Debt
For the periods ended December 31, 2025 and 2024, the carrying value of our outstanding debt was $1,491 million and $1,489 million, respectively, net of unamortized debt discount and issuance costs of $9 million and $11 million, respectively.
We consider the fair value of the 2030 Notes at December 31, 2025 and 2024 to be a Level 2 measurement. The estimated fair value of the 2030 Notes based on the closing trading price per $100, was $1,324 million and $1,247 million at December 31, 2025 and 2024, respectively.
2030 Notes
In August 2020, we issued 1.40% fixed rate ten-year notes with an aggregate principal amount of $1.5 billion due on September 1, 2030 (the “2030 Notes”). The 2030 Notes were issued at 99.63% of principal and we incurred $13 million for debt issuance costs. The effective interest rate for the 2030 Notes was 1.53% and included interest payable, amortization of debt issuance cost and amortization of debt discount. Interest is payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2021, and the entire outstanding principal amount is due at maturity on September 1, 2030. The 2030 Notes are unsecured obligations and the indentures governing the 2030 Notes contain customary events of default and covenants that, among others and subject to exceptions, restrict our ability to incur or guarantee debt secured by liens on specified assets or enter into sale and lease-back transactions with respect to specified properties.
About Debt Disclosures
Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.
Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
