Certain of the Company’s restricted stock units are considered participating securities which require the use of the two-class method when computing basic and diluted earnings per share. During the three and six months ended June 30, 2012, approximately 0.3 million and 0.4 million restricted stock units, respectively, and options to purchase approximately 0.4 million shares were not included because they were anti-dilutive. During the three and six months ended June 30, 2011, approximately 0.3 million restricted stock units and options to purchase approximately 0.4 million shares were not included because they were anti-dilutive.

The Carry-Over Units are considered participating securities because dividend payments are not forfeited even if the underlying award does not vest. Accordingly, the Company uses the two-class method when computing basic and diluted earnings per share. During the year ended December 31, 2011 and for the period from the Separation Date through December 31, 2010, approximately 0.2 million and 0.4 million restricted stock units, respectively, and options to purchase approximately 0.4 million and 0.3 million shares, respectively, were not included because they were anti-dilutive.
