Related Party Transactions [Abstract] |
Related Parties | 12. Related Parties Corporate expenses prior to the Separation represent shared costs of the Former Parent that have been allocated to the Company based on a systematic and rational methodology and are reflected as expenses in these unaudited condensed consolidated financial statements. These amounts include, but are not limited to, items such as general management and executive oversight, costs to support the Company’s information technology infrastructure, facilities, compliance, human resources, legal and finance functions, risk management, and share-based compensation administration, all of which support the operations of the Former Parent as a whole. Corporate expense allocations in the periods prior to the Separation were generally allocated to the Company based on proportional cost allocation methods using headcount, square footage, or proportional hours worked supporting the Company and other organizational activities, as applicable, which are considered to be reasonable reflections of the utilization of services provided or benefit received by the Company during the periods presented. Total corporate expense allocations from the Former Parent for the periods prior to the Separation in general and administrative expenses were $3.7 million during the three months ended March 31, 2023. Total corporate expense allocations from the Former Parent for the periods prior to the Separation in R&D expenses were $40.4 million during the three months ended March 31, 2023. The Former Parent assumed all of the outstanding accrued liabilities and accounts payable related to the oncology business as of the date of the Separation. Management considers the allocation methodologies used to be reasonable and appropriate reflections of the related expenses attributable to the Company for purposes of the unaudited condensed consolidated financial statements; however, the expenses reflected in these unaudited condensed consolidated financial statements may not be indicative of the actual expenses that would have been incurred during the periods presented if the Company had operated as a standalone entity. In addition, the expenses reflected in the unaudited condensed consolidated financial statements may not be indicative of expenses that will be incurred in the future by the Company. See Note 1, Organization and Description of Business, for details of the Company’s cash and financing arrangements. As of the date these unaudited condensed consolidated financial statements were available for issuance, there were no existing intercompany debt or other financing agreements in place with the Former Parent. As of March 31, 2024, the Company had a receivable from the Former Parent of $1.9 million pursuant to the transition services agreements. During the three months ended March 31, 2024, the Company received $4.9 million from the Former Parent and paid $4.0 million to the Former Parent pursuant to the transition services agreements. See Note 2, Basis of Presentation and Summary of Significant Accounting Policies, for additional information on the preparation and basis of presentation of these consolidated financial statements, including the treatment of certain R&D costs not directly attributable to individual programs, cash and cash equivalents, share-based compensation, and 401(k) Plan expenses. As of the date of the Separation, the Former Parent is no longer a related party to the Company.
