Basic and diluted earnings per share are computed independently for each of the quarters presented. Therefore, the sum of the quarterly amounts may not equal the total computed for the year. Net income for the quarter ended December 31, 2012 was negatively impacted primarily by acquisition-related costs arising from our acquisition of Thomas Medical and the impairment of a cost-method investment.
