[1] On September 30, 2016, the Company negotiated amendments to the terms of these interest rate swap agreements (the "Existing Swap Agreements," 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 are recognized in Interest expense over the remaining life of the Amended Swaps.
