Earnings Per Share [Abstract] |
Net Income Per Share | Net Income Per Share CRA calculates basic earnings per share using the two-class method. CRA calculates diluted earnings per share using the more dilutive of either the two-class method or treasury stock method. The two-class method was more dilutive for fiscal 2022, fiscal 2021, and fiscal 2020. Under the two-class method, net earnings are allocated to each class of common stock and participating security as if all the net earnings for the period had been distributed. CRA's participating securities consist of unvested share-based payment awards that contain a nonforfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common shareholders Net earnings allocable to these participating securities were not material for fiscal 2022, fiscal 2021, and fiscal 2020. The following table presents the calculation of basic and diluted net income per share (in thousands, except per share data):

The following table presents the anti-dilutive share-based awards that were excluded from the calculation of common stock equivalents for purposes of computing diluted weighted average shares outstanding (in thousands):
| Year Ended |  | Year Ended |  | Year Ended
