Of the options outstanding as of June 30, 2016, 560,698 were vested, 134,990 were estimated to vest in future periods and 501 were estimated to be forfeited prior to their vesting. As of June 30, 2016, there was approximately $77,800 of total unrecognized compensation cost, net of estimated forfeitures, related to unvested stock options. Such cost is expected to be recognized over a weighted-average period of approximately six months.

All options are exercisable immediately upon grant. Options vest ratably, generally over a 33-month period commencing in the fourth month after the grant date. We have the right to repurchase common stock issued upon the exercise of an option upon an optionee’s termination of service to us prior to full vesting at the option’s exercise price.

The following table presents summaries of the status and activity of our restricted stock awards for the three-month period ended June 30, 2016. We include the common stock underlying the restricted stock award in shares outstanding once such common stock has vested and the restriction has been removed (“releases” or “released”). The common stock vests ratably, generally over a 33-month period commencing in the fourth month after the award date.
