In October 2005, in connection with the exercise by Mr.  Gearon of his right to require the Company to purchase his interest in ATC South America, these options vested in full and were exercised.
Upon exercise of these options, the holders received 4,428 shares of ATC South America, net of 1,596 shares retained by the Company to satisfy employee tax withholding obligations.
The 1,596 shares retained by the Company were treated as a repurchase of a minority interest in accordance with SFAS No.141.
As a result, the Company recorded a purchase price allocation adjustment of $5.6 million as an increase to intangible assets and a corresponding increase in minority interest as of the date of acquisition.
The holders had the right to require the Company to purchase their shares of ATC South America at their then fair market value six months and one day following their issuance.
In April 2006, this repurchase right was exercised, and the Company paid these holders an aggregate of $18.9 million in cash, which was the fair market value of their interests on the date of exercise of their repurchase right, as determined by the Company’s Board of Directors with the assistance of an independent financial advisor.12.

Impairment charges and gains (losses) are presented net of taxes.
Tower Construction Services Unit—In November 2004, the Company consummated the sale of its tower construction services unit (previously included in the Company’s network development services segment), including $3.9 million of inventory and $5.2 million of net property and equipment.
Total consideration was approximately $9.1 million, including $6.8 million of cash proceeds, subject to adjustment, and the buyer’s assumption of $2.3 million of capital lease obligations.
Pursuant to this transaction, the Company recorded a net loss on disposal of approximately $1.7 million, which is reflected in loss from discontinued operations, net, in the accompanying consolidated statement of operations for the year ended December 31, 2004.
Kline, Iron & Steel—In March 2004, the Company sold substantially all the assets of its steel fabrication and tall tower construction service subsidiary, Kline, Iron & Steel (previously included in the Company’s network development services segment), for approximately $4.0 million.
The Company had previously recorded charges to impair Kline’s net assets and reduce their carrying value to the estimated proceeds expected upon disposal.
Verestar—In December 2003, Verestar filed for protection under Chapter 11 of the federal bankruptcy laws.
Under generally accepted accounting principles, consolidation is generally required for investments of more than 50% of the outstanding voting stock of an investee, except when control is not held by the majority owner.
Under these rules, legal reorganization or bankruptcy represent conditions which can preclude consolidation in instances where control rests with the bankruptcy court, rather than the majority owner.
Accordingly, due to the bankruptcy filing, the Company ceased to consolidate Verestar’s financial results beginning December 22, 2003.
As described in note 9, the Company has incurred costs in connection with its involvement in the bankruptcy proceedings of Verestar of $0.9 million, $1.3 million and $0.1 million, which are reflected within the net loss on disposal of discontinued operations in the accompanying consolidated statements of operations for the years ended December 31, 2006, 2005 and 2004, respectively.
The net loss on disposal for the year ended December 31, 2004 also includes a $1.3 million net gain related to certain contractual obligations that were settled for less than the Company’s original estimate.
