Basic and Diluted Net Income Per Share

13.  Basic and Diluted Net Income Per Share

Basic net income per share is calculated by dividing the net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents.  Diluted net income per share is calculated by dividing the net income attributable to common stockholders by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method and the if-converted method.  For purposes of this calculation, stock options are considered to be common stock equivalents and are only included in the calculation of diluted net income per share when their effect is dilutive.  No shares were excluded from the diluted net income per share calculation for the quarterly and three quarterly periods ended July 3, 2021.  For the quarterly and three quarterly periods ended June 27, 2020, 7.1 million and 7.1 million shares, respectively, were excluded from the diluted net income per share calculation as their effect would be anti-dilutive.

The following tables provide a reconciliation of the numerator and denominator of the basic and diluted net income per share calculations.
