Commitments and Contingencies	Note 8 – Commitments and Contingencies In the ordinary course of business, we are at times subject to various legal proceedings and disputes. We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions, if any, are reviewed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. We currently are not a party to any legal proceedings, the adverse outcome of which, in management’s opinion, individually or in the aggregate, would have a material adverse effect on our consolidated financial condition or results of operations. Humanigen Arbitration On December 17, 2021, we filed a Demand for Arbitration claiming more than $20.5 million in damages against Humanigen, Inc. (“Humanigen”) with the American Arbitration Association (“AAA”) entitled, Avid Bioservices, Inc. v. Humanigen, Inc. (AAA Case No. 01-21-0018-0523). The Demand contains three claims for: (1) breach of contract concerning the process development and manufacturing master services agreement (“MSA”); (2) anticipatory breach of contract concerning the capacity expansion and contribution/commitment letter (“Letter Agreement”); and (3) trade libel and commercial disparagement. On January 6, 2022, Humanigen filed an Answer to our Demand, denying the allegations and asserting affirmative defenses. On July 1, 2022, Humanigen filed its counterclaims against us in the form of a complaint in the Orange County Superior Court (Case No. 30-2022-01268184) alleging three claims for (1) breach of the MSA seeking return or reimbursement of the amounts Humanigen paid us before cancelling the MSA, (2) declaratory relief that Humanigen has no remaining obligations under the Letter Agreement, and (3) unfair business practices. On July 19, 2022, we filed a motion with the state court to compel all claims by Humanigen against us to arbitration before the AAA. On October 17, 2022, the state court granted our motion to compel all of Humanigen’s claims against us to arbitration and denied Humanigen’s motion to stay the arbitration. As a result of the court having granted our motion, on November 3, 2022, Humanigen filed its Demand for Arbitration realleging the breach of the MSA and unfair business practices claims which it had initially filed in state court. On November 10, 2022, we filed an Answer to Humanigen’s Demand, denying the allegations and asserting affirmative defenses. On February 21, 2023, we entered into a Confidential Settlement and Mutual Releases Agreement with Humanigen resolving the arbitration proceeding and all disputes between the parties.
