As discussed in Note 2, on June 17, 2020, the Company entered into the Original Merger Agreement, which meets the definition of a fundamental transaction as defined by the warrant agreements. Therefore, the Company adjusted the likelihood and timing of its fundamental transaction assumptions when calculating the fair values of the liability-classified warrants as of September 30, 2020.
Changes in the fair value of the warrant liabilities, carried at fair value, reported as “unrealized gain (loss) gain on fair value of warrants” in the statement of operations:
