No fractional Restricted Share Units shall be created, and the Committee shall, in its discretion, determine an equivalent benefit for any fractional Restricted Share Units that might be created by such adjustments Any Performance Share Units subject to your PSU Grant that are not awarded to you by the Committee will be automatically forfeited, will revert to the Plan, and you will have no rights with respect to such forfeited Performance Share Units.
