Stock-Based Compensation Programs |
Stock-Based Compensation Programs | 14.Stock-Based Compensation Programs The company has shareholder-approved stock plans under which options and stock-settled appreciation rights (SSARs) have been granted to employees at the market value of the company’s stock at the date of grant. In general, options and SSARs are exercisable in four equal installments commencing one year from the date of grant and terminating 10 years from the date of grant. A total of 1,231,865 stock options and SSARs were granted in February 2015. These options and SSARs cannot be traded in any equity market. However, based on the Black-Scholes option pricing model, options and SSARs granted in 2015 and 2014 have estimated weighted average fair values at the date of grant of $14.20 per share and $9.81 per share, respectively. The actual value an employee may realize will depend on the excess of the stock price over the exercise price on the date the option or SSAR is exercised. Consequently, there is no assurance that the value realized by an employee will be at or near the value estimated. The fair values were estimated using the following weighted average assumptions:
|  | February 2015 |  | January 2014 |
Expected dividend yield |  | 0.79 | % | 1.06 | %
Expected stock price volatility |  | 22.11 | % | 21.41 | %
Risk-free interest rate |  | 1.39 | % | 1.65 | %
Expected life of options (in years) |  | 5.85 years |  | 5.50 years |
In February 2015 and January 2014, the company’s board of directors granted 116,559 and 143,305 performance-contingent restricted stock units (PCEQs), respectively, to key employees. These PCEQs vest three years from the date of grant, and the number of shares available at the vesting date are based on the company’s growth in economic valued added (EVA®) dollars in excess of the EVA® dollars generated in the calendar year prior to grant as the minimum threshold, ranging from zero to 200 percent of each participant’s assigned award opportunity. If the minimum performance goals are not met, the shares will be forfeited. Grants under the plan are being accounted for as equity awards and compensation expense is recorded based upon the most probable outcome using the closing market price of the shares at the grant date. On a quarterly and annual basis, the company reassesses the probability of the goals being met and adjusts compensation expense as appropriate.
