2018 Credit Facility
Contemporaneous with the close of the CR Permian acquisition on November 1, 2018, the Partnership entered into a credit agreement with its lenders and with Barclays Bank PLC, as administrative agent, for a term loan in an initial aggregate principal amount of $690.0 million with a tenor of seven years, maturing on November 3, 2025. Fixed principal payments equal to 0.25% of the initial principal amount are required to be paid quarterly. Interest is paid on the term loan periodically at a rate equal to 4.75% plus LIBOR (0% floor). The Partnership paid scheduled principal payments on this term loan of $6.9 million, $6.9 million and $3.5 million for the years ended December 31, 2021, 2020 and 2019, respectively. Additionally, throughout 2021, the Partnership voluntarily repurchased $25.9 million of outstanding term loan debt associated with the $690 million term loan on the open market. Similar open market repurchases totaling $7.5 million were made during the year ended December 31, 2020.
In addition, the Partnership entered into a revolving credit facility in an initial aggregate principal amount of $50.0 million with a tenor of five years, maturing on November 3, 2023. On January 16, 2020, the Partnership entered into an amendment to the revolving credit agreement that increased the revolving commitment in an aggregate principal amount of $10.0 million, thereby increasing the aggregate revolving credit commitments of all lenders to $60.0 million. Interest is paid on the revolver periodically at a rate equal to LIBOR plus the applicable margin based on our consolidated total leverage ratio, which is between 4.25% and 4.75%. Any unpaid interest and principal are due at maturity. The Partnership must pay quarterly commitment fees of 0.5% on the unused portion of the commitment, which commenced in September 2019. As of December 31, 2021 and 2020, there were no outstanding letters of credit under the revolving credit facility.
Our debt agreements contain various covenants or restriction provisions that, amongst other things limit or restrict the Partnership’s ability to incur certain liens on assets, property or revenue, engage in certain mergers, dissolutions, investments or acquisitions, incur indebtedness or guarantee debt, make certain dispositions, and enter into certain transactions with subsidiaries or affiliates that exceed a specified threshold. These agreements also contain defined financial covenants, including a debt service coverage ratio. As of December 31, 2021 and 2020, the Partnership was in compliance with all loan covenants.
2019 Credit Facility
On September 18, 2019, the Partnership entered into a credit agreement with its lenders for a term facility with an initial term commitment of $483.0 million and a conversion date term commitment of $30.2 million and a letter of credit facility up to $32.7 million. On the closing date, $232.1 million was drawn down on the term commitment and additional drawdowns totaling $250.9 million were borrowed over the subsequent months to fund the Partnership’s capital contributions to PHP. The tenor of the agreement is equal to the earlier of six and two-tenths years from the closing date, or four years after the term conversion date. The term conversion date is essentially the final completion date of the PHP pipeline project, which occurred on March 3, 2021. On March 3, 2021, all conditions of the term conversion were met, and the Partnership borrowed the additional $30.2 million associated with the conversion date term commitment, which was subsequently distributed to our equity sponsors. Given the establishment of the term conversion date, the maturity of the associated debt is due March 3, 2025 in accordance with the credit agreement. During the year ended December 31, 2021, the Partnership paid its first principal payments on this term loan totaling $33.8 million.
Fixed principal payments are required to be paid quarterly commencing with the first full quarter ending after the term conversion date, which was June 30, 2021. Interest is paid on the outstanding borrowings monthly at a rate equal to 1.625% plus adjusted LIBOR (subject to a 1% floor) for four years after the closing date and at a rate equal to 1.875% plus adjusted LIBOR (subject to a 1% floor) thereafter.
The Partnership must also pay quarterly commitment fees of 35% of the applicable margin then in effect on the undrawn portion of the available commitments. As of December 31, 2021 and 2020, there were no outstanding letters of credit.
The debt agreement contains various covenants or restrictive provisions that, amongst other things, limit or restrict the Partnership’s ability to incur certain liens on assets, make or hold certain new investments, incur or guarantee additional debt, dispose of certain assets, make certain restricted payments, change the nature of the business, or enter into any transactions with affiliates in excess of $5.0 million, all of which the Partnership is in compliance. The debt agreement also pledges the equity interests held by the Partnership in PHP as collateral.
