Explanation of Responses:
(1)	Restricted stock units represent the right to receive shares of common stock on a one-for-one basis and may be settled in cash or in shares of common stock.
(2)	Represents previously granted performance share units for which the performance criteria for the three-year performance period from January 1, 2017 through December 31, 2019 have been satisfied.
(3)	On March 6, 2019, the reporting person was granted performance share units for which the performance criteria for the one-year performance period from January 1, 2019 through December 31, 2019 have been satisfied. All of the restricted stock units reported here are subject to vesting based on the continued service of the reporting person through March 6, 2022. If the Company's total shareholder return over the three-year period of January 1, 2019 through December 31, 2021 is negative, then the cumulative number of units that may vest for such three-year period will be capped at 100% of the target number. (This Form 4 amendment is being filed to correct footnote 3 in the original filing, which should be disregarded).
