Common Share Repurchases COMMON SHARE REPURCHASES
 
During the three months ended March 31, 2023, the Company repurchased 2.2 million common shares under its share repurchase authorizations for total cost of $400 million. The average cost per share repurchased was $183.26.  In addition, the Company acquired 0.3 million common shares for a total cost of $62 million during the three months ended March 31, 2023 that were not part of its publicly announced share repurchase authorizations.  These shares consisted of shares retained to cover payroll withholding taxes in connection with the vesting of restricted stock unit awards and performance share awards, and shares used by employees to cover the price of certain stock options that were exercised. Included in the cost of treasury stock acquired pursuant to common share repurchases is the 1% excise tax imposed as part of the Inflation Reduction Act. On April 19, 2023, the Board of Directors approved a share repurchase authorization that added an additional $5.0 billion of repurchase capacity to the $1.60 billion of capacity remaining at March 31, 2023.
