DEBT

At December 31, 2019 and March 31, 2020, our Credit Facility was comprised of: (i) a $190.0 million revolving credit facility, which includes a $15.0 million subfacility for letters of credit and a $10.0 million swingline, and (ii) an accordion or incremental option allowing for future increases in the facility size by an additional amount of up to $75.0 million in the form of increased revolving commitments or incremental term loans. The final maturity of the Credit Facility will occur on May 31, 2023.

The Credit Facility contains customary affirmative covenants, including, but not limited to, covenants with respect to the use of proceeds, payment of taxes and other obligations, continuation of the Company’s business and the maintenance of existing rights and privileges, the maintenance of property and insurance, amongst others.

In addition, the Credit Facility also contains customary negative covenants, including, but not limited to, covenants that restrict (subject to certain exceptions) the ability of the Company and its subsidiaries and party thereto as guarantors (the “Credit Facility Guarantors”) to incur additional indebtedness, grant liens on assets, make investments, engage in mergers and acquisitions, and pay dividends and other restricted payments, and certain financial covenants. As of March 31, 2020, we were subject to the following financial covenant under our Credit Facility: (A) a Total Leverage Ratio not to exceed, (i) 5.75 to 1.00 for the quarters ended March 31, 2020, June 30, 2020 and September 30, 2020 and (ii) 5.50 to 1.00 for the quarter ended December 31, 2020 and each quarter ended thereafter, (B) a Senior Secured Leverage Ratio (as defined in the Credit Facility) not to exceed 2.00 to 1.00 as of the end of any period of four consecutive fiscal quarters, and (C) a Fixed Charge Coverage Ratio (as defined in the Credit Facility) of not less than 1.20 to 1.00 as of the end of any period of four consecutive fiscal quarters. These financial maintenance covenants are calculated for the Company and its subsidiaries on a consolidated basis. As more fully described below, we were not in compliance with the Total Leverage Ratio covenant for the quarter ended March 31, 2020.

As of March 31, 2020, the Company was not in compliance with the then current Total Leverage Ratio covenant as noted above. On May 18, 2020, we received a waiver under our Credit Facility for the failure to comply with such Total Leverage Ratio and the Credit Facility was also amended whereby the interest rate margin applicable to borrowings was increased at each pricing level. See Note 19 for additional information related to our debt covenant limited waiver and fourth amendment to our Credit Facility.

We are in compliance with the fixed charge coverage ratio and senior secured leverage ratio covenants contained in our Credit Facility as of March 31, 2020.

We had one letter of credit issued on November 30, 2019 and outstanding under the Credit Facility for approximately $2.0 million, which bears interest at 2.125% and will expire on November 25, 2020. The letter of credit automatically renews annually and secures our obligations under our various self-insured policies. Outstanding borrowings under our Credit Facility bear interest at either a prime rate or a LIBOR rate, plus an applicable margin based upon our leverage ratio. As of March 31, 2020, the prime rate margin was equivalent to 1.50% and the LIBOR rate margin was 2.50%. The weighted average interest rate on our Credit Facility for the three months ended March 31, 2019 and 2020 was 4.1% and 4.3%, respectively.

Interest expense related to our Credit Facility was $0.4 million and $1.2 million for the three months ended March 31, 2019 and 2020, respectively. Amortization of debt issuance costs related to our Credit Facility was $0.1 million for both the three months ended March 31, 2019 and 2020.

Acquisition debt consists of deferred purchase price and promissory notes payable to sellers. A majority of the deferred purchase price and notes bear no interest and are discounted at imputed interest rates ranging from 7.3% to 10.0%. Original maturities range from five to twenty years. Imputed interest expense related to our acquisition debt was $0.2 million and $0.1 million for the three months ended March 31, 2019 and 2020, respectively.
