. Those uses of swap contracts (i.e., risk management and hedging)
present the Funds with risks and opportunities similar to those associated with
options contracts, futures contracts, and options on futures. See "Futures
Contracts" and "Risk Factors in Futures Contracts."

         The Funds may enter into these transactions to manage their exposure to
changing interest rates and other market factors. Some transactions may reduce
each Fund's exposure to market fluctuations while others may tend to increase
market exposure.

         Swap contracts typically involve an exchange of obligations by two
sophisticated parties. For example, in an interest rate swap, the Fund may
exchange with another party their respective rights to receive interest, such as
an exchange of fixed rate payments for floating rate payments. Currency swaps
involve the exchange of respective rights to make or receive payments in
specified currencies. Mortgage swaps are similar to interest rate swaps in that
they represent commitments to pay and receive interest. The notional principal
amount, however, is tied to a reference pool or pools of mortgages.

         Caps and floors are variations on swaps. The purchase of a cap entitles
the purchaser to receive a principal amount from the party selling the cap to
the extent that a specified index exceeds a predetermined interest rate or
amount. The purchase of an interest rate floor entitles the purchaser to receive
payments on a notional principal amount from the party selling the floor to the
extent that a specified index falls below a predetermined interest rate or
amount. Caps and floors are similar in many respects to over-the-counter options
transactions, and may involve investment risks that are similar to those
associated with options transactions and options on futures contracts.

         Because swap contracts are individually negotiated, they remain the
obligation of the respective counterparties, and there is a risk that a
counterparty will be unable to meet its obligations under a particular swap
contract. If a counterparty defaults on a swap contract with a Fund, the Fund
may suffer a loss. To address this risk, each Fund will usually enter into
interest rate swaps on a net basis, which means that the two payment streams
(one from the Fund to the counterparty, one to the Fund from the counterparty)
are netted out, with the Fund receiving or paying, as the case may be, only the
net amount of the two payments. Interest rate swaps do not involve the delivery
of securities, other underlying assets, or principal, except for the purposes of
collateralization as discussed below. Accordingly, the risk of loss with respect
to interest rate swaps entered into on a net basis would be limited to the net
amount of the interest payments that the Fund is contractually obligated to
make. If the other party to an interest rate swap defaults, the Fund's risk of
loss consists of the net amount of interest payments that a Fund is
contractually entitled to receive. In addition, the Fund may incur a market
value adjustment on securities held upon the early termination of the swap. To
protect against losses related to counterparty default, the Funds may enter into
swaps that require transfers of collateral for changes in market value. In
contrast, currency swaps and other types of swaps may involve the delivery of
the entire principal value of one designated currency or financial instrument in


                                       26
<PAGE>   272
exchange for the other designated currency or financial instrument. Therefore,
the entire principal value of such swaps may be subject to the risk that the
other party will default on its contractual delivery obligations.

         In addition, because swap contracts are individually negotiated and
ordinarily non-transferable, there also may be circumstances in which it would
be impossible for a Fund to close out its obligations under the swap contract
prior to its maturity. Under such circumstances, the Fund might be able to
negotiate another swap contract with a different counterparty to offset the risk
associated with the first swap contract. Unless the Fund is able to negotiate
such an offsetting swap contract, however, the Fund could be subject to
continued adverse developments, even after Banc One Advisors has determined that
it would be prudent to close out or offset the first swap contract.

         The Funds will not enter into any mortgage swap, interest rate swap,
cap or floor transaction unless the unsecured commercial paper, senior debt, or
the claims paying ability of the other party thereto is rated in one of the top
two rating categories by at least one NRSRO, or if unrated, determined by Banc
One Advisors to be of comparable quality.

         The use of swaps involves investment techniques and risks different
from and potentially greater than those associated with ordinary Fund securities
transactions. If Banc One Advisors is incorrect in its expectations of market
values, interest rates, or currency exchange rates, the investment performance
of the Funds would be less favorable than it would have been if this investment
technique were not used. In addition, in certain circumstances entry into a swap
contract that substantially eliminates risk of loss and the opportunity for gain
in an "appreciated financial position" will accelerate gain to the Funds.

         The Staff of the Securities and Exchange Commission is presently
considering its position with respect to swaps, caps and floors as senior
securities. Pending a determination by the Staff, the Funds will either treat
swaps, caps and floors as being subject to their senior securities restrictions
or will refrain from engaging in swaps, caps and floors. Once the Staff has
expressed a position with respect to swaps, caps and floors, the Funds intend to
engage in swaps, caps and floors, if at all, in a manner consistent with such
position. To the extent the net amount of an interest rate or mortgage swap is
held in a segregated account, consisting of cash or liquid, high grade debt
securities, the Funds and Banc One Advisors believe that swaps do not constitute
senior securities under the Investment Company Act of 1940 and, accordingly,
will not treat them as being subject to each Fund's borrowing restrictions. The
net amount of the excess, if any, of each Fund's obligations over its
entitlements with respect to each interest rate swap will be accrued on a daily
basis and an amount of cash or liquid securities having an aggregate net asset
value at least equal to the accrued excess will be maintained in a segregated
account by the Funds' Custodian. Each of the Bond Funds generally will limit
their investments in swaps, caps and floors to 25% of its total assets.

STRUCTURED INSTRUMENTS

         Structured instruments are debt securities issued by agencies of the
U.S. government (such as Ginnie Mae, Fannie Mae, and Freddie Mac), banks,
corporations, and other business entities whose interest and/or principal
payments are indexed to certain specific foreign currency exchange rates,
interest rates, or one or more other reference indices. Structured instruments
frequently are assembled in the form of medium-term notes, but a variety of
forms are available and may be used in particular circumstances. Structured
instruments are commonly considered to be derivatives.

         The terms of such structured instruments provide that their principal
and/or interest payments are adjusted upwards or downwards to reflect changes in
the reference index while the structured instruments are outstanding. In
addition, the reference index may be used in determining when the principal is
redeemed. As a result, the interest and/or principal payments that may be made
on a structured product may vary widely, depending on a variety of factors,
including the volatility of the reference index and the effect of changes in the
reference index on principal and/or interest payment.

         While structured instruments may offer the potential for a favorable
rate of return from time to time, they also entail certain risks. Structured
instruments may be less liquid than other debt securities, and the price of
structured instruments may be more volatile. If the value of the reference index
changes in a manner other than that expected by Banc One Advisors, principal
and/or interest payments on the structured instrument may be substantially less
than expected. The Funds will invest only in structured securities that are
consistent with each Fund's investment objective, policies and restrictions and
Banc One Advisors' outlook on market conditions. In some cases, depending on the
terms of the reference index, a structured instrument may provide that the
principal and/or interest payments may be adjusted below zero; however, the
Funds will not invest in structured instruments if the terms of the structured
instrument provide that the Funds may be obligated to pay more than their
initial investment in the structured instrument, or to repay any interest or
principal that has already been collected or paid back. Structured instruments
that are registered under the federal securities laws may be treated as liquid.
In addition, many structured instruments may not be registered under the federal
securities laws. In that event, a Fund's ability to resell such a structured
instrument may be more limited than its ability to resell other Fund securities.
The Funds will treat such instruments as illiquid, and will limit their
investments in such instruments to no more than 15% of each Fund's net assets,
when combined with all other illiquid investments of each Fund. In addition,
although structured instruments may be sold


                                       27
<PAGE>   273
in the form of a corporate debt obligation, they may not have some of the
protection against counterparty default that may be available with respect to
publicly traded debt securities (i.e., the existence of a trust indenture). In
that respect, the risks of default associated with structured instruments may be
similar to those associated with swap contracts. See "Swaps, Caps and Floors."

NEW FINANCIAL PRODUCTS

         New options and futures contracts and other financial products, and
various combinations thereof, continue to be developed and certain of the Funds
may invest in any such options, contracts and products as may be developed to
the extent consistent with each Fund's investment objective, policies and
restrictions and the regulatory requirements applicable to investment companies.

         These various products may be used to adjust the risk and return
characteristics of each Fund's investments. These various products may increase
or decrease exposure to security prices, interest rates, commodity prices, or
other factors that affect security values, regardless of the issuer's credit
risk. If market conditions do not perform consistent with expectations, the
performance of each Fund would be less favorable than it would have been if
these products were not used. In addition, losses may occur if counterparties
involved in transactions do not perform as promised. These products may expose
the Fund to potentially greater return as well as potentially greater risk of
loss than more traditional fixed income investments.

RESTRICTED SECURITIES

         Some of the Funds may invest in commercial paper issued in reliance on
the exemption from registration afforded by Section 4(2) of the Securities Act
of 1933 and other restricted securities. Section 4(2) commercial paper is
restricted as to disposition under federal securities law and is generally sold
to institutional investors, such as the Funds, who agree that they are
purchasing the paper for investment purposes and not with a view to public
distribution. Any resale by the purchaser must be in an exempt transaction.
Section 4(2) commercial paper is normally resold to other institutional
investors like the Funds through or with the assistance of the issuer or
investment dealers who make a market in Section 4(2) commercial paper, thus
providing liquidity. The Funds believe that Section 4(2) commercial paper and
possibly certain other restricted securities which meet the criteria for
liquidity established by the Trustees are quite liquid. The Funds intend,
therefore, to treat restricted securities that meet the liquidity criteria
established by the Board of Trustees, including Section 4(2) commercial paper
and Rule 144A Securities, as determined by Banc One Advisors, as liquid and not
subject to the investment limitation applicable to illiquid securities.

         The ability of the Trustees to determine the liquidity of certain
restricted securities is permitted under a Securities and Exchange Commission
("SEC") Staff position set forth in the adopting release for Rule 144A under the
Securities Act of 1933 (the "Rule"). The Rule is a nonexclusive safe-harbor for
certain secondary market transactions involving securities subject to
restrictions on resale under federal securities laws. The Rule provides an
exemption from registration for resales of otherwise restricted securities to
qualified institutional buyers. The Rule was expected to further enhance the
liquidity of the secondary market for securities eligible for resale under Rule
144A. The Funds believe that the Staff of the SEC has left the question of
determining the liquidity of all restricted securities to the Trustees. The
Trustees have directed Banc One Advisors to consider the following criteria in
determining the liquidity of certain restricted securities:

         -        the frequency of trades and quotes for the security;

         -        the number of dealers willing to purchase or sell the security
                  and the number of other potential buyers;

         -        dealer undertakings to make a market in the security; and

         -        the nature of the security and the nature of the marketplace
                  trades.

         Certain Section 4(2) commercial paper programs cannot rely on Rule 144a
because, among other things, they were established before the adoption of the
rule. However, the Trustees may determine for purposes of the Trust's liquidity
requirements that an issue of 4(2) commercial paper is liquid if the following
conditions, which are set forth in a 1994 SEC no-action letter, are met:

         -        The 4(2) paper must not be traded flat or in default as to
                  principal or interest;

         -        The 4(2) paper must be rated in one of the two highest rating
                  categories by a least two nationally recognized statistical
                  rating organizations ("NRSROs"), or if only one NRSRO rates
                  the security, by that NRSRO, or if unrated, is determined by
                  Banc One Advisors to be of equivalent quality; and


                                       28
<PAGE>   274
         -        Banc One Advisors must consider the trading market for the
                  specific security, taking into account all relevant factors,
                  including but not limited, to whether the paper is the subject
                  of a commercial paper program that is administered by an
                  issuing and paying agent bank and for which there exists a
                  dealer willing to make a market in that paper, or is
                  administered by a direct issuer pursuant to a direct placement
                  program; and

         -        Banc One Advisors shall monitor the liquidity of the 4(2)
                  commercial paper purchased and shall report to the Board of
                  Trustees promptly if any such securities are no longer
                  determined to be liquid if such determination causes a fund to
                  hold more than 15% (10% for Money Market Funds) of its net
                  assets in illiquid securities in order for the Board of
                  Trustees to consider what action, if any, should be taken on
                  behalf of The One Group, unless Banc One Advisors is able to
                  dispose of illiquid assets in an orderly manner in an amount
                  that reduces the Fund's holdings of illiquid assets to less
                  than 15% (10% for Money Market Funds) of its net assets; and

         -        Banc One Advisors shall report to the Board of Trustees on the
                  appropriateness of the purchase and retention of liquid
                  restricted securities under these Guidelines no less
                  frequently that quarterly.

HIGH YIELD SECURITIES

         The Income Fund and the Income Bond Fund may invest in high yield
securities. High yield bonds are securities that are rated below investment
grade by the primary rating agencies (BB or lower by S&P and BA or lower by
Moody's). Other terms used to describe such securities include "lower rated
bonds", "non-investment grade bonds" and "junk bonds". Generally, lower rated
debt securities provide a higher yield than higher rated debt securities of
similar maturity, but are subject to a greater degree of risk with respect to
the ability of the issuer to meet its principal and interest obligations.
Issuers of high yield securities may not be as strong financially as those
issuing higher rated securities. These securities are regarded as predominately
speculative. The market value of high yield securities may fluctuate more than
the market value of higher rated securities, since high yield securities tend to
reflect short-term corporate and market developments to a greater extent than
higher rated securities, which fluctuate primarily in response to the general
level of interest rates, assuming that there has been no change in the
fundamental quality of such securities. The market prices of fixed income
securities generally fall when interest rates rise. Conversely, the market
prices of fixed-income securities generally rise when interest rates fall.

         Additional risks of high yield securities include limited liquidity and
secondary market support. As a result, the prices of high yield securities may
decline rapidly in the event that a significant number of holders decide to
sell. Changes in expectations regarding an individual issuer, an industry or
high yield securities generally could reduce market liquidity for such
securities and make their sale by the Funds more difficult, at least in the
absence of price concessions. Reduced liquidity also could adversely affect the
Funds' ability to accurately value high yield securities. Issuers of high yield
securities also are more vulnerable to real or perceived economic changes (for
instance, an economic downturn or prolonged period of rising interest rates),
political changes or adverse developments specific to the issuer. Adverse
economic, political or other developments may impair the issuer's ability to
service principal and interest obligations, to meet projected business goals and
to obtain additional financing, particularly if the issuer is highly leveraged.
In the event of a default, the Funds would experience a reduction of their
income and could expect a decline in the market value of the defaulted
securities.

         Further, proposed or yet to be proposed new laws may have a possible
negative impact on the market for high yield bonds. As an example, legislation
required federally-insured savings and loan associations to divest their
investments in high yield bonds. New legislation, if enacted, could have a
material negative effect on a Fund's net asset value and investment practices.

         Finally, the market prices of high-yield securities structured as zero
coupon or pay-in-kind securities are generally affected to a greater extent by
interest rate changes and tend to be more volatile than securities which pay
interest periodically. In addition, zero coupon, pay-in-kind and delayed
interest bonds often do not pay interest until maturity. Accordingly, such bonds
may involve greater credit risks than bonds paying interest currently. However,
a Fund must recognize a computed amount of interest income and pay dividends to
shareholders even though it has received no cash. In some instances, the Funds
may have to sell securities to have sufficient cash to pay the dividends.

         The high yield securities in which the Funds may invest include the
         following:

         -- Straight fixed-income debt securities. These include bonds and other
         debt obligations which bear a fixed or variable rate of interest
         payable at regular intervals and have a fixed or resettable maturity
         date. The particular terms of such securities vary and may include
         features such as call provisions and sinking funds.

         -- Zero-coupon debt securities. These bear no interest obligation but
         are issued at a discount from their value at maturity. When held to
         maturity, their entire return equals the difference between their issue
         price and their maturity value.


                                       29
<PAGE>   275
         -- Zero-fixed-coupon debt securities. These are zero-coupon debt
         securities which convert on a specified date to interest-bearing debt
         securities.

         -- Pay-in-kind bonds. These are bonds which allow the issuer, at its
         option, to make current interest payments on the bonds either in cash
         or in additional bonds.

U.S. TREASURY OBLIGATIONS

         The Funds may invest in bills, notes and bonds issued by the U.S.
Treasury and separately traded interest and principal component parts of such
obligations that are transferable through the Federal book-entry system known as
Separately Traded Registered Interest and Principal Securities ("STRIPS") and
Coupon Under Book Entry Safekeeping ("CUBES").

TREASURY RECEIPTS

         Certain of the Funds may purchase interests in separately traded
interest and principal component parts of U.S. Treasury obligations that are
issued by banks or brokerage firms and are created by depositing U.S. Treasury
notes and U.S. Treasury bonds into a special account at a custodian bank.
Receipts include Treasury Receipts ("TRS"), Treasury Investment Growth Receipts
("TIGRS"), and Certificates of Accrual on Treasury Securities ("CATS").

COMMON STOCK

         Common stock represents a share of ownership in a company and usually
carries voting rights and earns dividends. Unlike preferred stock, dividends on
common stock are not fixed but are declared at the discretion of the issuer's
board of directors.

PREFERRED STOCK

         Preferred stock is a class of stock that generally pays dividends at a
specified rate and has preference over common stock in the payment of dividends
and liquidation. Preferred stock generally does not carry voting rights. As with
all equity securities, the price of preferred stock fluctuates based on changes
in a company's financial condition and on overall market and economic
conditions.

INVESTMENT COMPANY SECURITIES

         Some of the Funds may invest up to 5% of their total assets in the
securities of any one investment company, but may not own more than 3% of the
securities of any one investment company or invest more than 10% of their total
assets in the securities of other investment companies. These limits do not
apply to the Fund of Funds. Other investment company securities may include
securities of a money market fund of the Trust, and securities of other
investment companies for which Banc One Advisors serves as investment advisor or
administrator. Because other investment companies employ an investment advisor,
such investments by the Funds may cause Shareholders to bear duplicative fees.
Banc One Advisors will waive its fee attributable to the assets of the investing
fund invested in a money market fund of the Trust and in other funds advised by
Banc One Advisors; and, to the extent required by the laws of any state in which
shares of the Trust are sold, Banc One Advisors will waive its fees attributable
to the assets of any Fund invested in any investment company.

CONVERTIBLE SECURITIES

         Convertible securities have characteristics similar to both fixed
income and equity securities. Convertible securities may be issued as bonds or
preferred stock. Because of the conversion feature, the market value of
convertible securities tends to move together with the market value of the
underlying stock. As a result, the Funds' selection of convertible securities is
based, to a great extent, on the potential for capital appreciation that may
exist in the underlying stock. The value of convertible securities is also
affected by prevailing interest rates, the credit quality of the issuer, and any
call provisions.

WARRANTS

         Warrants are securities, typically issued with preferred stock or
bonds, that give the holder the right to buy a proportionate amount of common
stock at a specified price, usually at a price that is higher than the market
price at the time of issuance of the warrant. The right may last for a period of
years or indefinitely.


                                       30
<PAGE>   276
ASSET-BACKED SECURITIES

         Asset-backed securities consist of securities secured by company
receivables, home equity loans, truck and auto loans, leases, credit card
receivables and other securities backed by other types of receivables or other
assets. These securities are generally pass-through securities, which means that
principal and interest payments on the underlying securities (less servicing
fees) are passed through to shareholders on a pro rata basis. These securities
involve prepayment risk, which is the risk that the underlying debt may be
refinanced or paid off prior to their maturities during periods of declining
interest rates. In that case, a portfolio manager may have to reinvest the
proceeds from the securities at a lower rate. Potential market gains on a
security subject to prepayment risk may be more limited than potential market
gains on a comparable security that is not subject to prepayment risk. Under
certain prepayment rate scenarios, the Fund may fail to recoup any premium paid
on asset-backed securities.

SHORT-TERM FUNDING AGREEMENT

         Some Funds may, in order to enhance yield, make limited investments in
short-term funding agreements issued by banks and highly rated U.S. insurance
companies. Short-term funding agreements issued by insurance companies are
sometimes referred to as Guaranteed Investment Contracts ("GICs"), while those
issued by banks are referred to as Bank Investment Contracts ("BICs"). Pursuant
to such agreements, the Funds make cash contributions to a deposit account at a
bank or insurance company. The bank or insurance company then credits to the
Funds on a monthly basis guaranteed interest at either a fixed, variable or
floating rate. These contracts are general obligations of the issuing bank or
insurance company (although they may be the obligations of an insurance company
separate account) and are paid from the general assets of the issuing entity.
The funds will purchase short-term funding agreements only from banks and
insurance companies which, at the time of purchase, are rated in one of the
three highest rating categories and have assets of $1 billion or more.
Generally, there is no active secondary market in short-term funding agreements.
Therefore, short-term funding agreements may be considered by the Funds to be
illiquid investments. To the extent that a short-term funding agreement is
determined to be illiquid, such agreements will be acquired by the Funds only
if, at the time of purchase, no more than 15% of the Fund's net assets will be
invested in short-term funding agreements and other illiquid securities.

OHIO MUNICIPAL SECURITIES

         As used in the Prospectuses and this Statement of Additional
Information, the term "Ohio Municipal Securities" refers to debt securities
which are issued by or on behalf of Ohio or its respective authorities,
agencies, instrumentalities and political subdivisions which produce interest
which, in the opinion of counsel for the issuer are exempt from both federal
income tax, and Ohio personal income tax.

Risk Factors Regarding Investments in Ohio Municipal Securities

         The economy of Ohio, while becoming increasingly diversified and
increasingly reliant on the service sector, continues to rely in significant
part on durable goods manufacturing, which is largely concentrated in motor
vehicles and equipment, steel, rubber products and household appliances. As a
result, general economic activity in Ohio, as in many other industrial states,
tends to be more cyclical than in some other states and in the nation as a
whole. Agriculture also is an important segment of the Ohio economy, and the
state has instituted several programs to provide financial assistance to
farmers. Although revenue obligations of the state or its political subdivisions
may be payable from a specific source or project, and general obligation debt
may be payable from a specific tax, there can be no assurance that future
economic difficulties and the resulting impact on state and local government
finances will not adversely affect the market value of the Ohio Municipal
Securities in the Funds of the Trust or the ability of the respective obligators
to make timely payment of interest and principal on such obligations.

         Since the Ohio Municipal Bond Fund and Ohio Municipal Money Market Fund
invest primarily in Ohio Municipal Securities, the value of each Fund's Shares
may be especially affected by factors pertaining to the economy of Ohio and
other factors specifically affecting the ability of issuers of Ohio Municipal
Securities to meet their obligations. As a result, the value of the Shares of
the Ohio Municipal Bond Fund and the Ohio Municipal Money Market Fund may
fluctuate more widely than the value of Shares of a portfolio investing in
securities relating to a number of different states. The ability of Ohio state,
county, or local governments to meet their obligations will depend primarily on
the availability of tax and other revenues to those governments and on their
fiscal conditions generally. The amounts of tax and other revenues available to
issuers of Ohio Municipal Securities may be affected from time to time by
economic, political and demographic conditions within the state. In addition,
constitutional or statutory restrictions may limit a government's power to raise
revenues or increase taxes. The availability of federal, state, and local aid to
issuers of Ohio Municipal Securities may also affect their ability to meet their
obligations. Payments of principal and interest on limited obligation securities
will depend on the economic condition of the facility or specific revenue source
from which revenues the payments will be made, which in turn could be affected
by economic, political, and demographic conditions in the state. Any reduction
in the actual or perceived ability to meet obligations on the part of either an
issuer of an Ohio Municipal Security or a provider of credit enhancement for
such Ohio

                                       31
<PAGE>   277
Municipal Security (including a reduction in the rating of its outstanding
securities) would likely affect adversely the market value and marketability of
that Ohio Municipal Security and could adversely affect the values of other Ohio
Municipal Securities as well.

