Revenue from Contract with Customer [Text Block]	(11)DEFERRED REVENUE AND REMAINING PERFORMANCE OBLIGATIONS Revenue recognized for the six months ended June 30, 2025 from amounts included in deferred revenue as of December 31, 2024 was $50.4 million. Revenue recognized for the six months ended June 30, 2024 from amounts included in deferred revenue as of December 31, 2023 was $60.1 million. Prior period amounts have been adjusted to correct for identified errors in the calculation of deferred revenue recognized for the six months ended June 30, 2024. Remaining performance obligations (“RPO”) represent the amount of contracted future revenue that has not yet been recognized, including both deferred revenue and non-cancelable contracted amounts that will be invoiced and recognized as revenue in future periods. The Company’s RPO excludes performance obligations from on-demand arrangements as there are no minimum purchase commitments associated with these arrangements, and certain time and materials contracts that are billed in arrears. As of June 30, 2025, the Company’s RPO was $396.9 million, which will be delivered and recognized within the next six years. The Company expects to recognize approximately 63% of the RPO over the next 12 months, 22% of the RPO over the subsequent 13 to 24 months, and the remainder thereafter.
