(1)  
Includes charges related to one-time termination benefits and costs associated with capacity reduction of $9.0 million and an impairment loss of $183.3 million primarily related to an impairment of goodwill.
 
(2)  
The assumed exercise of stock-based compensation awards for this period was not considered in the calculation of diluted earnings (loss) per share because the impact would have been anti-dilutive.
 
(3)  
Includes revenues related to an adjustment to a multi-year earn-out arrangement in connection with a business combination entered into during the fourth quarter of 2009 of $1.5 million and an investment gain of $1.2 million.
 
(4)  
Includes revenues related to an adjustment to a multi-year earn-out arrangement in connection with a business combination entered into during the fourth quarter of 2009 of $1.5 million, restructuring charges of $10.3 million (which were presented as a separate line item in the consolidated statements of operations), and revenues of $22.3 million and expenses of $1.0 million attributable to a settlement with CMS.
 
(5)  
We calculated earnings per share for each of the quarters based on the weighted average number of shares and dilutive options outstanding for each period.  Accordingly, the sum of the quarters may not necessarily be equal to the full year income per share.
