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 fair value of our Convertible Senior Notes, with a carrying value of $355.3 million and $354.8 million, was $378.0 million and $377.1 million as of February 29, 2024 and November 30, 2023, respectively. The fair value was determined based on the quoted price in an over-the-counter market on the last trading day of the reporting period and classified within Level 2 in the fair value hierarchy.

Fair Value of Other Financial Assets and Liabilities
The carrying amounts of other financial assets and liabilities including cash, accounts receivable, unbilled accounts receivable, accounts payable, and accrued liabilities approximate their respective fair values because of the relatively short period of time between their origination and their expected realization or settlement.
