Id	Content
F1	The reported transaction represents the vesting of 2,528 unvested Restricted Stock Units previously included in Table II. The reporting person elected to defer delivery of the shares of Common Stock otherwise deliverable to the reported person upon vesting and, instead, was credited with an equivalent number of phantom shares under the Company's deferred compensation plan for non-employee directors. Each phantom share is the economic equivalent of one share of Common Stock. The shares of phantom stock become payable in cash or Common Stock upon the reporting person's termination of service and may be transferred by the reporting person into an alternative investment account at any time.
F2	The reported transaction represents the grant of 3,465 Restricted Stock Units that were fully vested at grant. Each Restricted Stock Unit represented a contingent right to receive one share of Common Stock. The reporting person elected to defer delivery of the shares of Common Stock otherwise deliverable to the reported person upon vesting and, instead, was credited with an equivalent number of phantom shares under the Company's deferred compensation plan for non-employee directors. Each phantom share is the economic equivalent of one share of Common Stock. The shares of phantom stock become payable in cash or Common Stock upon the reporting person's termination of service and may be transferred by the reporting person into an alternative investment account at any time.
