Less: accumulated depreciation and amortization	(44,734		)	(39,491		)
Total property and equipment, net	$	27,006		$	27,249

Depreciation expense for the years ended December 31, 2012, 2011 and 2010 was $8.9 million, $9.1 million and $9.1 million, respectively. In addition, software amortization expense for the years ended December 31, 2012, 2011 and 2010 was $0.9 million, $0.6 million and $0.6 million, respectively.

In September 2010, the Company wrote off a sterilizer system that was not yet placed in service. The total amount of the write-off was $0.9 million and was recorded as an “Asset impairment charge” in the consolidated statement of comprehensive income (loss) for the year ended December 31, 2010. During the assembly and construction of the sterilizer asset, the EPA issued a ruling that phases out one of the gases used to operate the sterilizer, which effectively limited the cost-effectiveness and useful life of the asset.
