NOTE 8—LONG-TERM DEBT

On May 17, 2017, the Company entered into a Fifth Amended and Restated Business Loan and Security Agreement with a syndication of 11 commercial banks (the “Credit Facility”). The Credit Facility: (i) includes modifications to the Company’s Fourth Amended and Restated Business Loan and Security Agreement, (ii) matures on May 17, 2022, (iii) increases the borrowing ceiling up to $600.0 million without a borrowing base requirement, taking into account financial, performance-based limitations, and (iv) provides for an “accordion,” which permits additional revolving credit commitments of up to $300.0 million, subject to lenders’ approval. While the modification of the Credit Facility did not increase the amount of outstanding, $106.0 million of funds from new syndicated borrowings was used to pay off or pay down borrowings from syndicate members prior to the loan modification and align the allocation of debt within the syndicate. These amounts were included within the “Advances from working capital facilities” and “Payments on working capital facilities” line items in the statement of cash flows for the year ended December 31, 2017.

The Company has the option to borrow funds under the Credit Facility at interest rates based on both LIBOR (1, 3, or 6 month rates) and the Base Rate, at its discretion, plus their applicable margins. Base Rates are fluctuating per annum rates of interest equal to the highest of (i) the Federal Funds Open Rate, plus 0.5%, (ii) the Prime Rate, and (iii) the daily LIBOR rate, plus a LIBOR Margin of between 1.00% and 2.00% based on our Leverage Ratio (as defined under the Credit Facility), 1.25% as of December 31, 2017. The interest accrued based on LIBOR rates is to be paid on the last business day of the interest period (1, 3, or 6 months), while interest accrued based on the Base Rates is to be paid in quarterly installments. The Credit Facility provides for letters of credit aggregating up to $60.0 million which reduce the funds available under the Credit Facility when issued. The Credit Facility is collateralized by substantially all of the assets of the Company and requires that the Company remain in compliance with certain financial and non-financial covenants. The financial covenants require, among other things, that the Company maintain at all times an Interest Coverage Ratio (as defined under the Credit Facility) of not less than 3.00 to 1.00 and a Leverage Ratio of not more than 3.75 to 1.00 (subject to adjustment, in certain circumstances) for each fiscal quarter. As of December 31, 2017, the Company was in compliance with its covenants under the Credit Facility.

The Credit Facility was subject to a commitment fee on the unused portion of the Credit Facility of between 0.13% and 0.25% per annum, based on our Leverage Ratio, 0.15% per annum at December 31, 2017 and 0.25% per annum at December 31, 2016.

As of December 31, 2017, the available borrowing capacity under the Credit Facility (excluding the accordion) was $390.0 million. Taking into account the financial and performance-based limitations, the available borrowing capacity (excluding the accordion) was $245.1 million as of December 31, 2017.
