Revolving Credit Facility. At September 30, 2017, there were no borrowings outstanding and $36 million in letters of credit issued under FCX’s revolving credit facility, resulting in availability of approximately $3.5 billion, of which approximately $1.5 billion could be used for additional letters of credit.

Senior Notes Issued by FCX. In March 2017, FCX’s 2.15% Senior Notes matured, and the $500 million outstanding principal balance was repaid.

Cerro Verde Credit Facility and Shareholder Loans. In June 2017, Cerro Verde’s credit facility was amended to increase the commitment by $225 million to $1.5 billion, modify the amortization schedule and to extend the maturity date to June 19, 2022. The amended credit facility amortizes in four installments, with $225 million due on December 31, 2020, $225 million due on June 30, 2021, $525 million due on December 31, 2021, and the remaining balance due on the maturity date of June 19, 2022. All other terms, including the interest rates, remain the same. The interest rate on Cerro Verde's credit facility was 3.14 percent at September 30, 2017. Cerro Verde used proceeds from its amended credit facility plus available cash to repay the balance of its shareholder loans in June 2017. Refer to Note 8 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.

Exchanges and Early Extinguishment of Debt. During third-quarter2017, FCX redeemed in full certain senior notes. A summary of these early debt extinguishments follows (in millions):

	Principal Amount		Net Adjustments		Book Value		Redemption Value		Gain
FCX 6.125% Senior Notes due 2019	$	179	$	5	$	184	$	182	$	2
FM O&G 6.125% Senior Notes due 2019	58		2		60		59		1

	$	543	$	23	$	566	$	555	$	11

Partially offsetting the $11 million gain on early extinguishment of certain senior notes was a net loss of $3 million, primarily associated with the modification of Cerro Verde’s credit facility in second-quarter 2017.

During the second and third quarters of 2016, FCX redeemed certain senior notes in exchange for its common stock, which resulted in gains of $15 million in third-quarter2016 and $54 million for the first nine months of 2016. Partially offsetting the gains were $3 million in losses, primarily associated with the modification of FCX’s revolving credit facility in first-quarter 2016. Refer to Notes 8 and 10 of FCX’s annual report on Form 10-K for the year ended December 31, 2016, for further discussion.
