Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

For the third quarter and first three quarters of fiscal 2016, we recognized total stock-based compensation expense (including stock options, restricted stock units, cash-settled restricted stock units, and performance shares) of $23.1 million and $60.5 million, respectively. For the third quarter and first three quarters of fiscal 2015, we recognized total stock-based compensation expense of $11.4 million and $46.4 million, respectively. These amounts are inclusive of discontinued operations. Included in the total stock-based compensation expense for the third quarter and first three quarters of fiscal 2016 was $0.5 million and $0.7 million, respectively, related to stock options granted by a subsidiary in the subsidiary's shares to the subsidiary's employees. The expense for these stock options was $0.3 million and $0.9 million, respectively, for the third quarter and first three quarters of fiscal 2015. For the first three quarters of fiscal 2016, we granted 1.0 million restricted stock units at a weighted average grant date price of $43.64, 0.8 million cash-settled restricted stock units at a weighted average grant date price of $44.49, 1.6 million stock options at a weighted average exercise price of $43.14, and 0.3 million performance shares at a weighted average grant date price of $41.70.

Performance shares are granted to selected executives and other key employees with vesting contingent upon meeting various Company-wide performance goals. The performance goals for the performance periods ending in fiscal 2016 and 2017 are based upon our earnings before interest, taxes, depreciation, and amortization ("EBITDA") return on capital, and revenue growth, each measured over the defined performance period. The awards actually earned will range from zero to two hundred twenty percent of the targeted number of performance shares for the performance periods ending in fiscal 2016 and 2017. A payout equal to 25% of approved target incentive is required to be paid out for each performance period, as applicable, if we achieve a threshold level of EBITDA return on capital for the performance periods ending in fiscal 2016 and 2017. The performance goal for the first year of the performance period ending in fiscal 2018 is based upon an overarching earnings per share goal and EBITDA return on capital. The performance goal for the last two years of the performance period ending in fiscal 2018 is based on an overarching earnings per share goal and the underlying performance goal for the remaining two year period is expected to be set at the start of fiscal 2017. The awards actually earned will range from zero to two hundred percent of the targeted number of performance shares for the performance period ending in fiscal 2018. Awards, if earned, will be paid in shares of our common stock. Subject to limited exceptions set forth in the performance share plan, any shares earned will be distributed at the end of the performance period. The value of the performance shares is adjusted based upon the market price of our common stock and current forecasted targets at the end of each reporting period and amortized as compensation expense over the vesting period.

The weighted average value of stock options granted during the first three quarters of fiscal 2016 was $5.08 per option based upon a Black-Scholes methodology.
