	2017		2016
Variable-rate Accounts Receivable Facility with an interest rate of 2.15% at December 31, 2017	$	62.9	$	—

Short-term debt	$	105.4	$	19.2

The Company has a $100 million Accounts Receivable Facility that matures on November 30, 2018. The Company is exploring opportunities to refinance the facility prior to its maturity. Under the terms of the Accounts Receivable Facility, the Company sells, on an ongoing basis, certain domestic trade receivables to Timken Receivables Corporation, a wholly owned consolidated subsidiary that, in turn, uses the trade receivables to secure borrowings that are funded through a vehicle that issues commercial paper in the short-term market. Borrowings under the Accounts Receivable Facility are limited to certain borrowing base limitations. These limitations reduced the availability of the Accounts Receivable Facility to $82.3 million at December 31, 2017. As of December 31, 2017, there were outstanding borrowings of $62.9 million under the Accounts Receivable Facility, which reduced the availability under this facility to $19.4 million. The cost of this facility, which is the prevailing commercial paper rate plus program fees, is considered a financing cost and is included in interest expense in the Consolidated Statements of Income. The outstanding balance under the Accounts Receivable Facility was classified as short term or long term in accordance with the terms of the agreement. In 2016, the classification of the outstanding balance reflected the Company's expectations relative to the minimum borrowing base. The yield rate was 2.15%, 1.65% and 1.05%, at December 31, 2017, 2016 and 2015, respectively.

The lines of credit for certain of the Company’s foreign subsidiaries provide for short-term borrowings up to $288.9 million in the aggregate. Most of these lines of credit are uncommitted. At December 31, 2017, the Company’s foreign subsidiaries had borrowings outstanding of $42.5 million and guarantees of $0.2 million, which reduced the aggregate availability under these facilities to $246.2 million. The weighted-average interest rate on these lines of credit during the year were 0.7%, 0.7% and 1.1% in 2017, 2016 and 2015, respectively. The weighted-average interest rate on lines of credit outstanding at December 31, 2017 and 2016 was 0.41% and 0.50%, respectively. The decrease in the weighted-average interest rate was primarily due to increased borrowings in the United States at a lower rate.