WEST VIRGINIA MUNICIPAL SECURITIES

         As used in the Prospectus and this Statement of Additional Information,
the term "West Virginia Municipal Securities" refers to debt securities which
are issued by or on behalf of West Virginia or its respective authorities,
agencies, instrumentalities and political subdivisions and which produce
interest which, in the opinion of counsel for the issuer, is exempt from both
federal income tax and is generally exempt from West Virginia personal income
tax.

         Risk Factors Regarding Investments in West Virginia Municipal
Securities. Because of concentration of the West Virginia Fund's investments in
West Virginia municipal securities, the Fund is more subject to the risks of
West Virginia's economy than if the Fund was invested in municipal securities of
various states.

         Coal mining and related industries remain an important part of the West
Virginia economy, but increasing governmental regulation affecting production
and usage of coal and reduction in demand for certain types of coal have had an
adverse impact on the industry, state and local governments have made and
continue to make concentrated efforts to encourage diversification of the
state's economy with some success, such as the growth in tourism and the
location of a new Toyota plant in the state.

         While there has been progress in creating new jobs, West Virginia's
unemployment continues to exceed the national average. For May, 1997, West
Virginia's seasonally adjusted unemployment rate was 6.0% as compared to the
national average of 4.8%.

         Because of increased taxes since 1989, the State's current financial
position is relatively stable, and in recent years, there have been budget
surpluses at the end of the State's fiscal year. In addition, the completion of
the statewide reappraisal of property subject to ad valorem taxation in 1994 has
increased funding available to local governments and school boards. However,
with little or no population growth, unemployment remaining above the national
average in most of the state, the continuing decline in school enrollment and an
aging population, among other factors, the State, local governments and school
boards continue to struggle to produce sufficient revenues to fund operations
and support public education.


KENTUCKY MUNICIPAL SECURITIES

         As used in the Prospectus and this Statement of Additional Information,
the term "Kentucky Municipal Securities" refers to debt securities which are
issued by or on behalf of Kentucky or its respective authorities, agencies,
instrumentalities and political subdivisions and which produce interest which,
in the opinion of counsel for the issuer, is exempt from both federal income tax
and Kentucky personal income tax.

         Risk Factors Regarding Investments in Kentucky Municipal Securities. As
of May 31, 1997, Kentucky had an unemployment rate of 5.9%, which equaled the
national average. For calendar year 1996, Kentucky's per capita income ranked
42nd in the nation and was 81% of the national average. The most current audited
financial statements for Kentucky indicate a surplus of funds in the General
Fund of $503,200,000 as of June 30, 1996, which was $482,500,000 above the
budgeted balance.

         Unlike the municipal securities of most states, nearly all Kentucky
Municipal Securities are not general obligations of the issuer; rather, payment
depends on revenues generated by the property financed by the securities.

TEXAS MUNICIPAL SECURITIES

         As used in the Prospectus and this Statement of Additional Information,
the term "Texas Municipal Securities" refers to debt securities which are issued
by or on behalf of Texas or its respective authorities, agencies,
instrumentalities and political subdivisions and which produce interest which,
in the opinion of counsel for the issuer, is exempt from federal income tax.

         Risk Factors Regarding Investments in Texas Municipal Securities.
Because the Fund invests primarily in obligations issued by Texas entities, the
Fund's performance is partially dependent upon economic conditions within the
State of Texas generally and upon the economic condition of issuing governments
and their instrumentalities in particular. In the late 1980's, weakness in the
oil and gas related and agricultural sectors of the Texas economy adversely
affected consumer spending, financial institutions, utility demand, and real
estate values within the state. Consequently, the state and many of its local
governments had to increase sales, utilities, and ad valorem tax rates in order
to maintain revenue yields. In the past two


                                       32
<PAGE>   278
years, however, in contrast to the national economy, business activity in Texas
has strengthened, with employment growth occurring in most sectors. In addition,
Texas' major financial institutions have been recapitalized and bank failures
have generally ceased.

ARIZONA MUNICIPAL SECURITIES

         As used in the Prospectus and this Statement of Additional Information,
the term "Arizona Municipal Securities" refers to debt securities which are
issued by or on behalf of Arizona or its respective authorities, agencies,
instrumentalities and political subdivisions and which produce interest which,
in the opinion of counsel for the issuer, is exempt from both federal income tax
and Arizona personal income tax .

         Risk Factors Regarding Investments in Arizona Municipal Securities.
Arizona's outlook remains uncertain as long as the state does not adopt a plan
regarding long term matching of revenues and expenditures, especially for
education, health care and corrections. Arizona's growth continues to out pace
national averages, for example: (i) the state's 35% population growth during the
1980's was the third fastest rate in the nation, next to Alaska and Nevada; (ii)
Arizona's current population growth is over 2% per year, about twice the
national average; and (iii) the state's unemployment rate for the month of June,
1997 was 4.3%.

         Nonetheless, growth has been expensive for Arizona. During the
high-growth 1980's, combined per capita state and local expenditures climbed to
about 105% of the U.S. average from about 95%, according to data from the
Advisory Commission on Intergovernmental Relations. Between fiscal 1985 and
1990, the state managed five successive years of shortfalls with internal
borrowing, tax accelerations, one-time adjustments, and budget cuts. Since 1991,
the state's budget has been balanced. Although the Arizona State debt limit is
$350,000, and, by its Constitution, Arizona is a "pay as you go" State, the
State finances many capital improvements through revenue bonds, special tax
bonds or lease purchase arrangements, which are not treated as "debts", but
which greatly reduce the pressure on the State's annual budget. For example, the
Arizona Department of Transportation issues bonds supported by excise taxes on
fuel for propulsion of motor vehicles, the State's universities and community
colleges are funded in part through revenue bonds payable solely from tuitions
and student fees, and the State itself, from time to time, finances facilities
through annually renewable lease-purchase agreements. The various political
subdivisions of the state have differing debt limits, and their debts are not
aggregated into the State's debt limit.

         In addition, local conditions may materially effect any given issue or
issuer. Such conditions include, without limitation, (1) acts of God (such as
flooding or droughts), (2) mismanagement or bankruptcy of large tax payers or
users of an issuer's services or conduit borrowers who may be the true obligors
of a tax exempt issue, or who may bear a disproportionate share of the taxes,
special assessments or revenues supporting securities issued by an issuer, (3)
environmental enforcement actions instituted by the State or federal government,
(4) mismanagement of the issuer's affairs, (5) damage claims which exceed
insurance coverage or self-insurance reserves (neither the State of Arizona nor
its political subdivisions enjoy sovereign immunity from damage claims), or (6)
issuer bankruptcy.

         In addition, Arizona's continued population growth depends to some
extent on its ability to manage its water resources, as the State is
predominantly arid. Specifically, the great bulk of Arizona's population, and
the area wherein most future growth is expected to occur, is located in three
central Arizona counties, i.e. Maricopa (including the greater Phoenix
metropolitan area), Pima (including the Tucson metropolitan area), and Pinal
Counties.

         To a great extent continued growth in these counties will depend on
continued importation of water from the Colorado River. This is accomplished
through the Central Arizona Project, a federal water reclamation project, a
major portion (2 to 2.5 billion dollars) of which must be repaid through water
sales to, and taxes levied on, the water users in such counties. The actual
amount to be repaid is now the subject of litigation, which can be expected to
continue for several years. Construction of the Central Arizona Project was
declared to be substantially complete in October of 1993.

         Arizona's share of Colorado River water, although adjudicated by the
U.S. Supreme Court, is, to some extent, sought by the States of California and
Nevada who have expressed interest in gaining access to that portion of
Arizona's share not being put to beneficial use within the State. Arizona demand
for Central Arizona Project water is currently in the range of 35 to 40% of
Project capacity. The long range success of either California or Nevada's
position cannot be determined at this time.

         There is litigation pending in Arizona which could have material
effects on the value of Arizona school district bonds. Plaintiffs allege a
failure on behalf of the State to ensure that school facilities in districts
with lower assessed valuations are properly capitalized, in line with uniformly
applied objective standards. The Arizona Supreme Court ruled that Arizona's
statutory financing scheme for public education is not in compliance with the
Arizona Constitution.


                                       33
<PAGE>   279
         In 1996, the Arizona Legislature adopted legislation appropriating
additional state funding for school districts. It is unclear whether, when or in
what form the Arizona Legislature may further respond to the Court's direction
in Roosevelt to enact appropriate school budget and finance laws, nor can any
assurance be given that the Supreme Court will approve any such legislative
response or that the Supreme Court will not take further action in this matter,
either before or after any legislative response. The effect of any such
legislative or judicial action cannot be determined at this time, but such
action may have future material effects on the financial operations of Arizona
School Districts.

         In the Creighton Elementary School District case, taxpayers within
Creighton Elementary School District No. 14 of Maricopa County, Arizona (the
"Creighton District"), brought suit in the Superior Court of Maricopa County
against the Creighton District on the basis that the outstanding principal
amount of bonds previously issued by the Creighton District, together with
premium received in connection with the issuance of such bonds, should be
treated as debt for constitutional and statutory debt limit purposes. The
plaintiffs sought to enjoin the issuance of additional bonds, arguing that
accumulated initial issue premium should be treated as debt for constitutional
debt limit purposes. This premium, associated with the issuance of prior
Creighton District Bonds, if counted as debt, would, plaintiffs contended, cause
the bonds sought to be issued to exceed the Creighton District's debt limit. On
April 18, 1996, the Court entered a judgment in favor of the taxpayers,
enjoining the issuance of additional Creighton District Bonds. In a subsequent
minute entry, the court stated that the premium to be treated as debt is
determined on the amount the underwriter paid to the Creighton District for the
bonds in question and not on the price for which the underwriter resold such
bonds. In addition, the court has also subsequently stated that the premium
treated as debt attributable to each maturity is retired upon the payment of the
principal amount of the applicable maturity. It is not clear if, pursuant to the
judgment against the Creighton District, all or part of any premium received by
the Creighton District is subject to constitutional and statutory requirements
other than debt limits, such as the requirement for voter authorization. The
judgment was not appealed by the Creighton District. Many school districts in
Arizona have outstanding obligations (i.e. obligations, wherein large initial
issue premiums were received) similar to that of the Creighton District.

         Notwithstanding such litigation, issuer's counsel, representing school
districts has or will issue an unqualified opinion with respect to the validity,
enforceability and tax-exempt status of School District Bonds before such Bonds
are acquired by the fund. The standard of certainty applicable to such opinion
is that it would be unreasonable for a court to hold to the contrary with
respect to matters addressed therein.

         The Arizona Legislature has passed legislation with respect to the
treatment of premium and debt. Under this legislation, the outstanding
indebtedness of a jurisdiction is equal to the total principal amount of all
bonds outstanding at the time of calculation. Additionally, premium is not
counted as debt, but the amount of premium permitted for bonds issued after the
passage of the legislation is limited to the greater of 2% of the par value of
the bond issue or $100,000. This legislation further validated all then
outstanding general obligation and general obligation refunding Bonds which
might have been subject to challenge after the Creighton ruling.

         It is not known whether the Act will be challenged in court or whether,
if challenged, all or any portion of the act would be upheld.

LOUISIANA MUNICIPAL SECURITIES

         As used in the Prospectus and this Statement of Additional Information,
the term "Louisiana Municipal Securities" refers to debt securities which are
issued by or on behalf of Louisiana or its respective authorities, agencies,
instrumentalities and political subdivisions and which produce interest which,
in the opinion of counsel for the issuer, is exempt from both federal income tax
and Louisiana personal income tax.

         Risk Factors Regarding Investments in Louisiana Municipal Securities.
Louisiana's general obligation bonds are currently rated A3 by Moody's and A
minus by S&P. Louisiana's ratings reflect an ongoing recovery process from the
severe financial problems which developed after oil prices declined in the
mid-to-late 1980's. Also, both rating agencies have commended the State for
enacting constitutional reforms in the Fall of 1993 that curb borrowing and
require that non-recurring revenues be applied to debt reduction. However,
Louisiana is still somewhat weak in terms of its credit fundamentals. While
ratings of individual cities, parishes, agencies and special districts vary,
most Louisiana issuers have been affected to some degree by Louisiana's economy.

         Through the oil boom of the late 1970s and early 1980s, Louisiana's
labor force and employment grew steadily, as did its financial position.
However, when the oil industry weakened, economic growth slowed and operating
deficits occurred, Louisiana's undesignated General Fund deficit reached $512
million in fiscal 1988 (ended June 30) and the fund balance was a negative $377
million.

         Louisiana implemented a plan to eliminate its deficits and $979 million
of revenue bonds were sold in 1988, secured by (i) the revenues from a 1%
statewide sales and use tax, and (ii) all funds, accounting and investment
earnings with respect to said revenue bonds. All of the bonds issued have now
been retired.

         During the period from fiscal year 1991-92 through fiscal year 1995-96,
the state experienced operating budget surpluses in four of the five fiscal
years. The table below sets forth in summary fashion the condition of the
State's General Fund from fiscal years 1991-92 through 1994-95.

(1)      Approximately $106 million in beginning undesignated fund balance was
         utilized to defease future debt service attributable to fiscal year
         1995-96 as described below.

(2)      The $146 million in ending underestimated fund balance was utilized to
         defease future debt service attributable to fiscal year 1996-97.

         Upon the actual completion of the fiscal year 1991-1992, it was learned
that the State's General Fund actually ended fiscal year 1991-92 with an
undesignated fund balance deficit of $83 million. This shortfall was eliminated
within the 1992-93 budgetary fiscal cycle by utilizing a set aside against the
total balance available for appropriations, resulting from the official
projections of the Revenue Estimating Conference, prior to any budget adjustment
approval submitted to the Joint Legislative Committee on the Budget.

         The State ended the fiscal year 1992-93 with a positive undesignated
fund balance in its General Fund of $101 million. During 1994, $30.6 million of
the surplus funds were utilized to cover known shortfalls in current year
program operations. As noted in the table above, the State ended the fiscal year
1993-94 with an operating surplus of $129 million dollars. This amount together
with the prior year fund balance of $101 million and reserve changes left an all
unreserved-undesignated balance in the General Fund of $212.9 million.

         The State began fiscal year 1994-95 with a General Fund balance of $594
million. At the time the projections of the Revenue Estimating Conference for
fiscal year 1993-94 were published, the undesignated fund balance was reflected
at $212 million. Subsequent to publication, it was determinate that $106 million
of the $212 million was, in fact, designated for other mandated purposes and was
not available for general operating purposes. The remaining $106 million was
subsequently utilized prior to June 30, 1995, to structure a current portfolio
that was utilized to defease a portion of the State's fiscal year 1994-95
general obligation debt service requirement, which freed an equivalent amount of
projected general fund revenues for fiscal year 1994-95 to be utilized to cover
normal operating costs.

         The State's General Fund had an operating loss (on a generally accepted
accounting principles basis) of $181 million in fiscal year 1994-95 (on a
budgetary basis, this balance would be reduced by those fund balances utilized
to structure the aforementioned portfolio). As a result of operations and
inventory valuation changes, the State General Fund balance, as of June 30,
1996, declined to $427 million, of which $145 million was undesignated or
reserved for a future purpose.

         The current general fund expenditure authorization necessary to
continue all existing programs through fiscal year 1996-97 is approximately
$5,271.9 million, inclusive of currently known supplemental appropriation needs.
The revised estimate of revenues for fiscal year 1996-97 is $5,487.5 million. In
addition, general fund revenues of $12.6 million were carried forward from
fiscal year 1995-96, making a total of $5,500.1 million available for general
fund expenditures in fiscal year 1996-97. The $228.2 million balance between
available revenues and projected expenditures is available for any lawful
purpose. The State's cash flow position for fiscal year 1996-97 has improved in
comparison to the State's cash flow position


                                       35
<PAGE>   281
for fiscal year 1995-96. Month end balances for fiscal year 1996-97 show less
pronounced fluctuations than in the previous year.

         The State's budget projections may also be impacted by certain matters
relating to the Medicaid program. On April 26, 1996, Congress adopted a budget
bill which included a two year funding base specifically for the State Medicaid
program, covering October 1, 1995 though June 30, 1997. That budget bill capped
federal Medicaid funds allocated to the State at a certain amount until the
State could increase its matching contribution to federally required levels.

         The State implemented a series of Medicaid program reductions in Fiscal
Year 1996-97 to ensure the Medicaid program would not exceed the total of the
State-required match and federal share. Proposed changes in the design of the
Medicaid program at the federal level may further cause the State to alter its
Medicaid program in order to continue to provide necessary medical services to
the indigent population of the State in future years.

         Total Medicaid spending has been reduced by 30% from its Fiscal Year
1993-94 level of $4.6 billion. The appropriation for the Medicaid program
(including administration) at the beginning of Fiscal Year 1996-97 was $3.23
billion. This appropriation was increased to $3.31 billion in order to provide
for a State-funded medically needy program and for certain non-recurring costs.

         Although the Congressional Fiscal Year 1995-96 budget bill indicated an
intent to allow the State a third year (Fiscal Year 1997-98) to reach the
federally required matching levels, the chances of that reauthorization are
uncertain, and therefore, the State's Fiscal year 1997-98 budget does not
reflect continuation of that funding. The Medicaid funding picture for Fiscal
Year 1997-98 was clarified with the Administration's recent proposal that the
Medicaid program be supported at $3.19 billion in total funding with $966
million in State matching funds. This level of State match is nearly $200
million higher than that called for under the special financing arrangement
passed by Congress in 1996 because Congressional reauthorization of this
arrangement for Fiscal Year 1997-98 is given little chance of passage. The total
Medicaid funding level of $3.19 billion is approximately $100 million lower than
the Fiscal Year 1996-97 budget. DHH will propose a plan to the Legislature to
align program spending with available revenues.

         In 1996, the Legislature passed a "local option" bill which permitted
voters in all parishes to decide during the 1996 November general election
whether to allow specified forms of gaming to continue. Thirty-three parishes
voted against continuation of video draw poke device operations and 31 parishes
voted to allow video draw poker device operations to continue. In parishes where
video draw poker was voted out, no new video draw poker licenses may be issued,
and those already operating may renew their one-year video draw poker licenses
for only two more times. Initial estimates for the loss of revenues associated
with almost half the State's parishes voting against continuation of the video
draw poker devices is estimated at $70 million for fiscal year 1997-2000.

         Economically, Louisiana will continue to be affected by world energy
markets. Approximately 15% of the nation's crude oil and approximately 28% of
its natural gas are produced in Louisiana. In the past the State has estimated
that up to 25% of its economy is directly or indirectly related to energy. This
is despite the fact that only 5.5% of employment is in oil and gas extraction,
chemicals and allied products and petroleum refining. Oil and oil related jobs
also tend to be at relatively high wages, magnifying their economic effect.
Similarly, although severance taxes and royalties accounted for almost 4.3% of
operating revenues for fiscal year 1993-1994, compared with almost 25% ten years
ago, energy related activity affects individual and corporate taxes, which
together with sales taxes account for 21.3% of general revenues. Unemployment
declined in Louisiana from 12% in 1987 to 6.2% in 1990. This was due in part to
increased employment but also to out-migration of population and a decline in
labor force. Louisiana's jobless rate has since risen to 6.9% as of December 31,
1995. The comparable national unemployment rate was 5.6%. In addition to oil and
gas, major contributors to Louisiana's economy include chemical production,
shipping, agriculture and tourism.

         Louisiana's debt burden is well above that of other states, while
wealth and income indicators are below the national average. In 1995,
Louisiana's per capital personal income was $18,981 as compared with the
national average of $23,208. According to Moody's, Louisiana's State-level tax
supported debt is the sixth highest as a percentage of personal income and
eighth highest on a per-capita basis.

         Municipal obligations are subject to the provisions of bankruptcy,
insolvency and other laws affecting the rights and remedies of creditors, such
as the Federal Bankruptcy Code, and laws, if any, which may be enacted by
Congress or State legislatures extending the time for payment of principal or
interest, or both, or imposing other constraints upon enforcement of such
obligations or upon municipalities to levy taxes. There is also the possibility
that as a result of litigation or other conditions the power or ability of any
one or more issuers to pay when due principal or interest on its or their
municipal obligations may be materially affected.

INVESTMENT RESTRICTIONS

         The following investment restrictions are FUNDAMENTAL and may be
changed with respect to a particular Fund only by a vote of a majority of the
outstanding Shares of that Fund. See "ADDITIONAL INFORMATION-- Miscellaneous" in
this Statement of Additional Information.

         Each of the Equity Funds may not:

         1. Purchase securities of any issuer (except securities issued or
guaranteed by the United States, its agencies or instrumentalities, and, if
consistent with a Fund's investment objective and policies, repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of a Fund would be invested in the securities of such issuer or a Fund
would own more than 10% of the outstanding voting securities of such issuer.
This restriction applies to 75% of a Fund's assets. With respect to The One
Group Equity Index Fund, no more than 10% of the Funds assets may be invested in

conducting their principal business activities in the same industry, provided
that this limitation does not apply to investments in the obligations issued or
guaranteed by the U.S. government or its agencies and instrumentalities and
repurchase agreements involving such securities. For purposes of this limitation
(i) utilities will be divided according to their services (for example, gas, gas
transmission, electric and telephone will each be considered a separate

the industries of their parents if their activities are primarily related to
financing the activities of their parents.

         3. Make loans, except that a Fund may (i) purchase or hold debt

would own more than 10% of the outstanding voting securities of such issuer,
provided, however, that a Fund may invest up to 25% of its total assets without
regard to this restriction as permitted by applicable law and also provided that
with respect to the Ohio Municipal Money Market Fund, as to 50% of such Fund's
assets, the Fund may invest up to 25% of its assets in the securities of a
single issuer. With respect to remaining 50% of its total assets, the Ohio

a result more than 5% of the total assets of the Fund would be invested in the
securities of such issuer. For purposes of these limitations, a security is
considered to be issued by the government entity whose assets and revenues
guarantee or back the security. With respect to private activity bonds or
industrial development bonds backed only by the assets and revenues of a
nongovernmental user, such user would be considered the issuer.

         2. Purchase any securities that would cause more than 25% of the total

         The Arizona Municipal Bond Fund, the West Virginia Municipal Bond, the
Louisiana Municipal Bond Fund, The Ohio Municipal Bond Fund and the Kentucky
Bond Fund may not:

         1. Purchase securities of any issuer (except securities issued or

         1. Make loans, except that a Fund may (i) purchase or hold debt
instruments in accordance with its investment objective and policies; (ii) enter
into repurchase agreements; and (iii) engage in securities lending as described
in this Prospectus and in the Statement of Additional Information.

         None of the Funds may:

         1. Purchase securities on margin, sell securities short, or participate
in a joint or joint and several basis in any securities trading account, except,
in the case of the Municipal Bond Funds, for use of short-term credit necessary
for clearance of purchases of portfolio securities.

         2. Underwrite the securities of other issuers except to the extent that
a Fund may be deemed to be an underwriter under certain securities laws in the
disposition of "restricted securities."

         3. Purchase or sell commodities or commodity contracts (including
futures contracts), except that for bona fide hedging and other permissible
purposes: (i) the Equity, Bond and International Equity Index Funds may purchase
or sell financial futures contracts and (except for the Treasury & Agency Fund)
may purchase call or put options on financial futures contracts, and (ii) the
International Equity Index Fund may purchase or sell foreign currency futures
contracts and foreign currency forward contacts, and may purchase put or call
options on foreign currency futures contracts and on foreign currencies on
appropriate U.S. exchanges, and may purchase or sell foreign currency on a spot
basis.

