Awards of stock options and nonvested shares representing approximately 10 million and 8 million additional shares of common stock were outstanding for the second quarter and first half of 2019, respectively, and approximately 7 million for the second quarter and first half of 2018, but were not included in the computation of diluted weighted-average shares outstanding because their effect would have been antidilutive.
