Earnings Per Share [Abstract] |
Net Income per Share | Net Income per Share Basic net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average shares outstanding, including potentially dilutive shares of common equivalents outstanding during the period. The dilutive effect of potential shares of common stock are determined using the treasury stock method. On October 15, 2023, all of our outstanding shares of Class B common stock automatically converted into the same number of shares of Class A common stock pursuant to the terms of our then effective Amended and Restated Certificate of Incorporation. Because shares of Class B common stock were outstanding for the three months ended April 30, 2023, we have disclosed earnings per share for Class A and Class B common stock for the three months ended April 30, 2023. For the three months ended April 30, 2023, the computation of fully diluted net income per share of Class A common stock assumes the conversion from Class B common stock, while the fully diluted net income per share of Class B common stock does not assume the conversion of those shares. The numerators and denominators of the basic and diluted net income per share computations for our common stock are calculated as follows (in thousands, except per share data):
