Derivative Instruments and Hedging Activities Disclosure [Abstract] |
5. Derivatives | 5. Derivatives We manage exposure to changes in market interest rates. Our use of derivative instruments is limited to highly effective interest rate swaps to hedge the risk of changes in cash flows (future interest payments) attributable to changes in LIBOR swap rates, the designated benchmark interest rate being hedged on certain of our LIBOR indexed variable rate debt and a variable rate operating lease. The interest rate swaps effectively fix our interest payments on certain LIBOR indexed variable rate debt. We monitor our positions and the credit ratings of our counterparties and do not currently anticipate non-performance by the counterparties. Interest rate swap agreements are not entered into for trading purposes.
