Note 11. Commitments and Contingencies Contingent Milestone Payments The Company has entered into strategic business agreements for the development and marketing of finished dosage form pharmaceutical products with various pharmaceutical development companies. Each strategic business agreement includes a future payment schedule for contingent milestone payments and in certain strategic business agreements, minimum royalty payments. The Company will be responsible for contingent milestone payments and minimum royalty payments to these strategic business partners based upon the occurrence of future events. Each strategic business agreement defines the triggering event of its future payment schedule, such as meeting product development progress timelines, successful product testing and validation, successful clinical studies, and various U.S. Food and Drug Administration and other regulatory approvals. Supply Agreement Obligations The Company is engaged in various supply agreements with third parties which obligate the Company to purchase various API or finished products at contractual minimum levels. None of these agreements are individually or in the aggregate material to the Company. Further, the Company does not believe that any of the purchase obligations represent levels above that of normal business demands as of March 31, 2020. Legal Proceedings The Company is a party in legal proceedings and potential claims arising from time to time in the ordinary course of its business. The amount, if any, of ultimate liability with respect to such matters cannot be determined. Despite the inherent uncertainties of litigation, management of the Company believes that the ultimate disposition of such proceedings and exposures will not have a material adverse impact on the financial condition, results of operations, or cash flows of the Company. On February 16, 2018, the Company received FDA approval for its amantadine extended release tablets under the trade name OSMOLEX ER. On that same date the Company filed in the Federal District Court for the District of Delaware a Complaint for Declaratory Judgment of Noninfringement of certain patents owned by Adamas Pharmaceuticals, Inc. (Osmotica Pharmaceutical US LLC and Vertical Pharmaceuticals, LLC vs. Adamas Pharmaceuticals, Inc. and Adamas Pharma, LLC). Adamas was served with the Complaint on February 21, 2018. Adamas filed an answer on April 13, 2018 denying the allegations in the Complaint and reserving the ability to raise counterclaims as the litigation progresses. On September 20, 2018, Adamas filed an amended answer to the Companys Complaint for Declaratory Judgment of Noninfringement, with counterclaims alleging infringement of certain patents included in the Companys Complaint and requesting that the court grant Adamas damages, injunctive relief and attorneys fees. The action is ongoing, but was stayed on May 23, 2019 at the parties joint request. On April 30, 2019, Osmotica Pharmaceuticals plc was served with a complaint in an action entitled Leo Shumacher, et al., v. Osmotica Pharmaceuticals plc, et al ., Superior Court of New Jersey, Somerset County No. SOM-L-000540-19. On May 10, 2019, a Complaint entitled Jeffrey Tello, et al., v. Osmotica Pharmaceuticals plc, et al., Superior Court of New Jersey, Somerset County No. SOM-L-000617-19 was filed in the same court as the Shumacher action. The complaints name Osmotica Pharmaceuticals plc, certain of its directors and officers and the underwriters of its initial public offering as defendants in putative class actions alleging violations of Sections 11 and 15 of the Securities Act of 1933 related to the disclosures contained in the registration statement and prospectus used for the Companys initial public offering of ordinary shares. On July 22, 2019, Plaintiffs filed an Amended Complaint consolidating the two actions, reiterating the previously pled allegations and adding an additional individual defendant. The Company disputes the allegations in the complaint and intends to vigorously defend against the action. However, this litigation matter is still in an early stage and there is no assurance that the Company will be successful in its defense or that insurance will be available or adequate to fund any settlement or judgment or the litigation costs of the action, which could adversely affect the Companys results of operations and financial condition. There is no loss that is probable or reasonably estimatable as of March 31, 2020.
