Explanation of responses
- F1These stock units were granted under the Issuer's Nonqualified Deferred Compensation Plan (the "Plan") and represent notional equity interests in the Issuer credited to the filing person's deferred compensation account. Each stock unit is the economic equivalent of one share of the Issuer's Common Stock. The Issuer matches 50% of any amounts invested in stock units, subject to vesting as set forth in the Plan. These stock units become payable, through the issuance of shares of the Issuer's Common Stock (or the cash equivalent thereof), on the date specified by the filing person, which can be no earlier than five years following the year of deferral associated with such stock units or, if earlier, six months after the date the filing person separates from service with the Issuer or the date of death of the filing person.
