Level 3 Investments

Convertible Note

In the fourth quarter of 2021, we invested $2.0 million in a non-marketable convertible note. This debt security was classified as available-for-sale and included in Other assets on the Consolidated Balance Sheet. During the three months ended March 31, 2024, we recorded a $2.0 million impairment loss related to this Level 3 investment. The impairment loss is included in Other income (expense), net on the Consolidated Statements of Operations.
