Interest Rate Derivatives – Cash Flow Hedges

From time to time, the Company has entered into various interest rate lock agreements and forward starting interest rate swap agreements to hedge part of the Company's interest rate exposure associated with the variability in future cash flows attributable to changes in interest rates.

In May 2016, the Company entered into interest rate lock agreements with several financial institutions for a total notional amount of $250 million which were accounted for as cash flow hedges. These agreements were entered into to hedge a portion of the Company’s interest rate exposure associated with variability in future cash flows attributable to changes in the ten-year treasury rates related to the planned issuance of the 2016 Senior Notes. In connection with the issuance of the 2016 Senior Notes, these agreements were settled, and the Company paid $1 million. These losses are deferred in stockholders’ equity, net of taxes, as a component of accumulated other comprehensive loss, and amortized as an adjustment to interest expense, net over the term of the respective senior notes.

The total net loss, net of taxes, recognized in accumulated other comprehensive loss, related to the Company's cash flow hedges was $9 million as of both December 31, 2018 and 2017. The net amount of deferred losses on cash flow hedges that is expected to be reclassified from accumulated other comprehensive loss into interest expense, net within the next twelve months is $3 million.

Interest Rate Derivatives – Fair Value Hedges

The Company maintains various fixed-to-variable interest rate swaps to convert a portion of the Company's long-term debt into variable interest rate debt. A summary of the notional amounts of these interest rate swaps as of December 31, 2018 and 2017 was as follows:



	Notional Amount
Debt Instrument	2018		2017

4.25% Senior Notes due April 2024	250		250
3.50% Senior Notes due March 2025	600		600
3.45% Senior Notes due June 2026	350		350
	$	1,200	$	1,200

The fixed-to-variable interest rate swap agreements in the table above have variable interest rates ranging from one-month LIBOR plus 2.2% to one-month LIBOR plus 3.0%.

As of December 31, 2015, the Company had entered into various fixed-to-variable interest rate swap agreements with an aggregate notional amount of $1.2 billion. In July 2016, the Company terminated those interest rate swaps agreements. As a result of the termination, the Company received proceeds of $60 million, which included $6 million of accrued interest. The remaining basis adjustment on the respective debt obligation of $54 million will be amortized as a reduction of interest expense over the remaining terms of the hedged debt instrument. Immediately after the termination of these interest rate swaps, the Company entered into new fixed-to-variable interest rate swap agreements, which are reflected in the table above.

As of December 31, 2018 and 2017, the following amounts were recorded on the consolidated balance sheet related to cumulative basis adjustments for fair value hedges included in the carrying amount of long-term debt:



	Carrying Amount of Hedged Long-Term Debt		Hedge Accounting Basis Adjustment (a)			Carrying Amount of Hedged Long-Term Debt		Hedge Accounting Basis Adjustment (a)
Balance Sheet Classification	December 31, 2018		December 31, 2018			December 31, 2017		December 31, 2017
Long-term debt	$	1,125	$	(53	)	$	1,132	$	(33	)

(a) The balance includes $40 million and $56 million of remaining unamortized hedging adjustment on a discontinued relationship as of December 31, 2018 and 2017, respectively.

The following table presents the effect of fair value hedge accounting on the statement of operations for the years ended December 31, 2018 and 2017, respectively:

Interest Rate Derivatives - Economic Hedges

In March 2016, in connection with the retirement of debt (see Note 14), the Company entered into reverse interest rate lock agreements with several financial institutions which were not designated for hedge accounting. The Company entered into these agreements to hedge the variability in cash flows associated with $75 million of the $200 million principal amount of debt that was retired in the first quarter of 2016. These agreements were settled during the first quarter of 2016 resulting in a gain of $1 million which was recognized in other (expense) income, net.
