Debt Disclosure [Abstract] |
Debt | Debt Credit Facilities On January 18, 2024 we entered into a credit and guaranty agreement with Ares Management Credit funds for $350.0 million of senior secured, interest-only, credit facilities, consisting of a $190.0 million secured term loan facility (the “Initial Term Loan Facility”), a $100.0 million secured delayed draw term loan facility (the “Delayed Draw Term Loan Facility” and, together with the Initial Term Loan Facility, the “Term Loan Facilities”) and a $60.0 million “senior-priority” secured revolving credit facility which has a priority claim ahead of the other secured facilities (the “Revolving Credit Facility” and, together with the Term Loan Facilities, the “Credit Facilities”). The final scheduled maturity date of the Credit Facilities is January 18, 2030. There are no scheduled repayments of principal required to be made prior to the final maturity date. We have the right to prepay loans under the Ares Credit Agreement in whole or in part at any time, provided that any prepayment of loans under the Term Loan Facilities (or loans under the Revolving Credit Facility to the extent of reducing the balance of outstanding loans below $30.0 million) will be subject to a prepayment premium of 5.00% if the prepayment occurs prior to January 18, 2025 and 1.00% if the prepayment occurs thereafter and prior to January 18, 2026. Amounts repaid in respect of loans under the Initial Term Loan Facilities may not be reborrowed. The Credit Facilities are secured by a security interest in substantially all existing and after-acquired real and personal property (subject to certain exceptions and exclusions) of us and the Guarantors. Upon closing, we borrowed $190.0 million under the Initial Term Loan Facility and $30.0 million under the Revolving Credit Facility. The remaining $30.0 million of undrawn availability under the Revolving Credit Facility may be drawn for working capital, capital expenditures, and other general corporate purposes. The Delayed Draw Term Loan Facility remained undrawn as of June 30, 2024. We paid $6.5 million of debt issuance costs related to the Initial Term Loan Facility which are included in Long-term debt on the Condensed Consolidated Balance Sheets as of June 30, 2024 and amortized, thereafter, over the life of the Initial Term Loan Facility. We paid $3.7 million of debt issuance costs related to the Delayed Draw Term Loan Facility and Revolving Credit Facility which are included in Other long-term assets on the Condensed Consolidated Balance Sheets as of June 30, 2024. We recognized $6.9 million and $12.7 million of interest expense on the Credit Facilities for the three and six months ended June 30, 2024, respectively, of which $298,000 and $639,000 represent non-cash amortization of debt issuance costs for the three and six months ended June 30, 2024, respectively. There was approximately $6.0 million of unamortized debt issuance costs related to the Initial Term Loan Facility as of June 30, 2024. The proceeds of the initial borrowings were used along with cash on hand to pay off our previously existing credit agreement, dated as of December 1, 2017, and pay related fees and expenses. As a result of this transaction, we recorded a loss on extinguishment of our previously existing debt of $3.7 million during the six months ended June 30, 2024 on our Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income. The proceeds of borrowings under the Delayed Draw Term Loan Facility may be used solely to repurchase or repay our outstanding 4.25% Convertible Senior Notes due July 1, 2025 and to pay related fees and expenses. Subject to the satisfaction of a specified maximum total net leverage ratio and other customary conditions, we may borrow under the Delayed Draw Term Loan Facility at any time and from time to time on or prior to the maturity date of the convertible bonds on July 1, 2025. Loans borrowed under the Delayed Draw Term Loan Facility generally have the same terms as the loans under the Initial Term Loan Facility. The Credit Facilities contain certain customary affirmative and negative covenants, including covenants that limit our ability and the ability of our subsidiaries to, among other things, grant liens, incur debt, dispose of assets, make loans and investments, make acquisitions, make certain restricted payments (including cash dividends), merge or consolidate, change business or accounting or reporting practices, in each case subject to customary exceptions for a credit facility of this size and type. The covenants include a financial maintenance covenant that requires the company’s total net leverage ratio, as defined in the agreement, to be not greater than 6.25x for the test periods from the second quarter of fiscal year 2024 through the fourth quarter of fiscal year 2024 and not greater