We are a party to various legal actions, proceedings, and claims (some of which are not insured), and regulatory and other governmental audits and investigations in the ordinary course of our business. We cannot predict the ultimate outcome of pending litigation, proceedings, and regulatory and other governmental audits and investigations. These matters could potentially subject us to sanctions, damages, recoupments, fines, and other penalties. The Department of Justice, CMS, or other federal and state enforcement and regulatory agencies may conduct additional investigations related to our businesses in the future that may, either individually or in the aggregate, have a material adverse effect on our business, financial position, results of operations, and liquidity. Healthcare providers are subject to lawsuits under the qui tam provisions of the federal False Claims Act. Qui tam lawsuits typically remain under seal for some time while the government decides whether or not to intervene on behalf of a private qui tam plaintiff (known as a relator) and take the lead in the litigation. These lawsuits can involve significant monetary damages and penalties and award bounties to private plaintiffs who successfully bring the suits. We have been a defendant in these cases in the past and may be named as a defendant in similar cases from time to time in the future.
