Termination of Merger with Illumina [Abstract]
Termination of Merger with Illumina	NOTE 4. TERMINATION OF MERGER WITH ILLUMINA On November 1, 2018, we entered into an Agreement and Plan of Merger (as amended, the “Illumina Merger Agreement”) with Illumina, Inc. (“Illumina”) and FC Ops Corp., a wholly owned subsidiary of Illumina (“Illumina Merger Sub”). On January 2, 2020, we, Illumina and Illumina Merger Sub, entered into an agreement to terminate the Merger Agreement (the “Termination Agreement”). Continuation Advances from IlluminaAs part of the Termination Agreement, Illumina paid us cash payments (“Continuation Advances”) of $18.0 million during the fourth quarter of 2019 and $34.0 million during the first quarter of 2020. We recorded the $34.0 million as part of other income in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) for the nine months ended September 30, 2020. Up to the full $52.0 million of Continuation Advances paid to us were repayable without interest to Illumina if, within two years of March 31, 2020, we entered into, or consummated a Change of Control Transaction or raised at least $100 million in a single equity or debt financing (that may have multiple closings), with the amount repayable dependent on the amount raised by us. Resulting from the issuance and sale of $900 million of 1.50% Convertible Senior Notes due February 15, 2028, $52.0 million of Continuation Advances were paid without interest to Illumina in February 2021 and recorded as other expense in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) for the nine months ended September 30, 2021. Please refer to Note 5. Summary of Significant Accounting Policies for the accounting treatment of the Continuation Advances.Reverse Termination Fee from IlluminaAs part of the Termination Agreement, Illumina paid us a $98.0 million termination fee (the “Reverse Termination Fee”), from which we paid our financial advisor associated fees of $6.0 million in April 2020. Pursuant to the Termination Agreement, in the event that, on or prior to September 30, 2020, we entered into a definitive agreement providing for, or consummated, a Change of Control Transaction, then we may have been required to repay the Reverse Termination Fee (without interest) to Illumina in connection with the consummation of such Change of Control Transaction. As indicated in ASC 450, Contingencies, a gain contingency usually is not recognized in the financial statements until the period in which all contingencies are resolved and the gain is realizable. As such, we deferred the gain from the Reverse Termination Fee from Illumina until the date when the associated contingency lapsed. On October 1, 2020, the contingency clauses lapsed and we recorded the $98.0 million as a part of other income in the fourth quarter of 2020.
