Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES From time to time, we enter into interest rate derivative contracts to manage our fixed and variable interest rate exposure and to better align the repricing of debt instruments to that of our portfolio of assets. We assess the risk that changes in interest rates will have either on the fair value of debt obligations or on the amount of future interest payments by monitoring changes in interest rate exposures and by evaluating hedging opportunities. We regularly monitor interest rate risk attributable to both our outstanding and forecasted debt obligations as well as any offsetting hedge positions. This risk management process involves the use of analytical techniques, including cash flow sensitivity analyses, to estimate the expected impact of changes in interest rates on our future cash flows. As of September 30, 2017, we had interest rate swaps outstanding, which are designated as fair value hedges for certain debt obligations, with a total notional value of $825 million and maturities through 2022. Interest rate swaps are measured at fair value on a recurring basis using Level 2 fair value inputs. The fair value amounts of the interest rate swaps are recorded in "Direct financing leases and other assets" and "Other non-current liabilities" in our Consolidated Condensed Balance Sheets. As of September 30, 2017, these amounts are not material to our consolidated financial position or results of operations and have not changed significantly from the amounts reported at December 31, 2016. Changes in the fair value of our interest rate swaps were offset by changes in the fair value of the hedged debt instruments. Accordingly, there was no ineffectiveness related to the interest rate swaps.
