Stock-Based Compensation |
10. Stock-Based Compensation As of March 31, 2014, the Company had 10,245,294 options outstanding. At the Company’s Annual Meeting of the Stockholders held on June 10, 2013, the Company’s stockholders voted to approve the Rexahn Pharmaceuticals, Inc. 2013 Stock Option Plan (the “2013 Plan”). Under the 2013 Plan, the Company grants stock options to key employees, directors and consultants of the Company. A total of 17,000,000 shares of common stock have been reserved for issuance pursuant to the 2013 Plan. As of March 31, 2014, there were 1,425,999 options outstanding under the 2013 Plan, and 15,574,001 shares were available for issuance from the 2013 Plan. On August 5, 2003, the Company established a stock option plan (the “2003 Plan”). Under the 2003 Plan, the Company granted stock options to key employees, directors and consultants of the Company. With the adoption of the 2013 Plan, no new stock options may be issued under the 2003 Plan, but previously issued options under the 2003 Plan remain outstanding until their expiration. As of March 31, 2014, there were 8,819,295 outstanding options under the 2003 Plan. For the majority of the grants to employees, the vesting period is 30% on the first anniversary of the grant date, an additional 30% on the second anniversary of the grant date and the remaining 40% on the third anniversary. Options expire between five and ten years from the date of grant. For grants to non-employee consultants of the Company, the vesting period is between one and three years, subject to the fulfillment of certain conditions in the individual stock agreements, or 100% upon the occurrence of certain events specified in the individual stock agreements. Accounting for Employee Awards The Company’s results of operations for the three months ended March 31, 2014 and 2013 include share-based employee compensation expense totaling $109,442 and $366,111, respectively. Such amounts have been included in the statement of operations in general and administrative and research and development expenses. No income tax benefit has been recognized in the statement of operations for share-based compensation arrangements as the Company has provided for a 100% valuation allowance on its deferred tax assets. Employee stock option compensation expense is the estimated fair value of options granted amortized on a straight-line basis over the requisite vesting service period for the entire portion of the award. Accounting for Non-Employee Awards Stock compensation expenses related to non-employee options were $18,908 and $5,840 for the three months ended March 31, 2014 and 2013, respectively. Such amounts have been included in the statement of operations in general and administrative and research and development expenses.
