[1] The fair value of our interest rate swaps, which are designated as fair value hedges, and our notes, due in 2014, 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 plan. The liability representing benefits accrued for plan participants is valued at the quoted market prices of the participants’ investment elections. The asset consists of mutual funds reflective of the partcipants’ investment selections and is valued at daily quoted market prices.
