Equity [Abstract]

Summary of Stock Option Activity

The 2010 Equity Incentive Plan (the “2010 Plan”) provides for equity-based awards to the Company’s employees, directors and consultants. Under the 2010 Plan, the Company initially reserved 1,000,000 shares of common stock for issuance. This number automatically increases on the first trading day of each fiscal year beginning with fiscal 2011, by an amount equal to 1.5% of the shares of common stock outstanding as of the last trading day of the immediately preceding fiscal year; accordingly, 1,961,898 shares of common stock were reserved for issuance as of January 30, 2016. The Company previously had two stock option plans which expired on October 31, 2010. No further awards will be granted under these plans, although all options previously granted and outstanding will remain outstanding until they are either exercised or forfeited. As of January 30, 2016, 829,252 stock options have been granted pursuant to the 2010 Plan.
