|Disclosure of Compensation Related Costs, Share-based Payments [Abstract]|
In December 2014, the Board of Directors and stockholders of Pieris Pharmaceuticals, Inc. adopted the 2014 Employee, Director and Consultant Equity Incentive Plan (the “Pieris Plan”), which became effective upon closing of the Acquisition. The Pieris Plan is intended to encourage ownership of common stock by the Company’s employees and directors and certain of their consultants, including employees of Pieris AG, in order to attract and retain such people, to induce them to work for the benefit of the Company and to provide additional incentive for them to promote the Company’s success. The Pieris Plan reserves 3,200,000 shares of the Company´s common stock for issuance. In addition, the Pieris Plan provides for an “evergreen” provision whereby the number of shares of the Company´s common stock reserved for issuance under the Pieris Plan shall be automatically increased on January 1 of each of year commencing in fiscal 2016 by the lesser of (i) 1,000,000 shares, (ii) 4% of the number of shares of the Company´s common stock outstanding on such date, and (iii) such other amount determined by the Compensation committee of the Board of Directors. As of June 30, 2015, options to purchase 1,470,235 shares of the Company´s common stock are outstanding under the Pieris Plan to its executive officers and directors. 40,235 of these shares were granted during the second quarter of 2015. All other shares were granted in the fourth quarter of 2014. In addition, options to purchase 1,146,500 shares are outstanding under the Pieris Plan to other employees and consultants. 25,000 of these shares were granted during the first quarter of 2015, 32,000 of these shares were granted during the second quarter of 2015 and 1,089,500 were granted during the fourth quarter of 2014. As a result of such grants, 583,265 of the Company´s common stock remain available for future issuances under the Pieris Plan.
Stock options granted under the Pieris Plan may be either incentive stock options (“ISOs”), or nonqualified stock options. The Board of Directors determines who will receive options, the vesting periods (which are generally three years) and the exercise prices. Options have a maximum term of ten years. The exercise price of stock options granted under the Pieris Plan must be at least equal to the fair market value of the common stock on the date of grant. The Pieris Plan become effective in December 2014, therefore there was no stock-based compensation expense in the three and six months ended June 30, 2014.
Total stock-based compensation expense, related to all share-based awards under the Pieris Plan to executive officers, directors, employees and consultants recognized for the three and six months ended June 30, 2015, was comprised of the following:
