Stockholders’ Equity and Share-Based Compensation
Non-Controlling Interest
Non-controlling interests represent equity interests in consolidated subsidiaries that are not attributable, either directly or indirectly, to the Company (i.e., minority interests). Non-controlling interests consist of the minority equity holders' proportionate share of the equity of AutoMD. Ownership interests in subsidiaries held by parties other than the Company are presented as non-controlling interests within stockholders' equity, separately from the equity held by the Company. Revenues, expenses, net income (loss) and other comprehensive loss are reported in the consolidated financial statements at the consolidated amounts, which includes amounts allocated to both the Company's interest and the non-controlling interests in AutoMD. Net loss and other comprehensive loss is then attributed to the Company's interest and the non-controlling interests. Net income (loss) to non-controlling interests is deducted from net income (loss) in the consolidated statements of comprehensive operations to determine net income (loss) attributable to the Company's common stockholders.
The following table summarizes the Company’s stock option activity under the AutoMD 2014 Equity Incentive Plan (the "AMD Plan") for the thirty-nine weeks ended October 1, 2016, and details regarding the options outstanding and exercisable at October 1, 2016:

During the thirty-nine weeks ended October 1, 2016, all RSU's that vested were time-based. For the majority of RSUs awarded, the number of shares issued on the date the RSUs 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 thirty-nine weeks ended October 1, 2016, we withheld 131 shares to satisfy $371 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 and thirty-nine weeks ended October 1, 2016, we recorded compensation expense of $821 and $2,537, respectively. As of October 1, 2016, there was unrecognized compensation expense of $895 related to unvested RSUs based on awards that are expected to vest. The unrecognized compensation expense is expected to be recognized over a weighted-average period of 0.87 years.
