Basic earnings per share are based on the weighted-average number of common shares outstanding during each period. Diluted earnings per share are based on the weighted-average number of common shares outstanding plus the effect of all dilutive common stock equivalents during each period. The calculation of diluted weighted-average shares excludes the impact of 1 million common stock equivalents for each of the three and nine months ended September 30, 2016 and 2015, respectively.
