The 2029 Notes were issued under an Indenture, dated as of August 23, 2021, among the Company, our subsidiary guarantors party thereto, and U.S. Bank National Association, as trustee (which we refer to as the “August 2021 Indenture,” as it may be supplemented or amended from time to time). The 2029 Notes were issued at 100% of their principal amount and we received proceeds of $493.8 million, net of $6.2 million in issuance costs. The August 2021 Indenture contains certain restrictive covenants on issuing future secured debt and other transactions. The aggregate principal balance of the 2029 Notes is due August 2029, with interest only payments due semi-annually in February and August of each year, beginning on February 15, 2022.As of December 31, 2021, the aggregate obligation, inclusive of unamortized financing costs on the 2029 Notes was $494.1 million. The issuance of the 2029 Notes, along with the redemption and extinguishment of our 5.875% Senior Notes due 2025 discussed below, effectively extended the maturity of our senior notes by more than four years, increased the aggregate principal amount by $100.0 million and reduced our weighted average rate on our senior notes by approximately 105 basis points.6.750% Senior Notes Due 2027In May 2019, we completed a private offering of $500.0 million aggregate principal amount of the Company’s Initial 6.750% Senior Notes due 2027 (which we refer to as the “Initial Notes due 2027”) in reliance on Rule 144A and Regulation S under the Securities Act of 1933. The Initial Notes due 2027 were issued under the Indenture, dated as of May 23, 2019, among the Company, our subsidiary guarantors party thereto, and U.S. Bank National Association, as trustee (which we refer to as the “May 2019 Indenture,” as it may be supplemented or amended from time to time). The Initial Notes due 2027 were issued at 100% of their principal amount and we received net proceeds of $493.9 million. In connection with this issuance, we deferred $6.1 million of issuance costs, which is presented in the notes payable line item of the consolidated balance sheet. In February 2020, we completed an offer to exchange approximately $500.0 million in aggregate principal amount of our Initial Notes due 2027, which are registered under the Securities Act (which we refer to as the “Exchange Notes due 2027”), for an equivalent amount of the Initial Notes due 2027 that were tendered and accepted for exchange.  The terms of the Exchange Notes due 2027 are identical in all material respects to the Initial Notes due 2027, except that the Exchange Notes due 2027 are registered under the Securities Act and the transfer restrictions, registration rights, and additional interest provisions that are applicable to the Initial Notes due 2027 do not apply to the Exchange Notes due 2027.The Initial Notes due 2027 and Exchange Notes due 2027 (which we refer to collectively, as the “Existing Notes due 2027”) will be treated as a single series of notes under the May 2019 Indenture, and will vote as a single class of notes for all matters submitted to a vote of holders under the May 2019 Indenture. The Existing Notes due 2027 are unsecured senior obligations which are guaranteed on an unsecured senior basis by certain of our current and future subsidiaries. The May 2019 Indenture governing the Existing Notes due 2027 contains certain restrictive covenants on issuing future secured debt and other transactions.  The aggregate principal balance of the Existing Notes due 2027 is due July 2027, with interest only payments due semi-annually in June and December of each year, which began on December 1, 2019. As of December 31, 2021, the aggregate obligation, inclusive of unamortized financing costs on the Existing Notes due 2027, was $495.6 million.Redemption and Extinguishment of 5.875% Senior Notes Due 2025During the year ended December 31, 2021, we redeemed $400.0 million in outstanding principal of our 5.875% Senior Notes due 2025 at a redemption price equal to 102.938% of the principal amount, plus accrued and unpaid interest, totaling $414.8 million. The redemption transaction resulted in a $14.5 million loss on debt extinguishment in our consolidated statement of operations. Revolving Line of CreditOn May 21, 2021, we entered into a Second Amended and Restated Credit Agreement (which we refer to as the “Second A&R Credit Agreement”) with Texas Capital Bank, National Association, as Administrative Agent and L/C Issuer, and the lenders party thereto. The Second A&R Credit Agreement, which amended and restated our prior Amended and Restated Credit Agreement, provides us with a senior unsecured revolving line of credit (which we refer to as the “Credit Facility”) of up to $800.0 million, and unless terminated earlier, will mature on April 30, 2026. The Credit Facility includes a $250.0 million sublimit for standby letters of credit. Under the terms of the Second A&R Credit Agreement, the Company is entitled to request an increase in the size of the Credit Facility by an amount not exceeding $200 million. Our obligations under the Second A&R Credit Agreement are guaranteed by certain of our subsidiaries. The Second A&R Credit Agreement contains customary affirmative and negative covenants (including limitations on our ability to grant liens, incur additional debt, pay dividends, redeem our common stock, make certain investments and engage in certain merger, consolidation or asset sale transactions), as well as customary events of default. Borrowings under the Second A&R Credit Agreement bear interest at a floating rate equal to the adjusted Eurodollar Rate plus an applicable margin between 2.05% and 2.65% per annum, and if made available in the Administrative Agent’s discretion, a base rate plus an applicable margin between 1.05% and 1.65% per annum. As of December 31, 2021, no amounts were outstanding under the credit facility and were in compliance with all covenants. Mortgage Repurchase Facilities – Financial Services On May 4, 2018, September 14, 2018 and August 1, 2019, Inspire entered into mortgage warehouse facilities, with Comerica Bank, J.P. Morgan and Wells Fargo, respectively. The mortgage warehouse lines of credit (which we refer to as the “Repurchase Facilities”), which were increased during 2020, provide Inspire with uncommitted repurchase facilities of up to $400 million as of December 31, 2021, secured by the mortgage loans financed thereunder. The repurchase facilities have varying short term maturity dates through August 23, 2022 and bear a weighted average interest rate of 2.13%.Amounts outstanding under the Repurchase Facilities are not guaranteed by us or any of our subsidiaries and the agreements contain various affirmative and negative covenants applicable to Inspire that are customary for arrangements of this type. As of December 31, 2021 and 2020, we had $331.9 million and $259.1 million outstanding under these Repurchase Facilities, respectively, and were in compliance with all covenants thereunder. During the years ended December 31, 2021 and 2020, we incurred interest expense on our Repurchase Facilities of $2.1 million and $3.0 million, respectively, which are included in financial services costs on our consolidated statements of operations.Other Financing ObligationsAs of December 31, 2021, we had no outstanding land development notes and $9.2 million of outstanding insurance premium notes, compared to $2.0 million of outstanding land development notes and $1.3 million outstanding insurance premium notes as of December 31, 2020.
