(1) In the first quarter of 2012, we signed an agreement to sell our facility in Richmond, Virginia for $1.5 million. This facility had a book value of approximately $1.8 million prior to the signing of the agreement, and we recorded an impairment charge of approximately $0.4 million as of December 31, 2011, which represented the write down to the selling price minus approximately $0.1 million of estimated selling costs. The transaction closed in the second quarter of 2012.
