|Share-based Payment Arrangement [Abstract]|
|Stock-Based Compensation||Stock-Based Compensation
The Company grants stock-based awards under its 2014 Incentive Stock Plan (the “2014 Plan”) and the 2012 Stock Plan (the “2012 Plan”). The 2014 Plan replaced the 2012 Plan, but the 2012 Plan remains in effect for the administration of awards made prior to its replacement by the 2014 Plan. The shares issued as a result of stock-based compensation transactions generally have been funded with the issuance of new shares of the Company’s common stock.
The Company may grant the following types of incentive awards under the 2014 Plan: (i) non-qualified stock options; (ii) incentive stock options; (iii) stock appreciation rights; (iv) restricted stock; and (v) restricted stock units. Each award granted under the 2014 Plan is subject to an award agreement that incorporates, as applicable, the exercise price, the term of the award, the periods of restriction, the number of shares to which the award pertains, and such other terms and conditions as the plan committee determines. Awards granted under the 2014 Plan are classified as equity awards, which are recorded in stockholders’ equity in the Company’s consolidated balance sheets.
The Company’s closing price on the date of grant is the basis of fair value of its common stock used in determining the value of share-based awards. To the extent the value of the Company’s share-based awards involves a measure of volatility, the Company uses available historical volatility of the Company’s common stock over a period of time corresponding to the expected stock option term. The Company uses the simplified method to calculate the expected term of stock option grants to employees as the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees. Accordingly, the expected life of the options granted is based on the average of the vesting term, which is generally four years and the contractual term, which is generally ten years. The Company will continue to evaluate the appropriateness of utilizing such method. The risk-free interest rate is based on United States Treasury yields in effect at the date of grant for periods corresponding to the expected stock option term.
The Company has computed the fair value of all options granted using the Black-Scholes-Merton model during the six months ended June 30, 2021 and 2020, using the following assumptions:
The information below summarizes the stock options activity for the six months ended June 30, 2021:
For the three months ended June 30, 2021 and 2020, stock-based compensation expense for stock options was $176,169 and $128,652, respectively. For the six months ended June 30, 2021 and 2020, stock-based compensation expense for stock options was $327,048 and $275,660, respectively.
Restricted stocks granted to employees generally vest in four equal annual installments. Restricted stocks granted to non-employee directors typically vest in full one year after the date of grant.
The information below summarizes the restricted stock activity for the six months ended June 30, 2021:
For the three months ended June 30, 2021 and 2020, stock-based compensation expense for restricted stock was $107,395 and $87,429, respectively. For the six months ended June 30, 2021 and 2020, stock-based compensation expense for restricted stock was $203,010 and $190,813, respectively.
