Share Based Compensation [Abstract] |
Share Based Compensation | R. SHARE BASED COMPENSATION Share Based Compensation Program Share based compensation is designed to reward employees for their long-term contributions to the Company and provide incentives for them to remain with the Company. The number and frequency of share grants are based on competitive practices, operating results of the Company, and individual performance. As of August 31, 2015, the Company’s share-based compensation plan was the 2015 Long-Term Incentive Plan (the “2015 Plan”). The 2015 Plan was approved by the shareholders of the Company, and became effective on January 26, 2015, and replaced the Company’s 2010 Long Term Incentive Plan. At August 31, 2015 the Company had share based awards outstanding under its 2001 and 2010 Long-Term Incentive Plans. The 2015 Plan provides for awards of stock options, restricted shares, restricted stock units, stock appreciation rights, performance shares and performance stock units to employees and non-employee directors of the Company. The maximum number of shares as to which stock awards may be granted under the 2015 Plan is 626,968 shares, exclusive of any forfeitures from the 2010 Long Term Incentive Plan. At August 31, 2015, 639,715 shares of common stock (including forfeitures from prior plans) remained available for issuance under the 2015 Plan. All stock awards will be counted against the 2015 Plan in a 1 to 1 ratio. If options, restricted stock units or performance stock units awarded under the 2010 Plan terminate without being fully vested or exercised, those shares will be available again for grant under the 2015 Plan. The 2015 Plan also limits the total awards that may be made to any individual.

As of August 31, 2015, there was $4.1 million pre-tax of total unrecognized compensation cost related to nonvested share-based compensation arrangements which is expected to be recognized over a weighted-average period of 1.7 years. Stock Options – Stock option awards have an exercise price equal to the closing price on the date of grant, expire no later than ten years from the date of grant and vest over a four-year period at 25 percent per year. The fair value of stock option awards is estimated using the Black-Scholes option pricing model. The table below shows the annual weighted-average assumptions used for valuation purposes.
|  |  |  |  |  | Grant Year
Weighted-Average Assumptions |  |  |  |  |  | Fiscal 2015 |  | Fiscal 2014
Risk-free interest rate |  |  |  |  |  |  | 2.0% |  |  | 1.9%
Dividend yield |  |  |  |  |  |  | 1.3% |  |  | 0.7%
Expected life (years) |  |  |  |  |  |  | 7 |  |  | 7
Volatility |  |  |  |  |  |  | 53.6% |  |  | 55.2%
Weighted-average grant-date fair value of options granted | $ | 40.66 |  | $ | 40.40
The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant; the dividend yield is calculated as the ratio of dividends paid per share of common stock to the stock price on the date of grant; the expected life is based on historical and expected exercise behavior; and volatility is based on the historical volatility of the Company’s stock price over the expected life of the option.

In connection with the performance stock units, the performance goals are based upon revenue growth and a return on net assets during the performance period. The awards actually earned will range from zero to two hundred percent of the targeted number of performance stock units and will be paid in shares of common stock. Shares earned will be distributed upon vesting on the first day of November following the end of the three-year performance period. The Company is accruing compensation expense based on the estimated number of shares expected to be issued utilizing the most current information available to the Company at the date of the financial statements. If defined performance goals are not met, no compensation cost will be recognized and any previously recognized compensation expense will be reversed. In fiscal 2015 and fiscal 2014, performance stock units that vested represented 27,473 and 46,908, re spectively, of actual shares of common stock issued. The fair value of performance stock units that vested during the period was $1.6 million and $2.6 million for the year ended August 31, 2015 and 2014, respectively.
