To the best knowledge of the Reporting Persons, none of the entities or persons identified in this Item 2 has, during the past five years, been convicted of any criminal proceeding (excluding traffic violations or similar misdemeanors), nor been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Item 5. Interest in Securities of the Issuer --------------------------------------------- (a),(b) According to the Issuer's most recent Form 10-Q, there were 46,165,579 shares of Common Stock issued and outstanding as of March 31, 2005. 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) 2,606,300 shares of CUSIP NO. 4506B109 SCHEDULE 13D Page 10 of 13 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, or on behalf of an entity for which Blum L.P. serves as investment advisor, which represents 5.6% of the outstanding shares of the Common Stock; (ii) 3,151,100 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 partnership for which it serves as the managing limited partner, which represents 6.8% of the outstanding shares of the Common Stock; (iii) 470,200 shares of the Common Stock held by Blum GP III which serves as general partner of Blum GP III LP which, in turn, serves as the general partner of Blum Strategic III, which represents 1.0% of the outstanding shares of the Common Stock; and (iv) 70,700 shares of the Common Stock that are legally owned by The Nuclear Decommissioning Trust of Dominion Nuclear Connecticut, Inc. ("Dominion Connecticut") and 70,700 shares of the Common Stock that are legally owned by Virginia Electric and Power Company Qualified Nuclear Decommissioning Trust ("Virginia Electric") (collectively, the "Investment Advisory Clients"), with respect to which Blum L.P. has voting and investment power. Each Investment Advisory Client has entered into an investment management agreement with Blum L.P., but neither Investment Advisory Client has any contract, arrangement or understanding with the 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 Investment Advisory Client disclaims membership in a group with any Reporting Person or with the 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., Blum GP II and Blum GP III. 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 6,369,000 shares of the Common Stock, which is 13.8% 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. The filing of this Schedule shall not be construed as an admission that any of the officers, managing members and members of Blum L.P., Blum GP II, Blum GP III LP and Blum GP III, is, for any purpose, the beneficial owner of any of the securities that are beneficially owned by Blum L.P., Blum GP II, Blum GP III LP or Blum GP III. c) During the last 60 days, the Reporting Persons purchased the following shares of Common Stock in the open market: CUSIP NO. 4506B109 SCHEDULE 13D Page 11 of 13 Entity Trade Date Shares Price/Share ------ ---------- ------- ----------- Investment partnerships for 05-05-05 18,100 42.9972 which Blum L.P. serves as the 05-06-05 26,700 43.1463 general partner and on behalf 05-09-05 24,900 43.0894 of an entity for which Blum L.P. 05-11-05 17,700 43.3647 serves as investment advisor. 05-13-05 900 42.9890 05-16-05 700 43.1000 05-19-05 600 43.6390 05-20-05 26,700 43.9523 05-23-05 73,300 45.0759 05-25-05 27,300 44.2537 06-16-05 13,700 47.2106 06-17-05 1,000 47.2600 06-20-05 2,900 47.2457 06-21-05 2,200 47.2600 07-08-05 10,000 51.9701 Entity Trade Date Shares Price/Share ------ --------- ------- ---------- The limited partnerships for 05-13-05 55,100 42.9890 which Blum GP II serves as the 05-16-05 27,800 43.1000 general partner and the managing 05-19-05 30,100 43.6390 limited partner.
