(1)Outstanding RSUs represent shares that have not yet been issued because not all conditions necessary to earn the right to benefit from the instruments have been satisfied. The final amount of RSUs distributed depends on the employee’s level of performance achieved and, with the exception of certain retirement-eligible employees, continued service through the vesting date, which could result in changes in vested RSUs. (2)For performance-based RSUs, amount represents the number of target shares at grant date. (3)For performance-based RSUs, represents the difference between the number of target shares at grant date and the number of shares vested at settlement, which can range from 0 to 200% of target depending on results over the applicable performance periods. (4)Represents amounts vested during the year, including the impact of performance adjustments for performance-based awards.
