9. Commitments and Contingencies

Collaborative Agreements, Royalties and Milestone Payments

The Company has committed to make potential future milestone payments and legal fees to third parties as part of licensing and development programs. Payments under these agreements become due and payable only upon the achievement of certain developmental, regulatory and commercial milestones by the Company’s licensees. Because it is uncertain if and when these milestones will be achieved, such contingencies, aggregating up to $6.3 million (assuming one product per contract meets all milestone events) have not been recorded on the accompanying condensed consolidated balance sheets. The Company is unable to determine precisely when and if payment obligations under the agreements will become due as these obligations are based on milestone events, the achievement of which is subject to a significant number of risks and uncertainties.

Contingent Consideration

Pursuant to the Company’s RPAs and CPPAs with Bioasis, Aronora, Kuros and Affitech, the Company has committed to pay the Bioasis Contingent Consideration, the Aronora Royalty Milestones, the Kuros Sales Milestones and the Affitech regulatory and sales milestones. As of June 30, 2022, the estimated fair value of the Bioasis Contingent Consideration is $0.1 million and the estimated fair value of the Affitech Regulatory Milestones is $3.0 million (Note 6). The liability for future Aronora Royalty Milestones, Kuros Sales Milestones and Affitech Sales Milestones will be recorded when the amounts, by product, are estimable and probable. As of June 30, 2022, none of these Aronora Royalty Milestones, Kuros Sales Milestones or Affitech Sales Milestones were assessed to be probable and as such, no liability was recorded on the condensed consolidated balance sheet.