         4. Except for the Treasury & Agency Fund, purchase participation or
other direct interests in oil, gas or mineral exploration or development
programs (although investments by all Funds other than the U.S. Treasury
Securities Money Market, Treasury Money Market, Treasury Only Money Market and
Government Money Market Fund in marketable securities of companies engaged in
such activities are not hereby precluded).

         5. Invest in any issuer for purposes of exercising control or
management.

         6. Purchase securities of other investment companies except as
permitted by the 1940 Act and rules, regulations and applicable exemptive relief
thereunder.

         7. Purchase or sell real estate (however, each Fund except the Money
Market Funds may, to the extent appropriate to its investment objective,
purchase securities secured by real estate or interests therein or securities
issued by companies investing in real estate or interests therein).

         8. Borrow money or issue senior securities, except that each Fund may
borrow from banks or enter into reverse repurchase agreements for temporary
purposes in amounts up to 10% of the value of its total assets at the time of
such borrowing; or mortgage, pledge, or hypothecate any assets, except in
connection with any such borrowing and in amounts not in excess of the lesser of
the dollar amounts borrowed or 10% of the value of the Fund's total assets at
the time of its borrowing. A Fund will not purchase securities while its
borrowings (including reverse repurchase agreements) in excess of 5% of its
total assets are outstanding.

         In addition, the U.S. Treasury Securities Money Market, the Prime Money
Market and the Institutional Money Market Funds may not:

         1. Buy common stocks or voting securities.

         In addition, the U.S. Treasury Securities Money Market Fund, the Prime
Money Market Fund and the Government Money Market Fund may not

         1. Buy state, municipal, or private activity bonds.

         The following investment restrictions are NON-FUNDAMENTAL except as
noted otherwise and therefore can be changed by the Board of Trustees without
prior shareholder approval.

         No Fund may:

         1. Invest in illiquid securities in an amount exceeding, in the
aggregate 15% of the Fund's net assets (10% of net assets for a Fund that is a
Money Market Fund). An illiquid security is a security which cannot be disposed
of promptly (within seven days) and in the usual course of business without a
loss, and includes repurchase agreements maturing in excess


                                       40
<PAGE>   286
of seven days, time deposits with a withdrawal penalty, non-negotiable
instruments and instruments for which no market exists. (This restriction is
fundamental with respect to the Ohio Municipal Money Market Fund.)

         2. Acquire the securities of registered open-end investment companies
or registered unit investment trusts in reliance on Section 12(d)(1)(F) or
12(d)(1)(G) of the 1940 Act, other than the Investor Growth Fund, the Investor
Growth & Income Fund, the Investor Conservative Growth Fund, the Investor
Balanced Fund, the Investor Aggressive Growth Fund, and the Investor Fixed
Income Fund.

         The foregoing percentages apply at the time of purchase of a security.

   
         Additionally, although not a matter controlled by their fundamental
investment restrictions, so long as their shares are registered under the
securities laws of the State of Texas, the Prime Money Market Fund and the Ohio
Municipal Money Market Fund will: (i) limit their investments in other
investment companies to no more than 10% of each Funds total asset; (ii) invest
only in other investment companies with substantially similar investment
objectives; and (iii) invest only in other investment companies with charges and
fees substantially similar to those set forth in paragraph (3) and (4) of
Section 123.3 of the Texas State Statute, not to exceed .25% in 12b-1 and no
other commission or other remuneration is paid or given directly or indirectly
for soliciting any security holder in Texas.

         In addition, the Intermediate Tax-Free Bond Fund will not invest more
than 25% of its assets in municipal securities that are related in such a way
that a political, economic or business development affecting one security will
also affect other municipal securities.
    

PORTFOLIO TURNOVER

         The portfolio turnover rate for each Fund is calculated by dividing the
lesser of purchases or sales of portfolio securities for the year by the monthly
average value of the portfolio securities. The calculation excludes all
securities whose maturities at the time of acquisition were one year or less.
Thus, for regulatory purposes, the portfolio turnovers with respect to the Money
Market Funds were zero for the period from the commencement of their respective
operations to June 30, 1997 and are expected to remain zero, and the portfolio
turnover rate with respect to the Institutional Money Market Funds is expected
to be zero.

         The portfolio turnover rates of the Funds for the fiscal years ended
June 30, 1997 and 1996 were as follows:

         The high portfolio turnover rates for the fiscal year ended June 30,
1997 for the Growth Opportunities Fund and the Value Growth Fund resulted from
various factors, including some or all of the following: investment strategies,
unusually high market volatility and significant growth of the Funds. Portfolio
turnover may vary greatly from year to year as well as within a particular year,
and may also be affected by cash requirements for redemptions of Shares and by
requirements which enable the Trust to receive certain favorable tax treatments.
Portfolio turnover will not be a limiting factor in making portfolio decisions.

ADDITIONAL TAX INFORMATION CONCERNING ALL FUNDS

         Each Fund is treated as a separate entity for federal income tax
purposes and is not combined with The One Group's other funds. It is the policy
of each Fund of the Trust to meet the requirements necessary to qualify as a
"regulated investment company" under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code"). By following such policy, each Fund expects to
eliminate or reduce to a nominal amount the federal income taxes to which it may
be subject.

         In order to qualify as a regulated investment company, each Fund of the
Trust must, among other things, (1) derive at least 90% of its gross income from
dividends, interest, payments with respect to securities loans, and gains from
the sale or other disposition of stock or securities, foreign currencies or
other income (including gains from options, futures or forward contracts)
derived with respect to its business of investing in stock, securities or
currencies, (2) derive less than 30% of its gross income from the sale or other
disposition of stock, securities, options, futures, forward contracts, and
certain foreign currencies (or certain options, futures, or forward contracts on
foreign currencies) held for less than three months, and (3) diversify its
holdings so that at the end of each quarter of its taxable year (i) at least 50%
of the market value of the Fund's assets is represented by cash or cash items,
United States government securities, securities of other regulated investment
companies, and other securities limited, in respect of any one issuer, to an
amount not greater than 5% of the value of the Fund's assets and 10% of the
outstanding voting securities of such issuer, and (ii) not more than 25% of the
value of its assets is invested in the securities of any one issuer (other than
United States government securities or the securities of other regulated
investment companies) or of two or more issuers that the Fund controls and that
are engaged in the same, similar, or related trades or businesses. These
requirements may restrict the degree to which the Fund may engage in short-term
trading and limit the range of the Fund's investments. If a Fund of the Trust
qualifies as a regulated investment company, it will not be subject to federal
income tax on the part of its income distributed to Shareholders, provided the
Fund distributes during its taxable year at least (a) 90% of its taxable net
investment income (very generally, dividends, interest, certain other income,
and the excess, if any, of net short-term capital gain over net long-term loss),
and (b) 90% of the excess of (i) its tax-exempt interest income (if any) less
(ii) certain deductions attributable to that income. Each Fund of the Trust
intends to make sufficient distributions to Shareholders to qualify for this
special tax treatment.

         If a Fund failed to qualify as a regulated investment company receiving
special tax treatment in any taxable year, the Fund would be subject to tax on
its taxable income at corporate rates, and all distributions from earnings and
profits, including any distributions of net tax-exempt income and net long-term
capital gains, would be taxable to Shareholders as ordinary income. In addition,
the Fund could be required to recognize unrealized gains, pay substantial taxes
and interest and make substantial distributions before requalifying as a
regulated investment company and being accorded special tax treatment.

         Regulated investment companies that do not distribute in each calendar
year (regardless of whether they otherwise have a non-calendar taxable year) an
amount equal to 98% of their "ordinary income" (as defined) for the calendar
year, plus 98% of their capital gain net income (as defined) for the one-year
period ending on October 31 of such calendar year, plus any undistributed
amounts from the previous year are subject to a non-deductible excise tax equal
to 4% of the undistributed amounts. For purposes of the excise tax, a Fund is
treated as having distributed any amount on which it is subject to income tax
for any taxable year ending in such calendar year. Each Fund of the Trust
intends to make sufficient distributions to avoid liability for the excise tax.


                                       42
<PAGE>   288
         Shareholders of the Funds will generally be subject to federal income
tax on distributions received from the Funds. Dividends that are attributable to
a Fund's net investment income will be taxed to shareholders as ordinary income.
Distributions of net capital gain that are designated by a Fund as capital gain
dividends will generally be taxable to a Shareholder receiving such
distributions as long-term capital gain regardless of how long the Shareholder
has held its shares. Distributions in excess of a Fund's current and accumulated
"earnings and profits" will be treated by a Shareholder receiving such
distributions as a return of capital to the extent of such Shareholder's basis
in its Shares in the Fund, and thereafter as capital gain. A return of capital
is not taxable, but reduces a Shareholder's basis in its shares. Shareholders
not subject to tax on their income generally will not be required to pay tax on
amounts distributed to them. The sale, exchange or redemption of Fund shares by
a Shareholder may give rise to a taxable gain or loss to that Shareholder. In
general, any gain or loss realized upon a taxable disposition of shares will be
treated as long-term capital gain or loss if the Shareholder has held the shares
for more than 12 months, and otherwise as short-term capital gain or loss.
However, if a Shareholder sells shares at a loss within six months of purchase,
any loss will be disallowed for Federal income tax purposes to the extent of any
exempt-interest dividends received on such shares. A Fund may designate a
portion of its distributions of net capital gain as deriving from capital assets
held for more than one year but not more than 18 months ("mid-term gain"). The
balance of such distributions, deriving from capital assets held for more than
18 months, may be included in a Shareholder's computation of its adjusted net
capital gain. In addition, a Shareholder's gain upon a taxable disposition of
shares held for more than one year but not more than 18 months will qualify as
mid-term gain, and gain upon a taxable disposition of shares held for more than
18 months may be included in the Shareholders' computation of its adjusted net
capital gain. It is expected that pursuant to forthcoming regulations, the Fund
will provide shareholders with information allowing them to calculate their
mid-term gains and adjusted net capital gains.

         In addition, any loss (not already disallowed as provided in the
preceding sentence) realized upon a taxable disposition of shares held for six
months or less will be treated as long-term to the extent of any long-term
capital gain distributions received by the Shareholder with respect to the
shares. All or a portion of any loss realized upon a taxable disposition of Fund
shares will be disallowed if other Fund shares are purchased within 30 days
before or after the disposition. In such a case, the basis of the newly
purchased shares will be adjusted to reflect the disallowed loss.

         Certain investment and hedging activities of the Funds, including
transactions in options, futures contracts, hedging transactions, forward
contracts, straddles, swaps, short sales, foreign currencies, and foreign
securities will be subject to special tax rules. In a given case, these rules
may accelerate income to the Fund, defer losses to the Fund, cause adjustments
in the holding periods of the Fund's securities, convert short-term capital
losses into long-term capital losses, or otherwise affect the character of the
Fund's income. These rules could therefore affect the amount, timing and
character of distributions to Shareholders and cause differences between a
Fund's book income and taxable income. Income earned as a result of these
transactions would, in general, not be eligible for the dividends-received
deduction or for treatment as exempt-interest dividends when distributed to
Shareholders. The Fund will endeavor to make any available elections pertaining
to such transactions in a manner believed to be in the best interest of the
Fund.

         Certain securities purchased by the Funds (such as STRIPS, CUBES, TRS,
TIGRS, and CATS), as defined in "Details About the Funds' Investment Practices
and Policies" in the Funds' Prospectuses, are sold at original issue discount
and thus do not make periodic cash interest payments. Similarly, zero-coupon
bonds do not make periodic interest payments. A Fund will be required to include
as part of its current income for tax purposes the imputed interest on such
obligations even though the Fund has not received any interest payments on such
obligations during that period. Because each Fund distributes substantially all
of its net investment income to its Shareholders (including such imputed
interest), the Fund may have to sell portfolio securities in order to generate
the cash necessary for the required distributions. Such sales may occur at a
time when Banc One Advisors would not otherwise have chosen to sell such
securities and may result in a taxable gain or loss.

         A Fund will be required in certain cases to withhold and remit to the
United States Treasury 31% of taxable dividends or of gross proceeds from
redemptions paid to any individual Shareholder who has provided to the Fund
either an incorrect tax identification number or no number at all, or who is
subject to withholding by the Internal Revenue Service for failure properly to
report payments of interest or dividends. This withholding, known as backup
withholding, is not an additional tax, and any amounts withheld may be credited
against the Shareholder's ultimate U.S. tax liability.



















         The foregoing is only a summary of some of the important federal tax
considerations generally affecting purchasers of Shares of a Fund of the Trust.
Further tax information regarding the Tax-Advantaged Funds and the International
Equity Index Fund is included in following sections of this Statement of
Additional Information. No attempt is made to present herein a complete
explanation of the federal income tax treatment of each Fund or its
Shareholders, and this discussion is not intended as a substitute for careful
tax planning. Accordingly, prospective purchasers of Shares of a Fund are urged
to consult their tax advisors with specific reference to their own tax
situation, including the potential application of state, local and (if
applicable) foreign taxes.

         The foregoing discussion and the discussion below regarding the
Tax-Advantaged Funds and the International Equity Index Fund are based on tax
laws and regulations which are in effect on the date of this Statement of
Additional Information;


                                       43
<PAGE>   289
such laws and regulations may be changed by legislative, judicial or
administrative action, and such changes may be retroactive.

ADDITIONAL TAX INFORMATION CONCERNING THE TAX-ADVANTAGED FUNDS

         The Code permits a regulated investment company which has invested, at
the close of each quarter of its taxable year, at least 50% of its total assets
in tax-free Municipal Securities and other securities the interest on which is
exempt from the regular federal income tax to pay exempt-interest dividends to
its Shareholders.

         The policy of each Tax-Advantaged Fund is to distribute each year as
exempt-interest dividends substantially all the Fund's net exempt interest
income. An exempt-interest dividend is any dividend or part thereof (other than
a capital gain dividend) paid by a Tax-Advantaged Fund and designated as an
exempt-interest dividend in a written notice mailed to Shareholders after the
close of the Fund's taxable year, which does not exceed, in the aggregate, the
net interest income from Municipal Securities and other securities the interest
on which is exempt from the regular federal income tax received by the Fund
during the taxable year. The percentage of the total dividends paid for any
taxable year which qualifies as federal exempt-interest dividends will be the
same for all Shareholders receiving dividends from a Tax-Advantaged Fund during
such year, regardless of the period for which the Shares were held.

         Exempt-interest dividends may generally be treated by a Tax-Advantaged
Fund's Shareholders as items of interest excludable from their gross income
under Section 103(a) of the Code. However, each Shareholder of a Tax-Free Fund
is advised to consult his or her tax advisor with respect to whether such
Shareholder may be treated as a "substantial user" or a "related person" to such
user under Section 147(a) with respect to facilities financed through any of the
tax-exempt obligations held by the Fund. "Substantial user" is defined under
U.S. Treasury Regulations to include a non-exempt person who regularly uses a
part of such facilities in his trade or business and (a)(i) whose gross revenues
derived with respect to the facilities financed by the issuance of bonds are
more than 5% of the total revenues derived by all users of such facilities or
(ii) who occupies more than 5% of the usable area of the facility or (b) for
whom such facilities or a part thereof were specifically constructed,
reconstructed or acquired.

         "Related persons" includes certain related natural persons, affiliated
corporations, partners and partnerships.

         Dividends attributable to interest on certain private activity bonds
issued after August 7, 1986 must be taken into account in determining
alternative minimum taxable income for purposes of determining liability (if
any) for the alternative minimum tax applicable to individuals and the
alternative minimum tax applicable to corporations. In the case of corporations,
all tax-exempt interest dividends will be taken into account in determining
adjusted current earnings for the purpose of computing the alternative minimum
tax imposed on corporations (as defined for federal income tax purposes).

         Current Federal law limits the types and volume of bonds qualifying for
Federal income tax exemption of interest, which may have an effect on the
ability of the Funds to purchase sufficient amounts of tax exempt securities to
satisfy the Code's requirements for the payment of "exempt-interest" dividends.

         Each Tax-Advantaged Fund may at times purchase Municipal Securities (or
other securities the interest on which is exempt from the regular federal income
tax) at a discount from the price at which they were originally issued. For
federal income tax purposes, some or all of the market discount will be included
in the Fund's ordinary income and will be taxable to shareholders as such when
it is distributed to them.

         Each Tax-Advantaged Fund may acquire rights regarding specified
portfolio securities under puts. See "Puts." The policy of each Tax-Free Fund is
to limit its acquisition of puts to those under which the Fund will be treated
for federal income tax purposes as the owner of the Municipal Securities
acquired subject to the put and the interest on the Municipal Securities will be
tax-exempt to the Fund. Although the Internal Revenue Service has issued a
published ruling that provides some guidance regarding the tax consequences of
the purchase of puts, there is currently no guidance available from the Internal
Revenue Service that definitively establishes the tax consequences of many of
the types of puts that the Funds could acquire under the 1940 Act. Therefore,
although a Tax-Advantaged Fund will only acquire a put after concluding that it
will have the tax consequences described above, the Internal Revenue Service
could reach a different conclusion from that of the Fund.

         Following is a brief discussion of treatment of exempt-interest
dividends by certain states.

         ARIZONA TAXES. Shareholders of the Arizona Municipal Bond Fund will not
be subject to Arizona income tax on exempt-interest dividends received from the
Fund to the extent that such dividends are attributable to interest on
tax-exempt obligations of the state of Arizona and its political subdivisions
("Local Obligations"). Interest from Local Obligations however, may be
includable in Federal gross income.

<PAGE>   290
         KENTUCKY TAXES. Fund shares are currently exempt from the Kentucky tax
on intangible property. The Kentucky Supreme Court recently held that corporate
shares are not subject to the Kentucky intangible property tax because of an
exemption for shares of certain corporations with in-state activities which the
Court held to violate the Commerce Clause of the U.S. Constitution. The Kentucky
Revenue Cabinet has announced that, in light of the ruling, it will not, as a
matter of policy, require that the Kentucky intangible property tax be paid on
any portion of the value of shares of any mutual fund. Previously the Cabinet
had required owners of shares of mutual funds to pay tax on the portion of their
share value representing underlying fund assets not exempt from the tax.

         The Cabinet could change this policy in the future. The Kentucky
General Assembly could re-enact the intangible tax on corporate shares and other
similar securities without the exemption found objectionable by the Court. There
is no assurance that the Fund shares will remain free from the Kentucky
intangible property tax.

         WEST VIRGINIA TAXES. Shareholders may reduce their West Virginia
adjusted gross income ("AGI") for that portion of the interest or dividends they
receive which represents interest or dividends of the Fund on obligations or
securities of any authority, commission or instrumentality of West Virginia that
is exempt from the West Virginia personal income tax by Federal or West Virginia
law. Shareholders may also reduce their West Virginia AGI for that portion of
interest or dividends received from the Fund derived from obligations of the
United States and from obligations or securities of some authorities,
commissions or instrumentalities of the United States.

         However, shareholders cannot reduce their West Virginia AGI for any
portion of interest or dividends received from the Fund derived from income on
obligations of any state, or political subdivision thereof, other than West
Virginia, regardless of any Federal law exemption, such as that accorded
"exempt-interest dividends;" and they must increase their West Virginia AGI by
the amount of such interest or dividend income. Also, a shareholder must
increase his West Virginia AGI by interest on indebtedness incurred (directly or
indirectly) to purchase or hold shares of the Fund to the extent such interest
was deductible in determining Federal AGI. The sale, exchange, or redemption of
Fund shares is subject to the West Virginia income tax to the extent the gain or
loss therefrom affects the determination of the shareholder's Federal AGI.

         The foregoing is only a summary of some of the important tax
considerations generally affecting purchasers of Shares of a Tax-Advantaged
Fund. Additional tax information concerning all Funds of the Trust is contained
in the immediately preceding section of this Statement of Additional
Information. No attempt is made to present a complete explanation of the federal
income tax treatment of each Tax-Advantaged Fund or its Shareholders, and this
discussion is not intended as a substitute for careful tax planning.
Accordingly, prospective purchasers of Shares of a Tax-Advantaged Fund are urged
to consult their tax advisors with specific reference to their own tax
situation, including the potential application of state, local and foreign
taxes.

ADDITIONAL TAX INFORMATION CONCERNING THE INTERNATIONAL EQUITY INDEX FUND

         Transactions of the International Equity Index Fund in foreign
currencies, foreign currency denominated debt securities and certain foreign
currency options, future contracts and forward contracts (and similar
instruments) may result in ordinary income or loss to the Fund for federal
income tax purposes which will be taxable to the Shareholders as such when it is
distributed to them.

         Gains from foreign currencies (including foreign currency options,
foreign currency futures and foreign currency forward contracts) will constitute
qualifying income for purposes of the 90% test only to the extent that they are
directly related to the trust's business of investing in stock or securities.

         Investment by the International Equity Index Fund in certain "passive
foreign investment companies" could subject the Fund to a U.S. federal income
tax or other charge on proceeds from the sale of its investment in such a
company or other distributions from such a company, which tax cannot be
eliminated by making distributions to International Equity Index Fund
Shareholders. If the International Equity Index Fund elects to treat a passive
foreign investment company as a "qualified electing fund," different rules would
apply, although the International Equity Index Fund does not expect to make such
an election. Rather, the Fund intends to avoid such tax or other charge by
making an election to mark gains (and to a limited extent, losses) from such
investments to market annually.

FOREIGN TAX CREDIT

         If more than 50% of the International Equity Index Fund's total assets
at year end consist of the debt and equity securities of foreign corporations,
the Fund may elect to permit its Shareholders who are U.S. citizens to claim a
foreign tax credit or deduction on their U.S. income tax returns for their pro
rata share of foreign taxes paid by the Fund. In that case, Shareholders will be
required to include in gross income their pro rata share of foreign taxes paid
by the Fund. Each Shareholder may then claim a foreign tax credit or a tax
deduction that would offset some or all of the increased tax liability.
Generally, a credit for foreign taxes is subject to the limitation that it may
not exceed the Shareholder's U.S. tax attributable


                                       45
<PAGE>   291
to his or her total foreign source taxable income. For this purpose, the source
of the income to the International Equity Index Fund flows through to the Fund's
Shareholders. In addition, no credit will be allowed for foreign taxes paid in
respect of any dividend on stock paid or accrued after September 4, 1997 unless
the stock was held (without protection from risk of loss) for at least 16 days
during the 30-day period beginning 15 days before the ex-dividend date. For
certain preferred stock the holding period is 46 days during a similar 90-day
period. This means that (i) Shareholders not satisfying this holding period
requirement may not claim foreign tax credits in respect of their shares, and
(ii) the Fund may not "flow through" tax credits to Shareholders in respect of
dividends on stock that the Fund has not held for the requisite period. If the
Fund makes this election with respect to foreign tax credits it will notify
Shareholders of their proportionate share of foreign taxes paid, the portion of
the distribution that represents foreign source income, and any amount of such
foreign taxes paid which are not creditable because the Fund did not meet the
holding period requirement. Gains to the International Equity Index Fund from
the sale of securities generally will be treated as derived from U.S. sources
and certain currency fluctuation gains, including fluctuation gains from foreign
currency denominated debt securities, receivables and payables, will be treated
as ordinary income derived from U.S. sources. With limited exceptions, the
foreign tax credit is allowed to offset only 90% of the alternative minimum tax
imposed on corporations and individuals. Because of these limitations,
Shareholders may be unable to claim a credit for the full amount of their
proportionate share of the foreign taxes paid by the International Equity Index
Fund.

         The foregoing is only a general description of the treatment of foreign
source income or foreign taxes under the United States federal income tax laws.
Because the availability of a credit or deduction depends on the particular
circumstances of each Shareholder, Shareholders are advised to consult their own
tax advisors.


