Stock-Based Incentive Plans

On June 26, 2013, the Company adopted the 2013 Equity Incentive Plan (“2013 Plan”). The Company has stock option awards outstanding under four stock-based incentive plans as of December 31, 2012 and under five stock-based incentive plans as of September 30, 2013, including, in each case, two plans that were assumed as part of the acquisition of ScanScout. The Company has restricted stock unit awards outstanding under its 2013 Plan.

Plan Provisions Under the 2013 Equity Incentive Plan

Upon the effectiveness of the Company’s IPO, the Board of Directors determined that the 2013 Plan would be the only plan under which stock-based awards will be issued by the Company on a going-forward basis. The 2013 Plan provides for the awards of incentive stock options, non-qualified stock options, restricted stock, restricted stock units and other stock-based awards; however, only incentive and non-qualified stock option awards and restricted stock unit awards have been issued through September 30, 2013 under the 2013 Plan. The 2013 Plan states that awards may be granted to such non-employee directors, officers, employees and consultants as the Board of Directors shall in its discretion select. Only employees of the Company are eligible to receive grants of incentive stock option awards. Stock option awards are generally granted at the fair market value of the Company’s common stock on the date of grant. Stock option grants generally vest over periods up to four years, with the first 25% of the grant vesting after one year, and monthly vesting thereafter. Stock option grants generally have a term not to exceed a total of 10 years. Restricted stock unit awards are generally granted at the fair market value of the Company’s common stock on the date of grant. Restricted stock unit awards granted to our non-employee directors generally vest after a period of one year, with 100% vesting on the vesting date. As of September 30, 2013, there were 972,139 shares of common stock that may be issued pursuant to stock-based awards available for issuance under the 2013 Plan.
