Litigation	Note 11. Litigation On June 21, 2012, a purported shareholder of the Company filed a class action complaint against the Company, our directors and an executive officer of the Company, Sonus and Sonus Merger Subsidiary in connection with the proposed merger.

The action is captioned Rogers v. Keating, et al., Case No. RG12638516, and is pending in the Superior Court of California for Alameda County. The Bruno and Rogers complaints allege that the defendants breached and/or aided and abetted the breach of their fiduciary duties to our shareholders, by seeking to sell the company through an allegedly unfair process and allegedly for an unfair price and on unfair terms.

As is common in this type of litigation, additional lawsuits based upon similar allegations concerning the proposed merger may be filed in the future, in the same or other courts. The Company believes the complaints' allegations have no merit, and intends to defend against them vigorously. However, all litigation is inherently uncertain, and there can be no assurance that the Company's defense of these or similar actions will be successful. The Company has not accrued any amounts related to these complaints, as it believes that a negative outcome is not probable. A subsidiary of the Company, Quintum Technologies, LLC (Quintum), was party, by interpleader, to three related lawsuits in Greece filed by Lexis SA, a former distributor of Quintum products in Greece. The underlying lawsuits, the first of which was filed in 2006, were cancelled due to the fact that the originating plaintiffs waived their rights against Lexis. Since a negative outcome is therefore not probable, the Company has not accrued any amounts related to this matter. As Lexis has not yet formally waived its rights against Quintum, hearings on the matter between Lexis and Quintum remain on calendar and are scheduled for January 2015, but the Company believes the scheduled hearings may not ever occur. The Company is the subject of a complaint filed on June 7, 2012, by AIM-IP LLC in the U.S. District Court for the Central District of California. The complaint alleges infringement of a patent relating to the G.729 audio data compression algorithm. The Company believes that it has various defenses to the complaint, although legal proceedings are subject to inherent uncertainties and unfavorable rulings could occur. The Company has not accrued an amount relating to this matter as the amount of loss cannot be reasonably estimated. In addition to the above, the Company is involved in various legal proceedings from time to time in the normal course of its business.
