Fair Value Measurements

3 Months Ended

Mar. 31, 2023

(6) Fair Value Measurements

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of the short maturity of these items.

Certain assets, including long-lived assets, goodwill and intangible assets are also subject to measurement at fair value on a non-recurring basis if they are deemed to be impaired as a result of an impairment review. For the three months ended March 31, 2023 and year ended December 31, 2022, no impairments were identified of those assets requiring measurement at fair value on a non-recurring basis.

The following table summarizes the Company's financial assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy. Financial assets and financial liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement (in thousands):

The Company classifies and discloses fair value measurements in one of the following three categories of fair value hierarchy:


Level 1 -	Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets and liabilities.


Level 2 -	Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.


Level 3 -	Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company’s assets that are measured by management at fair value on a recurring basis are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company did not have any transfers into or out of Level 3 during the three months ended March 31, 2023.

The Company considers all highly liquid investments purchased with a remaining maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value and such instruments are classified as Level 1 and are included in cash and cash equivalents on the condensed consolidated balance sheets.

The Company estimates the fair value of the convertible senior notes based on market-observable inputs (Level 2). As of March 31, 2023 and December 31, 2022, the fair value of the 0% convertible senior notes due March 15, 2026 (the "2026 Notes") was determined to be $313.4 million and $320.5 million, respectively, and the principal amount of the notes was $375.0 million for each period. As of March 31, 2023 and December 31, 2022, the fair value of the 0.125% convertible senior notes due December 15, 2024 (the “2024 Notes”) was determined to be $118.3 million and $118.2 million, respectively, and the principal amount of the notes was $133.6 million for each period.
