Share-based Compensation [Abstract] |
Stock Option Plans | NOTE I Stock Option Plans Employee Incentive PlansIn November 2010, shareholders approved the 2010 Master Stock Incentive Plan (the Plan). The Plan extends through September 2020 and allows for the granting of nonqualified stock options, incentive stock options, restricted stock, restricted stock units, stock appreciation rights (SAR), dividend equivalents, and other stock-based awards. Options under the Plan are granted to key Employees at market price at the date of grant. Options are generally exercisable for up to 10 years from the date of grant. The Plan also allows for the granting of performance awards to a limited number of key executives. As administered by the Human Resources Committee of the Company’s Board of Directors to date, these performance awards are payable in common stock and are based on a formula which measures performance of the Company over a three-year period. Performance award expense under these plans totaled $0.1 million in Fiscal 2015, $0.7 million in Fiscal 2014, and $0.1 million in Fiscal 2013. Stock options for non-executives are exercisable in equal increments over three years. Stock options issued after Fiscal 2010 become exercisable for executives in equal increments over three years. Stock options issued from Fiscal 2005 to Fiscal 2010 became exercisable for most executives immediately upon the date of grant. For Fiscal 2015, the Company recorded pre-tax compensation expense associated with stock options of $9.5 million and recorded $3.1 million of related tax benefit. For Fiscal 2014 and 2013, the Company recorded pre-tax compensation expense associated with stock options of $9.9 million and $8.3 million, respectively, and $3.2 million and $2.7 million, respectively, of related tax benefit. Stock-based employee compensation cost is recognized using the fair-value based method. The Company determined the fair value of these awards using the Black-Scholes option pricing model, with the following assumptions:
|  | 2015 |  |  | 2014 |  |  | 2013 |
Risk - free interest rate |  |  | 0.05 - 2.3% |  |  |  | 0.31 - 2.8% |  |  |  | 0.02 - 1.7% |
Expected volatility |  |  | 18.6 - 26.7% |  |  |  | 18.2 - 28.0% |  |  |  | 22.5 - 29.7% |
Expected dividend yield |  |  | 1.6% |  |  |  | 1.4 - 1.6% |  |  |  | 1.0 - 1.4% |
Expected life |  |  |  |  |  |  |  |  |  |  |  |
Director and officer grants |  |  | 8 years |  |  |  | 8 years |  |  |  | 8 years |
Non - officer original grants |  |  | 7 years |  |  |  | 7 years |  |  |  | 7 years |
Reload grants |  |  | ≤4 years |  |  |  | ≤6 years |  |  |  | ≤5 years |
Black-Scholes is a widely accepted stock option pricing model. The weighted average fair value for options granted during Fiscal 2015, 2014, and 2013, was $9.94, $11.44, and $8.18 per share, respectively, using the Black-Scholes pricing model. Reload grants are grants made to officers or directors who exercised a reloadable option during the fiscal year and made payment of the purchase price using shares of previously owned Company stock. The reload grant is for the number of shares equal to the shares used in payment of the purchase price and/or withheld for minimum tax withholding. Options with a reload provision were no longer issued to officers with more than five years of service, and all directors beginning in Fiscal 2006. The Company continued to issue options with a reload provision to officers with less than five years of service until Fiscal 2011 when this was discontinued.
