Highly liquid investments with an original maturity of three months or less at time of purchase are included in cash and cash equivalents on the consolidated balance sheet.

Level 1 assets are priced using quoted prices in active markets for identical assets which include money market funds and U.S. Treasury securities as these specific assets are liquid.

Level 2 available-for-sale securities are priced using quoted market prices for similar instruments or nonbinding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets and liabilities. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs.

There were no transfers between levels during the year ended December 31, 2022.

The Company has Notes, as described in Note 10, Convertible Notes. At December 31, 2022, the Notes had an outstanding principle of $56.6 million with a fair value of $51.9 million. At December 31, 2021, the Notes had an outstanding principle of $120.5 million with a fair value of $89.4 million. The fair value of the Notes is classified as Level 2 within the fair value hierarchy.

The Secured Note is an instrument measured at fair value on a non-recurring basis using Level 3 inputs. The estimated fair value of the Secured Note on August 15, 2022 was $16.0 million. See Note 11, Long-Term Debt Related-Party for further detail on the Secured Note.

The warrant is an instrument measured at fair value on a non-recurring basis using Level 3 inputs. The estimated fair value of the warrant on August 15, 2022 was $3.8 million. See Note 11, Long-Term Debt Related-Party for further detail on the Company’s warrant with a related-party.

For certain other financial assets and liabilities, including accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances.
