13. 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 milestones events) have not been recorded on the accompanying 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 royalty and commercial payment purchase agreements 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. The Company recorded $0.1 million and $8.0 million for the Bioasis Contingent Consideration and the Affitech Regulatory Milestones, respectively, which, represents the estimated fair value of these potential future payments at the inception of the respective agreements. The contingent

consideration is remeasured at fair value at each reporting period, with changes in fair value recorded in other (expense) income, net. As of December 31, 2021, there were no changes in the estimated fair value of the Bioasis Contingent Consideration and the Affitech Sales Milestones from the initial value. 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 December 31, 2021, 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 consolidated balance sheet.
