The fair value of such instruments is estimated based on valuations obtained from third-party pricing services that utilize industry standard valuation models, including both income-based and market-based approaches, for which all significant inputs are observable either directly or indirectly. These inputs include interest rate curves, foreign exchange rates, and credit ratings.

The Company sold $694.6 million of available-for-sale debt securities during the six months ended June 30, 2023 and immediately reinvested such proceeds into additional debt securities. The realized gains and losses from those sales were immaterial. No credit or non-credit losses related to debt securities were recorded during the three and six months ended June 30, 2024 and 2023. As of June 30, 2024 and December 31, 2023, available-for-sale debt securities of $3.1 billion and $236.0 million, respectively, were in an unrealized loss position primarily due to unfavorable changes in interest rates subsequent to initial purchase. None of the available-for-sale debt securities held as of June 30, 2024 or December 31, 2023 were in a continuous unrealized loss position for greater than 12 months. The decline in fair value below amortized cost basis was not considered other than temporary as it is more likely than not that the Company will hold the securities until maturity or a recovery of the cost basis, and no credit-related impairment losses were recorded as of June 30, 2024 or December 31, 2023. All of the Company’s U.S. treasury securities had remaining contractual maturities due within one year as of June 30, 2024. Equity Securities The Company holds equity securities in publicly-traded companies, which are recorded at fair market value each reporting period in marketable securities on the condensed consolidated balance sheets. Realized and unrealized gains and losses are recorded in other income (expense), net on the condensed consolidated statements of operations. For the three months ended June 30, 2024 and 2023, net unrealized losses from publicly-traded equity securities held at the end of each period were $6.6 million and $0.6 million, respectively. For the six months ended June 30, 2024 and 2023, net unrealized losses from publicly-traded equity securities held at the end of each period were $12.2 million and $7.0 million, respectively. The Company also holds equity securities in privately-held companies without readily determinable fair values that are recorded using the measurement alternative. As of June 30, 2024 and December 31, 2023, the total amount of privately-held equity securities included in other assets on the consolidated balance sheets was $49.9 million and $32.6 million, respectively. The Company classifies these fair value measurements as Level 3 within the fair value hierarchy. The Company did not record any material adjustments or impairments for the privately-held equity securities held during the three and six months ended June 30, 2024 and 2023. Additionally, we have accepted, and may continue to accept, securities as noncash consideration. Total equity securities received as noncash consideration was $30.3 million and $14.5 million during the six months ended June 30, 2024 and 2023, respectively. Strategic Commercial Contracts From 2021 through 2022, the Company approved and entered into certain agreements (“Investment Agreements”) to purchase shares of various entities, including special purpose acquisition companies and/or other privately-held or publicly-traded entities (each, an “Investee,” and such purchases, the “Investments”). No Investments were purchased under such Investment Agreements during the six months ended June 30, 2024 or the fiscal year ended December 31, 2023. In connection with signing the Investment Agreements, each Investee or an associated entity and the Company entered into a commercial contract for access to the Company’s products and services (collectively, the “Strategic Commercial Contracts”). The Company assessed the concurrent agreements under the noncash consideration and consideration payable to a customer guidance within Accounting Standards Codification 606, Revenue from Contracts with Customers, as well as the commercial substance of each arrangement considering the customer’s ability and intention to pay as well as the Company’s obligation to perform under each contract. The Company performs ongoing assessments of customers’ financial condition, including the consideration of customers’ ability and intention to pay, and whether all or some portion of the value of such contracts continue to meet the criteria for revenue recognition, among other factors. During the three months ended June 30, 2024 and 2023, revenue recognized from Strategic Commercial Contracts was $9.2 million and $19.4 million, respectively. During the six months ended June 30, 2024 and 2023, revenue recognized from Strategic Commercial Contracts was $33.1 million and $52.8 million, respectively. |
