There were no financial liabilities measured at fair value. The Company classifies money market funds within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The Company classifies its investments in U.S. Treasury securities (Treasury bills, Treasury notes, and Treasury bonds) as Level 2 instruments and obtains fair value from an independent pricing service, which may use quoted market prices for identical or comparable instruments or model-driven valuations using observable market data or inputs corroborated by observable market data.

The carrying amount of the Company’s accounts receivable, other receivables, prepaid expenses and other current assets, accounts payable, and accrued expenses approximate fair value due to their short maturities.

The following is a summary of the Company’s cash equivalents and investments and the gross unrealized holding gains and losses (in thousands):

As of March 31, 2023 and December 31, 2022, unrealized losses on available-for-sale investments are not attributable to credit risk and are considered to be temporary. Approximately $0.1 million of the Company’s investments have been in a continuous unrealized loss position for 12 months or longer. The Company believes it is more likely than not that investments in an unrealized loss position will be held until maturity or the recovery of the cost basis of the investment. To date, the Company has not recorded any impairment charges on marketable securities related to other-than-temporary declines in market value. As of March 31, 2023, $58.4 million of available-for-sale investments had remaining maturities between one and two years. The remainder of the available-for-sale investments have a remaining maturity of one year or less. As of March 31, 2023 and December 31, 2022, the Company recorded $0.7 million and $0.6 million of accrued interest, respectively, related to its available-for-sale investments as a component of other receivables on the condensed consolidated balance sheets.
