Stock-Based Compensation

5. Stock-Based Compensation

Stock-based compensation includes expense charges for all stock-based awards to employees and directors. These awards include stock option grants and restricted stock awards.

Stock-based compensation expense related to internal labor is capitalized to software and patents based on direct labor hours charged to capitalized software and patent costs.

Determining Fair Value

Stock Options

Valuation and Amortization Method. The Company estimates the fair value of stock options on the date of grant (measurement date) using the Black-Scholes option valuation model. The Company amortizes the fair value of all awards on a straight-line basis over the requisite service periods, which are generally the vesting periods.

Expected Life. The expected life of awards granted represents the period of time that they are expected to be outstanding. The Company determines the expected life based on historical experience with similar awards, giving consideration to the contractual terms and vesting schedules of the awards. Stock options granted generally vest over three years and have contractual terms of ten years.

Expected Volatility. The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of its common stock based on historical prices over the most recent period commensurate with the expected life of the award.

Risk-Free Interest Rate. The Company determines the risk-free interest rate using current U.S. treasury yields for bonds with a maturity commensurate with the expected life of the award.

Expected Dividend Yield. The expected dividend yield is derived by the Company’s expected annual dividend rate over the expected term divided by the fair value of the Company’s common stock at the grant date.

There were no stock options granted during the three and six months ended June 30, 2018 and 2017.

Restricted Stock

The fair value of restricted stock awarded is based on the fair market value of the Company’s common stock on the date of the grant (measurement date), and is recognized over the vesting period of the award using the straight-line method. Restricted stock awards granted generally vest over three to four years for employee grants and one to three years for director grants.
