[1] We entered into interest rate swaps to reduce our exposure to rising interest rates on our variable debt. The fair values of our interest rate swaps are based upon valuation models as reported by our counterparties.

[2] We maintain an unfunded defined contribution plan for key executives and other members of management excluded from participation in our qualified savings plan. The fair value of this obligation is based on the closing market prices of the participants' elected investments.
