Stockholders entitled to fractional shares as a result of the reverse stock split received a cash payment in lieu of receiving fractional shares.

The 2014 Warrants and 2015 Warrants were exercisable immediately on issuance and have a seven-year life. The 2014 Warrants and 2015 Warrants were recorded as a liability and re-measured at each reporting date using the then-current assumptions. In connection with the completion of the IPO, the 2014 Warrants and the 2015 Warrants were automatically converted into warrants exercisable for Common Stock, resulting in the reclassification of the related warrant liability to additional paid-in capital as the warrants to purchase shares of Common Stock met the criteria to be accounted for as equity instruments. The warrant liability was re-measured to fair value prior to reclassification to additional paid-in capital. As of September 30, 2015, the Company had no outstanding warrant liability.   The following table provides a roll-forward of the fair value of the 2014 Warrants and 2015 Warrants determined by Level 3

In June 2015, the Company’s board of directors adopted and the Company’s stockholders approved the 2015 Stock Incentive Plan (“2015 Plan”), which became effective immediately prior to the effectiveness of the Company’s IPO. Subsequent to the Company’s IPO, option grants are awarded to eligible participants only under the 2015 Plan.   The 2015 Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock units, stock appreciation rights and other stock-based awards. The Company’s employees, officers, directors and consultants and advisors are eligible to receive awards under the 2015 Plan. The maximum number of shares of Common Stock that may be delivered in satisfaction of awards under the 2015 Plan is 1,068,287 shares, plus (1) 25,942 shares that were available for grant under the 2008 Plan immediately prior to the closing of the IPO, (2) the number of shares of Common Stock subject to outstanding awards under the 2008 Plan upon closing of the IPO that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right and (3) an annual increase, to be added the first day of each fiscal year, beginning with the fiscal year ending December 31, 2016 and continuing until, and including, the fiscal year ending December 31, 2025, equal to the lowest of 1,297,334 shares of Common Stock, 4% of the number of shares of Common Stock outstanding on the first day of the fiscal year and an amount determined by the Company’s board of directors.   As of September 30, 2015, the Company had reserved 1,466,274 shares of Common Stock under the 2008 Plan, of which none remained available for future issuance.  As of September 30, 2015, the Company had reserved 1,106,685 shares of Common Stock under the 2015 Plan, of which 860,948 shares remained available for future issuance.   Stock Options   A summary of the Company’s stock option activity and related information

funds, which approximate their fair value due to their short-term nature. In connection with the completion of the IPO, warrants exercisable for Preferred Stock were automatically converted into warrants exercisable for Common Stock, resulting in the reclassification of the related warrant liability to additional paid-in capital as the warrants to purchase shares of Common Stock are accounted for as equity instruments (Note 6). </div><div style="margin-left:0%;margin-right:0%;"> </div><div style="margin-left:0%;margin-right:0%;"></div> </div>
