From time to time, the Company is subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings and claims individually or in the aggregate cannot be predicted with certainty, the Company has not had a history of outcomes to date that have been material to the statement of operations and does not believe that any of these proceedings or other claims will have a material adverse effect on its consolidated financial condition, results of operations or cash flows.

In 2017, the former shareholders of Miconex disputed the Company’s determination that Miconex failed to achieve the specified performance target applicable to the potential cash “earn-out” payments under the acquisition agreement for the second annual performance period ended July 2017 (the “Performance Target”). The Company expects the dispute to be resolved pursuant to the dispute resolution provisions of the acquisition agreement. The Company believes that Miconex did not achieve the Performance Target, and therefore no earn-out payment is owed by the Company. However, there can be no assurance that the dispute will be resolved in the Company’s favor. If the dispute is resolved adversely to the Company, the Company would expect to record a charge to Interest and Other Income (Expense), of not more than $1.0 million.
