1 Interest rate fluctuates based on LIBOR plus an applicable margin set on the date of each advance. The margin above LIBOR is set every three months. All amounts outstanding at December 31, 2021 were at LIBOR plus an applicable margin of 4.00%, with LIBOR having a floor of 1.00%. The applicable margin for revolving loans that are LIBOR loans currently ranges from 2.75% to 4.00% and the applicable margin for revolving loans that are base prime rate loans ranges from 1.75% to 3.00%. The credit facility contains various covenants which limit the Partnership’s ability to make distributions; make certain investments and acquisitions; enter into certain agreements; incur indebtedness; sell assets; and make certain amendments to the Partnership's omnibus agreement with Martin Resource Management Corporation (the "Omnibus Agreement"). The credit facility was amended July 16, 2021 to, among other things, reduce the commitments thereunder from $300,000 to $275,000. 2 The Partnership was in compliance with all debt covenants as of December 31, 2021. 3 The indentures for each of the outstanding senior notes restrict the Partnership’s ability to sell assets; pay distributions or repurchase units or redeem or repurchase subordinated debt; make investments; incur or guarantee additional indebtedness or issue preferred units; and consolidate, merge or transfer all or substantially all of its assets. 4 On February 15, 2021, our 2021 Notes matured and we retired the outstanding balance of $28,790 using proceeds from our credit facility. 5 In March 2020, the Partnership repurchased on the open market an aggregate $9,344 of the 2021 Notes, resulting in a gain on retirement of $3,484.
