Footnotes

F1: This reported acquisition of stock resulted from the Company's allocation of the reporting person's unvested account balance in the "Age 62 Plan," one of the Company's nonqualified deferred compensation plans, to an account tied to the value of the Company's common stock. Under the Age 62 Plan, the Company contributes to the plan on the participant's behalf, and awards deemed invested in the Company's common stock must be settled in shares of Company common stock. Participants do not vest in awards until they attain age 62, and do not have investment or voting control with respect to the investment vehicles in which their account balance is deemed invested. The reported shares of stock were allocated to the reporting person's account under the Age 62 Plan as of May 21, 2013.
