In 2010, a jury found in favor of the Company and our insurers. Sonitrol appealed the judgment to the Colorado Appellate Court and on July 19, 2012, the Appellate Court upheld the trial court's ruling on two of the three issues being appealed but set aside the judgment and remanded the case back to the District Court for trial on the sole issue of damages. The Appellate Court's ruling was appealed by Sonitrol to the Colorado Supreme Court on September 21, 2012.

Any monetary recovery from the lawsuit would be recognized only if and when it is finally paid to the Company. We are subject to certain legal proceedings, claims, investigations and administrative proceedings in the ordinary course of our business. We make a provision for a liability when it is both probable that the liability has been incurred and the amount of the liability can be reasonably estimated.
