Derivative Instruments and Hedging Activities Disclosure [Abstract] |
DERIVATIVES | DERIVATIVES From time to time, we enter into interest rate swap and cap agreements to manage our fixed and variable interest rate exposure and to better match 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 or forecasted debt obligations as well as our offsetting hedge positions. This risk management process involves the use of analytical techniques, including cash flow sensitivity analysis, to estimate the expected impact of changes in interest rates on our future cash flows. As of December 31, 2012, we have interest rate swaps outstanding which are designated as fair value hedges whereby we receive fixed interest rate payments in exchange for making variable interest rate payments. The differential to be paid or received is accrued and recognized as interest expense. The following table provides a detail of the swaps outstanding and the related hedged items as of December 31, 2012:
|  |  |  | Face value of medium-term notes |  | Aggregate notional amount of interest rate swaps |  |  |  | Weighted-average variable interest rate on hedged debt as of December 31,
Issuance date |  | Maturity date |  |  |  | Fixed interest rate |  | 2012 |  | 2011
|  |  |  | (Dollars in thousands) |  |  |  |  |  |
May 2011 |  | June 2017 |  | $350,000 |  | $150,000 |  | 3.50% |  | 1.62% |  | 1.84%
February 2011 |  | March 2015 |  | $350,000 |  | $150,000 |  | 3.15% |  | 1.66% |  | 1.43%
February 2008 |  | March 2013 |  | $250,000 |  | $250,000 |  | 6.00% |  | 2.84% |  | 2.61%
Changes in the fair value of our interest rate swaps are offset by changes in the fair value of the debt instrument. Accordingly, there is no ineffectiveness related to the interest rate swaps. The location and amount of gains (losses) on derivative instruments and related hedged items reported in the Consolidated Statements of Earnings were as follows:
