DEAN FAMILY OF FUNDS

NOTES TO FINANCIAL STATEMENTS

September 30, 2005 (Unaudited)

1. Organization

The Dean Family of Funds (the Trust) is registered under the Investment Company Act of 1940 as an open-end management investment company. The Trust was organized as an Ohio business trust under a Declaration of Trust dated December 18, 1996. The Trust has established four series: the Large Cap Value Fund, the Small Cap Value Fund, the Balanced Fund, and the International Fund (formerly the International Value Fund) (the Funds). The Trust was capitalized on March 17, 1997, when the initial shares of each Fund (except for the International Fund) were purchased at $10.00 per share. The International Fund was capitalized on October 13, 1997, when the initial shares of the International Fund were purchased at $10.00 per share.

The Large Cap Value Fund seeks to provide capital appreciation and dividend income over the long-term by investing primarily in the common stocks of large companies.

The Small Cap Value Fund seeks to provide capital appreciation by investing primarily in the common stocks of small companies.

The Balanced Fund seeks to preserve capital while producing a high total return by allocating its assets among equity securities, fixed-income securities and money market instruments.

The International Fund seeks to provide long-term capital growth by investing primarily in the common stocks of foreign companies.

The Funds each offer two classes of shares: Class A shares (sold subject to a maximum front-end sales load of 5.54% of net asset value and a distribution and service fee of up to 0.25% per annum of the average daily net assets allocable to Class A shares) and Class C shares (sold subject to a maximum contingent deferred sales load of 1.00% of net asset value if redeemed within a one-year period from purchase and a distribution and service fee of up to 1.00% per annum of average daily net assets allocable to Class C shares). Each Class A and Class C share of a Fund represents identical interests in the Fund’s investment portfolio and has the same rights, except that (i) Class C shares may bear the expenses of higher distribution and service fees, which is expected to cause Class C shares to have a higher expense ratio and to pay lower dividends than Class A shares; (ii) certain other class specific expenses will be borne solely by the class to which such expenses are attributable; (iii) each class has exclusive voting rights with respect to matters relating to its own distribution arrangements; and iv) each class has different exchange privileges.

The Funds indemnify the Trust’s officers and trustees for certain liabilities that might arise from their performance of their duties as officers and Trustees of the Funds. Additionally, in the normal course of business, the Funds enter into contracts that contain a variety of representations and warranties and that provide general indemnifications. The Funds’ maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Funds that have not yet occurred. However, based on experience, the Funds expect the risk of loss to be remote.

2. Significant Accounting Policies

The following is a summary of the Trust’s significant accounting policies:

Security valuation – Portfolio securities are valued as follows: (1) securities that are traded on stock exchanges are valued at the last reported sale price as of the close of the regular session of trading on the New York Stock Exchange on the day the securities are being valued, or, if not traded on a particular day, at the closing bid price; (2) securities traded in the NASDAQ over-the-counter market are generally valued at the NASDAQ Official Closing Price; (3) securities traded in the over-the-counter market that are not quoted by NASDAQ, are valued at the last sale price as of the close of the regular session of trading on the New York Stock Exchange on the day the securities are being valued or, if the last sale price is not readily available, at the last bid price as quoted by brokers that make markets in the securities; (4) securities that are traded both in the over-the-counter market and on a stock exchange are valued according to the broadest and most representative market; (5) U.S. Government obligations are valued at their most recent bid prices as obtained from one or more of the major market makers for such securities; (6) securities mainly traded on a non-U.S. exchange are generally valued according to the preceding closing values on that exchange; (7) short-term investments with remaining maturities of 60 days or less at the time of purchase are valued at amortized cost; and (8) securities (and other assets) for which market quotations are not readily available are valued at their fair value as determined in good faith in accordance with consistently applied procedures established by and under the general supervision of the Board of Trustees.

If trading in a stock is halted and does not resume before a Fund calculates its net asset value, the Fund may value the security at its fair value. Fair valuation of the Fund’s portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the Fund’s NAV by short-term traders. If an event that may change the value of a security held in a Fund's portfolio occurs after the closing of the applicable market, the Board of Trustees might decide to value the security based on fair value. This may cause the value of the security on the books of the Fund to be significantly different from the market quotation and may affect the calculation of the Fund's net asset value.