than 5.75x from the first quarter of fiscal year 2025 and thereafter. As of June 30, 2024 we are in compliance with our debt covenants. The Revolving Credit Facility bears interest, at our option, at a floating annual rate equal to either the base rate plus a margin of 3.00%, or the Adjusted Term Secured Overnight Financing Rate (“Adjusted Term SOFR”) plus a margin of 4.00%. In addition, we will be required to pay fees of 0.50% per annum on the daily unused amount of the Revolving Credit Facility and 1.00% per annum on the daily unused amount of the Delayed Draw Term Loan Facility. The Term Loan Facilities initially bear interest, at our option, at a floating annual rate equal to either the base rate plus a margin of 5.50%, or the Adjusted Term SOFR plus a margin of 6.50%. If, after the second quarter of fiscal year 2025, the company reports total net leverage ratio, as defined in the Credit Facilities, of less than or equal to 3.75x the interest margins applicable to the Term Loan Facilities will be reduced by 25 basis points, to 5.25% and 6.25%, for base rate and Adjusted Term SOFR loans, respectively. As of June 30, 2024 the aggregate interest rate was 11.83% and 9.33% per annum for the Term Loan Facilities and Revolving Credit Facility, respectively. Convertible Senior Notes On June 18, 2020 we issued $100.0 million aggregate principal amount of 4.25% Convertible Senior Notes with a maturity date of July 1, 2025 (the “Convertible Senior Notes”). The net proceeds from this offering, after deducting initial purchasers’ discounts and costs directly related to this offering, were approximately $96.5 million. On January 1, 2021 we adopted ASU 2020-06 and adjusted the carrying balance of the Convertible Senior Notes to notional. The Convertible Senior Notes balance was $100.0 million recorded in Long-term debt on the Condensed Consolidated Balance Sheets as of June 30, 2024 and the Consolidated Balance Sheets as of December 31, 2023. The Convertible Senior Notes may be settled in cash, stock, or a combination thereof, solely at our discretion. The initial conversion rate of the Convertible Senior Notes is 42.6203 shares per $1,000 principal amount, which is equivalent to a conversion price of approximately $23.46 per share, subject to adjustments. We use the if-converted method for assumed conversion of the Convertible Senior Notes for the diluted earnings per share calculation. The fair value and the effective interest rate of the Convertible Senior Notes as of June 30, 2024 was approximately $125.5 million and 5.05%, respectively. The fair value was based on market prices observable for similar instruments and is considered Level 2 in the fair value hierarchy. The interest expense recognized on the Convertible Senior Notes includes $1.2 million and $2.5 million for both the three and six months ended June 30, 2024 and 2023, respectively, related to the aggregate of the contractual coupon interest and the amortization of the debt issuance costs. Interest on the Convertible Senior Notes began accruing upon issuance and is payable semi-annually. There were approximately $770,000 and $1.1 million of unamortized debt issuance costs related to the Convertible Senior Notes as of June 30, 2024 and December 31, 2023, respectively. Holders of the Convertible Senior Notes may convert their notes at their option at any time prior to January 1, 2025, but only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; (iii) we give a notice of redemption with respect to any or all of the notes, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate events. On or after January 1, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances. We became eligible to redeem the Convertible Senior Notes beginning on July 5, 2023, following the expiration of their non-redemption period. We are able to redeem the Convertible Senior Notes in whole or in part, at our option, if the last reported sale price per share of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. We may redeem for cash all or part of the Convertible Senior Notes at a redemption price equal to 100% of the principal amount of the redeemable Convertible Senior Notes, plus accrued and unpaid interest to, but excluding, the redemption date. No principal payments are due on the Convertible Senior Notes prior to maturity. Other than restrictions relating to certain fundamental changes and consolidations, mergers or asset sales and customary anti-dilution adjustments, the Convertible Senior Notes do not contain any financial covenants and do not restrict us from conducting significant restructuring transactions or issuing or repurchasing any of our other securities. As of June 30, 2024 and December 31, 2023 we are not aware of any current events or market conditions that would allow holders to convert the Convertible Senior Notes.
