Net Income per Share |
Net Income per Share | 15. Net Income per Share CRA calculates basic and diluted earnings per common share using the two-class method. 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. Basic earnings per common share excludes dilution and is calculated by dividing net earnings allocable to common shares by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocable to common shares by the weighted-average number of common shares as of the balance sheet date, as adjusted for the potential dilutive effect of non-participating share-based awards. Net earnings allocable to these participating securities were not significant for the first quarter of fiscal 2018 or fiscal 2017. The following table presents a reconciliation from net income to the net income available to common shareholders (in thousands):
|  | March 31, 2018 |  | April 1, 2017 |
Net income, as reported |  | $ | 4,886 |  | $ | 2,853 |

The following presents a reconciliation of basic to diluted weighted average shares of common stock outstanding (in thousands):
|  | March 31, 2018 |  | April 1, 2017 |
Basic weighted average shares outstanding |  |  | 8,285 |  |  | 8,419 |
Stock options and restricted stock units |  |  | 295 |  |  | 202 |

Diluted weighted average shares outstanding |  |  | 8,580 |  |  | 8,621 |

For the first quarter ended March 31, 2018, 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 amounted to 5,689 shares. For the first quarter ended April 1, 2017, 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 amounted to 8,234 shares. These share-based awards each period were anti-dilutive because their exercise price exceeded the average market price over the respective period. On May 3, 2017 and February 15, 2018, CRA announced its Board of Directors authorized the repurchase of up to an additional $20.0 million and $20.0 million, respectively, of CRA's common stock. Repurchases under these programs are discretionary and CRA may make such purchases under any of these programs in the open market (including under any Rule 10b5-1 plan adopted by CRA) or in privately negotiated transactions, in each case in accordance with applicable insider trading and other securities laws and regulations. CRA records the retirement of its repurchased shares as a reduction to common stock. During the first quarter ended March 31, 2018, CRA repurchased and retired 162,892 shares under these share repurchase programs at an average price per share of $51.13 and in the first quarter ended April 1, 2017, there were no shares repurchased or retired under these share repurchase programs. As of March 31, 2018, there was approximately $21.2 million available for future repurchases under these programs.
