Note 4. Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the treasury stock method by dividing net income by the weighted average number of dilutive common shares outstanding during the period. Diluted shares outstanding is calculated by adding to the weighted average shares outstanding any potential dilutive securities outstanding for the period. Potential dilutive securities include stock options, restricted stock units, performance-based stock awards and shares to be purchased under the Company’s employee stock purchase plan.

For purposes of the diluted net income per share calculation, potential dilutive securities are excluded from the calculation if their effect would be anti-dilutive. As such, basic and diluted net loss per share are the same for periods with a net loss.

The Company’s basic and diluted net income per share were as follows:

For each of the three and six months ended September 30, 2022 and 2021, approximately 0.2 million shares of common stock underlying outstanding securities related to out-of-the-money stock options and performance-based awards where milestones were not met were not included in the computation of diluted earnings per share because their inclusion would be anti-dilutive or such shares are contingently issuable upon meeting performance criteria in the periods presented.
