.            STOCK-BASED COMPENSATION
 
As of February 28, 2016, the Company had a 2002 Stock Option Plan (the “Plan”), and no other stock-based compensation plan. The Plan has been approved by the Company’s shareholders and provides for the grant of stock options to directors and key employees of the Company. All options granted under the Plan have exercise prices equal to the fair market value of the underlying common stock of the Company at the time of grant, which, pursuant to the terms of the Plan, is the reported closing price of the common stock on the New York Stock Exchange on the date preceding the date the option is granted. Options granted under the Plan become exercisable 25% one year after the date of grant, with an additional 25% exercisable each succeeding anniversary of the date of grant, and expire 10 years after the date of grant. Options to purchase a total of 1,800,000 shares of common stock were authorized for grant under the Plan. At February 28, 2016, 1,466,030 shares of common stock of the Company were reserved for issuance upon exercise of stock options under the Plan, and 234,638 options were available for future grant under the Plan.
 
 
The compensation expense for stock options includes an estimate for forfeitures and is recognized on a straight-line basis over the requisite service period.
 
The future compensation expense to be recognized in earnings before income taxes for options outstanding at February 28, 2016 was $3,212, which is expected to be recognized ratably over a weighted average vesting period of 2.66 years.
 
The Company records its stock-based compensation at fair value. The weighted average fair value for options was estimated at the dates of grants, using the Black-Scholes option pricing model.
 
The following table represents the weighted average fair value and valuation assumptions used for options granted in the 2016, 2015 and 2014 fiscal years:

Risk-free interest rates
    1.57 - 1.86%       2.03 - 2.18%       1.64 - 2.15%  
Expected stock price volatility
    27.91 - 31.71%       31.07 - 31.59%       32.80 - 34.00%  
Expected dividend yields
    1.84 - 2.76%       1.34 - 1.77%       1.46 - 1.67%  
Estimated option terms (years)
    5.3 - 7.9       7.8       6.1 - 8.1  
 
The risk-free interest rates are based on U.S. Treasury rates at the date of grant with maturity dates approximately equal to the estimated term of the options at the date of the grant. Volatility factors are based on historical volatility of the Company’s common stock. The expected dividend yields are based on the regular quarterly cash dividend per share most recently declared by the Company and on the exercise price of the options granted during the 2016 fiscal year. The estimated terms of the options are based on evaluations of the historical and expected future employee exercise behavior.
 
During the fourth quarter of the 2015 fiscal year, the Company’s Board of Directors approved a reduction of $1.50 per share in the exercise price of all outstanding options as a result of the special cash dividend of $1.50 per share paid by the Company in February 2015. The reduction in the exercise price was treated as a modification of the stock options for accounting purposes. The modification, based on the fair value of the options both immediately before and after the modification, resulted in total incremental compensation expenses of $131 and $205 for the 2016 and 2015 fiscal years, respectively, which were recorded in selling, general and administrative expenses.
