CUSIP NO. 45255G101 SCHEDULE 13D Page 9 of 14 Item 3. Source and Amount of Funds or Other Consideration ---------------------------------------------------------- The source of funds for the purchases of securities was the working capital of Blum L.P.'s limited partnerships and investment advisory clients and each of the partnerships for which Blum GP II serves as the sole general partner and managing limited partner. Item 4. Purpose of Transaction ------------------------------- The purpose of the acquisition of the Common Stock is for investment, and the acquisitions of the Common Stock were made in the ordinary course of business and were not made for the purpose of acquiring control of the Issuer. Although no Reporting Person has any specific plan or proposal to acquire or dispose of the Common Stock, consistent with its investment purpose, each Reporting Person at any time and from time to time may acquire additional Common Stock or dispose of any or all of its Common Stock depending upon an ongoing evaluation of the investment in the Common Stock, prevailing market conditions, other investment opportunities, liquidity requirements of the Reporting Persons and/or other investment considerations. Also, consistent with the investment purpose, the Reporting Persons may engage in communications with one or more shareholders of the Issuer, one or more officers of the Issuer and/or one or more members of the board of directors of the Issuer and/or one or more representatives of the Issuer regarding the Issuer, including but not limited to its operations. The Reporting Persons may discuss ideas that, if effected may result in any of the following: the acquisition by persons of additional Common Stock of the Issuer, an extraordinary corporate transaction involving the Issuer, and/or changes in the board of directors or management of the Issuer. Except to the extent the foregoing may be deemed a plan or proposal, none of the Reporting Persons has any plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto. Item 5. Interest in Securities of the Issuer --------------------------------------------- (a),(b) According to the Issuer's most recent Form 10-Q, there were 16,329,233 shares of Common Stock issued and outstanding as of September 20, 2002. Based on such information, after taking into account the transactions described in Item 5(c) below, the Reporting Persons report beneficial ownership of the following shares of Common Stock: (i) 776,691 shares of the Common Stock held by Blum GP II on behalf of the limited partnership for which it serves as the general partner and on behalf of the limited CUSIP NO. 45255G101 SCHEDULE 13D Page 10 of 14 partnership for which it serves as the managing limited partner, which represents 4.8% of the outstanding shares of the Common Stock; (ii) 441,600 shares of the Common Stock held by Blum L.P. and RCBA, Inc. on behalf of the limited partnerships for which Blum L.P. serves as the general partner, which represents 2.7% of the outstanding shares of the Common Stock; and (iii) 278,800 shares of the Common Stock that are legally owned by Carpenters Pension Trust for Southern California ("Carpenters"), 33,800 shares of the Common Stock that are legally owned by United Brotherhood of Carpenters Pension Plan ("UBC") and 23,300 shares of the Common Stock that are legally owned by The Common Fund for the account of its Multi-Strategy Equity Fund ("The Common Fund")(collectively, the "Investment Advisory Clients"), with respect to which Blum L.P. has voting and investment power. The Investment Advisory Clients represent 2.0% of the outstanding shares of the Common Stock. The Common Fund is principally engaged in the business of managing investments for educational institutions. The principal administrative office of The Common Fund is located at 15 Old Danbury Road, Wilton, Connecticut 06897-0812. Each of the Investment Advisory Clients, has entered into an advisory agreement with Blum L.P., but none of the Investment Advisory Clients has any contract, arrangement or understanding with any other Investment Advisory Client, or any other Reporting Person, with respect to the acquisition, ownership, disposition or voting of any shares of the Common Stock. Each of the Investment Advisory Clients disclaims membership in a group with any Reporting Person or with any other Investment Advisory Client, and each disclaims beneficial ownership of any shares beneficially owned by the Reporting Persons other than for their own account. Voting and investment power concerning the above shares are held solely by Blum L.P. and Blum GP II. The Reporting Persons therefore may be deemed to be members in a group, in which case the group would be deemed to have beneficial ownership of an aggregate of 972,791 shares of the Common Stock, which is 6.0% of the outstanding Common Stock. As the sole general partner of Blum L.P., RCBA Inc. is deemed the beneficial owner of the securities over which Blum L.P. has voting and investment power. As Chairman, director and a substantial shareholder of RCBA Inc., Richard C. Blum might be deemed to be the beneficial owner of the securities beneficially owned by RCBA Inc. Additionally, Mr. Blum may be deemed to be the beneficial owner of the securities over which Blum GP II has voting and investment power. Although Mr. Blum is joining in this Schedule as a Reporting Person, the filing of this Schedule shall not be construed as an admission that he, or any of the other shareholders, directors or executive officers of RCBA Inc., managing members and members of Blum GP II, is, for any purpose, the beneficial owner of any of the securities that are beneficially owned by RCBA Inc. or Blum GP II.
