9 Months Ended

Note 13. Earn-Out Milestone Liability

The total aggregate purchase price for the EGEN Acquisition (see Note 8) included potential future earn-out payments contingent upon achievement of certain milestones. The difference between the aggregate $30.4 million in future earn-out payments and the $13.9 million included in the fair value of the acquisition consideration at June 20, 2014 was based on the Company’s risk-adjusted assessment of each milestone (10% to 67%) and utilizing a discount rate based on the estimated time to achieve the milestone (1.5 to 2.5 years). The earn-out milestone liability is fair valued at the end of each quarter and any change in their value will be recognized in the condensed consolidated financial statements.

On March 28, 2019, the Company and EGWU, Inc. entered into an amendment to its purchase agreement (“Amended Asset Purchase Agreement”), whereby payment of the earnout milestone liability related to the Ovarian Cancer Indication of $12.4 million had been modified. The Company has the option to make the payment as follows:

a)	$7.0 million in cash within 10 business days of achieving the milestone; or
b)	$12.4 million in cash, common stock of the Company, or a combination of either, within one year of achieving the milestone.

At December 31, 2022, the Company wrote off the carrying value of the earn-out milestone liability as a result of the requirements not being achieved and recognized a non-cash gain of $5.4 million during 2022 as a result of the change in the fair value of the earn-out milestone liability.
