Derivative Instruments
The Company utilizes derivative financial instruments to manage interest rate risk. The Company does not use derivative financial instruments for trading or speculative purposes, nor does it use leveraged financial instruments. The Company reports its derivative instruments separately as assets and liabilities unless a legal right of set-off exists under a master netting agreement enforceable by law. The Company’s derivative instruments are recorded at their fair value, and are included in other long-term assets, other long-term liabilities and other liabilities in the Condensed Consolidated Balance Sheets.
