[1] On March 25, 2013, the Company negotiated amendments to the terms of these interest rate swap agreements, which were entered into in March 2012 (the "Existing Swap Agreements") to coincide with the Repricing (as amended, the “Amended Swaps”). The Amended Swaps are held with the same counterparties as the Existing Swap Agreements. Upon entering into the Amended Swaps, the Company simultaneously dedesignated the Existing Swap Agreements and redesignated the Amended Swaps as cash flow hedges for the underlying change in the swap terms. The amounts previously recognized in Accumulated other comprehensive income (loss) relating to the dedesignation will be recognized in Interest expense over the remaining life of the Amended Swaps.
