At September 30, 2011, we recorded a $2.8 million impairment of our acquired internally developed 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. Amortization expense related to intangible assets totaled $0.5 million, $0.5 million, $1.5 million and $1.6 million for the three and nine months ended September 30, 2010 and 2011, respectively.

Estimated future amortization expense related to intangible assets as of September 30, 2011 is as follows (in thousands):

2011 (Remaining 3 months)	$	494
2012		1,688
2013		911
