Amortization expense for the three month periods ended March 31, 2012 and 2011 totaled $2.3 million and $2.4 million, respectively. The Company estimates that the total amortization expense will be $8.6 million in 2012, $7.4 million in 2013, $7.3 million in 2014, $6.6 million in 2015, $6.4 million in 2016, $5.6 million in 2017, and $21.6 million thereafter.

The Company accounts for goodwill and identifiable intangible assets in accordance with ASC 360, Intangibles—Goodwill and Other. Under this standard, the Company assesses the impairment of goodwill and indefinite-lived intangible assets at least annually, on October 31, and whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

During the fourth quarter of 2011, the Company performed its annual assessment and determined that the goodwill and certain trade names within the FSTech Group reporting unit were impaired and recorded impairment charges of $14.8 million and $7.4 million, respectively. In the first quarter of 2012 the Company determined, upon finalization of the second step of the impairment analysis, that no adjustment to the estimated impairment charge recorded in 2011 was necessary.
