NOTE 4. GOODWILL AND INTANGIBLE ASSETS

Goodwill

At June 30, 2013 and December 31, 2012, the Company’s goodwill totaled $163.2 million.  The Company’s annual goodwill impairment test is conducted at November 30 of each calendar year and interim evaluations are performed when the Company determines that a triggering event has occurred that would more likely than not reduce the fair value of its goodwill below its carrying value.  During the second quarter of 2013, no triggering events occurred.

During the second quarter of 2012, due to a decline in the market price of the Company’s stock, the market capitalization of the Company was below the carrying value of equity, which the Company considered a triggering event and therefore performed an interim step 1 impairment test.  As a result of the impairment test, the Company recorded a preliminary goodwill impairment charge of $12.0 million in the second quarter of 2012.
