DEBT AND FINANCING COSTS

The following table presents the carrying amounts and estimated fair values of the Company’s outstanding debt as of September 30, 2017 and December 31, 2016:



	September 30, 2017				December 31, 2016
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(In millions)
Commercial paper and committed bank facilities	$	—	$	—	$	—	$	—
Notes and debentures	8,483		9,094		8,544		9,183
Total Debt	$	8,483	$	9,094	$	8,544	$	9,183

The Company’s debt is recorded at the carrying amount, net of related unamortized discount and debt issuance costs, on its consolidated balance sheet. When recorded, the carrying amount of the Company’s commercial paper, committed bank facilities, and uncommitted bank lines approximates fair value because the interest rates are variable and reflective of market rates. Apache uses a market approach to determine the fair value of its notes and debentures using estimates provided by an independent investment financial data services firm (a Level 2 fair value measurement).

The following table presents the carrying value of the Company’s debt as of September 30, 2017 and December 31, 2016:



	September 30, 2017			December 31, 2016
	(In millions)
Debt before unamortized discount and debt issuance costs	$	8,580		$	8,650
Unamortized discount	(48		)	(50		)
Debt issuance costs	(49		)	(56		)
Total debt	8,483			8,544
Current maturities	(550		)	—
Long-term debt	$	7,933		$	8,544

As of September 30, 2017, current debt included $150 million of 7.0% senior notes due February 1, 2018 and $400 million of 6.9% senior notes due September 15, 2018.

As of September 30, 2017, the Company had a revolving credit facility that matures in June 2020, subject to Apache’s two one-year extension options. The facility provides for aggregate commitments of $3.5 billion (including a $750 million letter of credit subfacility), with rights to increase commitments up to an aggregate $4.5 billion. Proceeds from borrowings may be used for general corporate purposes. Apache’s available borrowing capacity under this facility supports its $3.5 billion commercial paper program. The commercial paper program, which is subject to market availability, facilitates Apache borrowing funds for up to 270 days at competitive interest rates. As of September 30, 2017, the Company had no commercial paper or borrowings under committed bank facilities or uncommitted bank lines outstanding.

As of September 30, 2017, the Company had a letter of credit facility, which provides for £900 million in commitments and rights to increase commitments to £1.075 billion. This facility matures in February 2020. The facility is available for letters of credit and loans to cash collateralize letters of credit or obligations to provide letters of credit, in each case, to the extent letters of credit are unavailable under the facility. As of September 30, 2017, three letters of credit aggregating approximately £147.5 million and no borrowings were outstanding under this facility.

In November 2016, the Company initiated a program to purchase in the open market up to $250 million in aggregate principal amount of senior notes issued under its indentures. In the fourth quarter of 2016, the Company purchased and canceled $181 million aggregate principal amount of its senior notes through open market repurchases for $182 million in cash, including accrued interest and $0.5 million of premium.

In January 2017, the Company purchased and canceled an additional $69 million aggregate principal amount of senior notes for $71 million in cash, including accrued interest and $1 million of premium, which completed the open market repurchase program. These repurchases resulted in a $1 million net loss on extinguishment of debt, which is included in “Financing costs, net” in the Company’s consolidated statement of operations. The net loss includes an acceleration of related discount and deferred financing costs.

In August 2017, the Company assumed the obligations of Apache Finance Canada Corporation (AFCC) in respect of $300 million 7.75% notes due in 2029 which AFCC issued and the Company guaranteed pursuant to the governing indenture. The assumption was permitted by the indenture and effected pursuant to a supplemental indenture thereto. As a result of the assumption, the Company is the obligor under the notes and indenture, and AFCC is released from its obligations thereunder. The $300 million 7.75% notes historically have been included in the Company’s long-term debt; accordingly, the assumption did not change the Company’s long-term debt or total debt.
