Equity Investments	Equity Investments (a) Nimbus The Company previously provided collaboration services for Nimbus Therapeutics, LLC ("Nimbus") under the terms of a master services agreement executed on May 18, 2010, as amended. Collaboration agreements are separate from the transaction that resulted in equity ownership and related fees are paid in cash to the Company. Nimbus was previously recorded as an equity method investment under the HLBV method, as the entity is a limited liability company and the Company was determined to have significant influence due to the Company's collaboration with Nimbus on a number of drug discovery targets, as well as the Company's level of ownership in Nimbus. During the period ended September 30, 2023, the Company's equity ownership in Nimbus was diluted to the point that the Company no longer has significant influence over the entity. As the Company no longer has significant influence over Nimbus, after June 30, 2023, the equity investment in Nimbus is valued as a non-marketable equity security. As of December 31, 2024 and 2023, the carrying value of the Nimbus investment was $2,436 and $1,928, respectively. The Company has no obligation to fund Nimbus' losses in excess of its investment. During the year ended December 31, 2024, the Company reported an unrealized gain of $508 on the Nimbus investment. During the year ended December 31, 2023, the company reported a realized gain of $147,213 on the Nimbus investment, which reflected the total cash distribution the Company received from Nimbus on account of Takeda's acquisition of Nimbus Lakshmi, Inc., a wholly-owned subsidiary of Nimbus, and its tyrosine kinase 2 inhibitor NDI-034858, as well as an unrealized gain of $1,928 on the Nimbus investment due to the change in accounting method. The Company reported no gains or losses on the Nimbus investment during the year ended December 2022. (b) Morphic On August 15, 2024, the Company disposed of its equity stake in Morphic Holding, Inc.
