Explanation of Responses:	
(1) 	Represents performance-based restricted stock units ("PSUs") and corresponding dividend equivalents accrued to the Reporting Person, under the 2013 Long Term Incentive Plan (the "Plan") that have vested and settled in shares of the Company's stock. Pursuant to the terms of the PSUs the total includes 159.00% of the original award.	
(2) 	Shares withheld for taxes on PSU vesting.	
(3) 	The original Form 4, filed on February 12, 2021, is being amended by this Form 4 amendment solely to correct an administrative error which misreported the number of performance stock units ("PSUs") and corresponding dividend equivalents. As a result of this administrative error, the number of PSUs and corresponding dividend equivalent units vested and settled reflects a decrease by 6 shares.	
(4) 	Reflects an award granted under the Plan.	
(5) 	These Securities generally do not carry a Conversion Price, Exercisable Date, or Expiration Date.	
(6) 	Reflects dividend equivalent units accrued on PSUs granted to the Reporting Person under the Plan. Each dividend equivalent unit reflects the right to receive common stock, subject to the terms and conditions (including vesting and settlement terms) applicable to the corresponding PSU.