                                    VALUATION

VALUATION OF THE MONEY MARKET AND INSTITUTIONAL MONEY MARKET FUNDS

         The Money Market and Institutional Money Market Funds have elected to
use the amortized cost method of valuation pursuant to Rule 2a-7 under the 1940
Act. This involves valuing an instrument at its cost initially and thereafter
assuming a constant amortization to maturity of any discounts or premium,
regardless of the impact of fluctuating interest rates on the market value of
the instrument. This method may result in periods during which value, as
determined by amortized cost, is higher or lower than the price each Fund would
receive if it sold the instrument. The value of securities in the Funds can be
expected to vary inversely with changes in prevailing interest rates.

         Pursuant to Rule 2a-7, the Money Market and Institutional Money Market
Funds will maintain a dollar-weighted average portfolio maturity appropriate to
their objective of maintaining a stable net asset value per Share, provided that
no Fund will purchase any security with a remaining maturity of more than 397
days (securities subject to repurchase agreements and certain variable or
floating rate instruments may bear longer maturities) nor maintain a
dollar-weighted, average portfolio maturity which exceeds 90 days. The Trust's
Board of Trustees has also undertaken to establish procedures reasonably
designed, taking into account current market conditions and a Fund's investment
objective, to stabilize the net asset value per Share of the Money Market Funds
for purposes of sales and redemptions at $1.00. These procedures include review
by the Trustees, at such intervals as they deem appropriate, to determine the
extent, if any, to which the net asset value per Share of each Fund calculated
by using available market quotations deviates from $1.00 per Share. In the event
such deviation exceeds one half of one percent, the Rule requires that the Board
promptly consider what action, if any, should be initiated. If the Trustees
believe that the extent of any deviation from a Fund's $1.00 amortized cost
price per Share may result in material dilution or other unfair results to new
or existing investors, they will take such steps as they consider appropriate to
eliminate or reduce to the extent reasonably practicable any such dilution or
unfair results. These steps may include selling portfolio instruments prior to
maturity, shortening the average portfolio maturity, withholding or reducing
dividends, reducing the number of a Fund's outstanding Shares without monetary
consideration, or utilizing a net asset value per Share determined by using
available market quotations.



























VALUATION OF THE EQUITY FUNDS, THE BOND FUNDS AND THE MUNICIPAL BOND FUNDS

         Except as noted below, investments of the Asset Allocation Fund, Equity
Funds, Bond Funds, and Municipal Bond Funds of the Trust in securities the
principal market for which is a securities exchange are valued at their market
values based upon the latest available sales price or, absent such a price, by
reference to the latest available bid and asked prices in the principal market
in which such securities are normally traded. Except as noted below, investments
of the International Equity Index Fund in securities the principal market for
which is a securities exchange are valued at the closing mid-market price on
that exchange on the day of computation.

         With regard to each of the above-mentioned Funds, securities the
principal market for which is not a securities exchange are valued at the mean
of their latest bid and ask quotations in such principal market. Securities and
other assets for which quotations either (1) are not readily available or (2) in
the case of the International Equity Index Fund are determined by that Fund's
Advisor or Sub-Advisor to not accurately reflect their value are valued at their
fair value as determined in good faith under consistently applied procedures
established by and under the general supervision of the Trustees of the Trust.
Short-term securities are valued at either amortized cost or original cost plus
accrued interest, which approximates current value. Mutual fund investments of
the Funds of Funds will be valued at the most recently calculated net asset
value.

                                       46
<PAGE>   292
         The value of a foreign security is determined in its national currency
as of the close of trading on the foreign exchange or other principal market on
which it is traded, which value is then converted into its U.S. dollar
equivalent at the foreign exchange closing mid-market rate reported in the
FINANCIAL TIMES as the closing rate for that date. When an occurrence subsequent
to the time a value of a foreign security was so established is likely to have
changed the value, then the fair value of those securities will be determined by
consideration of other factors by or under the direction of the Trustees of the
Trust or their delegates.

         Securities for which market quotations are readily available will be
valued on the basis of quotations provided by dealers in such securities or
furnished by a pricing service. Securities for which market quotations are not
readily available and other assets will be valued at fair value using methods
determined in good faith by the Investment Advisor under the supervision of the
Trustees and may include yield equivalents or a pricing matrix.


                      ADDITIONAL INFORMATION REGARDING THE
                    CALCULATION OF PER SHARE NET ASSET VALUE

         The net asset value of each Fund is determined and its Fiduciary Class,
Class A, Class B, Class C and Service Class Shares are priced as of the times
specified in each Fund's Prospectus. The net asset value per Share of each
Fund's Fiduciary Class, Class A, Class B, Class C and Service Class Shares is
calculated by determining the value of the respective Class's proportional
interest in the securities and other assets of the Fund, less (i) such Class's
proportional share of general liabilities and (ii) the liabilities allocable
only to such Class, and dividing such amount by the number of Shares of the
Class outstanding. The net asset value of a Fund's Fiduciary Class, Class A,
Class B, Class C and Service Class Shares may differ from each other due to the
expense of the Distribution and Shareholders Services Plan fee applicable to a
Fund's Class A, Class B, Class C and Service Class Shares.


                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

         All of the classes of Shares in each Fund (other than Class A shares of
the Income Fund and Service Class shares in the U.S. Treasury Securities Money
Market Fund and the Prime Money Market Fund) are sold on a continuous basis by
The One Group Services Company (the "Distributor"), and the Distributor has
agreed to use appropriate efforts to solicit all purchase orders.

         Fiduciary Class Shares in a Fund may be purchased, through procedures
established by the Distributor, by institutional investors, including affiliates
of BANC ONE CORPORATION and any bank, depository institution, insurance company,
pension plan or other organization authorized to act in fiduciary, advisory,
agency, custodial or similar capacities. Fiduciary Shares are not available to
Individual Retirement Accounts.

         Class A, Class B and Class C Shares (except Class A shares of the
Income Fund) may be purchased by any investor that does not meet the purchase
eligibility criteria, described above, with respect to Fiduciary Shares. Class A
shares of the Income Fund may only be purchased in connection with investment
company consolidations and reorganizations. Class C Shares are available only to
investors in the Funds of Funds. In addition to purchasing Class A, Class B and
Class C Shares directly from the Distributor, an investor may purchase Class A,
Class B and Class C Shares through a financial institution, such as a bank,
savings and loan association, insurance company (each a "Shareholder Servicing
Agent") that has established a Shareholder servicing agreement with the
Distributor, or through a broker-dealer that has established a dealer agreement
with the Distributor. Questions concerning the eligibility requirements for each
class of the Trust's Shares may be directed to the Distributor at
1-800-480-4111.

         Service Class Shares are available only in the Prime Money Market and
U.S. Treasury Securities Money Market Funds. This class of shares is available
to broker-dealers, other financial intermediaries, banks and other depository
institutions requiring special administrative and accounting services (E.G.,
sweep processing).

         As described in each Prospectus for each of the Equity and Bond Funds
and the Funds of Funds, and in the Multiple Class Plan, under certain
circumstances, Class A Shares of a Fund may be purchased free of the sales
charge applicable to such Class A Shares. No sales charge is imposed on Class A
Shares of the Funds: (i) issued through reinvestment of dividends and capital
gains distributions; (ii) acquired through the exercise of exchange privileges
where a comparable sales charge has been paid for exchanged Shares; (iii)
purchased by officers, directors or trustees, retirees and employees (and their
spouses and immediate family members) of the Trust, of BANC ONE CORPORATION and
its subsidiaries and affiliates, of the Distributor and its subsidiaries and
affiliates, of broker-dealers who have entered into a dealer agreement with the
Trust and their subsidiaries and affiliates, or of an investment sub-Advisor of
a Fund of the Trust and such sub-Advisor's subsidiaries and affiliates; (iv)
sold to affiliates of BANC ONE CORPORATION and certain accounts (other than
Individual Retirement Accounts) for which financial organizations, including any
bank, depository institution, insurance company,


                                       47
<PAGE>   293
pension plan or other organization are authorized to act in fiduciary, advisory,
agency, custodial or similar capacities, or purchased by investment Advisors,
financial planners or other intermediaries who have a dealer arrangement with
the Distributor, who place trades for their own accounts or for the accounts of
their clients and who charge a management, consulting or other fee for their
services, as well as clients of such investment Advisors, financial planners or
other intermediaries who place trades for their own accounts if the accounts are
linked to the master account of such investment Advisor, financial planner or
other intermediary; (v) purchased with proceeds from the recent redemption of
Fiduciary Class Shares of a Fund of the Trust or acquired in an exchange of
Fiduciary Class Shares of a Fund for Class A Shares of the same Fund; (vi)
purchased with proceeds from the recent redemption of Shares of a mutual fund
(other than a Fund of the Trust) for which a sales charge was paid; (vii)
purchased in an Individual Retirement Account with the proceeds of a
distribution from an employee benefit plan, provided that, at the time of
distribution, the employee benefit plan had plan assets invested in a Fund of
the Trust; (viii) purchased with Trust assets; (ix) purchased in accounts as to
which a bank or broker-dealer charges an asset allocation fee, provided the bank
or broker-dealer has an agreement with the Distributor; (x) purchased in
connection with plans of reorganization of a Fund, such as mergers, asset
acquisitions and exchange offers to which a Fund is a party.

         An investor relying upon any of the categories of waivers of the sales
charge must qualify for such waiver in advance of the purchase with the
Distributor or the financial institution or intermediary through which Shares
are purchased by the investor.

         The waiver of the sales charge under circumstances (v), (vi), and (vii)
above applies only if the purchase is made within 60 days of the redemption and
if conditions imposed by the Distributor are met. The waiver policy with respect
to the purchase of Shares through the use of proceeds from a recent redemption
or distribution as described in clauses (v), (vi), and (vii) above will not be
continued indefinitely and may be discontinued at any time without notice.
Investors should call the Distributor at 1-800-480-4111 to determine whether
they are eligible to purchase Shares without paying a sales charge through the
use of proceeds from a recent redemption or distribution as described above, and
to confirm continued availability of these waiver policies prior to initiating
the procedures described in clauses (v), (vi), and (vii).

         Fiduciary Class Shareholders of a Fund may exchange their Shares for
Class A Shares of the same Fund or for Class A Shares or Fiduciary Class Shares
of another Fund of the Trust. Class A Shareholders may exchange their Shares for
Fiduciary Class Shares of a Fund or for Fiduciary Class or Class A Shares of
another Fund or the Trust, if the Shareholder is eligible to purchase such
Shares. If a Class A Shareholder of the Income Fund exchanges his or her Shares
within one year of receipt of the Shares, the Shareholder will be assessed a 2%
redemption fee. The exchange privilege may be exercised only in those states
where the Shares of the Fund or such other Fund may be legally sold. All
exchanges discussed herein are made at the net asset value of the exchanged
Shares, except as provided below. The Trust does not impose a charge for
processing exchanges of Shares. If a Shareholder seeks to exchange Class A
Shares of a Fund that does not impose a sales charge for Class A Shares of a
Fund that does, or the Fund being exchanged into has a higher sales charge, the
Shareholder will be required to pay a sales charge in the amount equal to the
difference between the sales charge applicable to the Fund into which the Shares
are being exchanged and any sales charge previously paid for the exchanged
Shares, including any sales charges incurred on any earlier exchanges of the
Shares (unless such sales charge is otherwise waived as provided above). The
exchange of Fiduciary Class Shares for Class A Shares also will require payment
of the sales charge unless the sales charge is waived, as provided above. If a
Shareholder (no longer eligible to purchase Fiduciary Shares) purchases Class A
Shares of a Fund, the Shareholder will be subject to Distribution and
Shareholder Services Plan Fees.

         Class B Shareholders of a Fund may exchange their Shares for Class B
Shares of any other Fund of the Trust on the basis of the net asset value of the
exchanged Class B Shares, without the payment of any Contingent Deferred Sales
Charge that might otherwise be due upon redemption of the outstanding Class B
Shares. The newly acquired Class B Shares will be subject to the higher
Contingent Deferred Sales Charge of either the Fund from which the Shares were
exchanged or the Fund into which the Shares were exchanged. With respect to
outstanding Class B Shares as to which previous exchanges have taken place,
"higher Contingent Deferred Sales Charge" shall mean the higher of the
Contingent Deferred Sales Charge applicable to either the Fund the Shares are
exchanging into or any other Fund from which the Shares previously have been
exchanged. For purposes of computing the Contingent Deferred Sales Charge that
may be payable upon a disposition of the newly acquired Class B Shares, the
holding period for outstanding Class B Shares of the Fund from which the
exchange was made is "tacked" to the holding period of the newly acquired Class
B Shares. For purposes of calculating the holding period applicable to the newly
acquired Class B Shares, the newly acquired Class B Shares shall be deemed to
have been issued on the date of receipt of the Shareholder's order to purchase
the outstanding Class B Shares of the Fund from which the initial exchange was
made.

         Class C Shareholders may not exchange their Class C Shares for shares
of any other class nor may shares of any other class be exchanged for Class C
Shares.

         Service Class Shareholders may not exchange their Service Class Shares
for Shares of any other class, nor may Shares of any other class be exchanged
for Service Class Shares.

<PAGE>   294
         Shares of the Institutional Money Market Funds may be purchased by
commercial and retail institutional investors, including affiliates of BANC ONE
CORPORATION, that have opened an account with the Transfer Agent either directly
or through a Shareholder Servicing Agent, by persons whose individual net worth,
or joint net worth with that person's spouse, at the time of his or her purchase
exceeds $1,000,000, or by persons whose individual annual income, or joint
annual income with that person's spouse, at the time of his or her purchase
exceeds $200,000.

         The Trust may suspend the right of redemption or postpone the date of
payment for Shares during any period when (a) trading on the New York Stock
Exchange (the "Exchange") is restricted by applicable rules and regulations of
the Securities and Exchange Commission, (b) the Exchange is closed for other
than customary weekend and holiday closings, (c) the Securities and Exchange
Commission has by order permitted such suspension, or (d) an emergency exists as
determined by the Securities and Exchange Commission.

         The Trust may redeem Shares involuntarily if redemption appears
appropriate in light of the Trust's responsibilities under the 1940 Act. (See
"Valuation of the Money Market and Institutional Money Market Funds and the
Municipal Money Market Fund" above.)

                             MANAGEMENT OF THE TRUST

TRUSTEES & OFFICERS

         Overall responsibility for management of the Trust rests with the Board
of Trustees of the Trust, who are elected by the Shareholders of the Trust.
There are currently four Trustees, all of whom are not "interested persons" of
the Trust within the meaning of that term under the 1940 Act. The Trustees, in
turn, elect the officers of the Trust to supervise actively its day-to-day
operations.

         The Trustees of the Trust, their addresses, and principal occupations
during the past five years are set forth below.

         All investment advisory services are provided to the Funds by Banc One
Advisors pursuant to an investment advisory agreement dated January 11, 1993
(the "Investment Advisory Agreement"). The Investment Advisory Agreement (and
the Sub-Investment Advisory Agreement described immediately following,
collectively, the "Advisory and Sub-Advisory Agreements") will continue in
effect as to a particular Fund from year to year, if such continuance is
approved at least annually by the Trust's Board of Trustees or by vote of a
majority of the outstanding Shares of such Fund (as defined under "ADDITIONAL
INFORMATION--Miscellaneous" in this Statement of Additional Information), and a
majority of the Trustees who are not parties to the respective investment
advisory agreements or interested persons (as defined in the Investment Company
Act of 1940) of any party to the respective investment advisory agreements by
votes cast in person at a meeting called for such purpose. The Advisory and
Sub-Advisory Agreements were renewed by the Trust's Board of Trustees at their
quarterly meeting on August 17, 1995. The Advisory and Sub-Advisory Agreements
are terminable as to a particular Fund at any time on 60 days' written notice
without penalty by the Trustees, by vote of a majority of the outstanding Shares
of that Fund, or by the Fund's Advisor or Sub-Advisor as the case may be. The
Advisory and Sub-Advisory Agreements also terminate automatically in the event
of any assignment, as defined in the 1940 Act.

         The Advisory and Sub-Advisory Agreements each provide that the
respective Advisor or Sub-Advisor shall not be liable for any error of judgment
or mistake of law or for any loss suffered by the Trust in connection with the
performance of the respective investment advisory agreements, except a loss
resulting from a breach of fiduciary duty with respect to the receipt of
compensation for services or a loss resulting from willful misfeasance, bad
faith, or gross negligence on the part of Banc One Advisors or Sub-Advisor in
the performance of its duties, or from reckless disregard by it of its duties
and obligations thereunder.

Advisors for the fiscal year ended June 30, 1995 and $26,251 in sub-advisory
fees from Banc One Advisors for the fiscal year ended June 30, 1996.

         Independence International Associates, Inc.

         Independence International Associates, Inc. ("Independence
International") serves as investment Sub-Advisor to the International Equity
Index Fund pursuant to an agreement with Banc One Advisors dated January 11,
1993. Independence International is a wholly-owned subsidiary of John Hancock
Asset Management, Inc. and an indirect, wholly-owned subsidiary of John Hancock
Mutual Life Insurance Company. Boston International Advisors, Inc., the
predecessor of Independence International, received $161,906 in sub-advisory
fees from Banc One Advisors for the fiscal year ended June 30, 1995, $212,352 in
sub-advisory fees from Banc One Advisors for the fiscal year ended June 30,
1996; and $315,098 in sub-advisory fees from Banc One Advisors for the fiscal

GLASS-STEAGALL ACT

         In 1971 the United States Supreme Court held in INVESTMENT COMPANY
INSTITUTE V. CAMP that the federal statute commonly referred to as the
Glass-Steagall Act prohibits a national bank from operating a Fund for the
collective investment of managing agency accounts. Subsequently, the Board of
Governors of the Federal Reserve System (the "Board") issued a regulation and
interpretation to the effect that the Glass-Steagall Act and such decision: (a)
forbid a bank holding company registered under the Federal Bank Holding Company
Act of 1956 (the "Holding Company Act") or any non-bank affiliate thereof from
sponsoring, organizing, or controlling a registered, open-end investment company
continuously engaged in the issuance of its Shares, but (b) do not prohibit such
a holding company or affiliate from acting as investment Advisor, transfer
agent, and custodian to such an investment company. In 1981, the United States
Supreme Court held in BOARD OF GOVERNORS OF THE FEDERAL RESERVE SYSTEM V.
INVESTMENT COMPANY INSTITUTE that the Board did not exceed its authority under
the Holding Company Act when it adopted its regulation and interpretation
authorizing bank holding companies and their non-bank affiliates to act as
investment Advisors to registered closed-end investment companies. In the BOARD
OF GOVERNORS case, the Supreme Court also stated that if a national bank
complied with the restrictions imposed by the Board in its regulation and
interpretation authorizing bank holding companies and their non-bank affiliates
to act as investment Advisors to investment companies, a national bank
performing investment advisory services for an investment company would not
violate the Glass-Steagall Act. In addition, state securities laws on this issue
may differ from the interpretations of federal law expressed herein and banks
and financial institutions may be required to register as dealers pursuant to
state law.

         In the Investment Advisory Agreement with the Trust, Banc One Advisors
has represented to the Trust that it possesses the legal authority to perform
the investment advisory services contemplated by the agreement and described in
the Prospectuses and this Statement of Additional Information without violation
of applicable statutes and regulations. Future changes in either federal or
state statutes and regulations relating to the permissible activities of banks
or bank holding companies and the subsidiaries or affiliates of those entities,
as well as further judicial or administrative decisions or interpretations of
present and future statutes and regulations, could prevent or restrict Banc One
Advisors from continuing to perform such services for the Trust. Depending upon
the nature of any changes in the services which could be provided


                                       55
<PAGE>   301
by Banc One Advisors, the Board of Trustees of the Trust would review the
Trust's relationship with Banc One Advisors and consider taking all action
necessary in the circumstances.

         Should future legislative, judicial, or administrative action prohibit
or restrict the proposed activities of BANC ONE CORPORATION subsidiary banks or
their correspondent banks in connection with customer purchases of Shares of the
Trust, these banks might be required to alter materially or discontinue the
services offered by them to customers. It is not anticipated, however, that any
change in the Trust's method of operations would affect its net asset value per
Share or result in financial losses to any customer.

PORTFOLIO TRANSACTIONS

         Pursuant to the Advisory and Sub-Advisory Agreements, Banc One Advisors
and the Sub-Advisor determine, subject to the general supervision of the Board
of Trustees of the Trust and in accordance with each Fund's investment objective
and restrictions, which securities are to be purchased and sold by each such
Fund and which brokers are to be eligible to execute its portfolio transactions.
Purchases and sales of portfolio securities with respect to the Money Market
Funds, the Bond Funds, the Funds of Funds and (to a varying degree) the Asset
Allocation Fund usually are principal transactions in which portfolio securities
are purchased directly from the issuer or from an underwriter or market maker
for the securities. Purchases from underwriters of portfolio securities
generally include (but not in the case of mutual fund shares purchased by the
Funds of Funds) a commission or concession paid by the issuer to the underwriter
and purchases from dealers serving as market makers may include the spread
between the bid and asked price. Transactions on stock exchanges (other than
certain foreign stock exchanges) involve the payment of negotiated brokerage
commissions. Transactions in the over-the-counter market are generally principal
transactions with dealers. With respect to the over-the-counter market, the
Trust, where possible, will deal directly with the dealers who make a market in
the securities involved except in those circumstances where better price and
execution are available elsewhere. While the Banc One Advisors generally seeks
competitive spreads or commissions, the Trust may not necessarily pay the lowest
spread or commission available on each transaction, for reasons discussed below.


         Allocation of transactions, including their frequency, to various
dealers is determined by Banc One Advisors and the Sub-Advisor with respect to
the Funds each serves based on their best judgment and in a manner deemed fair
and reasonable to Shareholders. The primary consideration is prompt execution of
orders in an effective manner at the most favorable price. Subject to this
consideration, dealers who provide supplemental investment research to Banc One
Advisors or the Sub-Advisor may receive orders for transactions by the Trust,
even if such dealers charge commissions in excess of the lowest rates available,
provided such commissions are reasonable in light of the value of brokerage and
research services received. Such research services may include, but are not be
limited to, analysis and reports concerning economic factors and trends,
industries, specific securities, and portfolio strategies. Information so
received is in addition to and not in lieu of services required to be performed
by Banc One Advisors or the Sub-Advisor and does not reduce the advisory fees
payable to Banc One Advisors or the Sub-Advisor. Such information may be useful
to Banc One Advisors or the Sub-Advisor in serving both the Trust and other
clients and, conversely, supplemental information obtained by the placement of
business of other clients may be useful to Banc One Advisors or the Sub-Advisor
in carrying out their obligations to the Trust. In the last fiscal year, Banc
One Advisors directed brokerage commissions to brokers who provided research
services to Banc One Advisors. Total compensation paid to such brokers amounted
to $15,142,680.

         The Trust will not execute portfolio transactions through, acquire
portfolio securities issued by, make savings deposits in, or enter into
repurchase or reverse repurchase agreements with its Advisors or their
affiliates except as may be permitted under the 1940 Act, and will not give
preference to correspondents of BANC ONE CORPORATION subsidiary banks with
respect to such transactions, securities, savings deposits, repurchase
agreements, and reverse repurchase agreements.

