(1) The fair value of our interest rate swaps, designated as fair value hedges, and notes are based on the present value of expected future cash flows using zero coupon rates and are classified within Level 2 of the fair value hierarchy.


(2) We maintain deferred compensation plans that allow for certain management employees to defer the receipt of compensation (such as salary, incentive compensation and commissions) until a later date based on the terms of the plans. The liability representing benefits accrued for plan participants is valued at the quoted market prices of the participants’ investment elections.
