The fair value estimates for cash, cash equivalents and restricted cash and cash equivalents were classified as Level 1 and other current assets, customer deposits, and other current liabilities were classified as Level 2 of the fair value hierarchy. Other assets and other liabilities. At January 31, 2020 and July 31, 2019, the carrying amount of these assets and liabilities approximated fair value.
