2023 Convertible Notes. In September 2023, we completed an offering of $425.0 million of 3.875% senior convertible notes due September 15, 2028 (the "2023 Convertible Notes") to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The 2023 Convertible Notes are unsecured obligations and will pay 3.875% annual cash interest, payable semiannually in arrears on March 15 and September 15 of each year, beginning on March 15, 2024. The 2023 Convertible Notes will be convertible at the option of the noteholders before June 15, 2028 upon the occurrence of certain events. On or after June 15, 2028 and until the close of business on the second scheduled trading day immediately preceding the maturity date, noteholders may convert all or any portion of their notes at any time regardless of these conditions. We are required to satisfy our conversion obligation as follows: (i) paying cash up to the aggregate principal amount of notes to be converted; and (ii) to the extent the value of our conversion obligation exceeds the par value, we will satisfy the remaining conversion obligation in our common stock, cash, or a combination thereof, at our election. As of September 30, 2023, none of the conditions to early convert have been met. The 2023 Convertible Notes will be convertible at an initial conversion rate of 14.0753 shares of our common stock per $1,000 principal amount of the 2023 Convertible Notes, which is equivalent to an initial conversion price of approximately $71.05 per share of our common stock. The conversion rate and conversion price will be subject to adjustment upon the occurrence of certain events. Under the terms of the 2023 Convertible Notes, we will adjust the conversion rate for any quarterly dividends exceeding $0.28 per share. Holders may require us, subject to certain conditions, to repurchase all or a portion of their 2023 Convertible Notes for cash upon the occurrence of a fundamental change (as defined in the Indenture related to the 2023 Convertible Notes (“2023 Notes Indenture”)). The repurchase price will be equal to the principal amount thereof plus accrued and unpaid interest to, but excluding, the repurchase date. We may not redeem the 2023 Convertible Notes prior to September 21, 2026. On or after September 21, 2026, we may redeem for cash all or part of the 2023 Convertible Notes, subject to a partial redemption limitation that requires at least $100.0 million of the principal amount of the 2023 Convertible Notes to remain outstanding if the last reported sales price 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. The redemption price will equal the principal amount of the 2023 Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund has been established for the 2023 Convertible Notes. The 2023 Notes Indenture includes customary terms, including certain events of default after which the 2023 Convertible Notes may be due and payable immediately. The 2023 Notes Indenture contains customary affirmative covenants, including a reporting covenant. In September 2023, in connection with the pricing of the 2023 Convertible Notes, we entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain of the initial purchasers of the 2023 Convertible Notes and other financial institutions (collectively, the “Option Counterparties”). We used $34.3 million of the net proceeds from the offering of the 2023 Convertible Notes to pay the premiums of the Capped Call Transactions. The Capped Call Transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the 2023 Convertible Notes, 5.98 million shares of our common stock, the same number of shares of common stock underlying the 2023 Convertible Notes. The Capped Call Transactions will expire upon the maturity of the 2023 Convertible Notes.45 The Capped Call Transactions are expected generally to reduce the potential dilution to the common stock upon conversion of the 2023 Convertible Notes and/or offset any cash payments we are required to make in excess of the principal amount of the 2023 Convertible Notes, in the event that the market price per share of common stock (as measured under the terms of the Capped Call Transactions) is greater than the strike price of the Capped Call Transactions. The strike price of the Capped Call Transactions initially corresponds to the initial conversion price of the 2023 Convertible Notes, or approximately $71.05 per share of our common stock. The Capped Call Transactions have an initial cap price of approximately $96.52 per share of our common stock, which represents a premium of 80% over the last reported sale price of our common stock on the date the 2023 Convertible Notes were issued, subject to certain adjustments under the terms of the Capped Call Transactions. The Capped Call Transactions are separate transactions, entered into by us with the Option Counterparties. They are not part of the terms of the 2023 Convertible Notes and do not change the holders’ rights under the 2023 Convertible Notes. Holders of the 2023 Convertible Notes do not have any rights with respect to the Capped Call Transactions. The Capped Call Transactions do not meet the criteria for separate accounting as a derivative as they meet the criteria for equity classification. The premiums paid for the Capped Call Transactions of $34.3 million have been included as a reduction to additional paid-in capital, net of $7.9 million of deferred income taxes. The proceeds from the sale of the 2023 Convertible Notes, net of financing costs, were $411.0 million. We used the net proceeds to: (i) repay the principal amount of $275.0 million of outstanding borrowings under our $450.0 million, five-year revolving loan facility (the "2021 Revolver"); (ii) repurchase 1.7 million shares of our common stock for $90.1 million in privately negotiated transactions, concurrently with the pricing of the offering of the 2023 Convertible Notes; and (iii) pay the $34.3 million premium for the Capped Call Transactions. The remaining net proceeds were used for general corporate purposes. In conjunction with the closing of the 2023 Convertible Notes, we incurred financing costs of $14.0 million which are being amortized to interest expense using the effective interest method through maturity. 2021 Credit Agreement. During the nine months ended September 30, 2023, we made $5.6 million of principal repayments on our $150.0 million aggregate principal five-year term loan (the “2021 Term Loan”). In conjunction with the issuance of the 2023 Convertible Notes, we repaid $275.0 million on our 2021 Revolver. As of September 30, 2023, we had $15.0 million outstanding on our 2021 Revolver, leaving $435.0 million available to us. As of September 30, 2023, the interest rate on our 2021 Term Loan and our 2021 Revolver was 7.115% (adjusted SOFR, credit spread adjustment of 0.10%, plus 1.625% per annum), effective through December 2023, and our commitment fee on the unused 2021 Revolver was 0.20%. The interest rates under the 2021 Credit Agreement are based upon our choice of an adjusted SOFR rate plus an applicable margin of 1.375% - 2.125%, or an alternate base rate (“ABR”) plus an applicable margin of 0.375% - 1.125%, with the applicable margin, being determined in accordance with our then-net secured total leverage ratio. We pay a commitment fee of 0.150% - 0.325% of the average daily unused amount of the 2021 Revolver, with the commitment fee rate being determined in accordance with our then-net secured total leverage ratio. In April 2023, we entered into the First Amendment to the 2021 Credit Agreement (the “First Amendment”). The First Amendment replaced the interest rate benchmark, from LIBOR to the Secured Overnight Financing Rate ("SOFR"), and all references to “Eurodollar Borrowing(s)” or “Eurodollar Loans” were replaced with “Term SOFR Borrowing(s)” or “Term SOFR Loans”. Any loan amounts outstanding at the effective date of the First Amendment continued to bear interest at the applicable LIBOR rate until the end of the interest election period applicable to such loan. All Term SOFR Loans are subject to a 0.10% credit spread adjustment. In September 2023, we entered into the Second Amendment to the 2021 Credit Agreement (the “Second Amendment”). The Second Amendment permits the issuance and sale of the 2023 Convertible Notes and the related Capped Call Transactions (described above). In conjunction with the Second Amendment, we incurred financing costs of $0.5 million.