         During the Trust's fiscal year ended June 30, 1995, the Trust paid
brokerage commissions to Goldman for brokerage services provided as follows:

Fund believes to be equitable to the Fund(s) and such other investment company
or account. In some instances, this investment procedure may adversely affect
the price paid or received by a Fund or the size of the position obtained by a
Fund. To the extent permitted by law, Banc One Advisors and the Sub-Advisor may
aggregate the securities to be sold or purchased by it for a Fund with those to
be sold or purchased by it for other Funds or for other investment companies or
accounts in order to obtain best execution. As provided by the Investment
Advisory and Sub-Advisory Agreements, in making investment recommendations for
the Trust, Banc One Advisors and the Sub-Advisor will not inquire or take into
consideration whether an issuer of securities proposed for purchase or sale by
the Trust is a customer of Banc One Advisors or the Sub-Advisor or their parents
or subsidiaries or affiliates and, in dealing with its commercial customers,
Banc One Advisors and the Sub-Advisor and their respective parent, subsidiaries,
and affiliates will not inquire or take into consideration whether securities of
such customers are held by the Trust.

ADMINISTRATOR

         The One Group Services Company serves as Administrator (the
"Administrator") to each Fund of the Trust pursuant to a Management and
Administration Agreement with the Trust (the "Administration Agreement"). The
Board of Trustees of the Trust approved The One Group Services Company as the
sole Administrator for each Fund beginning December 1, 1995. The Administrator
assists in supervising all operations of each Fund to which it serves as
Administrator (other than those performed under the respective investment
advisory agreements and Custodian and Transfer Agency Agreements for that Fund).

         Under the Administration Agreement, the Administrator has agreed to
price the portfolio securities of each Fund it serves and to compute the net
asset value and net income of such Funds on a daily basis, to maintain office
facilities for the Trust, to maintain each such Fund's financial accounts and
records, and to furnish the Trust statistical and research data, data
processing, clerical, accounting, and bookkeeping services, and certain other
services required by the Trust with respect to each such Fund. The Administrator
prepares annual and semi-annual reports to the Securities and Exchange
Commission, prepares federal and State tax returns, prepares filings with State
securities commissions, and generally assists in all aspects of the Trust's
operations other than those performed under the investment advisory agreements,
and Custodian and Transfer Agency Agreements. Under the Administration
Agreement, the Administrator may delegate all or any part of its
responsibilities thereunder.

         Banc One Advisors also serves as Sub-Administrator to each Fund of the
Trust, pursuant to an agreement between the Administrator and Banc One Advisors.
Pursuant to this agreement, Banc One Advisors performs many of the
Administrator's duties, for which Banc One Advisors receives a fee paid by the
Administrator.

         Unless sooner terminated, the Administration Agreement between the
Trust and The One Group Services Company will continue in effect through
November 30, 1997. The Administration Agreement thereafter shall be renewed
automatically for successive one year terms, unless written notice not to renew
is given by the non-renewing party to the other party at least sixty days prior
to the expiration of the then-current term. The Administration Agreement will be
reviewed and ratified at least annually by the Trust's Board of Trustees,
provided that the Administration Agreement is also reviewed and ratified by the
majority of the Trust's Trustees who are not parties to the Administration
Agreement or interested persons (as defined in the 1940 Act) of any party to the
Administration Agreement, by vote cast in person at a meeting called for the
purpose of reviewing and ratifying the Administration Agreement. The
Administration Agreement is terminable with respect to a particular Trust only
upon mutual agreement of the parties to the Administration Agreement and for
cause (as defined in the Administration Agreement) by the party alleging cause,
on not less than sixty days' notice by the Trust's Board of Trustees or by The
One Group Services Company.

         The Administration Agreement provides that the Administrator shall not
be liable for any error of judgment or mistake of law or any loss suffered by
the Trust in connection with the matters to which the Administration Agreement
relates, except a loss resulting from willful misfeasance, bad faith, or
negligence in the performance of its duties, or from the reckless disregard by
it of its obligations and duties thereunder.

DISTRIBUTOR

         The One Group Services Company serves as Distributor to each Fund of
the Trust pursuant to its Distribution Agreement with the Trust (the
"Distribution Agreement"). The Board of Trustees of the Trust approved The One
Group Services Company as the sole Distributor beginning November 1, 1995.
Unless otherwise terminated, the Distribution Agreement will continue in effect
until November 30, 1997 and will continue from year to year if approved at least
annually (i) by the Trust's Board of Trustees or by the vote of a majority of
the outstanding Shares of the Funds (see "ADDITIONAL INFORMATION--
Miscellaneous," in this Statement of Additional Information) that are parties to
the Distribution Agreement, and (ii) by the vote of a majority of the Trustees
of the Trust who are not parties to the Distribution Agreement or interested
persons of any such party, cast in person at a meeting called for the purpose of
voting on such approval. The agreement may be terminated in the event of its
assignment, as defined in the 1940 Act. The One Group Services Company is a
broker-dealer registered with the Securities and Exchange Commission, and is a
member of the National Association of Securities Dealers, Inc.

DISTRIBUTION PLAN

         The operation and fees with respect to Class A Shares, Class B Shares,
Class C Shares, and Service Class Shares of the Trust payable under the Trust's
Distribution and Shareholder Services Plans, to which Class A Shares, Class B
Shares, Class C Shares, and Service Class Shares of each Fund of the Trust are
subject, are described in each such Fund's Prospectuses and in the Multiple
Class Plan.

         The Distribution and Shareholder Services Plan with respect to Class A
Shares (the "Distribution Plan") was initially approved on July 28, 1989 by the
Trust's Board of Trustees, including a majority of the Trustees who are not
interested persons of the Trust (as defined in the 1940 Act) and who have no
direct or indirect financial interest in the Distribution Plan (the "Independent
Trustees"). The Distribution Plan originally applied to the single class of
Shares of each Fund of the Trust that existed prior to the offering of the
Funds' Shares as five separate classes. An amendment to the Distribution Plan
was approved by the Independent Trustees on October 21, 1991, and became
effective on February 7, 1992. Such amendment limited fees under the
Distribution Plan only to the Class A Shares of each Fund. The Distribution Plan
was amended again on February 11, 1993 in order to make Retirement Class Shares
(now the Service Class Shares) subject to distribution fees. The Distribution
Plan was further amended on February 29, 1996, to eliminate certain "defensive"
provisions of the Distribution Plan. A Distribution and Shareholder Services
Plan (the "CDSC Plan") for Class B and Class C Shares was initially approved on
August 12, 1993 by the Independent Trustees. The CDSC Distribution Plan was
re-executed on December 13, 1995 and amended on February 20, 1997. Prior to

CUSTODIAN AND TRANSFER AGENT

         Cash and securities owned by the Funds of the Trust are held by State
Street Bank and Trust Company ("State Street") as Custodian. State Street serves
the respective Funds as Custodian pursuant to a Custodian Agreement with the
Trust (the "Custodian Agreement"). Under the Custodian Agreement, State Street
(i) maintains a separate account or accounts in the name of each Fund; (ii)
makes receipts and disbursements of money on behalf of each Fund; (iii) collects
and receives all income and other payments and distributions on account of the
Funds' portfolio securities; (iv) responds to correspondence from security
brokers and others relating to its duties; and (v) makes periodic reports to the
Trust's Board of Trustees concerning the Trust's operations. State Street may,
at its own expense, open and maintain a sub-custody account or accounts on
behalf of the Trust, provided that State Street shall remain liable for the
performance of all of its duties under the Custodian Agreement.

         Bank One Trust Company, N.A. serves as Sub-Custodian in connection with
the Trust's securities lending activities, pursuant to an agreement between
State Street and Bank One Trust Company. Bank One Trust Company receives a fee
paid by the Trust.

         Rules adopted under the 1940 Act permit the Trust to maintain its
securities and cash in the custody of certain eligible banks and securities
depositories. The Trust intends to select foreign custodians or sub-custodians
to maintain foreign securities of the International Equity Index Fund pursuant
to such rules, following a consideration of a number of factors, including, but
not limited to, the reliability and financial stability of the institution; the
ability of the institution to perform custodial services for the Trust; the
reputation of the institution in its national market; the political and economic
stability of the country in which the institution is located; and the risks of
potential nationalization or expropriation of Trust assets. In addition, the
1940 Act requires that foreign bank sub-custodians, among other things have
Shareholder equity in excess of $200 million, have no lien on the Trust's assets
and maintain adequate and accessible records.

         State Street Bank & Trust ("State Street") serves as Transfer Agent and
Dividend Disbursing Agent for each Fund pursuant to Transfer Agency Agreements
with the Trust (the "Transfer Agency Agreement"). Under the Transfer Agency
Agreements, State Street has agreed (i) to issue and redeem Shares of the Trust;
(ii) to address and mail all communications by the Trust to its Shareholders,
including reports to Shareholders, dividend and distribution notices, and proxy
material for its meetings of Shareholders; (iii) to respond to correspondence or
inquiries by Shareholders and others relating to its duties; (iv) to maintain
Shareholder accounts and certain sub-accounts; and (v) to make periodic reports
to the Trust's Board of Trustees concerning the Trust's operations.

                             ADDITIONAL INFORMATION

DESCRIPTION OF SHARES

         The Trust is a Massachusetts Business Trust. The Trust's Declaration of
Trust was filed with the Secretary of State of the Commonwealth of Massachusetts
on May 23, 1985 and authorizes the Board of Trustees to issue an unlimited
number of Shares, which are units of beneficial interest, without par value. The
Trust's Declaration of Trust authorizes the Board of Trustees to establish one
or more series of Shares of the Trust, and to classify or reclassify any series
into one or more classes by setting or changing in any one or more respects the
preferences, designations, conversion, or other rights, restrictions, or
limitations as to dividends, conditions of redemption, qualifications, or other
terms applicable to the Shares of such class, subject to those matters expressly
provided for in the Declaration of Trust, as amended, with respect to the Shares
of each series of the Trust. The Trust presently includes 40 series of Shares,
which represent interests in the Prime Money Market Fund, the U.S. Treasury
Securities Money Market Fund, the Municipal Money Market Fund, the Ohio
Municipal Money Market Fund, the Income Equity Fund, the Disciplined Value Fund,
the Growth Opportunities Fund, the Value Growth Fund, the Small Capitalization
Fund, the Large Company Value Fund, the Large Company Growth Fund, the
International Equity Index Fund, the Equity Index Fund, the Asset Allocation
Fund, the Income Bond Fund, the Limited Volatility Bond Fund, the Intermediate
Bond Fund, the Government Bond Fund, the Ultra Short-Term Income Fund, the
Income Fund, the Investor Growth Fund, the Investor Growth & Income Fund, the
Investor Aggressive Growth Fund, the Investor Fixed Income Fund, the Investor
Conservative Growth Fund, the Investor Balanced Fund, the Municipal Income Fund,
the Intermediate Tax-Free Bond Fund, the Ohio Municipal Bond Fund, the Texas
Tax-Free Bond Fund, the West Virginia Municipal Bond Fund, the Kentucky
Municipal Bond Fund, the Louisiana Municipal Bond Fund, the Arizona Municipal
Bond Fund, the Treasury Money Market Fund, the Treasury Only Money Market Fund,
the Government Money Market Fund, the Tax Exempt Money Market Fund, the
Institutional Prime Money Market Fund and the Treasury and Agency Fund. The
Funds of the Trust (other than the Institutional Money Market Funds, the U.S.
Treasury Securities Money Market Fund, the Prime Money Market Fund, the
Municipal Money Market Fund and the Ohio Municipal Money Market Fund) offer
Shares in four separate classes: Fiduciary Shares, Class A Shares, Class B and
Class C Shares. The U.S. Treasury Securities Money Market Fund and the Prime
Money Market Fund offer Fiduciary Class Shares, Class A Shares, Class B Shares,
Class C Shares, Fiduciary Class Shares and Service Class Shares. The
Institutional Money Market Funds offer only Fiduciary Class Shares. The
Municipal Money Market Fund and the Ohio Municipal Money Market Funds offer
Fiduciary Class, Class A and Class C Shares. See the relevant Prospectus for
those Funds for more details.

         Shares have no subscription or preemptive rights and only such
conversion or exchange rights as the Board may grant in its discretion. When
issued for payment as described in the Prospectus and this Statement of
Additional Information, the Trust's Shares will be fully paid and
non-assessable. In the event of a liquidation or dissolution of the Trust,
Shares of a Fund are entitled to receive the assets available for distribution
belonging to the Fund, and a proportionate distribution, based upon the relative
asset values of the respective Funds, of any general assets not belonging to any
particular Fund which are available for distribution.

         Rule 18f-2 under the 1940 Act provides that any matter required to be
submitted to the holders of the outstanding voting securities of an investment
company such as the Trust shall not be deemed to have been effectively acted
upon unless approved by the holders of a majority of the outstanding Shares of
each Fund affected by the matter. For purposes of determining whether the
approval of a majority of the outstanding Shares of a Fund will be required in
connection with a matter, a Fund will be deemed to be affected by a matter
unless it is clear that the interests of each Fund in the matter are identical,
or that the matter does not affect any interest of the Fund. Under Rule 18f-2,
the approval of an investment advisory agreement or any change in investment
policy would be effectively acted upon with respect to a Fund only if approved
by a majority of the outstanding Shares of such Fund. However, Rule 18f-2 also
provides that the ratification of independent public accountants, the approval
of principal underwriting contracts, and the election of Trustees may be
effectively acted upon by Shareholders of the Trust voting without regard to
series.

         Class A Shares, Class B Shares, Class C Shares and Service Class Shares
of a Fund have exclusive voting rights with respect to matters pertaining to the
Fund's Distribution Plan.

SHAREHOLDER AND TRUSTEE LIABILITY

         Under Massachusetts law, holders of units of beneficial interest in a
business trust may, under certain circumstances, be held personally liable as
partners for the obligations of the trust. However, the Trust's Declaration of
Trust provides that Shareholders shall not be subject to any personal liability
for the obligations of the Trust, and that every written agreement, obligation,
instrument, or undertaking made by the Trust shall contain a provision to the
effect that the Shareholders are not personally liable thereunder. The
Declaration of Trust provides for indemnification out of the trust property of
any Shareholder held personally liable solely by reason of his being or having
been a Shareholder. The Declaration of Trust also provides that the Trust shall,
upon request, assume the defense of any claim made against any Shareholder for
any act or obligation of the Trust, and shall satisfy any judgment thereon.
Thus, the risk of a Shareholder incurring financial loss on account of
Shareholder liability is limited to circumstances in which the Trust itself
would be unable to meet its obligations.


                                       66
<PAGE>   312
         The Declaration of Trust states further that no Trustee, officer, or
agent of the Trust shall be personally liable in connection with the
administration or preservation of the assets of the trust or the conduct of the
Trust's business; nor shall any Trustee, officer, or agent be personally liable
to any person for any action or failure to act except for his own bad faith,
willful misfeasance, gross negligence, or reckless disregard of his duties. The
Declaration of Trust also provides that all persons having any claim against the
Trustees or the Trust shall look solely to the assets of the trust for payment.

PERFORMANCE

         From time to time, the Funds may advertise yield, total return and/or
distribution rate. These figures will be based on historical earnings and are
not intended to indicate future performance. The yield of a Fund refers to the
annualized income generated by an investment in the Fund over a specified 30-day
period. The yield is calculated by assuming that the income generated by the
investment during that period is generated over a one-year period and is shown
as a percentage of the investment.

         Total return is the change in value of an investment in a Fund over a
given period, assuming reinvestment of any dividends and capital gains. A
cumulative total return reflects an actual rate of return over a stated period
of time. An average annual total return is a hypothetical rate of return that,
if achieved annually, would have produced the same cumulative total return if
performance had been constant over the entire period. Average annual total
returns smooth out variations in performance; they are not the same as actual
year-by-year results.

         The distribution rate is computed by dividing the total amount of the
dividends per share paid out during the past period by the maximum offering
price or month-end net asset value depending on the class of a Fund. This figure
is then "annualized" (multiplied by 365 days and divided by the applicable
number of days in the period). Funds with a front-end sales charge would
incorporate the offering price into the distribution yield in place of month-end
net asset value.

         Distribution rate is a measure of the level of income paid out in cash
to Shareholders over a specified period. It differs from yield and total return
and is not intended to be a complete measure of performance. Furthermore, the
distribution rate may include return of principal and/or capital gains. Total
return is the change in value of a hypothetical investment over a given period
assuming reinvestment of dividends and capital gain distributions. The yield
refers to the cumulative 30-day rolling net investment income, divided by
maximum offering price and multiplied by average shares outstanding during this
period.

         Further information about the performance of each class of the Funds is
contained in the Trust's Annual Report to Shareholders for The One Group, which
may be obtained without charge by calling 1-800-480-4111.

CALCULATION OF PERFORMANCE DATA

         The yield for each Money Market Funds, and the Institutional Money
Market Funds was computed with respect to each class of Shares by determining
the percentage net change, excluding capital changes, in the value of an
investment in one Share of the particular class of the Fund over the base
period, and multiplying the net change by 365/7 (or approximately 52 weeks). The
effective yield of each class of each Fund represents a compounding of the yield
by adding 1 to the number representing the percentage change in value of the
investment during the base period, raising that sum to a power equal to 365/7,
and subtracting 1 from the result. No performance data is available with respect
to the Tax Exempt Money Market, Treasury Money Market and Institutional Prime
Money Market Fund because those Funds had not commenced operations as of June
30, 1997.

(1) A portion of the income may be subject to alternative minimum tax.
(2) Data for performance purposes begins 1/1/87 (Fiduciary Class).

         The tax equivalent yields for the classes of the Municipal Money
Market, Ohio Municipal Money Market, and Tax Exempt Money Market Funds are
computed by dividing that portion of the Fund's yield (with respect to a
particular class) which is tax-exempt by 1 minus a stated income tax rate and
adding the product to that portion, if any, of the yield of the Fund (with
respect to a particular class) that is not tax-exempt. The tax equivalent yields
for the classes of the Municipal Money Market Fund contained in the following
paragraph were computed based on an assumed effective federal income tax rate of
39.6%. No such data was provided for the Tax Exempt Money Market Fund because it
had not commenced operations as of June 30, 1997. The tax equivalent effective
yield for the classes of the Municipal Money Market Fund, Ohio Municipal Money
Market Fund, and Tax Exempt Money Market Funds are computed by dividing that
portion of the effective yield of the Fund (with respect to a particular class)
which is tax-exempt by 1 minus a stated income tax rate and adding the product
to that portion, if any, of the effective yield of the Fund (with respect to a
particular class) that is not tax-exempt.

         The performance of the funds may be compared in publications to the
performance of various indices and investments (such as other mutual funds) for
which reliable performance data is available, as well as averages, performance
rankings or other information prepared by recognized mutual fund statistical
services, as set forth below.

         Performance information showing a Fund's total return and/or 30-day
yield with respect to a particular class may be presented from time to time in
advertising and sales literature regarding the Equity Funds, the Bond Funds, the
Funds of Funds, and the Municipal Bond Funds. A 30-day yield is calculated by
dividing the net investment income per-share earned during the 30-day base
period by the maximum offering price per share on the last day of the period,
according to the following formula:

                                          a-b
                                         ------
                        30-Day Yield = 2[(cd +1)6-1]

         In the above formula, "a" represents dividends and interest earned by a
particular class during the 30-day base period; "b" represents expenses accrued
to a particular class for the 30-day base period (net of reimbursements); "c"
represents the average daily number of Shares of a particular class outstanding
during the 30-day base period that were entitled to receive dividends; and "d"
represents the maximum offering price per share of a particular class on the
last day of the 30-day base period.

         From time to time the tax equivalent 30-day yield of a particular class
of a Municipal Bond Fund may be presented in advertising and sales literature.
The tax equivalent 30-day yield will be computed by dividing that portion of a
Fund's yield (respecting a particular class) which is tax-exempt by 1 minus a
stated income tax rate and adding the product to that portion, if any, of the
yield of the Fund (respecting a particular class) that is not tax-exempt. The
tax equivalent 30-day yields for a Municipal Bond Fund (respecting a particular
class) will, unless otherwise noted, be computed based on an assumed effective
federal income tax rate of 31%. No tax equivalent 30-day yield information is
available for the Texas Tax-Free Bond Fund.

         A Fund's respective cumulative total return and average annual total
return was determined by calculating the change in the value of a hypothetical
$1,000 investment in a particular class of the Fund for each of the periods
shown. Cumulative total return for a particular class of a Fund is computed by
determining the rate of return over the applicable period that would equate the
initial amount invested to the ending redeemable value of the investment. The
cumulative return is calculated as the total dollar increase or decrease in the
value of an account assuming reinvestment of all distributions divided by the
original initial investment. The average annual return for a particular class of
a Fund is computed by determining the average annual compounded rate of return
over the applicable period that would equate the initial amount invested to the
ending redeemable value of the investment. The ending redeemable value includes
dividends and capital gain distributions reinvested at net asset value. The
resulting percentages indicated the positive or negative investment results that
an investor would have experienced from changes in share price and reinvestment
of dividends and capital gains distributions.

    (1)The quoted performance of these funds ("Mutual Funds") advised by Banc
    One Investment Advisors Corporation includes performance of certain
    collective trust fund ("Commingled") accounts for periods dating back to
    12/31/83 for the West Virginia Municipal Bond Fund, 11/30/79 the Arizona
    Municipal Bond Fund and 4/30/88 for the Treasury & Agency Fund. Prior to the
    Mutual Funds commencement of for operations on 1/21/97, the Commingled
    accounts were adjusted to reflect the expenses associated with the Mutual
    Funds. The Commingled accounts were not registered with the Securities and
    Exchange Commission and, therefore, were not subject to the investment
    restrictions imposed by law on registered mutual funds. If the Commingled
    accounts had been registered, the Commingled accounts' performance may have
    been adversely affected.

    (2)A portion of the income may be subject to the federal alternative minimum
    tax.

    (3)Foreign investing involves a greater degree of risk and volatility.


    Performance information showing a Fund's and/or particular Class's
distribution rate may be presented from time to time in advertising and sales
literature regarding the Bond Funds and Equity Funds. The distribution rate is
calculated as follows:

                distribution yield = a/(b) x 365
                                     -----------
                                          c

    In the formula, "a" represents dividends distributed by a particular
class during that period; "b" represents month end offer price or net asset
value for a particular class; "c" represents the number of days in the period
being calculated. "365" is the number of days in a year, used to annualize the
distribution yield.

    Performance will fluctuate from time to time and is not necessarily
representative of future results. Accordingly, a Fund's performance may not
provide for comparison with bank deposits or other investments that pay a fixed
return for a stated period of time. Performance is a function of a Fund's
quality, composition, and maturity, as well as expenses allocated to the Fund.
Fees imposed upon customer accounts at a bank, with regard to Fiduciary Class
Shares and Service Class Shares, or a Participating Organization, with regard to
Class A and Class B Shares, will reduce a Fund's effective yield to customers.
Performance data for the Funds through June 30, 1997 (calculated as described
above) is as follows:


                                       73
<PAGE>   319
The above quoted performance for the Arizona Municipal Bond Fund, the West
Virginia Municipal Bond Fund, and the Treasury & Agency Fund, respectively,
includes the performance for the Arizona Municipal Bond Investment Fund, the
West Virginia Municipal Bond Investment Fund and the Treasury Only Government
Based Investment Trust, common trust funds managed by Banc One Advisors
(collectively the "CIFs"). The quoted performance of these Funds include
performance of the corresponding CIFs for periods dating back to December 31,
1983 for the West Virginia Municipal Bond Fund, November 30, 1979 for the
Arizona Municipal Bond Fund and April 30, 1988 for the Treasury & Agency Fund.
Because the management of the Funds is substantially the same as the CIFs, the
quoted performance of the Funds will include the performance of the CIFs for the
periods prior to January 20, 1997, the effectiveness of the Trust's registration
statement as it relates to the Funds. The quoted performance will be adjusted to
reflect the deduction of estimated current fees of the Funds on a class by class
basis absent any waivers. The CIFs were not registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), and therefore were not subject
to certain investment restrictions, limitations, and diversification
requirements that are imposed by the 1940 Act and the Code. If the CIFs had been
so registered, their performance might have been adversely affected.

