Receivables [Abstract]
RECEIVABLES	6. RECEIVABLES The accounts receivable balance as of December 31, 2021 was $21.0 million, comprised primarily of a $20 million milestone achieved in December 2021 due to F. Hoffmann-La Roche Ltd and Hoffmann-La Roche Inc. (collectively, “Roche”) initiating a Phase II clinical trial in the fourth quarter of 2021. In January 2022 the payment of $20 million was received. Additionally, in June 2021, the Qilu License Agreement was recognized by Shandong Province, Bureau of Science and Technology as a “Technology Transfer”. As such, the Company recorded $0.9 million of revenue and accounts receivable for the additional purchase price resulting from Qilu’s obligation to pay the Company an amount equal to its recovery of value-added tax (“VAT”). The accounts receivable balance as of September 30, 2022 was zero. The other receivables balance as of September 30, 2022 was $14.3 million compared to $3.5 million as of December 31, 2021. The increase of $10.8 million was primarily driven by expected insurance recovery of $13.4 million related to the preliminary settlements of the Securities Litigation and Derivative Litigation (as defined in Note 10. “Commitments and Contingencies” below). This amount was partially offset by the receipt of $2.4 million for German VAT recovery in the first half of 2022, related to drug substance sent to Baxter in 2020 and 2019 and other individually immaterial changes of $0.2 million.	6.
