1	Common	Common Stock	2022-03-14	F	D	9,710	$118.51	125,591	D	—	—	(F2) The Original Form 4 is further amended to disclose that 9,710 shares of common stock were sold to cover tax withholding obligations arising from the award. The Original Form 4 did not report the sale to cover tax withholding obligations because the number of shares to be sold was not known at the time of filing.
2	Common	Common Stock	2022-02-18	A	A	24,461	$0.00	135,301	D	—	—	(F1) Due to a rounding error, discovered on March 15, 2022, the original Form 4 filed on behalf of the Reporting Person on February 18, 2022 (the 'Original Form 4') reported the vesting of 24,462 shares of common stock. This Form 4/A amends that filing to reflect a vesting of 24,461 shares of common stock. As previously reported, these shares of common stock vested upon the determination by the Compensation Committee of the Issuer's Board of Directors of the satisfaction of performance criteria underlying an award of performance stock units granted to the Reporting Person on February 15, 2019 under the terms of the Issuer's 2013 Omnibus Incentive Plan.
