Revenue from Contract with Customer [Abstract]  



On August 14, 2020, we entered into sublicense and inventory purchase agreements with Taysha Gene Therapies (“Taysha”) relating to a potential gene therapy for CLN1 disease. Under the sublicense agreement, Taysha received worldwide exclusive rights to intellectual property and know-how relating to the research, development and manufacture of the potential gene therapy, which we had referred to as ABO-202. Under the inventory purchase agreement, we sold to Taysha certain inventory and other items related to ABO-202.


We assessed these contracts at contract inception and determined that, under ASC 606, the two contracts would be combined and accounted for a single contract, with a single performance obligation. We assessed the nature of the promised license to determine whether the license has significant stand-alone functionality and evaluated whether such functionality can be retained without ongoing activities of the entity and determined that the license has significant stand-alone functionality. Furthermore, we have no ongoing activities associated with the license to support or maintain the license’s utility. Based on this, we determined that the pattern of transfer of control of the license to the customer was at a point in time.



The transaction price of the contract includes (i) $7.0 million of fixed consideration, (ii) up to $26.0 million of variable consideration in the form of event-based milestone payments, (iii) up to $30.0 million of variable consideration in the form of sales-based milestone payments, and (iv) other royalty-based payments based on net sales. The event-based milestone payments are based on certain development and regulatory events occurring. We evaluated whether the milestone conditions have been achieved and if it is probable that a significant revenue reversal would not occur before recognizing the associated revenue. We determined that these milestone payments are not within our control or the licensee’s control, such as regulatory approvals, and are not considered probable of being achieved until those approvals are received. Accordingly, we have fully constrained the $26.0 million of event-based milestone payments until such time that it is probable that significant revenue reversal would not occur. The sales-based milestone payments and other royalty-based payments are based on a level of sales for which the license is deemed to be the predominant item to which the royalties relate. We will recognize revenue for these payments at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, we have not recognized any sales-based or royalty revenue resulting from this licensing arrangement.


Under this arrangement, we recognized $7.0 million of revenue during the three months ended September 30, 2020, which amount related solely to fixed consideration. In addition, we have $7.0 million of related accounts receivable at September 30, 2020; this receivable was paid by Taysha in October 2020. We do not have any contract assets or contract liabilities as a result of this transaction.
