Fair Value Hierarchy
The Company measures its financial instruments at fair value. The Company’s cash, cash equivalents, and restricted cash are classified within Level 1 of the fair value hierarchy as they are valued primarily using quoted market prices utilizing market observable inputs. The Company’s credit facility is classified within Level 2 as the valuation inputs are based on quoted prices or market observable data of similar instruments. The Company’s convertible senior notes are classified within Level 2 as the valuation inputs are based on quoted prices in an inactive market on the last day in the reporting period. As of March 31, 2023 and December 31, 2022, the fair value of the convertible senior notes was $528.4 million and $501.4 million, respectively, compared to their carrying values of $567.3 million and $566.6 million, respectively, which are net of unamortized debt issuance costs.
