On April 25, 2017, Murphy Oil USA, Inc., our primary operating subsidiary, issued $300 million of 5.625% Senior Notes due 2027 (the "2027 Senior Notes") under its existing shelf registration statement. The 2027 Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the 2027 Senior Notes contains restrictive covenants that limit, among other things, the ability of Murphy USA, Murphy Oil USA, Inc. and the restricted subsidiaries to incur additional indebtedness or liens, dispose of assets, make certain restricted payments or investments, enter into transactions with affiliates or merge with or into other entities.
On September 13, 2019, Murphy Oil USA, Inc., issued $500 million of 4.75% Senior Notes due 2029 (the “2029 Senior Notes”). The net proceeds from the issuance of the 2029 Senior Notes were used to fund, in part, the tender offer and redemption of the $500 million aggregate principal amount of its senior notes due 2023. The 2029 Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the 2029 Senior Notes contains restrictive covenants that are essentially identical to the covenants for the 2027 Senior Notes.
The 2027 and 2029 Senior Notes and the guarantees rank equally with all of our and the guarantors’ existing and future senior unsecured indebtedness and effectively junior to our and the guarantors’ existing and future secured indebtedness (including indebtedness with respect to the credit facilities) to the extent of the value of the assets securing such indebtedness. The 2027 and 2029 Senior Notes are structurally subordinated to all of the existing and future third-party liabilities, including trade payables, of our existing and future subsidiaries that do not guarantee the notes.
Credit Facilities and Term Loan
In August 2019, we amended and extended our existing credit agreement. The maturity date of the agreement was extended to August 2024. The credit agreement provides for a committed $325 million asset-based loan (ABL) facility (with availability subject to the borrowing base described below) and a $250.0 million term loan facility. It also provides for a $150 million uncommitted incremental facility. On August 27, 2019, Murphy Oil USA, Inc. borrowed $200 million under the term loan facility that has a -year term and prepaid the remaining balance of the prior term loan of $57 million, and on December 31, 2019, we borrowed the additional $50 million term loan. At September 30, 2020 and December 31, 2019, the current outstanding principal balance was $225 million and $250.0 million, respectively. The term loan is due August 2023 and requires quarterly principal payments of $12.5 million which began April 1, 2020. As of September 30, 2020, we have zero outstanding under our ABL facility.
The borrowing base is, at any time of determination, the amount (net of reserves) equal to the sum of:
• 100% of eligible cash at such time, plus
• 90% of eligible credit card receivables at such time, plus
• 90% of eligible investment grade accounts, plus
• 85% of eligible other accounts, plus
• 80% of eligible midstream refined products inventory at such time, plus
• 75% of eligible retail refined products inventory at such time, plus
the lesser of (i) 70% of the average cost of eligible retail merchandise inventory at such time and (ii) 85% of the net orderly liquidation value of eligible retail merchandise inventory at such time.
The ABL facility includes a $100 million sublimit for the issuance of letters of credit. Letters of credit issued under the ABL facility reduce availability under the ABL facility.
Interest payable on the credit facilities is based on either:
•the London interbank offered rate, adjusted for statutory reserve requirements (the “Adjusted LIBO Rate”);
•the Alternate Base Rate, which is defined as the highest of (a) the prime rate, (b) the greater of the federal funds effective rate and the overnight bank funding rate determined by the Federal Reserve Bank of New York from time to time plus 0.50% per annum and (c) the one-month Adjusted LIBO Rate plus 1.00% per annum,
plus, (A) in the case of Adjusted LIBO Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 1.50% to 2.00% per annum depending on a total debt to EBITDA ratio under the ABL facility or (ii) with respect to the term loan facility, spreads ranging from 2.50% to 2.75% per annum depending on a total debt to EBITDA ratio and (B) in the case of Alternate Base Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 0.50% to 1.00% per annum depending on a total debt to EBITDA ratio or (ii) with respect to the term loan facility, spreads ranging from 1.50% to 1.75% per annum depending on a total debt to EBITDA ratio.
The interest rate period with respect to the Adjusted LIBO Rate interest rate option can be set at , , , or six months as selected by us in accordance with the terms of the credit agreement.
The credit agreement contains certain covenants that limit, among other things, the ability of us and our subsidiaries to incur additional indebtedness or liens, to make certain investments, to enter into sale-leaseback transactions, to make certain restricted payments, to enter into consolidations, mergers or sales of material assets and other fundamental changes, to transact with affiliates, to enter into agreements restricting the ability of subsidiaries to incur liens or pay dividends, or to make certain accounting changes. In addition, the credit agreement requires us to maintain a minimum fixed charge coverage ratio of 1.0 to 1.0 when availability for at least consecutive business days is less than the greater of (a) 17.5% of the lesser of the aggregate ABL facility commitments and the borrowing base and (b) $70 million (including as of the most recent fiscal quarter end on the first date when availability is less than such amount), as well as a maximum secured total debt to EBITDA ratio of 4.5 to 1.0 at any time when term facility commitments or term loans are outstanding. As of September 30, 2020, our fixed charge coverage ratio was 1.14, and we had $197.3 million of availability under the ABL facility at that date. Our secured debt to EBITDA ratio as of September 30, 2020 was 0.32 to 1.0.
The credit agreement contains restrictions on certain payments, including dividends, when availability under the credit agreement is less than or equal to the greater of $100 million and 25% of the lesser of the revolving commitments and the borrowing base and our fixed charge coverage ratio is less than 1.0 to 1.0 (unless availability under the credit agreement is greater than $100 million and 40% of the lesser of the revolving commitments and the borrowing base). As of September 30, 2020, our ability to make restricted payments was not limited as our fixed charge coverage ratio was greater than 1.0 to 1.0, at 1.14. All obligations under the credit agreement are guaranteed by Murphy USA and the subsidiary guarantors party thereto, and all obligations under the credit agreement, including the guarantees of those obligations, are secured by certain assets of Murphy USA, Murphy Oil USA, Inc. and the guarantors party thereto.
