Equity Method And Cost Method Investment [Abstract] |
Other Equity Investments | 6. Other Equity Investments LianBio In October 2019, our subsidiary, BridgeBio Pharma LLC (“BBP LLC”), entered into an exclusivity agreement with LianBio, pursuant to which BBP LLC received equity in LianBio representing a 10% ownership interest. We account for BBP LLC’s equity interest in LianBio under ASC 321 Investments - Equity Securities as an investment in equity securities. For the three months ended March 31, 2023 and 2022, we recorded an unrealized gain of $1.6 million and an unrealized loss of $12.3 million, respectively, for the ongoing mark-to-market adjustments of our investment, see Note 3. Pursuant to a License Agreement entered into in October 2019 between QED and LianBio, QED also received warrants which entitled QED to purchase 10% of the then-fully diluted shares of one of the subsidiaries of LianBio upon achievement of certain contingent development milestones. Changes in fair value of the warrants were not material for the three months ended March 31, 2023 and 2022. In October 2021, the warrants held by QED to purchase shares of one of the subsidiaries of LianBio were converted into the LianBio Warrant, which entitles QED to purchase 347,569 shares of LianBio. The LianBio Warrant is measured at fair value on a recurring basis, with changes in fair value recognized in our condensed consolidated statements of operations as part of “Other expense, net.” The LianBio Warrant, which is presented as part of “Other assets” in our condensed consolidated balance sheets, had a fair value of $0.7 million and $0.6 million as of March 31, 2023 and December 31, 2022, respectively. PellePharm As of April 15, 2021, BridgeBio had been the primary beneficiary of PellePharm as it had power over key decisions that significantly impact PellePharm’s economic performance. BridgeBio also had the obligation to absorb losses or the right to receive benefits from PellePharm that could potentially be significant to PellePharm through its common and preferred stock interest in PellePharm. Accordingly, BridgeBio had consolidated PellePharm during the period April 15, 2021 through December 31, 2022. On January 16, 2023, PellePharm's board of directors authorized the assignment of all PellePharm's assets to PellePharm ABC, LLC for liquidation and distribution under the General Assignment for the Benefit of Creditors (“ABC”). As part of the ABC proceedings, PellePharm's board of directors resigned effective March 6, 2023. The date the board of directors resigned was determined to be a VIE reconsideration event. Based on the changes to PellePharm’s governance structure and composition of the board of directors as a result of the ABC, BridgeBio was no longer the primary beneficiary, as it no longer had the power over key decisions that significantly impact PellePharm’s economic performance. Accordingly, BridgeBio deconsolidated PellePharm effective during the three months ended March 31, 2023 and recognized a loss of $1.2 million which is presented as part of "Other expense, net" on the condensed consolidated statements of operations.
