Under applicable accounting guidance, companies in a loss position are required to use basic weighted-average common shares outstanding in the calculation of diluted loss per share. Therefore, as a result of our loss from continuing operations available to Genworth Financial, Inc.’s common stockholders and net loss available to Genworth Financial, Inc.’s common stockholders for the year ended December 31, 2014, we were required to use basic weighted-average common shares outstanding in the calculation of diluted loss per share for the year ended December 31, 2014, as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 5.6 million would have been antidilutive to the calculation. If we had not incurred a loss from continuing operations available to Genworth Financial, Inc.’s common stockholders and net loss available to Genworth Financial, Inc.’s common stockholders for the year ended December 31, 2014, dilutive potential weighted-average common shares outstanding would have been 502.0 million.
