The Notes will mature on July 24, 2031, unless previously redeemed or repurchased in accordance with their terms. The interest rate of the Notes is 6.300% per year and will be paid semiannually in arrears on January 24 and July 24 of each year, commencing January 24, 2027. The Notes are the Company’s unsecured obligations that rank senior in right of payment to all of the Company’s existing and future indebtedness that is expressly subordinated, or junior, in right of payment to the Notes. The Notes will not be guaranteed by any of the Company’s current or future subsidiaries. The Notes will rank pari passu, or equally, in right of payment with all of the Company’s existing and future liabilities that are not so subordinated, or junior. The Notes will effectively rank subordinated, or junior, to any of the Company’s secured indebtedness (including unsecured indebtedness that the Company later secures) to the extent of the value of the assets securing such indebtedness. The Notes will rank structurally subordinated, or junior, to all existing and future indebtedness (including trade payables) incurred by the Company’s subsidiaries, financing vehicles or similar facilities.
