Interest Rate Swap Agreements

We have entered into interest rate swap agreements to manage our exposure to fluctuations in interest rates. These swap agreements involve the exchange of fixed and variable rate interest payments between us and our counterparties based on common notional principal amounts and maturity dates.

Pay-fixed

interest rate swaps effectively convert variable rate obligations to fixed interest rate obligations. The interest payments under these agreements are settled on a net basis. The net interest payments, based on the notional amounts in these agreements, generally match the timing of the related liabilities for the interest rate swap agreements which have been designated as cash flow hedges. The notional amounts of the swap agreements represent amounts used to calculate the exchange of cash flows and are not our assets or liabilities. Our credit risk related to these agreements is considered low because the swap agreements are with creditworthy financial institutions.

The following table sets forth our interest rate swap agreements, which have been designated as cash flow hedges, at March 31, 2020 (dollars in millions):


	Notional Amount		Maturity Date		Fair Value
Pay-fixed interest rate swaps	$	2,000		December 2021	$	(41	)
Pay-fixed interest rate swaps		500		December 2022		(24	)

During the next 12 months, we estimate $31 million will be reclassified from other comprehensive income (“OCI”) and will be included in interest expense.

Derivatives in Cash Flow Hedging Relationships	Amount of Loss Recognized in OCI on Derivatives, Net of Tax		Location of Gain Reclassified from Accumulated OCI into Operations		Amount of Gain Reclassified from Accumulated OCI into Operations
Interest rate swaps	$	46		Interest expense	$	1

Credit-risk-related Contingent Features

We have agreements with each of our derivative counterparties that contain a provision where we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of March 31, 2020, we have not been required to post any collateral related to these agreements. If we had breached these provisions at March 31, 2020, we would have been required to settle our obligations under the agreements at their aggregate, estimated termination value of $66 million.
