When developing fair value estimates, we maximize the use of observable inputs and minimize the use of unobservable inputs. When available, we use quoted market prices to measure fair value. The valuation technique used to measure fair value for our Level 1 and Level 2 assets is a market approach, using prices and other relevant information generated by market transactions involving identical or comparable assets. If market prices are not available, the fair value measurement is based on models that use primarily market-based parameters including yield curves, volatilities, credit ratings and currency rates. Assets and Liabilities Not Carried at Fair Value Fair Value of the Convertible Senior Notes The following table details the fair value and carrying value of our Convertible Senior Notes due 2026 and 2030 (together referred to as “the Notes”):
| August 31, 2024 |  | November 30, 2023
(in thousands) | Carrying Value |  | Fair Value |  | Carrying Value |  | Fair Value
Convertible senior notes due 2026(1) | $ | 356,416 |  |  | $ | 390,268 |  |  | $ | 354,772 |  |  | $ | 377,125 |
Convertible senior notes due 2030(2) | 438,866 |  |  | 483,188 |  |  | — |  |  | — |
Total | $ | 795,282 |  |  | $ | 873,456 |  |  | $ | 354,772 |  |  | $ | 377,125 |
(1) The carrying value of the convertible senior notes due 2026 (the "2026 Notes"), are reflected net of $3.6 million and $5.2 million of unamortized debt issuance costs as of August 31, 2024 and November 30, 2023, respectively. (2) The carrying value of the convertible senior notes due 2030 (the "2030 Notes"), are reflected net of $11.1 million of unamortized debt issuance costs as of August 31, 2024. The fair value of the Notes is based on quoted prices in an over-the-counter market on the last trading day of the reporting period and classified within Level 2 of the fair value hierarchy. Fair Value of Other Financial Assets and Liabilities The carrying amounts of other financial assets and liabilities including cash and cash equivalents, accounts receivable, unbilled accounts receivable, accounts payable, and accrued liabilities approximate their respective fair values due to their immediate or short-term maturities.
