STOCK-BASED COMPENSATION |
STOCK-BASED COMPENSATION | NOTE 12 — STOCK-BASED COMPENSATION The Company issues stock options and restricted stock units to employees under Stock Awards Plans approved by stockholders. Restricted stock units (“RSUs”) are issued to non-employee directors under a Director Restricted Stock Unit Plan and the 2016 Equity Incentive Plan, and stock options were formally issued to non-employee directors under a Director Stock Option Plan. Options are awarded with the exercise price equal to the market price on the date of grant and generally become exercisable over three years and expire 10 years after grant. RSUs granted to employees generally vest over three years. Director RSUs generally vest over one year. Compensation expense attributable to employee stock options for the first three months of 2017 was approximately $6.9 million ($4.6 million after tax). The income tax benefit related to this compensation expense was approximately $2.3 million. Approximately $6.0 million of the compensation expense was recorded in selling, research & development and administrative expenses and the balance was recorded in cost of sales. Compensation expense attributable to stock options for the first three months of 2016 was approximately $8.9 million ($5.9 million after tax). The income tax benefit related to this compensation expense was approximately $3.0 million. Approximately $7.9 million of the compensation expense was recorded in selling, research & development and administrative expenses and the balance was recorded in cost of sales. The Company uses historical data to estimate expected life and volatility. The weighted-average fair value of stock options granted under the Stock Awards Plans was $11.85 and $10.59 per share during the first three months of 2017 and 2016, respectively. These values were estimated on the respective grant dates using the Black-Scholes option-pricing model with the following weighted-average assumptions:
