ASC Topic 260, “Earnings Per Share” (“ASC Topic 260”) requires companies with unvested participating securities to utilize a two-class method for the computation of Net income attributable to Company per share. The two-class method requires a portion of Net income attributable to Company to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents, if declared. Net income attributable to Company allocated to these participating securities was immaterial for three months ended March 31, 2012 and 2011 and therefore not excluded from Net income attributable to Company per share calculation. In addition, the Company had stock options outstanding that were anti-dilutive totaling 6 million and 3 million shares for the three months ended March 31, 2012 and 2011, respectively.
