____________
(a)
Stock options exercised during the period of July 1, 2016 through December 31, 2016 had an aggregate intrinsic value of $66.2 million.
        
The Company has stock-based compensation plans under which the Company annually grants stock option and restricted stock unit awards. Stock options are granted to employees at exercise prices equal to the fair market value of the Company’s common stock on the dates of grant, with the measurement of stock-based compensation expense recognized in Net earnings based on the fair value of the award on the date of grant. Stock-based compensation expense of $14.0 million and $13.3 million, as well as related tax benefits of $4.9 million and $4.9 million were recognized for the three months ended December 31, 2016 and 2015, respectively. Stock-based compensation expense of $22.8 million and $22.2 million, as well as related tax benefits of $8.1 million and $8.3 million were recognized for the six months ended December 31, 2016 and 2015, respectively.
As of December 31, 2016, the total remaining unrecognized compensation cost related to non-vested stock options and restricted stock unit awards amounted to $8.3 million and $55.8 million, respectively, which will be amortized over the weighted-average remaining requisite service periods of 2.2 years and 1.8 years, respectively.
For stock options issued, the fair value of each stock option was estimated on the date of grant using a binomial option pricing model. The binomial model considers a range of assumptions related to volatility, risk-free interest rate and employee exercise behavior. Expected volatilities utilized in the binomial model are based on a combination of implied market volatilities, historical volatility of the Company’s stock price and other factors. Similarly, the dividend yield is based on historical experience and expected future changes. The risk-free rate is derived from the U.S. Treasury yield curve in effect at the time of grant. The binomial model also incorporates exercise and forfeiture assumptions based on an analysis of historical data. The expected life of the stock option grants is derived from the output of the binomial model and represents the period of time that options granted are expected to be outstanding.
