[1] The weighted average grant date fair values of stock options granted by former Parent prior to June 12, 2013, were adjusted to reflect former Parent's stock option modification for the $1.00 special dividend. The modification decreased the per share grant date fair value but increased the number of stock options held by the option-holder to preserve the value of the options immediately before and after the $1.00 special dividend. There was no incremental compensation expense resulting from this modification.

[2] The weighted average grant date fair values of stock options granted by former Parent prior to the separation date were adjusted for the separation conversion on September 27, 2013.
