Credit Facility—The Company has a $160.0 million asset-based senior secured revolving credit facility (“credit facility”). Borrowing availability under the credit facility is based on eligible accounts receivable, inventory and real estate. The real estate component of the borrowing base amortizes monthly over 12.5 years on a straight-line basis. Borrowings under the credit facility are collateralized by substantially all of the Company’s assets and are subject to certain operating limitations applicable to a loan of this type, which, among other things, place limitations on indebtedness, liens, investments, mergers and acquisitions, dispositions of assets, cash dividends and transactions with affiliates. The credit facility matures on May 28, 2019 and all amounts borrowed are due and payable on that date.

At December 31, 2016, under the credit facility, the Company had revolving credit borrowings of $52.2 million outstanding at a weighted average interest rate of 2.27% per annum, letters of credit outstanding totaling $3.0 million, primarily for health and workers’ compensation insurance, and $76.5 million of additional committed borrowing capacity. The Company pays an unused commitment fee of 0.25% per annum. In addition, the Company had $3.3 million of capital leases and other obligations outstanding at December 31, 2016.

The sole financial covenant in the credit facility is the minimum fixed charge coverage ratio (“FCCR”) of 1.05:1.00 and must be tested by the Company only if the excess borrowing availability falls below an amount in the range of $12.5 million to $20.0 million, depending on our borrowing base. FCCR must also be tested on a pro forma basis prior to consummation of certain significant business transactions outside our ordinary course of business, as defined in the agreement.

Maturities—At December 31, 2016, the aggregate scheduled maturities of debt were as follows (in millions):

2017	$	1.0
2018		0.9
2019		52.9
2020		0.4
2021		0.3
Total	$	55.5

The fair value of long-term debt, as calculated using the aggregate cash flows from principal and interest payments over the life of the debt, was approximately $52.2 million and $46.1 million at December 31, 2016 and 2015, respectively, based upon a discounted cash flow analysis using current market interest rates. The fair value measurement inputs for long-term debt are classified as Level 3 (unobservable inputs) in the valuation hierarchy.
