Goodwill and Other Intangible Assets
[4] Goodwill and Other Intangible Assets

During 2011, the Company completed a reorganization which resulted in the formation of the Specialty Contractors reporting unit and reportable segment.  The Specialty Contractors reporting unit consists of the following subsidiary companies: WDF, FSE, Nagelbush, Fisk, Powerco Electric Corporation (“Powerco”), Desert Mechanical, Inc. (“DMI”) (all previously included in the Building reporting unit), and Superior Gunite (previously included in the Civil reporting unit).  The reorganization enables the Company to focus on vertical integration through increased self-performed work capabilities, while maintaining the specialty contractors business with third parties, and it will strengthen the Company's position as a full-service contractor with greater control over scheduled delivery and risk management.  The Company reallocated goodwill between its reorganized reporting units based on a relative fair value assessment in accordance with the guidance on segment reporting.  Changes in the carrying amount of goodwill during 2011 and 2010 are shown in the tables below (in thousands):

In the fourth quarter of 2011, the Company performed its impairment evaluation of goodwill and other intangible assets.  There was no change in the carrying amount of goodwill and other intangible assets as a result of this evaluation (see Note 1(g) for additional disclosure of the impairment evaluation).

During 2011 the Company's intangible assets significantly increased as a result of the Company's major acquisition strategy, and the Company has also started to amortize certain of its trade name intangible assets based on the period over which the economic benefits of the assets are expected to be realized.  Other intangible assets consist of the following (in thousands):
