Senior Secured Term Loan B: We have a Senior Secured Term Loan B (the “Term Loan”) with an original principal amount of $400 million, which amortizes in equal quarterly installments of 1% per year with the balance payable in September 2024, when the facility matures. The Term Loan has an applicable interest rate margin of 300 basis points in the case of loans incurring interest based on LIBOR, and 200 basis points in the case of loans incurring interest based on the base rate. The Term Loan allows for incremental increases in facility size by up to an aggregate of $200 million, plus an additional amount such that the Company’s first lien leverage ratio (as defined under the Term Loan) would not exceed 4.00 to 1.00. MRC Global (US) Inc. is the borrower under this facility, which is guaranteed by MRC Global Inc. as well as all of its wholly owned U.S. subsidiaries. In addition, it is secured by a second lien on the assets securing our Global ABL Facility, defined below, (which includes accounts receivable and inventory) and a first lien on substantially all of the other assets of MRC Global Inc. and those of its U.S. subsidiaries, as well as a pledge of all of the capital stock of our domestic subsidiaries and 65% of the capital stock of first tier, non-U.S. subsidiaries. We are required to repay the Term Loan with certain asset sales and insurance proceeds. In addition, on an annual basis, we are required to repay an amount equal to 50% of excess cash flow, as defined in the Term Loan, reducing to 25% if our first lien leverage ratio is no more than 2.75 to 1.00. No payment of excess cash flow is required if the first lien leverage ratio is less than or equal 2.50 to 1.00. In addition, the Term Loan contains a number of customary restrictive covenants.

In March 2019, we purchased and retired $3 million of the outstanding interests in the Term Loan at a cost of $2 million. We recognized a gain of $1 million on the extinguishment of the debt in the three months ended March 31, 2020.

Global ABL Facility: We have an $800 million multi-currency asset-based revolving credit (the “Global ABL Facility”) that matures in September 2022. This facility is comprised of revolver commitments of $675 million in the United States, $65 million in Canada, $18 million in Norway, $15 million in Australia, $13 million in the Netherlands, $7 million in the United Kingdom and $7 million in Belgium. It contains an accordion feature that allows us to increase the principal amount of the facility by up to $200 million, subject to securing additional lender commitments. MRC Global Inc. and each of its current and future wholly owned material U.S. subsidiaries guarantee the obligations of our borrower subsidiaries under the Global ABL Facility. Additionally, each of our non-U.S. borrower subsidiaries guarantees the obligations of our other non-U.S. borrower subsidiaries under the Global ABL Facility. Outstanding obligations are generally secured by a first priority security interest in accounts receivable and inventory. Availability is dependent on a borrowing base comprised of a percentage of eligible accounts receivable and inventory which is subject to redetermination from time to time. Excess Availability, as defined under our Global ABL Facility and adjusted for the pro forma effect of an inventory appraisal completed in April 2020, was $437 million as of March 31, 2020.
