On June 8, 2021, the Company amended that certain Credit Agreement dated June 1, 2020 by and among the Company, the lenders party thereto and Bank of America, N.A., as administrative agent and collateral agent (the “2020 Credit Agreement”). The 2020 Credit Agreement initially provided for a five-year senior secured term B loan facility in an aggregate principal amount of $1,050 million (the “2020 Term B Loan Facility”). In connection with the amendment (the “Amendment”), the Company made a voluntary prepayment of $50.6 million of the term loan outstanding under the 2020 Credit Agreement using cash on hand. The Amendment provided for, among other things, (i) a new tranche of term loans (the “Refinanced Term B Loans”) in an aggregate principal amount of $810.0 million, (ii) a reduction of the interest rate margin applicable to such loans to (x) in the case of base rate loans, 2.50% per annum and (y) in the case of Eurodollar loans, LIBOR plus a margin of 3.50% per annum, (iii) a prepayment premium of 1.00% in connection with any repricing transaction with respect to the Refinanced Term B Loans within six months of the closing date of the Amendment, (iv) an extension of the maturity to June 8, 2028, and (v) certain additional amendments, including amendments to provide the Company with additional flexibility under the covenant governing restricted payments. The Company commenced repaying quarterly installments under the Refinanced Term B Loans in the third quarter of 2021.

The obligations under the 2020 Credit Agreement, inclusive of any changes by the Amendment, continue to be guaranteed by the Company’s wholly-owned material domestic subsidiaries (collectively, the “Guarantors”) and continue to be secured by a lien on substantially all of the assets of the Company and the Guarantors.

The 2020 Credit Agreement, as amended, contains customary events of default, upon the occurrence of which, after any applicable cure period, the lenders will have the ability to accelerate all outstanding loans thereunder. The 2020 Credit Agreement, as amended, also contains customary representations and warranties and affirmative and negative covenants that, among other things and subject to certain exceptions, restrict the ability of the Company and its subsidiaries to create or incur certain liens, incur or guarantee additional indebtedness, merge or consolidate with other companies, transfer or sell assets and make restricted payments. The Separation did not require the Company to obtain any waivers under the 2020 Credit Agreement, and the Company completed the Separation in compliance with all of the covenants contained in the 2020 Credit Agreement. The 2020 Credit Agreement, as amended, requires the Company to maintain a total net leverage ratio of no greater than 3.00x in order access an annual basket from which to make restricted payments (such as dividend payments and share repurchases). The Company was in compliance with all requirements as of December 31, 2022. The 2020 Credit Agreement, as amended, also requires the Company to make additional cash payments on an annual basis beginning in April 2023 based on certain leverage ratios and excess cash flow generated for the immediately preceding fiscal year. The additional cash payments are applied to the remaining principal balance due at final maturity. Accordingly, as of December 31, 2022, the Company reclassified $73.5 million to current portion of long-term debt for the payment to be made under the excess cash flow provisions.

Certain lenders of the 2020 Term B Loan Facility participated in the Amendment and the changes in terms were not considered substantial. Accordingly, the Company accounted for the refinancing event for these lenders as a debt modification under ASC 470-50, “Debt — Modifications and Extinguishments.” Under its policy, the Company elected to continue to defer the unamortized debt discount and issuance costs for these continuing lenders related to the partial pay-down of the debt. Certain lenders of the 2020 Term B Loan Facility did not participate in the Amendment. Accordingly, the Company accounted for the refinancing event for these lenders as a debt extinguishment. As a result, the Company recorded an $8.0 million loss on debt extinguishment in the second quarter of 2021, related to the write-off of unamortized debt discount and issuance costs for the portions of the 2020 Term B Loan Facility considered to be extinguished.

In connection with its entry into the Amendment, the Company incurred $6.8 million in debt financing costs, of which $4.2 million were capitalized in accordance with ASC 835-30 “Debt Issuance Costs” and, together with a portion of the unamortized debt discount and issuance costs from the 2020 Term B Loan Facility, are being amortized into interest expense over the term of the Amendment. Under ASC 470-50, the remaining $2.6 million, primarily related to third-party fees, were recorded as selling, general and administrative expense in the second quarter of 2021. After the Separation, the Company remains the obligor under the Refinanced B Term Loans.

At December 31, 2022, $729.4 million in total debt was outstanding. There were also $19.9 million of unamortized debt discount and issuance costs recorded as a reduction from the carrying amount of the debt. The interest rate on the Refinanced Term B Loans as of December 31, 2022, including the amortization of debt discount and issuance costs, was 7.6% and interest is payable monthly. Interest expense was $45.3 million, $39.0 million and $37.9 million for the years ended December 31, 2022, 2021 and 2020, respectively. Amortized debt discount and issuance costs, which were included in interest expense, amounted to $4.4 million, $6.4 million and $6.3 million for the years ended December 31, 2022, 2021 and 2020, respectively.
