(1)	Aggregate intrinsic value is calculated based upon the difference between the exercise price of options or RSUs and the Company’s closing common stock price on December 31, 2014 of $61.93, multiplied by the number of instruments that are vested or expected to vest. Options and RSUs having exercise prices greater than the closing stock price noted above are excluded from this calculation.


(2)	Options, RSUs and performance shares that are expected to vest are net of estimated future forfeitures.
