Explanation of Responses:

Id Content
F1 Represents the number of shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of Performance Stock Units ("PSUs"). These sales are mandated by the Issuer's election under its equity incentive plans to require the satisfaction of a tax withholding obligation to be funded by a "sell to cover" transaction and do not represent discretionary trades by the Reporting Person.
