Fair Value Disclosures [Abstract] |
Fair Value Accounting | FAIR VALUE ACCOUNTING Assets and liabilities measured at fair value on a recurring basis The following tables set forth the fair value of the Company’s assets and liabilities measured at fair value on a recurring basis (at least annually) by level within the fair value hierarchy as of September 30, 2022 and December 31, 2021. As required by accounting guidance, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. As of September 30, 2022 and December 31, 2021, the fair values of cash, restricted cash, short-term deposits, receivables, accounts payable and accrued liabilities approximate their carrying values because of the short-term nature of these instruments.