         In addition, the performance of each class of a Fund may from time to
time be compared to that of other mutual funds tracked by mutual fund rating
services, to that of broad groups of comparable mutual funds or to that of
unmanaged indices that may assume investment of dividends but do not reflect
deductions for administrative and management costs. Further, the performance of
each class of a Fund may be compared to other funds or to relevant indices that
may calculate total return without reflecting sales charges; in which case, a
Fund may advertise its total return in the same manner. If reflected, sales
charges would reduce these total return calculations.

         The Money Market and Institutional Money Market Funds may quote actual
total return performance in advertising and other types of literature compared
to indices or averages of alternative financial products available to
prospective investors. The performance comparisons may include the average
return of various bank instruments, some of which may carry certain return
guarantees offered by leading banks and thrifts, as monitored by the BANK RATE
MONITOR, and those of corporate and government security price indices of various
durations prepared by Shearson Lehman Brothers, Salomon Brothers, Inc. and the
IBC/Donoghue organization. These indices are not managed for any investment
goals.

         The Money Market and Institutional Money Market Funds may also use
comparative performance information computed by and available from certain
industry and general market research and publications, such as Lipper Analytical
Services, Inc.

         Statistical and performance information compiled and maintained by CDA
Technologies, Inc. and Interactive Data Corporation may also be used. CDA is a
performance evaluation service that maintains a statistical data base of
performance, as reported by a diverse universe of independently-managed mutual
funds. Interactive Data Corporation is a statistical access service that
maintains a data base of various industry indicators, such as historical and
current price/earning information and individual stock and fixed income price
and return information.

         Current interest rate and yield information on government debt
obligations of various durations, as reported weekly by the Federal Reserve
(Bulletin H. 15), may also be used. Also current rate information on municipal
debt obligations of various durations, as reported daily by the Bond Buyer, may
also be used. The BOND BUYER is published daily and is an industry-accepted
source for current municipal bond market information.

         Comparative information on the Consumer Price Index may also be
included. This Index, as prepared by the U.S. Bureau of Labor Statistics, is the
most commonly used measure of inflation. It indicates the cost fluctuations of a
representative group of consumer goods. It does not represent a return on
investment.

         THE EQUITY, BOND AND MUNICIPAL BOND FUNDS AND THE FUNDS OF FUNDS may
quote actual total return performance from time to time in advertising and other
types of literature compared to results reported by the Dow Jones Industrial
Average.

         The Dow Jones Industrial Average is an industry-accepted unmanaged
index of generally conservative securities used for measuring general market
performance. The performance reported will reflect the reinvestment of all
distributions on a quarterly basis and market price fluctuations. The index does
not take into account any brokerage commissions or other fees. Comparative
information on the Consumer Price Index may also be included.

         The Equity Funds, the Bond Funds, the Municipal Bond Funds and the
Funds of Funds may also promote the yield and/or total return performance and
use comparative performance information computed by and available from certain
industry and general market research and publications, such as Lipper Analytical
Services, Inc.; they may also use indices such as the Standard & Poor's 400
Composite Stock Index, the Standard & Poor's 500 Composite Stock Index, the
Standard & Poor's 600 Composite Stock Index, the Russell 2000, or the Morgan
Stanley International European, Asian and Far East Gross Domestic Product Index
for performance comparison. Statistical and performance information compiled and
maintained by CDA Technologies, Inc. and Interactive Data Corporation may also
be used.

         THE BOND FUNDS, THE FUNDS OF FUNDS AND THE ASSET ALLOCATION FUND may
quote actual yield and/or total return performance in advertising and other
types of literature compared to indices or averages of alternative financial
products available to prospective investors. The performance comparisons may
include the average return of various bank instruments, some of which may carry
certain return guarantees offered by leading banks and thrifts as monitored by
BANK RATE MONITOR, and those of corporate bond and government security price
indices of various durations. Comparative information on the Consumer Price
Index may also be included.

Technologies, Inc. and Interactive Data Corporation.

            The Bond Funds, the Funds of Funds and the Asset Allocation Fund may

MISCELLANEOUS

            The Trust is not required to hold a meeting of Shareholders for the
purpose of electing Trustees except that (i) the Trust is required to hold a
Shareholders' meeting for the election of Trustees at such time as less than a
majority of the Trustees holding office have been elected by Shareholders and
(ii) if, as a result of a vacancy on the Board of Trustees, less than two-thirds
of the Trustees holding office have been elected by the Shareholders, that
vacancy may only be filled by a vote of the Shareholders. In addition, Trustees
may be removed from office by a written consent signed by the holders of Shares
representing two-thirds of the outstanding Shares of the Trust at a meeting duly
called for the purpose, which meeting shall be held upon the written request of
the holders of Shares representing not less than 20% of the outstanding Shares
of the Trust. Except as set forth above, the Trustees may continue to hold
office and may appoint successor Trustees.

            As used in the Trust's Prospectuses and in this Statement of
Additional Information, "assets belonging to a Fund" means the consideration
received by the Trust upon the issuance or sale of Shares in that Fund, together
with all income, earnings, profits, and proceeds derived from the investment
thereof, including any proceeds from the sale, exchange, or liquidation of such
investments, and any funds or payments derived from any reinvestment of such
proceeds, and any general assets of the Trust not readily identified as
belonging to a particular Fund that are allocated to that Fund by the Trust's
Board of Trustees. The Board of Trustees may allocate such general assets in any
manner it deems fair and equitable. It is anticipated that the factor that will
be used by the Board of Trustees in making allocations of general assets to
particular Funds will be the relative net asset values of the respective Funds
at the time of allocation. Assets belonging to a particular Fund are charged
with the direct liabilities and expenses in respect of that Fund, and with a
share of the general liabilities and expenses of the Trust not readily
identified as belonging to a particular Fund that are allocated to that Fund in
proportion to the relative net asset values of the respective Funds at the time
of allocation. The timing of allocations of general assets and general
liabilities and expenses of the Trust to particular Funds will be determined by
the Board of Trustees of the Trust and will be in accordance with generally
accepted accounting principles. Determinations by the Board of Trustees of the
Trust as to the timing of the allocation of general liabilities and expenses and
as to the timing and allocable portion of any general assets with respect to a
particular Fund are conclusive. For information regarding the allocations of
Class Expenses to particular classes of a Fund, see the respective Prospectus of
the Fund under "MANAGEMENT-Expenses."

            As used in the Trust's Prospectuses and in this Statement of
Additional Information, a "vote of a majority of the outstanding Shares" of the
Trust, a particular Fund, or a particular class of Shares of a Fund, means the
affirmative vote of the lesser of (a) more than 50% of the outstanding Shares of
the Trust, such Fund, or such class of Shares of such Fund, or (b) 67% or more
of the Shares of the Trust, such Fund, or such class of Shares of such Fund
present at a meeting at which the holders of more than 50% of the outstanding
Shares of the Trust, such Fund, or such class of Shares of such Fund are
represented in person or by proxy.

            The Trust is registered with the Securities and Exchange Commission
as a management investment company. Such registration does not involve
supervision by the Commission of the management or policies of the Trust.

            The Prospectus and this Statement of Additional Information omit
certain of the information contained in the Registration Statement filed with
the Securities and Exchange Commission. Copies of such information may be
obtained from the Commission upon payment of the prescribed fee.

            The Prospectus and this Statement of Additional Information are not
an offering of the securities herein described in any State in which such
offering may not lawfully be made. No salesman, dealer, or other person is
authorized to give any information or make any representation other than those
contained in the Prospectus and Statement of Additional Information.

NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 1997
 
1. ORGANIZATION:
 
   The One Group (the "Trust") is registered under the Investment Company Act of
   1940, as amended (the "1940 Act"), as an open-end investment company
   established as a Massachusetts business trust. The accompanying financial
   statements and financial highlights are those of the Asset Allocation Fund,
   the Income Equity Fund, the Equity Index Fund, the Value Growth Fund, the
   Large Company Value Fund, the Disciplined Value Fund, the Large Company
   Growth Fund, the Growth Opportunities Fund, the Gulf South Growth Fund and
   the International Equity Index Fund (individually a "Fund", collectively the
   "Funds") only. Subsequent to June 30, 1997, the investment objective of the
   Gulf South Growth Fund was changed to permit investments in companies
   headquartered or doing business outside of the Southeastern region of the
   United States, and to focus the Fund's investments to a greater extent on
   investments in the equity securities of small capitalization and emerging
   growth companies. As a result, the name of the Fund was changed to the One
   Group Small Capitalization Fund. The Funds are each offered in Fiduciary
   Class, Class A and Class B Shares. Class A Shares are subject to initial
   sales charges, imposed at the time of purchase, in accordance with the Funds'
   prospectuses. Certain redemptions of Class B Shares are subject to contingent
   deferred sales charges in accordance with the Funds' prospectuses. Each Fund
   is a diversified mutual fund except the Gulf South Growth Fund which is
   non-diversified.
 
   The Trust entered into an Agreement and Plan of Reorganization (the
   "Agreement") with the Paragon Portfolio ("Paragon"), a Massachusetts business
   trust. Pursuant to the Agreement, all of the assets and liabilities of each
   Paragon Fund transferred to a Fund of The One Group in exchange for shares of
   the corresponding Fund of The One Group. Subsequent to the reorganization,
   the fiscal period end changed from November 30 to June 30 for the Value
   Growth Fund and the Gulf South Growth Fund. Therefore, the prior period
   statement of changes in net assets and financial highlights for those Funds
   present the results for the seven months ended June 30, 1996.
 
   The Funds' investment objectives are as follows:

2. SIGNIFICANT ACCOUNTING POLICIES:
 
   The following is a summary of significant accounting policies followed by the
   Trust in preparation of its financial statements. The policies are in
   conformity with generally accepted accounting principles. The preparation of
   financial statements requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of income and expenses for the
   period. Actual results could differ from those estimates.
 
       SECURITY VALUATION
 
       Listed securities are valued at the last sales price on the principal
       exchange where such securities are traded. Unlisted securities or listed
       securities for which last sales prices are not available are valued at
       the mean of the latest bid and asked price in the principal market where
       such securities are traded. Corporate debt securities and debt securities
       of U.S. issuers (other than short-term investments maturing in 60 days or
       less), including municipal securities, are valued on the basis of
       valuations provided by dealers or by an independent pricing service
       approved by the Board of Trustees. Short-term investments maturing in 60
       days or less are valued at amortized cost, which approximates market
       value. Futures contracts are valued at the settlement price established
       each day by the board of trade or exchange on which they are traded.
       Options traded on an exchange are valued using the last sale price or, in
       the absence of a sale, the last offering price. Options traded
       over-the-counter are valued using dealer-supplied valuations. Investments
       for which there are no such quotations or valuations are carried at fair
       value as determined by the Banc One Investment Advisors Corporation (the
       "Advisor") under the direction of the Board of Trustees.
 
       FOREIGN CURRENCY TRANSLATION
 
       Investment valuations, other assets and liabilities initially expressed
       in foreign currencies are converted each business day into U.S. dollars
       based upon current exchange rates. Purchases and sales of foreign
       investments and income and expenses are converted into U.S. dollars based
       upon exchange rates prevailing on the respective dates of such
       transactions. That portion of realized gains or losses and unrealized
       appreciation or depreciation from investments due to fluctuations in
       foreign currency exchange rates is not separately disclosed. Such
       fluctuations are included with the net realized and unrealized gain or
       loss from investments.
 
       FORWARD FOREIGN CURRENCY CONTRACTS
 
       Forward foreign currency contracts are valued at the daily exchange rate
       of the underlying currency. Purchases and sales of forward foreign
       currency contracts having the same settlement date and broker are
       presented net on the Statement of Assets and Liabilities. The forward
       foreign currency exchange contracts are adjusted by the daily exchange
       rate of the underlying currency and any gains or losses are recorded for
       financial statement purposes as unrealized appreciation or depreciation
       until the contract settlement date. Gains or

   losses from the purchase or sale of forward foreign currency contracts having
   the same settlement date and broker are recorded as realized on the date of
   offset; otherwise gains or losses are recorded as realized on settlement
   date.
 
   REPURCHASE AGREEMENTS
 
   The Funds may invest in repurchase agreements with institutions that the
   investment advisor has determined are creditworthy. Each repurchase agreement
   is recorded at cost. The Fund requires that the securities purchased in a
   repurchase agreement transaction be transferred to the custodian in a manner
   sufficient to enable the Fund to obtain those securities in the event of a
   counterparty default. The seller, under the repurchase agreement, is required
   to maintain the value of the securities held at not less than the repurchase
   price, including accrued interest. Repurchase agreements are considered to be
   loans under the 1940 Act.
 
   WRITTEN OPTIONS
 
   The Funds may write covered call or put options for which premiums received
   are recorded as liabilities and are subsequently adjusted to the current
   value of the options written. Premiums received from writing options which
   expire are treated as realized gains. Premiums received from writing options,
   which are either exercised or closed, are offset against the proceeds
   received or amount paid on the transaction to determine realized gains or
   losses.
 
   FUTURES CONTRACTS
 
   The Funds may enter into futures contracts for the delayed delivery of
   securities at a fixed price at some future date or for the change in the
   value of a specified financial index over a predetermined time period. Cash
   or securities are deposited with brokers in order to maintain a position.
   Subsequent payments made or received by the Fund based on the daily change in
   the market value of the position are recorded as unrealized appreciation or
   depreciation until the contract is closed out, at which time the appreciation
   or depreciation is realized.
 
   INDEXED SECURITIES
 
   The 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 reference instruments. Indexed securities may
   be more volatile than the referenced instrument itself, but any loss is
   limited to the amount of the original investment.
 
   SECURITIES LENDING
 
   To generate additional income, the Funds may lend up to 33% of securities
   in which they are invested pursuant to agreements requiring that the loan be
   continuously secured by cash, U.S. Government or U.S. Government Agency
   securities, shares of an investment trust or mutual fund, or any combination
   of cash and such securities as collateral equal at all times to at least 100%
   of the market value plus accrued interest on the securities lent. The Funds
   continue to earn dividends and interest on securities lent while
   simultaneously seeking to earn interest on the investment of collateral.
   Collateral is marked to market daily to provide a level of collateral at
   least equal to the market value of securities lent. There may be risks of
   delay in recovery of the securities or even loss of rights in the collateral
   should the borrower of the securities fail financially. However, loans will
   be made only to borrowers deemed by the Advisor to be of good standing and
   creditworthy under guidelines established by the Board of Trustees and when,
   in the judgment of the Advisor, the consideration which can be earned
   currently from such securities loans justifies the attendant risk. Loans are
   subject to termination by the

</TABLE>
 
       The loaned securities were fully collateralized by U.S. Government
       securities as of June 30, 1997.
 
       SECURITY TRANSACTIONS AND RELATED INCOME
 
       Security transactions are accounted for on a trade date basis. Net
       realized gains or losses from sales of securities are determined on the
       specific identification cost method. Interest income and expenses are
       recognized on the accrual basis. Dividends are recorded on the
       ex-dividend date. Interest income, including any discount or premium, is
       accrued as earned using the effective interest method.
 
       EXPENSES
 
       Expenses directly attributable to a Fund are charged directly to that
       Fund, while the expenses which are attributable to more than one Fund of
       the Trust are allocated among the respective Funds. Each class of shares
       bears its pro-rata portion of expenses attributable to its series, except
       that each class separately bears expenses related specifically to that
       class, such as distribution fees.
 
       DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
 
       Distributions from net investment income and from net capital gains are
       determined in accordance with income tax regulations which may differ
       from generally accepted accounting principles. These differences are
       primarily due to differing treatments for expiring capital loss
       carryforwards, foreign currency transactions, and deferrals of certain
       losses. Permanent book and tax basis differences have been reclassified
       among the components of net assets.
 
       FEDERAL INCOME TAXES
 
       The Trust treats each Fund as a separate entity for Federal income tax
       purposes. Each Fund intends to continue to qualify as a regulated
       investment company by complying with the provisions available to certain
       investment companies as defined in applicable sections of the Internal
       Revenue Code, and to make distributions from net investment income and
       from net realized capital gains sufficient to relieve it from all, or
       substantially all, Federal income taxes. Withholding taxes on foreign
       dividends have been paid or provided for in accordance with the
       applicable country's tax rules and rates.

3. SHARES OF BENEFICIAL INTEREST:
 
   The Trust has an unlimited number of shares of beneficial interest, with no
   par value which may, without shareholder approval, be divided into an
   unlimited number of series of such shares and any series may be classified or
   reclassified into one or more. The Trust is registered to offer forty series
   and five classes of shares: Fiduciary, Class A, Class B, Class C and Service.
   Currently, the Trust consists of thirty three active funds and, not all funds
   can offer all classes of shares. As of June 30, 1997, there were no
   shareholders in the Class C or the Service Class of the Funds. Shareholders
   are entitled to one vote for each full share held and will vote in the
   aggregate and not by class or series, except as otherwise expressly required
   by law or when the Board of Trustees has determined that the matter to be
   voted on affects only the interest of shareholders of a particular class or
   series. The following is a summary of transactions in Fund shares for the
   periods ended June 30, 1997 and June 30, 1996:

4. INVESTMENT ADVISORY, ADMINISTRATIVE, AND DISTRIBUTION AGREEMENTS:
 
   The Trust and the Advisor are parties to an investment advisory agreement
   under which the Advisor is entitled to a fee, computed daily and paid
   monthly, at the annual rate of 0.74% of the average net assets of the Income
   Equity Fund, the Value Growth Fund, the Large Company Value Fund, the
   Disciplined Value Fund, the Large Company Growth Fund, the Growth
   Opportunities Fund, and the Gulf South Growth Fund; 0.65% of the average
   daily net assets of the Asset Allocation Fund; 0.55% of the average daily net
   assets of the International Equity Index Fund; and 0.30% of the average daily
   net assets of the Equity Index Fund.
 
   The Trust and The One Group Services Company (the "Administrator"), a
   wholly-owned subsidiary of The BISYS Group, Inc., are parties to an
   administrative agreement under which the Administrator provides services for
   a fee that is computed daily and paid monthly, at an annual rate of 0.20% on
   the first $1.5 billion of Trust net assets (excluding the Investor Growth
   Fund, the Investor Growth & Income Fund, the Investor Conservative Fund, and
   the Investor Balanced Fund (the "Investor Funds") and the Treasury Only Money
   Market Fund and the Government 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 the Investor Funds and the
   Institutional Money Market Funds) over $2 billion. The Advisor also serves as
   Sub-Administrator to each Fund of the Trust, pursuant to an agreement between
   the Administrator and the Advisor. Pursuant to this agreement, the Advisor
   performs many of the Administrator's duties, for which the Advisor receives a
   fee paid by the Administrator.
 
   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 and Class B Shares are subject to distribution and
   shareholder services plans (the "Plans") pursuant to Rule 12b-1 under the
   1940 Act. As provided in the Plans, the Trust will pay the Distributor a fee
   of 0.35% of the average daily net assets of Class A Shares of each of the
   Funds and 1.00% of the average daily net assets of the Class B Shares of each
   of the Funds. Currently, the Distributor has voluntarily agreed to limit
   payments under the Plans to 0.25% of average daily net assets of the Class A
   Shares of each Fund. Up to 0.25% of the fees payable under the Plans may be
   used as compensation for shareholder services by the Distributor and/or
   financial institutions and intermediaries. Fees paid under the Plans may be
   applied by the Distributor toward (i) compensation for its services in
   connection with distribution assistance or provision of shareholder services;
   or (ii) payments to financial institutions and intermediaries such as banks
   (including affiliates of the Adviser), 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. Fiduciary
   Class Shares of each Fund are offered without distribution fees. For the year
   ended June 30, 1997, the Distributor received $14,356,900 from commissions
   earned on sales of Class A Shares and redemptions of Class B Shares, of
   which, the Distributor re-allowed $14,210,374 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.

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

   The Trust entered an Agreement and Plan of Reorganization ("Reorganization")
   with Paragon pursuant to which all of the assets and liabilities of each
   Paragon Fund transferred to a Fund of The One Group in exchange for shares of

   transferred its assets and liabilities to the Income Equity Fund. The Paragon
   Value Growth Fund and the Paragon Gulf South Growth Fund transferred its
   assets and liabilities to the Value Growth Fund and Gulf South Growth Fund,

   Federal income tax purposes, was completed on March 25, 1996 following
   approval by shareholders of Paragon at a special shareholder meeting. The
   following is a summary of shares outstanding, net assets, net asset value per

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1997
 
To the Shareholders and Board of Trustees of
  The One Group Family of Mutual Funds:
 
We have audited the accompanying statements of assets and liabilities of the
Asset Allocation Fund, the Income Equity Fund, the Equity Index Fund, the Value
Growth Fund, the Large Company Value Fund, the Disciplined Value Fund, the Large
Company Growth Fund, the Growth Opportunities Fund, the Gulf South Growth Fund
and the International Equity Index Fund (ten series of The One Group Family of
Mutual Funds), including the schedules of portfolio investments, as of June 30,
1997, and the related statements of operations, statements of changes in net
assets and the financial highlights for each period presented except as noted in
the next paragraph. These financial statements and financial highlights are the
responsibility of The One Group Family of Mutual Funds' management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.
 
The Large Company Growth Fund's financial highlights for the year ended June 30,
1993 were audited by other auditors, whose report dated August 25, 1993
expressed an unqualified opinion on the financial highlights. The Value Growth
Fund's statement of changes in net asset for the year ended November 30, 1995
and the financial highlights for each of the four years in the period ended
November 30, 1995 were audited by other auditors, whose report dated January 19,
1996 expressed an unqualified opinion on those financial statements and
financial highlights. The Gulf South Growth Fund's statement of changes in net
assets for the year ended November 30, 1995 and the financial highlights for
each of the four years in the period ended November 30, 1995 were audited by
other auditors, whose report dated January 19, 1996 expressed an unqualified
opinion on those financial statements and financial highlights.
 
We conducted our audits in accordance with generally accepted auditing
standards. 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. Our procedures included
confirmation of securities owned as of June 30, 1997 by correspondence with the
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above, except as noted in the second paragraph present fairly, in all material
respects, the financial position of the Asset Allocation Fund, the Income Equity
Fund, the Equity Index Fund, the Value Growth Fund, the Large Company Value
Fund, the Disciplined Value Fund, the Large Company Growth Fund, the Growth
Opportunities Fund, the Gulf South Growth Fund and the International Equity
Index Fund as of June 30, 1997, the results of their operations, the changes in
their net assets and the financial highlights for the periods indicated herein,
in conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS                                       JUNE 30,1997
 
1. ORGANIZATION:
 
   The One Group (the "Trust") is registered under the Investment Company Act of
   1940, as amended (the "1940 Act"), as an open-end investment company
   established as a Massachusetts business trust. The accompanying financial
   statements and financial highlights are those of the Ultra Short-Term Income
   Fund (previously named the Government ARM Fund), the Limited Volatility Bond
   Fund, the Intermediate Bond Fund, the Government Bond Fund, the Income Bond
   Fund , and the Treasury & Agency Fund (individually a "Fund", collectively
   the "Funds") only. The Funds are each offered in Fiduciary Class, Class A and
   Class B Shares. Class A Shares are subject to initial sales charges, imposed
   at the time of purchase, in accordance with the Funds' prospectuses. Certain
   redemptions of Class B Shares are subject to contingent deferred sales
   charges in accordance with the Funds' prospectuses. Each Fund is a
   diversified mutual fund.
 
