The Company had the following common stock option activity during the thirteen weeks ended March 30, 2019:

The following table summarizes the Company’s restricted stock unit ("RSU") activity for the thirteen weeks ended March 30, 2019, and details regarding the awards outstanding and exercisable at March 30, 2019 (in thousands):

During the thirteen weeks ended March 30, 2019,  191 RSUs that vested were time-based and 44 were performance-based. For the RSUs awarded, the number of shares issued on the date of vest is net of the minimum statutory withholding requirements that we pay in cash to the appropriate taxing authorities on behalf of our employees. For those employees who elect not to receive shares net of the minimum statutory withholding requirements, the appropriate taxes are paid directly by the employee. During the thirteen weeks ended March 30, 2019, we withheld 284 shares to satisfy $287 of employees’ tax obligations. Although shares withheld are not issued, they are treated as a common stock repurchase in our consolidated financial statements, as they reduce the number of shares that would have been issued upon vesting.

For the thirteen weeks ended March 30, 2019, we recorded compensation costs related to stock options and RSUs of $554. For the thirteen weeks ended March 31, 2018 we recorded compensation costs related to stock options and RSUs of $1,003.  March 30, 2019, there was unrecognized compensation expense related to stock options and RSUs of $2,680.
