SHORT-TERM BORROWINGS, LONG-TERM DEBT AND AVAILABLE CREDIT FACILITIES

The following tables summarize the company's short-term borrowings and capital lease obligations and long-term debt:



Short-term borrowings and capital lease obligations	Successor		Predecessor
(In millions)	December 31, 2017		December 31, 2016
Commercial paper	$	1,436	$	386
Other loans - various currencies	28		39
Long-term debt payable within one year	1,315		4
Total short-term borrowings and capital lease obligations	$	2,779	$	429

The estimated fair value of the company's short-term borrowings, including interest rate financial instruments, was determined using Level 2 inputs within the fair value hierarchy, as described in Note 1 and Note 19. Based on quoted market prices for the same or similar issues, or on current rates offered to the company for debt of the same remaining maturities, the fair value of the company's short-term borrowings and capital lease obligations was $2,780 million and $430 million at December 31, 2017 and 2016, respectively.

The weighted-average interest rate on short-term borrowings outstanding at December 31, 2017 and 2016 was 1.8 percent and 2.2 percent, respectively. The decrease in the interest rate for 2017 was primarily due to lower effective interest on long-term debt payable within one year.

Debt Offering

In May 2017, the company completed an underwritten public offering of $1,250 million of the company's 2.20 percent Notes due 2020 and $750 million of the company's Floating Rate Notes due 2020 (the "May 2017 Debt Offering"). The proceeds of this offering were used to make a discretionary pension contribution to the company's principal U.S. pension plan. See Note 16 for further discussion regarding this contribution.

Term Loan Facility

In March 2016, the company entered into a credit agreement that provides for a three-year, senior unsecured term loan facility in the aggregate principal amount of $4,500 million (the "Term Loan Facility") under which DuPont may make up to seven term loan borrowings and amounts repaid or prepaid are not available for subsequent borrowings. The facility was amended in 2017 to extend the date on which the commitment to lend terminates to July 27, 2018. The proceeds from the borrowings under the Term Loan Facility will be used for the company's general corporate purposes including debt repayment, working capital and funding a portion of DowDuPont's costs and expenses. The Term Loan Facility matures in March 2019 at which time all outstanding borrowings, including accrued but unpaid interest, become immediately due and payable. As of December 31, 2017, the company had made three term loan borrowings in an aggregate principal amount of $1,500 million and had unused commitments of $3,000 million under the Term Loan Facility.

Uncommitted Credit Facilities and Outstanding Letters of Credit

Unused bank credit lines on uncommitted credit facilities were approximately $731 million at December 31, 2017. These lines are available to support short-term liquidity needs and general corporate purposes including letters of credit. Outstanding letters of credit were $177 million at December 31, 2017. These letters of credit support commitments made in the ordinary course of business.