   The Trust entered into an Agreement and Plan of Reorganization (the
   "Agreement") with the Paragon Portfolio ("Paragon"), a Massachusetts business
   trust. Pursuant to the Agreement all of the assets and liabilities of each
   Paragon Fund transferred to a fund of The One Group in exchange for shares of
   the corresponding fund of The One Group. The statements of changes in net
   assets and financial highlights for periods prior to the reorganization,
   March 25, 1996, are presented for funds of The One Group only.
 
   The Funds investment objectives are as follows:

   FUND                              OBJECTIVE
   -----------------------------     -----------------------------------------------------------------
   <S>                               <C>
   Ultra Short-Term Income Fund      A high level of current income consistent with low volatility of
                                      principal by investing in a diversified portfolio of short-term
                                      investment grade securities.
 
   Limited Volatility Bond Fund      Current income consistent with the preservation of capital
                                      through investment in high and medium-grade fixed-income
                                      securities.
 
   Intermediate Bond Fund            Current income consistent with the preservation of capital by
                                      investing in high and medium-grade fixed-income securities with
                                      intermediate maturities.
 
   Government Bond Fund              A high level of current income with liquidity and safety of
                                      principal.
 
   Income Bond Fund                  A high level of current income by investing primarily in a
                                      diversified portfolio of high, medium and low grade debt
                                      securities.
 
   Treasury & Agency Fund            A high level of current income by investing in U.S. Treasury and
                                      other U.S. Agency obligations with a primary, but not exclusive,
                                      focus on issues that produce income exempt from state income
                                      taxes.

2. SIGNIFICANT ACCOUNTING POLICIES:
 
   The following is a summary of significant accounting policies followed by the
   Trust in preparation of its financial statements. The policies are in
   conformity with generally accepted accounting principles. The preparation of
   financial statements requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of income and expenses for the
   period. Actual results could differ from those estimates.
 
       SECURITY VALUATION
 
       Corporate debt securities and debt securities of U.S. issuers (other than
       short-term investments maturing in 60 days or less), including municipal
       securities, are valued on the basis of valuations provided by dealers or
       by

                                                                              37

NOTES TO FINANCIAL STATEMENTS, CONTINUED                            JUNE 30,1997
 
       an independent pricing service approved by the Board of Trustees.
       Short-term investments maturing in 60 days or less are valued at
       amortized cost, which approximates market value. Futures contracts are
       valued at the settlement price established each day by the board of trade
       or an exchange on which they are traded. Options traded on an exchange
       are valued using the last sale price or, in the absence of a sale, the
       last offering price. Options traded over-the-counter are valued using
       dealer-supplied valuations. Investments for which there are no such
       quotations or valuations are valued at fair value as determined in good
       faith by the Adviser under the direction of the Board of Trustees.
 
       REPURCHASE AGREEMENTS
 
       The Funds may invest in repurchase agreements with institutions that Banc
       One Investment Advisors Corporation (the "Advisor") has determined are
       creditworthy. Each repurchase agreement is recorded at cost. The Fund
       requires that the securities purchased in a repurchase agreement
       transaction be transferred to the custodian in a manner sufficient to
       enable the Fund to obtain those securities in the event of a counterparty
       default. The seller, under the repurchase agreement, is required to
       maintain the value of the securities held at not less than the repurchase
       price, including accrued interest. Repurchase agreements are considered
       to be loans by a fund under the 1940 Act.
 
       WRITTEN OPTIONS
 
       The Funds may write covered call or put options for which premiums
       received are recorded as liabilities and are subsequently adjusted to the
       current value of the options written. Premiums received from writing
       options which expire are treated as realized gains. Premiums received
       from writing options, which are either exercised or closed, are offset
       against the proceeds received or amount paid on the transaction to
       determine realized gains or losses.
 
       FUTURES CONTRACTS
 
       The Funds may enter into futures contracts for the delayed delivery of
       securities at a fixed price at some future date or for the change in the
       value of a specified financial index over a predetermined time period.
       Cash or securities are deposited with brokers in order to maintain a
       position. Subsequent payments made or received by the fund based on the
       daily change in the market value of the position are recorded as
       unrealized appreciation or depreciation until the contract is closed out,
       at which time the appreciation or depreciation is realized.
 
       INDEXED SECURITIES
 
       The 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 reference instruments. Indexed securities
       may be more volatile than the referenced instrument itself, but any loss
       is limited to the amount of the original investment.
 
       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% of securities in
   which they are invested pursuant to agreements requiring that the loan be
   continuously secured by cash, U.S. Government or U.S. Government Agency
   securities, shares of an investment trust or mutual fund, or any combination
   of cash and such securities as collateral equal at all times to at least 100%
   of the market value plus accrued interest on the securities lent. The Funds
   continue to earn interest on securities lent while simultaneously seeking to
   earn interest on the investment of 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 risk. 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, 1997, the following Funds had securities
   with the following market values on loan (amounts in thousands):

SECURITY TRANSACTIONS AND RELATED INCOME
 
Security transactions are accounted for on a trade date basis. Net realized
gains or losses from sales of securities are determined on the specific
identification cost method. Interest income and expenses are recognized on the
accrual basis. Dividends are recorded on the ex-dividend date. Interest income,
including any discount or premium, is accrued as earned using the effective
interest method.
 
EXPENSES
 
Expenses directly attributable to a Fund are charged directly to that Fund,
while the expenses which are attributable to more than one fund of the Trust are
allocated among the respective Funds. Each class of shares bears its pro-rata
portion of expenses attributable to its series, except that each class
separately bears expenses related specifically to that class, such as
distribution fees.
 
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
 
Dividends from net investment income are declared daily and paid monthly for the
Funds. Net realized capital gains, if any, are distributed at least annually.
Dividends are declared separately for each class. No class has preferential
dividend rights; differences in per share dividend rates are generally due to
differences in separate class expenses.
 
Distributions from net investment income and from net capital gains are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. These differences are primarily due to

differing treatments for mortgage-backed securities, expiring capital loss
carryforwards, and deferrals of certain losses. Permanent book and tax basis
differences have been reclassified among the components of net assets.
 
ORGANIZATION COSTS
 
Costs incurred by the Trust in connection with its organization, including the
fees and expenses of registering and qualifying its shares for distribution have
been deferred and are being amortized using the straight-line method over a
period of five years beginning with the commencement of each Fund's operations.
All such costs, which are attributable to more than one fund of the Trust, have
been allocated among the respective funds pro-rata, based on the relative net
assets of each Fund. In the event that any of the initial shares are redeemed
during such period by any holder thereof, the related fund will be reimbursed by
such holder for any unamortized organization costs in the proportion as the
number of initial shares being redeemed bears to the number of initial shares
outstanding at the time of redemption.
 
FEDERAL INCOME TAXES
 
The Trust treats each Fund as a separate entity for Federal income tax purposes.
Each Fund intends to continue to qualify as a regulated investment company by
complying with the provisions available to certain investment companies as
defined in applicable sections of the Internal Revenue Code, and to make
distributions from net investment income and from net realized capital gains
sufficient to relieve it from all, or substantially all, Federal income taxes.
 
3. SHARES OF BENEFICIAL INTEREST:
 
   The Trust has an unlimited number of shares of beneficial interest, with no
   par value, which may, without shareholder approval, be divided into an
   unlimited number of series of such shares and any series may be classified or
   reclassified into one or more classes. The Trust is registered to offer forty
   series and five classes of shares: Fiduciary, Class A, Class B, Class C and
   Service. Currently, the Trust consists of thirty three active funds and not
   all funds can offer all classes of shares. As of June 30, 1997, no
   shareholders were in Class C or the Service Class of the Funds. Shareholders
   are entitled to one vote for each full share held and will vote in the
   aggregate and not by class or series, except as otherwise expressly required
   by law or when the Board of Trustees has determined that the matter to be
   voted on affects only the interest of shareholders of a particular class or
   series. The following is a summary of transactions in Fund shares for the
   fiscal years ending June 30, 1997 and 1996:

4. INVESTMENT ADVISORY, ADMINISTRATIVE, 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
   net assets: 0.60% of the Income Bond Fund, the Intermediate Bond Fund and the
   Limited Volatility Bond Fund; 0.55% of the Ultra Short-Term Income Fund;
   0.45% of the Government Bond Fund; and 0.40% of the Treasury & Agency Fund.
 
   The Trust and The One Group Services Company (the "Administrator"), a
   wholly-owned subsidiary of The BISYS Group, Inc., are parties to an
   administrative agreement under which the Administrator provides services for
   a fee that is computed daily and paid monthly, at an annual rate of 0.20% on
   the first $1.5 billion of Trust net 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 and the Government 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. The Advisor also serves as
   Sub-Administrator to each fund of the Trust, pursuant to an agreement between
   the Administrator and the Advisor. Pursuant to this agreement, the Advisor
   performs many of the Administrator's duties, for which the Advisor receives a
   fee paid by the Administrator.
 
   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 and Class B Shares are subject to a distribution
   and shareholder services plan (the "Plans") pursuant to Rule 12b-1 under the
   1940 Act. As provided in the Plans, the Trust will pay the Distributor a fee
   of 0.35% of the average daily net assets of Class A Shares of each of the
   Funds and 1.00% of the average daily net assets of the Class B Shares 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 Ultra Short-Term Income Fund, Limited Volatility Bond Fund and Treasury &
   Agency Fund and 0.90% of average daily net assets of Intermediate Bond Fund,
   Government Bond Fund and Income 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 Adviser), 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. Fiduciary Class Shares of each Fund are offered without
   distribution fees. For the period ended June 30, 1997, the Distributor
   received $952,230 from commissions earned on sales of Class A Shares and
   redemptions of Class B Shares, of which the Distributor re-allowed $936,799
   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.

6. FINANCIAL INSTRUMENTS:
 
   Investing in financial instruments such as written options, futures,
   structured notes and indexed securities involves risk in excess of the
   amounts reflected in the Statement 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.
 
7. REORGANIZATIONS:
 
   The Trust entered an Agreement and Plan of Reorganization ("Reorganization")
   with Paragon pursuant to which all of the assets and liabilities of each
   Paragon Fund transferred to a fund of The One Group in exchange for shares of
   the corresponding fund of The One Group. The Paragon Short-Term Government
   Fund and the Paragon Intermediate-Term Bond Fund transferred their assets and
   liabilities to the Limited Volatility Bond Fund and the Government Bond Fund,
   respectively. The Reorganization, which qualified as a tax-free exchange for
   Federal income tax purposes, was completed on March 25, 1996 following
   approval by shareholders of Paragon at a special shareholder meeting. The
   following is a summary of shares outstanding, net assets, net asset value per
   share and unrealized appreciation immediately before and after the
   Reorganization (amounts in thousands except net asset value):

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1997
 
To the Shareholders and Board of Trustees of
  The One Group Family of Mutual Funds:
 
We have audited the accompanying statements of assets and liabilities of the
Ultra Short-Term Income Fund (formally the Government ARM Fund), the Limited
Volatility Bond Fund, the Intermediate Bond Fund, the Government Bond Fund, the
Income Bond Fund and the Treasury & Agency Fund (six series of The One Group
Family of Mutual Funds), including the schedules of portfolio investments, as of
June 30, 1997, and the related statements of operations, statements of changes
in net assets and the financial highlights for each period presented except as
noted in the next paragraph. These financial statements and financial highlights
are the responsibility of The One Group Family of Mutual Funds' management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.
 
The financial highlights for the year ended June 30, 1993 for the Intermediate
Bond Fund were audited by other auditors whose report dated August 25, 1993
expressed an unqualified opinion on the financial highlights.
 
We conducted our audits in accordance with generally accepted auditing
standards. 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. Our procedures included
confirmation of securities owned as of June 30, 1997 by correspondence with the
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above, except as noted in the second paragraph present fairly, in all material
respects, the financial position of the Ultra Short-Term Income Fund, the
Limited Volatility Bond Fund, the Intermediate Bond Fund, the Government Bond
Fund, the Income Bond Fund and the Treasury & Agency Fund as of June 30, 1997,
the results of their operations, the changes in their net assets and the
financial highlights for the periods indicated herein, in conformity with
generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 1997
 
1. ORGANIZATION:
 
   The One Group (the "Trust") is registered under the Investment Company Act of
   1940, as amended (the "1940 Act"), as an open-end investment company
   established as a Massachusetts business trust. The accompanying financial
   statements and financial highlights are those of the Intermediate Tax-Free
   Bond Fund, the Municipal Income Fund, the Kentucky Municipal Bond Fund, the
   Ohio Municipal Bond Fund, the Louisiana Municipal Bond Fund, the Arizona
   Municipal Bond Fund, and the West Virginia Municipal Bond Fund (individually
   a "Fund", collectively the "Funds") only. The Funds are each offered in
   Fiduciary Class, Class A and Class B Shares. Class A Shares are subject to
   initial sales charges, imposed at the time of purchase, in accordance with
   the Funds' prospectuses. Certain redemptions of Class B Shares are subject to
   contingent deferred sales charges in accordance with the Funds' prospectuses.
   Each Fund is a non-diversified mutual fund, except for the Intermediate
   Tax-Free Bond and the Municipal Income Fund, which are diversified.
 
   The Trust entered into an Agreement and Plan of Reorganization (the
   "Agreement") with the Paragon Portfolio ("Paragon"), a Massachusetts business
   trust. Pursuant to the Agreement all of the assets and liabilities of each
   Paragon Fund transferred to a fund of The One Group in exchange for shares of
   the corresponding fund of The One Group. Subsequent to the reorganization,
   the fiscal period end changed from November 30 to June 30 for the Louisiana
   Municipal Bond Fund. Therefore, the prior period statement of changes in net
   assets for that Fund presents the changes in net assets for the seven months
   ended June 30, 1996.
 
   The Funds' investment objectives are as follows:

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

NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 1997
 
   SECURITY VALUATION
 
   Corporate debt securities and debt securities of U.S. issuers (other than
   short-term investments maturing in 60 days or less), including municipal
   securities, are valued on the basis of valuations provided by dealers or by
   an independent pricing service approved by the Board of Trustees. Short-term
   investments maturing in 60 days or less are valued at amortized cost, which
   approximates market value. Futures contracts are valued at the settlement
   price established each day by the board of trade or an exchange on which they
   are traded. Options traded on an exchange are valued using the last sale
   price or, in the absence of a sale, the last offering price. Options traded
   over-the-counter are valued using dealer-supplied valuations. Investments for
   which there are no such quotations or valuations are valued at fair value as
   determined in good faith by Banc One Investment Advisors Corporation (the
   "Advisor") under the direction of the Board of Trustees.
 
   REPURCHASE AGREEMENTS
 
   The Funds may invest in repurchase agreements with institutions that the
   Fund's investment advisor has determined are creditworthy. Each repurchase
   agreement is recorded at cost. The Fund requires that the securities
   purchased in a repurchase agreement transaction be transferred to the
   custodian in a manner sufficient to enable the Fund to obtain those
   securities in the event of a counterparty default. The seller, under the
   repurchase agreement, is required to maintain the value of the securities
   held at not less than the repurchase price, including accrued interest.
   Repurchase agreements are considered to be loans by a fund under the 1940
   Act.
 
   WRITTEN OPTIONS
 
   The Funds may write covered call or put options for which premiums received
   are recorded as liabilities and are subsequently adjusted to the current
   value of the options written. Premiums received from writing options which
   expire are treated as realized gains. Premiums received from writing options,
   which are either exercised or closed, are offset against the proceeds
   received or amount paid on the transaction to determine realized gains or
   losses.
 
   FUTURES CONTRACTS
 
   The Funds may enter into futures contracts for the delayed delivery of
   securities at a fixed price at some future date or for the change in the
   value of a specified financial index over a predetermined time period. Cash
   or securities are deposited with brokers in order to maintain a position.
   Subsequent payments made or received by the Fund based on the daily change in
   the market value of the position are recorded as unrealized appreciation or
   depreciation until the contract is closed out, at which time the appreciation
   or depreciation is realized.
 
   INDEXED SECURITIES
 
   The 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 reference instruments. Indexed securities may
   be more volatile than the referenced instrument itself, but any loss is
   limited to the amount of the original investment.
 
   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

NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 1997
 
   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% of securities in
   which they are invested pursuant to agreements requiring that the loan be
   continuously secured by cash, U.S. Government or U.S. Government Agency
   securities, shares of an investment trust or mutual fund, or any combination
   of cash and such securities as collateral equal at all times to at least 100%
   of the market value plus accrued interest on the securities lent. The Funds
   continue to earn interest on securities lent while simultaneously seeking to
   earn interest on the investment of 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 judgement of the Advisor, the
   consideration which can be earned currently from such securities loans
   justifies the attendant risk. 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, 1997 the Funds had no securities on
   loan.
 
   SECURITY TRANSACTIONS AND RELATED INCOME
 
   Security transactions are accounted for on a trade date basis. Net realized
   gains or losses from sales of securities are determined on the specific
   identification cost method. Interest income and expenses are recognized on
   the accrual basis. Dividends are recorded on the ex-dividend date. Interest
   income, including any discount or premium, is accrued as earned using the
   effective interest method.
 
   EXPENSES
 
   Expenses directly attributable to a Fund are charged directly to that Fund,
   while the expenses which are attributable to more than one fund of the Trust
   are allocated among the respective Funds. Each class of shares bears its
   pro-rata portion of expenses attributable to its series, except that each
   class separately bears expenses related specifically to that class, such as
   distribution fees.
 
   DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
 
   Dividends from net investment income are declared daily and paid monthly for
   the Funds. Net realized capital gains, if any, are distributed at least
   annually. Dividends are declared separately for each class. No class has
   preferential dividend rights; differences in per share dividend rates are
   generally 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.
 
   FEDERAL INCOME TAXES
 
   The Trust treats each Fund as a separate entity for Federal income tax
   purposes. Each Fund intends to continue to qualify as a regulated 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 forty
   series and five classes of shares: Fiduciary, Class A, Class B, Class C and
   Service. Currently, the Trust consists of thirty three active Funds and not
   all Funds can issue all classes of shares. As of June 30, 1997, there were no
   shareholders in Class C or Service Class of the Funds. Shareholders are
   entitled to one vote for each full share held and will vote in the aggregate
   and not by class or series, except as otherwise expressly required by law or
   when the Board of Trustees has determined that the matter to be voted on
   affects only the interest of shareholders of a particular class or series.
   The following is a summary of transactions in Fund shares for the periods

4. INVESTMENT ADVISORY, ADMINISTRATIVE, 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
   net assets: 0.60% of the Intermediate Tax-Free Bond Fund, the Ohio Municipal
   Bond Fund and the Louisiana Municipal Bond Fund; and 0.45% of the Municipal
   Income Fund, the Kentucky Municipal Bond Fund, the Arizona Municipal Bond
   Fund and the West Virginia Municipal Bond Fund.
 
   The Trust and The One Group Services Company (the "Administrator"), a
   wholly-owned subsidiary of The BISYS Group, Inc., are parties to an
   administrative agreement under which the Administrator provides services for
   a fee that is computed daily and paid monthly, at an annual rate of 0.20% on
   the first $1.5 billion of Trust net assets (excluding the Investor Growth
   Fund, the Investor Growth & Income Fund, the Investor Conservative Fund , and
   the Investor Balanced Fund, the "Investor Funds" and the Treasury Only Money
   Market Fund and the Government 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. The Advisor also serves as Sub-Administrator
   to each fund of the Trust, pursuant to an agreement between the Administrator
   and the Advisor. Pursuant to this agreement, the Advisor performs many of the
   Administrator's duties, for which the Advisor receives a fee paid by the
   Administrator.
 
   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 and Class B Shares are subject to distribution and
   shareholder services plans (the "Plans") pursuant to Rule 12b-1 under the
   1940 Act. As provided in the Plans, the Trust will pay the Distributor a fee
   of 0.35% of the average daily net assets of Class A Shares of each of the
   Funds and 1.00% of the average daily net assets of the Class B Shares of each
   of the Funds. Currently, the Distributor has voluntarily agreed to limit
   payments under the Plans to 0.25% and 0.90% of average daily net assets of
   the Class A Shares and Class B Shares, respectively, of each Fund. Up to
   0.25% of the fees payable under the Plans may be used as compensation for
   shareholder services by the Distributor and/or financial institutions and
   intermediaries. Fees paid under the Plans may be applied by the Distributor
   toward (i) compensation for its services in connection with distribution
   assistance or provision of shareholder services; or (ii) payments to
   financial institutions and intermediaries such as banks (including affiliates
   of the Advisor), brokers, dealers and other institutions, including the
   Distributor's affiliates and subsidiaries as compensation for services or
   reimbursement of expenses incurred in connection with distribution assistance
   or provision of shareholder services. Fiduciary Class Shares of each Fund are
   offered without distribution fees. For the period ended June 30, 1997, the
   Distributor received $1,156,585 from commissions earned on sales of Class A
   Shares and redemptions of Class B Shares, of which the Distributor reallowed
   $1,140,301 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.

6. FINANCIAL INSTRUMENTS:
 
   Investing in financial instruments such as written options, futures,
   structured notes and indexed securities involves risk in excess of the
   amounts reflected in the Statement 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 fluctuation in
   securities.
 
7. CONCENTRATION OF CREDIT RISK:
 
   The Kentucky, Ohio, Louisiana, Arizona and West Virginia Municipal Bond Funds
   invest in primarily debt obligations issued by the respective States and
   their political subdivisions, agencies and public authorities to obtain funds
   for various public purposes. The Funds are more susceptible to economic and
   political factors adversely affecting issuers of the state's specific
   municipal securities than are municipal bond funds that are not concentrated
   in these issuers to the same extent.

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1997
 
To the Shareholders and Board of Trustees of
  The One Group Family of Mutual Funds:
 
We have audited the accompanying statements of assets and liabilities of the
Intermediate Tax-Free Bond Fund, the Municipal Income Fund , the Kentucky
Municipal Bond Fund, the Ohio Municipal Bond Fund, the Louisiana Municipal Bond
Fund, the West Virginia Municipal Bond Fund and the Arizona Municipal Bond Fund
(seven series of The One Group Family of Mutual Funds), including the schedules
of portfolio investments, as of June 30, 1997, and the related statements of
operations, statements of changes in net assets and the financial highlights for
each period presented except as noted in the next paragraph. These financial
statements and financial highlights are the responsibility of The One Group
Family of Mutual Funds' management. Our responsibility is to express an opinion
on these financial statements and the financial highlights based on our audits.
 
The Kentucky Municipal Bond Fund's financial highlights for the period from
February 1, 1994 to January 19, 1995 and the period from March 12, 1993
(commencement of operations) to January 31, 1994 were audited by other auditors
whose report dated April 6, 1995 expressed an unqualified opinion on those
financial statements and financial highlights. The Louisiana Municipal Bond
Fund's statement of changes in net assets for the year ended November 30, 1995
and the financial highlights for each of the four years in the period ended
November 30, 1995 were audited by other auditors, whose report dated January 19,
1996 expressed an unqualified opinion on those financial statements and
financial highlights.
 
