The Company adopted a stock incentive plan (the “1996 Plan”) in November 1996 and reserved 1,500,000 shares of Common Stock for issuance under the 1996 Plan. The 1996 Plan provided for the issuance of stock options and stock appreciation rights. The Company ceased granting new awards under the 1996 Plan as of January 21, 2011, and the 1996 Plan expired in accordance with its terms on January 8, 2012. The Company adopted a stock incentive plan (the “2010 Plan”) in October 2010 and reserved 600,000 shares of Common Stock for issuance under the 2010 Plan. The 2010 Plan replaced the Company’s 1996 Plan. The 2010 Plan permits the award of incentive and non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock and performance shares (collectively referred to as “Share-Based Awards”) as well as dividend equivalent rights and cash-based awards. On October 27, 2014, the Board of Directors, subject to the approval of the Company’s shareholders, which was received at the 2015 annual meeting of shareholders, adopted an amendment to the 2010 Plan to, among other matters, reserve for issuance an additional 750,000 shares and extend to 2025 the time period awards may be granted under the 2010 Plan. As of August 31, 2019, the number of remaining shares available for future grants under the 2010 Plan was 364,060. Share-based compensation, which includes expense related to Share-Based Awards, has been recorded in the accompanying Consolidated Statements of Income in selling and administrative expenses.

All Share-Based Awards issued to management were recommended to the Board of Directors by the Compensation Committee and approved by the Board of Directors. All Share-Based Awards issued to the Company’s non-employee members of the Board of Directors (the “Directors”) under the 2010 Plan were recommended to the Board of Directors by the Compensation Committee and approved by the Board of Directors. Share-Based Awards granted to non-employee Directors are granted on the third business day following the annual shareholders’ meeting.

In fiscal 2019, 2018 and 2017, a total of 291, 234 and 735 shares of fully vested unrestricted stock, respectively, were granted to certain non-employee Directors of the Company. Accordingly, compensation expense related to the 2019, 2018 and 2017 unrestricted stock was recognized on the date of grant.

In fiscal 2019, 2018 and 2017, the Company granted a total of 5,000, 5,000 and 4,940 stock appreciation rights, respectively, under the 2010 Plan to the Company’s non-employee Directors. Such stock appreciation rights were fully vested upon grant, expire on the earlier of the eighth anniversary of the grant date or the second anniversary of the date that the Director ceases to be a member of the Board of Directors and must be settled in stock at the time of exercise. Accordingly, compensation expense related to the stock appreciation rights was recognized on the date of grant.

All stock appreciation rights issued to employees were granted with an exercise price equal to the fair market value of the Company’s Common Stock on the date of grant. Other than certain stock appreciation rights which vest 20% on each anniversary of the grant date over a five-year period, stock appreciation rights are subject to a five-year cliff-vesting schedule under which the awards become fully vested or exercisable after five years from the date of grant and expire ten years after the grant date. Share-Based Awards granted to the Company’s non-employee Directors were fully vested as of the date of grant. Prior to fiscal 2009, non-employee Director Share-Based Award grants in the form of stock options expired ten years from the grant date. Beginning in fiscal 2009, non-employee Director Share-Based Award grants in the form of stock options and stock appreciation rights expire on the earlier of the eighth anniversary of the grant date or the second anniversary of the date that the Director ceases to be a member of the Board of Directors.

Time-based restricted stock units granted to employees vest either 20% on each anniversary of the grant date over a five-year period, 33% on each anniversary of the grant date over a three-year period or on a five-year cliff vesting schedule under which the awards become fully vested after five years from the date of grant. Generally, performance-based restricted stock units granted to employees are earned based on whether and the extent to which the Company achieves certain consolidated revenues and adjusted operating margins. Any such performance-based restricted stock units earned will vest in three equal annual amounts with the first vesting date being the date that the performance criteria have been determined to have been met.

On April 21, 2016, the Company entered into a Restricted Stock Award Agreement (the “Award Agreement”) with the Company’s former Chief Executive Officer Ronald D. Croatti, pursuant to which the Company granted 140,000 shares (the “Performance Restricted Shares”) of restricted stock to Mr. Croatti. The fair value of the Performance Restricted Shares was the closing price on April 21, 2016, which was $111.13.

Upon Mr. Croatti’s death in the third quarter of fiscal 2017, 46,666 Performance Restricted Shares of Common Stock were forfeited and 46,667 Performance Restricted Shares of Class B Common Stock that were earned in the performance period for the second half of fiscal 2016 became immediately vested. Additionally, the remaining 24,334 and 22,333 Performance Restricted Shares of Class B Common Stock and Common Stock, respectively, were earned in the performance period for fiscal 2017 upon the achievement of the performance criteria under the Award Agreement and became fully vested. During fiscal 2017, the Company recognized expense on the Award Agreement of $8.8 million, of which $5.4 million was due to the accelerated vesting of Performance Restricted Shares upon Mr. Croatti’s death.

As of August 31, 2019, the total compensation cost not yet recognized related to non-vested Share-Based Awards was approximately $10.4 million. The weighted average period over which compensation cost for Share-Based Awards will be recognized is 2.1 years.

The fair value of each stock appreciation right is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions used:

Fiscal year ended August	2019			2018			2017
Risk-free interest rate		3.07	%		2.23	%		1.58	%
Expected dividend yield		0.48	%		0.18	%		0.21	%
Expected life in years		7.24			7.41			7.43
Expected volatility		22.9	%		23.1	%		24.0	%

The weighted average fair values of Share-Based Awards granted in the form of stock appreciation rights during fiscal years 2019, 2018 and 2017 were $46.20, $47.51 and $34.74, respectively.
