Explanation of Responses:

1. Each Restricted Stock Right ("RSR") represents a contingent right to receive an equivalent number of shares of Company common stock, or, at the discretion of the Company's Compensation Committee, cash or a combination of cash and Company common stock. The RSRs were granted under the 2022 Long-Term Incentive Stock Plan ("LTISP") and vest ratably in three equal installments upon each of the first, second, and third anniversaries of the grant date.

2. The amount acquired represents dividend equivalent rights on the RSRs, which are credited following payment of the Company's quarterly cash dividend. Pursuant to the LTISP, the number of dividend equivalent rights acquired is calculated by dividing the aggregate amount of the dividend paid on the total number of RSRs held by the reporting person by the closing price of a share of Company common stock on the dividend payment date.
