The carrying value of the Company’s short-term financial instruments, including accounts receivable and accounts payable approximate fair value due to the short-term nature of these instruments. As of July 31, 2024, the carrying value of the Company's debt and deferred consideration liabilities approximate fair value because the interest rates approximate market rates and the related maturities are relatively short-term.
The Company did not have any transfers of assets and liabilities between levels of the fair value measurement hierarchy during the six months ended July 31, 2024 and 2023.
