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 condensed consolidated balance sheet.

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

In 2018, the Company issued the Notes, for total proceeds of $171.5 million, as described in Note 10, Convertible Notes. At June 30, 2021 and December 31, 2020, the fair value of the Notes were $112.7 million and $98.7 million, respectively. The fair value of the Notes is highly correlated to the Company’s stock price and as a result, significant changes to the Company’s stock price will have a significant impact on the calculated fair value. The fair value of the Notes are classified as Level 2 within the fair value hierarchy. See Note 10, Convertible Notes for further detail on the Company’s convertible notes.

The Company's PPP Note along with its other long-term notes, cumulatively $5.3 million, approximate their fair value. The estimated fair value of the Company’s long-term debt represents a Level 3 measurement. See Note 9, Long-Term Debt for further detail on the Company's long-term debt.
