There were no changes in valuation techniques or transfers between fair value measurement levels during the nine months ended September 30, 2022. Marketable securities classified as Level 1 within the valuation hierarchy generally consists of U.S. treasury securities, as the fair value is readily determinable based on active daily markets for identical securities. Marketable securities classified as Level 2 within the valuation hierarchy generally consists of U.S. government agency securities, as the fair value is readily determinable based on active daily markets for similar securities and other observable inputs. The Company estimates the fair values of marketable securities by taking into consideration valuations obtained from third-party pricing sources. The carrying amounts reflected in the consolidated balance sheets for prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values due to their short-term nature. As of September 30, 2022 and December 31, 2021, the carrying value of the Company’s outstanding borrowing under the New Credit Facility (as defined in Note 7) approximated fair value (a Level 2 fair value measurement), reflecting interest rates currently available to the Company. The New Credit Facility is discussed in more detail in Note 7, Debt.
