Explanation of Responses:

( 1 )The shares vesting were awarded as restricted performance shares in February 2019 as reported in the Form 4 filing on February 14, 2019. This filing states that 50% of the restricted performance shares will vest at the end of the Performance Period if the Company is in the top 50th percentile of Return on Invested Capital (ROIC) among the Bloomberg Peer Group (BPG), 100% of the award will vest if the Company is in the top 75th ROIC percentile of the BPG and 150% of the award will vest if the Company is the top performing company of the BPG. The Company was the top performing ROIC company as of the end of the performance period and as such the performance criteria and all requirements for full vesting have been met and thus the shares granted in February 2019 vested on December 31, 2021, at the conclusion of the performance period.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
