Explanation of responses
- F1Each deferred stock unit ("DSU") represents a contingent right to receive one share of the Issuer's Common Stock.
- F2As part of the Company's non-employee director compensation program, the reporting person elected to receive their annual non-employee director equity compensation in the form of DSUs under the Issuer's 2020 Omnibus Incentive Compensation Plan and pursuant to a prior election under the Company's Deferred Compensation Plan for Non-Employee Directors. The DSUs were credited on a one-for-one basis relative to the award of shares of the Issuer's Common Stock.
- F3The DSUs are fully vested when granted and will be settled in shares of the Issuer's Common Stock following the reporting person's separation from service, disability, or death.
