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 the Company per share. The two-class method requires a portion of net income attributable to the 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 losses are not allocated to nonvested shares in periods that the Company determines that those shares are not obligated to participate in losses. For the periods that the Company recognized net income, net income attributable to the Company allocated to these participating securities was excluded from net income attributable to the Company’s stockholders in the numerator of the earnings per share computation.
