COMMITMENTS AND CONTINGENCIES Bank Guarantee In March 2015, an operating subsidiary of Acacia entered into a standby letter of credit and guarantee arrangement ( Guarantee ) with a bank in the amount of $10.7 million , for purposes of enforcing a court ruling in a German patent court granting an injunction against the defendants in the related patent infringement case. An injunction is an equitable remedy in the form of a court order that compels the defendant(s) to cease marketing, offering for sale or importing applicable infringing products into applicable jurisdiction(s). Under German law, in order to enforce the injunction granted by the court, a Guarantee is required to be furnished by our operating subsidiary, the plaintiff in the case, for potential payment to the defendants of any applicable claims which may be incurred by the defendants as a result of the enforcement of the injunction, only in the event that the aforementioned court ruling is subsequently successfully appealed by the defendants or otherwise amended. The Guarantee is required to be issued unlimited with respect to time, until appropriately extinguished in accordance with German law. The Guarantee will be extinguished when a relevant extinguishment order by the court having jurisdiction takes effect, typically occurring when the related infringement case has been settled or a final non-appealable decision has been issued by the court. The Guarantee is secured by a cash deposit at the contracting bank totaling $10.7 million , which is classified as restricted cash in the March 31, 2015 balance sheet. The Guarantee expires on April 10, 2016, however, it is automatically extended without amendment for a period of one (1) year from the present or any future expiration date, unless at least 30 days prior to any expiration date, the Guarantee is extinguished in accordance with German law. The Guarantee facility fee is 1.15% per year, and the related expense is included in the statement of operations. Patent Enforcement Certain of Acacia s opera