We conducted our audits in accordance with generally accepted auditing
standards. 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. Our procedures included
confirmation of securities owned as of June 30, 1997 by correspondence with the
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above, except as noted in the second paragraph present fairly, in all material
respects, the financial position of the Intermediate Tax-Free Bond Fund, the
Municipal Income Fund, the Kentucky Municipal Bond Fund, the Ohio Municipal Bond
Fund, the Louisiana Municipal Bond Fund, the West Virginia Municipal Bond Fund
and the Arizona Municipal Bond Fund as of June 30, 1997, the results of their
operations, the changes in their net assets and the financial highlights for the
periods indicated herein, in conformity with generally accepted accounting
principles.

NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 1997
 
1. ORGANIZATION:
 
   The One Group (the "Trust") is registered under the Investment Company Act of
   1940, as amended (the "1940 Act"), as a diversified, open-end investment
   company established as a Massachusetts business trust. The accompanying
   financial statements and financial highlights are those of the U.S. Treasury
   Securities Money Market Fund, the Prime Money Market Fund, the Municipal
   Money Market Fund, and the Ohio Municipal Money Market Fund (individually, a
   "Fund"; collectively, the "Funds") only. Each Fund is a diversified mutual
   fund, except the Ohio Municipal Money Market Fund which is non-diversified.
 
   The Trust entered into an Agreement and Plan of Reorganization (the
   "Agreement") with the Paragon Portfolio ("Paragon"), a Massachusetts business
   trust. Pursuant to the Agreement all of the assets and liabilities of each
   Paragon Fund transferred to a fund of The One Group in exchange for shares of
   the corresponding fund of The One Group. Changes in net assets and financial
   highlights for periods prior to the reorganization, March 25, 1996, are
   presented for the funds of The One Group only.
 
   The Funds' investment objectives are as follows:

2. SIGNIFICANT ACCOUNTING POLICIES:
 
   The following is a summary of significant accounting policies followed by the
   Trust in the preparation of its financial statements. The policies are in
   conformity with generally accepted accounting principles. The preparation of
   financial statements requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of income and expenses for the
   period. Actual results could differ from those estimates.
 
       SECURITY VALUATION
 
   Securities are valued utilizing the amortized cost method permitted in
   accordance with Rule 2a-7 under the 1940 Act. Under the amortized cost
   method, discount or premium is amortized on a constant basis to the maturity
   of the security. In addition, the Funds may not (a) purchase any instrument
   with a remaining maturity greater than thirteen months unless such instrument
   is subject to a demand feature, or (b) maintain a dollar-weighted average
   maturity which exceeds 90 days.
 
       REPURCHASE AGREEMENTS
 
       The Funds may invest in repurchase agreements with institutions that Banc
   One Investment Advisors Corporation (the "Advisor") has determined are
   creditworthy. Each repurchase agreement is recorded at cost. The Fund
   requires that the securities purchased in a repurchase 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.
 
       SECURITY TRANSACTIONS AND RELATED INCOME
 
   Security transactions are accounted for on a trade date basis. Net realized
   gains or losses on sales of securities are determined on the specific
   identification cost method. Interest income and expenses are recognized on
   the accrual basis. Interest income, including any discount or premium, is
   accrued as earned using the effective interest method.
 
       SECURITIES LENDING
 
   To generate additional income, the Funds may lend up to 33% of securities in
   which they are invested pursuant to agreements requiring that the loan be
   continuously secured by cash, U.S. Government or U.S. Government Agency
   securities, shares of an investment trust or mutual fund, or any combination
   of cash and such securities as collateral equal at all times to at least 100%
   of the market value plus accrued interest on the securities lent. The Funds
   continue to earn interest on securities lent while simultaneously seeking to
   earn interest on the investment of collateral. Collateral is marked to market
   daily to provide a level 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 risk. 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, 1997, the following Fund had securities
   with the following amortized cost on loan (amount in thousands):

                                                                               OF LOANED

                                                                            ---------------
            <S>                                                             <C>
            U.S. Treasury Securities Money Market Fund...................      $307,101
</TABLE>
 
       The loaned securities were fully collateralized by cash and U.S.
       Government securities as of June 30, 1997.
 
       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.
       Net income for this purpose consists of interest accrued and discount
       earned (including both original issue discount and market discount) less
       amortization of any market premium and accrued expenses. 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 generally
       due to differences in separate class expenses.
 
       Net investment income and net capital gain distributions are determined
       in accordance with income tax regulations which may differ from generally
       accepted accounting principles. These differences are primarily due to
       differing treatments of expiring capital loss carryforwards and deferrals
       of certain losses. Permanent book and tax differences, if any, have been
       reclassified among the components of net assets.
 
       FEDERAL INCOME TAXES
 
       Each Fund intends to continue to qualify as a regulated investment
       company by complying with the provisions available to certain investment
       companies as defined in applicable sections of the Internal Revenue Code,
       and to make distributions of net investment income and net realized
       capital gains sufficient to relieve it from all, or substantially all,
       federal income taxes.
 
3. SHARES OF BENEFICIAL INTEREST:
 
   The Trust has an unlimited number of shares of beneficial interest, with no
   par value, which may, without shareholder approval, be divided into an
   unlimited number of series of such shares and any series may be classified or
   reclassified into one or more. The Trust is registered to offer forty series
   and five classes of shares: Fiduciary, Class A, Class B, Class C and Service.
   Currently, the Trust consists of thirty three active funds and not all funds
   can offer all classes of shares. During the year ended June 30, 1995, Service
   Shares transferred to Class A Shares. As of June 30, 1997 there were no
   shareholders in Class C or the Service Class of the Funds. Shareholders are
   entitled to one vote for each full share held and will vote in the aggregate
   and not by class or series, except as otherwise expressly required by law or
   when the Board of Trustees has determined that the matter to be voted on
   affects only the interest of shareholders of a particular class or series.
   The following is a summary of transactions in Fund shares for the fiscal
   years ending June 30, 1997 and 1996:

4. INVESTMENT ADVISORY, ADMINISTRATIVE, 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 0.35% of the average daily net assets of the U.S.
   Treasury Securities Money Market Fund, the Prime Money Market Fund and the
   Municipal Money Market Fund and 0.30% of the average daily net assets of the
   Ohio Municipal Money Market Fund.
 
   The Trust and The One Group Services Company (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
   each Fund's average daily net assets 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 and the
   Government 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% on Trust net assets
   (excluding the Investor Funds and the Institutional Money Market Funds) over
   $2 billion. The Advisor also serves as Sub-Administrator to each Fund of the
   Trust, pursuant to an agreement between the Administrator and the Advisor.
   Pursuant to this agreement, the Advisor performs many of the Administrator's
   duties, for which the Advisor receives a fee paid by the Administrator.
 
   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 Shares, Class B Shares and Service Class Shares are
   subject to distribution and shareholder services plans (the "Plans") pursuant
   to Rule 12b-1 under the 1940 Act. As provided in the Plan, 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, 1.00% of the average daily net assets of Class B
   and C 0.75% of the average daily net assets of the Service Class Shares of
   each of the Funds. The Distributor has voluntarily agreed to limit payments
   under the Plan to 0.25% of average daily net assets of the Class A Shares of
   each Fund and 0.55% of average daily net assets of the Service Class Shares
   of each Fund. Up to 0.25% of the fees payable under the Plan may be used as
   compensation of shareholder services by the Distributor and/or financial
   institutions and intermediaries. Fees paid under the Plan 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. Fiduciary
   Class Shares of each Fund are offered without distribution fees.
 
   Certain officers of the Trust are affiliated with the Administrator. Such
   officers receive no compensation from the Funds for serving in their
   respective roles.

5. CONCENTRATION OF CREDIT RISK:
 
   The Ohio Municipal Money Market Fund invests primarily in debt obligations
   issued by the State of Ohio and its political subdivisions, agencies and
   public authorities to obtain funds for various public purposes. The Fund is
   more susceptible to economic and political factors adversely affecting
   issuers of Ohio's specific municipal securities than are municipal bond funds
   that are not concentrated in these issuers to the same extent.
 
6. REORGANIZATION:
 
   The Trust entered an Agreement and Plan of Reorganization with Paragon
   pursuant to which all of the assets and liabilities of each Paragon Fund
   transferred to a fund of The One Group in exchange for shares of the
   corresponding fund of The One Group. The Paragon Treasury Money Market Fund
   transferred its assets and liabilities to the U.S. Treasury Securities Money
   Market Fund. The reorganization, which qualified as a tax-free exchange for
   federal income tax purposes, was completed on March 25, 1996 following
   approval by shareholders of the Paragon Portfolio at a special shareholder
   meeting. The following is a summary of shares outstanding, net assets and net
   asset value per share immediately before and after the reorganization:

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1997
 
To the Shareholders and Board of Trustees of
  The One Group Family of Mutual Funds:
 
We have audited the accompanying statements of assets and liabilities of the
U.S. Treasury Securities Money Market Fund, the Prime Money Market Fund, the
Municipal Money Market Fund and the Ohio Municipal Money Market Fund (four
series of The One Group Family of Mutual Funds), including the schedules of
portfolio investments, as of June 30, 1997, and the related statements of
operations, statements of changes in net assets, and the financial highlights
for each of the periods presented. These financial statements and financial
highlights are the responsibility of The One Group Family of Mutual Funds'
management. Our responsibility is to express an opinion on these financial
statements and the financial highlights based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. 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. Our procedures included
confirmation of securities owned as of June 30, 1997 by correspondence with the
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
U.S. Treasury Securities Money Market Fund, the Prime Money Market Fund, the
Municipal Money Market Fund and the Ohio Municipal Money Market Fund as of June
30, 1997, the results of their operations, the changes in their net assets and
the financial highlights for each of the periods presented, in conformity with
generally accepted accounting principles.

1. ORGANIZATION:
 
   The One Group (the "Trust") is registered under the Investment Company Act of
   1940, as amended (the "1940 Act"), as an open-end investment company
   established as a Massachusetts business trust. The accompanying financial
   statements and financial highlights are those of the Investor Growth Fund,
   the Investor Growth & Income Fund, the Investor Conservative Growth Fund and
   the Investor Balanced Fund (individually a "Fund", collectively the "Funds")
   only. The Funds are each offered in Fiduciary Class, Class A, Class B and
   Class C Shares. Class A Shares are subject to initial sales charges, imposed
   at the time of purchase, in accordance with the Funds' prospectuses. Certain
   redemptions of Class B and Class C Shares are subject to contingent deferred
   sales charges in accordance with the Funds' prospectuses.
 
   The Funds investment objectives are as follows:

2. SIGNIFICANT ACCOUNTING POLICIES:
 
   The following is a summary of significant accounting policies followed by the
   Trust in preparation of its financial statements. The policies are in
   conformity with generally accepted accounting principles. The preparation of
   financial statements requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of income and expenses for the
   period. Actual results could differ from those estimates.
 
       SECURITY VALUATION
 
       Investments in The One Group mutual funds (the "Underlying Funds") are
       valued at the closing net asset value per share of each Underlying Fund
       on the day of valuation. Short-term investments maturing in 60 days or
       less are valued at amortized cost, which approximates market value.
 
       SECURITY TRANSACTIONS AND RELATED INCOME
 
       Purchases and sales of the underlying funds are accounted for on a trade
       date basis. Net realized gains or losses on sales of the underlying funds
       are determined on the specific identification cost method. Other income
       and expenses are recognized on the accrual basis. Distributions from the
       underlying funds and dividends to the Funds' shareholders are recorded on
       the ex-dividend date.

NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 1997
 
       EXPENSES
 
       Expenses directly attributable to a Fund are charged directly to that
       Fund, while the expenses which are attributable to more than one fund of
       the Trust are allocated among the respective Funds. Each class of shares
       bears its pro-rata portion of expenses attributable to its series, except
       that each class separately bears expenses related specifically to that
       class, such as distribution fees.
 
       DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
 
       Dividends from net investment income are declared and paid monthly for
       the Funds. 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
       generally due to differences in separate class expenses.
 
       Distributions from net investment income and from net capital gains are
       determined in accordance with income tax regulations which may differ
       from generally accepted accounting principles. These differences are
       primarily due to differing treatments for expiring capital loss
       carryforwards and deferrals of certain losses. Permanent book and tax
       basis differences, which affect shareholder distributions, will be
       reclassified to additional paid-in capital.
 
       FEDERAL INCOME TAXES
 
       The Trust treats each Fund as a separate entity for Federal income tax
       purposes. Each Fund intends to continue to qualify as a regulated
       investment company by complying with the provisions available to certain
       investment companies as defined in applicable sections of the Internal
       Revenue Code, and to make distributions from net investment income and
       from net realized capital gains sufficient to relieve it from all, or
       substantially all, Federal income taxes.
 
3. SHARES OF BENEFICIAL INTEREST:
 
   The Trust has an unlimited number of shares of beneficial interest, with no
   par value, which may, without shareholder approval, be divided into an
   unlimited number of series of such shares and any series may be classified or
   reclassified into one or more classes. The Trust is registered to offer forty
   series and five classes of shares: Fiduciary, Class A, Class B, Class C and
   Service. Currently, the Trust consists of thirty three active funds, and not
   all funds can offer all classes of shares. During the year ended June 30,
   1997, there were no shareholders in Class C or the Service Class of the
   Funds. Shareholders are entitled to one vote for each full share held and
   will vote in the aggregate and not by class or series, except as otherwise
   expressly required by law or when the Board of Trustees has determined that
   the matter to be voted on affects only the interest of shareholders of a
   particular class or series. The following is a summary of transactions in
   Fund shares for the period from December 10, 1996 (commencement of
   operations) through June 30, 1997:

   to 0.05% of the average net assets of the Investor Growth Fund, the Investor
   Growth & Income Fund, the Investor Conservative Growth Fund and the Investor
   Balanced Fund, respectively.
 
   The Trust and The One Group Services Company (the "Administrator"), a
   wholly-owned subsidiary of The BISYS Group, Inc., are parties to an
   administrative agreement under which the Administrator provides services for
   a fee that is computed daily and payable monthly, at an annual rate of 0.10%
   on the first $500 million of each Fund's average daily net assets, 0.075% of
   each Fund's average daily net assets between $500 million and $1 billion, and
   0.05% of each Fund's average daily net assets when Fund assets exceed $1
   billion. The Advisor also serves as Sub-Administrator to each fund of the
   Trust, pursuant to an agreement between the Administrator and the Advisor.
   Pursuant to this agreement, the Advisor performs many of the Administrator's
   duties, for which the Advisor receives a fee paid by the Administrator.
 
   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 Shares, Class B Shares and, Class C Shares are
   subject to a distribution and shareholder services plan (the "Plan") pursuant
   to Rule 12b-1 under the 1940 Act. As provided in the Plans, the Trust will
   pay the Distributor a fee of 0.35% of the average daily net assets of Class A
   Shares of each of the Funds and 1.00% of the average daily net assets of the
   Class B Shares and Class C Shares of each of the Funds. Currently, the
   Distributor has voluntarily agreed to limit payments under the Plans to 0.25%
   of average daily net assets of the Class A Shares of each Fund. Up to 0.25%
   of the fees payable under the Plans may be used as compensation for
   shareholder services by the Distributor and/or financial institutions and
   intermediaries. Fees paid under the Plans may be applied by the Distributor
   toward (i) compensation for its services in connection with distribution
   assistance or provision of shareholder services; or (ii) payments to
   financial institutions and intermediaries such as banks, (including
   affiliates of the Advisor), brokers, dealers and other institutions,
   including the Distributor's affiliates and subsidiaries as compensation for
   services or reimbursement of expenses incurred in connection with
   distribution assistance or provision of shareholder services. Fiduciary Class
   Shares of each Fund are offered without distribution fees. For the period
   ended June 30, 1997, the Distributor received $1,185,022 from commissions
   earned on sales of Class A Shares and redemptions of Class B Shares, of
   which, the Distributor re-allowed $1,181,695 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 and to reimburse the Funds for certain
   expenses. For the period ended June 30, 1997, fees in the following amounts
   were waived and reimbursed from the funds (amounts in thousands):

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1997
 
To the Shareholders and Board of Trustees of
  The One Group Family of Mutual Funds:
 
We have audited the accompanying statements of assets and liabilities of the
Investor Growth Fund, the Investor Growth & Income Fund, the Investor
Conservative Growth Fund and the Investor Balanced Fund (four series of The One
Group Family of Mutual Funds), including the schedules of portfolio investments,
as of June 30, 1997, and the related statements of operations, statements of
changes in net assets and the financial highlights for the period then ended.
These financial statements and financial highlights are the responsibility of
The One Group Family of Mutual Funds' management. Our responsibility is to
express an opinion on these financial statements and the financial highlights
based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. 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. Our procedures included
confirmation of securities owned as of June 30, 1997 by correspondence with the
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Investor Growth Fund, the Investor Growth & Income Fund, the Investor
Conservative Growth Fund and the Investor Balanced Fund as of June 30, 1997, the
results of their operations, the changes in their net assets and the financial
highlights for the period then ended, in conformity with generally accepted
accounting principles.

NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 1997
 
1. ORGANIZATION:
 
   The One Group (the "Trust") is registered under the Investment Company Act of
   1940, as amended (the "1940 Act"), as an open-end investment company
   established as a Massachusetts business trust. The accompanying financial
   statements and financial highlights are those of the Treasury Only Money
   Market Fund and the Government Money Market Fund (individually a "Fund",
   collectively the "Funds") only. The Funds are diversified mutual funds and
   are not offered in multiple classes.
 
   The Funds' investment objectives are as follows:
 
<TABLE>
<CAPTION>
                    FUND                                           OBJECTIVE
      --------------------------------     ---------------------------------------------------------
      <S>                                  <C>
      Treasury Only Money Market Fund      High current income with liquidity and stability of
                                            principal with the added assurance of a fund that does
                                            not purchase securities that are subject to repurchase
                                            agreements.
 
      Government Money Market Fund         High current income with liquidity and stability of
                                            principal.
</TABLE>
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
   The following is a summary of significant accounting policies followed by the
   Trust in the preparation of its financial statements. The policies are in
   conformity with generally accepted accounting principles. The preparation of
   financial statements requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of income and expenses for the
   period. Actual results could differ from those estimates.
 
       SECURITY VALUATION
 
       Securities are valued utilizing the amortized cost method permitted in
       accordance with Rule 2a-7 under the 1940 Act. Under the amortized cost
       method, discount or premium is amortized on a constant basis to the
       maturity of the security. In addition, the Funds may not (a) purchase any
       instrument with a remaining maturity greater than thirteen months unless
       such instrument is subject to a demand feature, or (b) maintain a
       dollar-weighted average maturity which exceeds 90 days.
 
       REPURCHASE AGREEMENTS
 
       The Government Money Market Fund may invest in repurchase agreements with
       institutions that Banc One Investment Advisors (the "Advisor") has
       determined are creditworthy. 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.
 
       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. Interest income, including any discount
       or premium, is accrued as earned using the effective interest method.
 
       SECURITIES LENDING
 
       To generate additional income, the Funds may lend up to 33% 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.

NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 1997
 
       Government Agency securities, shares of an investment trust or mutual
       fund, or any combination of cash and such securities as collateral equal
       at all times to at least 100% of the market value plus accrued interest
       on the securities lent. The Funds continue to earn interest on securities
       lent while simultaneously seeking to earn interest on the investment of
       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 judgement of the
       Advisor, the consideration which can be earned currently from such
       securities loans justifies the attendant risk. 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, 1997, the
       following Fund had securities with the following amortized cost on loan
       (amount in thousands):

            Treasury Only Money Market Fund..............................      $116,076
</TABLE>
 
       The loaned securities were fully collateralized by cash and U.S.
       Government securities as of June 30, 1997.
 
       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.
 
       DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
 
       Dividends from net investment income are declared daily and paid monthly.
       Net investment income for this purpose consists of interest accrued and
       discount earned (including both original issue discount and market
       discount) less amortization of any market premium and accrued expenses.
       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 expiring capital loss
       carryforwards and deferrals of certain losses. Permanent book and tax
       basis differences, if any, have been reclassified among the components of
       net assets.
 
       ORGANIZATION COSTS
 
       Costs incurred by the Trust in connection with its organization,
       including the fees and expenses of registering and qualifying its shares
       for distribution have been deferred and are being amortized using the
       straight-line method over a period of five years beginning with the
       commencement of each Fund's operations. All such costs, which are
       attributable to more than one fund of the Trust, have been allocated
       among the respective funds pro-rata, based on the relative net assets of
       each Fund. In the event that any of the initial shares are redeemed
       during such period by any holder thereof, the related Fund will be
       reimbursed by such holder for any unamortized organization costs in the
       proportion as the number of initial shares being redeemed bears to the
       number of initial shares outstanding at the time of redemption.
 
       FEDERAL INCOME TAXES
 
       The Trust treats each Fund as a separate entity for Federal income tax
       purposes. 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 of net investment income and net
       realized capital gains sufficient to relieve it from all, or
       substantially all, Federal income taxes.
 
3. SHARES OF BENEFICIAL INTEREST:
 
   The Trust has an unlimited number of shares of beneficial interest, with no
   par value, which may, without shareholder approval, be divided into an
   unlimited number of series of such shares and any series may be classified or
   reclassified into one or more classes. The Trust is registered to offer forty
   series and five classes of shares: Fiduciary, Class A, Class B, Class C and
   Service Class. Currently, the Trust consists of thirty three active Funds
   and, not all Funds can offer all classes of shares. As of June 30, 1997,
   there were no shareholders in the Class C or Service Class of the Funds.
   Shareholders are entitled to one vote for each full share held and will 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.
 
4. INVESTMENT ADVISORY, ADMINISTRATIVE AND DISTRIBUTION AGREEMENTS:
 
   The Trust and Advisor are parties to an investment advisory agreement under
   which the Advisor is entitled to receive a fee, computed daily and paid
   monthly, equal to 0.08% of the average daily net assets of each Fund.
 
   The Trust and The One Group Services Company (the "Administrator"), a
   wholly-owned subsidiary of The BISYS Group, Inc., are parties to an
   administrative agreement under which the Administrator provides services for
   a fee that is computed daily and paid monthly at an annual rate of 0.05% of
   each Fund's average daily net assets. The Advisor also serves as
   Sub-Administrator to each fund of the Trust, pursuant to an agreement between
   the Administrator and the Advisor. Pursuant to this agreement, the Advisor
   performs many of the Administrator's duties, for which the Advisor receives a
   fee paid by the Administrator.
 
   The One Group Services Company (the "Distributor") and the Trust are parties
   to a distribution agreement under which shares of the Funds are sold on a
   continuous basis. No compensation is paid to the Distributor for distribution
   services for 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 ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1997
 
To the Shareholders and Board of Trustees of
  The One Group Family of Mutual Funds:
 
We have audited the accompanying statements of assets and liabilities of the
Treasury Only Money Market Fund and the Government Money Market Fund (two series
of The One Group Family of Mutual Funds), including the schedules of portfolio
investments, as of June 30, 1997, and the related statements of operations for
the year then ended, statements of changes in net assets for the two years in
the period then ended, and the financial highlights for each of the periods
indicated herein. These financial statements and financial highlights are the
responsibility of The One Group Family of Mutual Funds' management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. 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. Our procedures included
confirmation of securities owned as of June 30, 1997 by correspondence with the
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Treasury Only Money Market Fund and the Government Only Money Market Fund as of
June 30, 1997, the results of their operations, the changes in their net assets
and the financial highlights for the periods indicated herein, in conformity
with generally accepted accounting principles.
