Earnings Per Share [Abstract] |
Net Income Per Share | Net Income Per Share Basic net income per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. The dilutive effect of outstanding options and equity incentive awards is reflected in diluted net income per share by application of the treasury stock method. The calculation of diluted net income per share excludes all anti-dilutive common shares. The following table sets forth the computation of basic and diluted net income per share for the three and nine months ended September 30, 2020 and 2019 (in millions, except per share amounts):
