Derivative Instruments [Abstract] |
Derivative Instruments | NOTE 7: DERIVATIVE INSTRUMENTS In May 2009, we entered into a forward interest rate swap with a notional amount of $100.0 million that qualifies as a cash flow hedge. We enter into interest rate swaps to manage our exposure to variable rate interest risk. We do not purchase derivatives for speculation. We record our cash flow hedges at fair value in accordance with GAAP, based on various discounted cash flow methodologies and observable inputs. We record the effective portion of changes in fair value of cash flow hedges in other comprehensive income. This change in fair value of cash flow hedges is the only activity in other comprehensive income (loss) during the periods presented in our consolidated financial statements. We record the ineffective portion of changes in fair value of cash flow hedges in earnings in the period affected. We assess the effectiveness of our cash flow hedges both at inception and on an ongoing basis. We deemed the hedges to be effective for the 2011 and 2010 Quarters and Periods, as applicable. The fair value and balance sheet locations of the interest rate swaps as of September 30, 2011 and December 31, 2010 are as follows (in millions):
|  | September 30, 2011 |  |  | December 31, 2010 |
|  | Fair Value |  |  | Fair Value |
Accounts payable and other liabilities |  | $ | 0.2 |  |  | $ | 1.5 |
The interest rate swap has been effective since inception. The gain or loss on the effective swaps is recognized in other comprehensive income, as follows (in millions):
|  | Quarter Ended September 30, |  |  | Period Ended September 30, |
|  | 2011 |  |  | 2010 |  |  | 2011 |  |  | 2010 |
|  | Fair Value |  |  | Fair Value |  |  | Fair Value |  |  | Fair Value |
Change in other comprehensive income (loss) |  | $ | 0.5 |  |  | $ | — |  |  | $ | 1.3 |  |  | $ | (0.1 | )
Derivative instruments expose us to credit risk in the event of non-performance by the counterparty under the terms of the interest rate hedge agreement. We believe that we minimize our credit risk on these transactions by dealing with major, creditworthy financial institutions. As part of our on-going control procedures, we monitor the credit ratings of counterparties and our exposure to any single entity, thus minimizing our credit risk concentration.
