Litigation Matters

Other than below and lawsuits we have historically brought to enforce our patent rights, we are not a party to any material pending legal proceedings other than that which arise in the ordinary course of business.  We believe that any liability that may ultimately result from the resolution of these matters will not, individually or in the aggregate, have a material adverse effect on our financial position or results of operations.

On November 5, 2018, a putative shareholder derivative complaint was filed in the Court of Chancery of the State of Delaware, captioned Howland v. Kumar et al., C.A. No. 2018-0804-KSJM, that alleges claims for breach of fiduciary duty and unjust enrichment.  The complaint named as defendants certain of the Company’s current and former officers and directors, and the Company is named solely as a nominal defendant.  The Company has certain indemnification obligations to the current and former officers and directors named as defendants in the suit, and the attorney fees incurred for this matter are currently being funded by the Company and through available D&O insurance.  The complaint seeks, on behalf of the Company, a declaration that the defendant officers and directors breached their fiduciary duties, unspecified damages, certain changes to the Company’s internal procedures, and an award of the plaintiff’s attorneys’ fees and costs.  The defendants moved to dismiss the complaint on November 29, 2018, which motion is still pending before the Court of Chancery.  Due to the early nature of the complaint and that the complaint does not specify a dollar amount of damages, we cannot make a reasonable estimate of potential losses at this time.
