The Company accounts for stock-based compensation under the authoritative guidance which requires that share-based payment transactions with employees be recognized in the financial statements based on their fair value and recognized as compensation expense over the vesting period. The amount of expense recognized during the period is affected by subjective assumptions, including: estimates of the Companys future volatility, the expected term for its stock options, option exercise behavior, the number of options expected to ultimately vest, and the timing of vesting for the Companys share-based awards. The following table sets forth the total stock-based compensation expense resulting from stock options and the employee stock purchase plan included in the Companys condensed consolidated statements of operations and comprehensive loss (in thousands): Three months ended March 31, 2016 2015 Sales and marketing $ 136 $ 504 Clinical, regulatory and research and development 83 99 General and administrative 495 458 Stock-based compensation expense before income taxes $ 714 $ 1,061 (c) Employee Stock Purchase Plan In July 2014, the Companys Board of Directors adopted the 2014 Employee Stock Purchase Plan (the ESPP) which was approved by the Companys stockholders in June 2014 at the Companys Annual Meeting of Stockholders. A total of 671,500 shares of the Companys common stock are reserved for issuance under the plan, which permits eligible employees to purchase common stock at a discount through payroll deductions. The price at which stock is purchased under the ESPP is equal to 90% of the fair market value of the common stock on the first or the last day of the offering period, whichever is lower. Generally, each offering under the ESPP will be for a period of six months as determined by the Companys Board of Directors. Employees may invest up to 20% of their gross compensation through payroll deductions. In no event may an employee invest more than $25 worth of stock in the plan during each calendar year or more than 5,000 shares per offering period.
