INTANGIBLE ASSETS AND GOODWILL

NOTE 4—INTANGIBLE ASSETS AND GOODWILL

The Company conducted its annual two-step impairment test of intangible assets and goodwill as of June 30, 2011 and determined that there was no impairment. The Company also tests its intangible assets and goodwill between the annual impairment test if events occur or circumstances change that would more likely than not reduce the fair value of the Company or its assets below their carrying amounts. No events have occurred that would trigger further impairment testing of the Company’s intangible assets and goodwill during the years ended December 31, 2011 and 2010.

Amortization expense for the years ended December 31, 2011, 2010, and 2009, totaled $130,000, $130,000, and $141,000, respectively. Estimated intangible asset amortization expense, based on existing intangible assets, for the years ending December 31, 2012, 2013, 2014, and 2015, is $130,000, $62,000, $13,000, and $7,000, respectively.
