ASC Topic 260, “Earnings Per Share” 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 (loss) attributable to Company allocated to these participating securities was immaterial for the three and nine months ended September 30, 2018 and 2017 and therefore not excluded from net income attributable to Company per share calculation.

The Company had stock options outstanding that were anti-dilutive totaling 11 million shares and 17 million shares for each of the three and nine months ended September 30, 2018, and 17 million shares and 13 million shares for each of the three and nine months ended September 30, 2017, respectively.
