During the third quarter of 2011, we recorded a $2.8 million impairment of our acquired software and $0.1 million impairment of our trade name (see Note 1). Additionally, as part of the process of valuing the acquired software we revised the estimated remaining useful life to approximately three years from five, which is subject to further revisions as the facts and circumstances may change in the future. Amortization expense related to identifiable intangible assets totaled $1.1 million, $2.0 million and $2.1 million, for the years ended December 31, 2009, 2010 and 2011, respectively.

Estimated future amortization expense related to identifiable intangible assets is as follows as of December 31, 2011 (in thousands):
