[1] | We did not have any transfers in or out of Level 1, 2 or 3.
[2] | We entered into interest rate swaps to reduce our exposure to rising interest rates on our variable rate debt. The fair values of our interest rate swaps are based upon Level 2 inputs which include valuation models as reported by our counterparties. The key inputs for the valuation models are quoted market prices, discount rates and forward yield curves.
[3] | We maintain an unfunded defined contribution plan for key executives and other members of management. The fair value of this obligation is based on the closing market prices of the participants’ elected investments.
