COMMITMENTS AND CONTINGENCIES	8. COMMITMENTS AND CONTINGENCIES Litigation — On and after March 14, 2012, the Company and certain of its current and former officers and directors and, in some cases, some or all of K-9 Investors, L.P., Apollo Management VII, L.P., Apollo Global Management, LLC and K-9 and Merger Sub were named as defendants in five class action lawsuits filed in the Delaware Court of Chancery which were ultimately consolidated into a single class action (the “Delaware Action”). In the Delaware Action, the plaintiff, on behalf of a putative class of stockholders, sought to enjoin the proposed transaction that was the subject of the Merger Agreement. Other lawsuits were filed in Wisconsin state and federal court — two in the Circuit Court, Civil Division for Dane County, one of which was dismissed by the plaintiff prior to settlement (the surviving action, “Wisconsin State Court Action”), and one in the United States District Court for the Western District of Wisconsin (the “Wisconsin Federal Court Action”). On April 25, 2012, the parties to the Delaware Action and the Wisconsin State Court Action reached an agreement in principle to settle those cases. The proposed settlement, which was subject to court approval, provided for, among other things, the dismissal with prejudice of plaintiffs’ complaints and of all claims asserted therein, that all parties granted all applicable releases of claims against all other parties, and that the parties to the Delaware Action and the Wisconsin State Court Action acknowledged that the plaintiffs and their counsel in those cases would petition the appropriate court or courts for an award of attorneys’ fees and expenses in connection with the cases. Any award of fees and expenses to plaintiffs’ counsel was subject to approval by the appropriate court or courts. Pursuant to an order from the Delaware Court of Chancery, notice to the class was mailed on October 19, 2012. On April 30, 2012, the parties to the Wisconsin Federal Court Action agreed to settle that case, subject to court approval of the proposed class-wide settlement in the Delaware Action and entry of a final order dismissing the Delaware Action in its entirety. Pursuant to their agreement, the parties to the Wisconsin Federal Court Action filed with the court, on April 30, 2012, a stipulation providing that the Wisconsin Federal Court Action be voluntarily dismissed with respect to all defendants and that such dismissal would be with prejudice as to the plaintiff upon the consummation of the settlement of the Delaware Action. On September 27, 2012, the parties to the Delaware Action agreed to settle that case. Pursuant to their agreement, the parties to the Delaware Action filed with the Delaware Court of Chancery on September 27, 2012, a stipulation providing that the Delaware Action be voluntarily dismissed with respect to all defendants and that such dismissal be with prejudice as to the plaintiff. On December 18, 2012, the Delaware Court of Chancery approved the class-wide settlement in the Delaware Action and entered a final order dismissing the Delaware Action in its entirety. It awarded counsel for the plaintiffs in the Delaware Action fees and expenses in the amount of $1,940, which was paid in 2013. The Company, the members of the Board of Directors, Apollo Management VII, L.P., Apollo Global Management, LLC, K-9 and Merger Sub each have denied, and continue to deny, that they committed or attempted to commit any violation of law or breach of fiduciary duty owed to the Company and/or its stockholders, aided or abetted any breach of fiduciary duty, or otherwise engaged in any of the wrongful acts alleged in all of these cases. All of the defendants expressly maintain that they complied with their fiduciary and other legal duties. However, in order to avoid the costs, disruption and distraction of further litigation, and without admitting the validity of any allegation made in the actions or any liability with respect thereto, the defendants concluded that it is desirable to settle the claims against them on the terms reflected in the settlements. We are involved in litigation from time to time in the ordinary course of our business. We do not believe that the outcome of any pending or threatened litigation will have a material adverse effect on our financial condition or results of operations. However, as is inherent in legal proceedings where issues may be decided by finders of fact, there is a risk that unpredictable decisions, materially adverse to the Company, could occur.
