Regulatory Issues The managed healthcare industry is subject to numerous laws and regulations. The subjects of such laws and regulations cover, but are not limited to, matters such as licensure, accreditation, government healthcare program participation requirements, information privacy and security, reimbursement for patient services, and Medicare and Medicaid fraud and abuse. Over the past several years, government activity has increased with respect to investigations and/or allegations concerning possible violations of fraud and abuse and false claims statutes and/or regulations by healthcare organizations and insurers. Entities that are found to have violated these laws and regulations may be excluded from participating in government healthcare programs, subjected to fines or penalties or required to repay amounts received from the government for previously billed patient services. Compliance with such laws and regulations can be subject to future government review and interpretation, as well as regulatory actions unknown or unasserted at this time. In addition, regulators of certain of the Company’s subsidiaries may exercise certain discretionary rights under regulations including increasing their supervision of such entities, requiring additional restricted cash or other security or seizing or otherwise taking control of the assets and operations of such subsidiaries. Legal The Company’s operating activities entail significant risks of liability. From time to time, the Company is subject to various actions and claims arising from the acts or omissions of its employees, network providers or other parties. In the normal course of business, the Company receives reports relating to deaths and other serious incidents involving patients whose care is being managed by the Company. Such incidents occasionally give rise to malpractice, professional negligence and other related actions and claims against the Company or its network providers. Many of these actions and claims received by the Company seek substantial damages and therefore require the Company to incur significant fees and costs related to their defense. The Company is also subject to or party to certain class actions and other litigation and claims relating to its operations or business practices. In the opinion of management, the Company has recorded reserves that are adequate to cover litigation, claims or assessments that have been or may be asserted against the Company, and for which the outcome is probable and reasonably estimable. Management believes that the resolution of such litigation and claims will not have a material adverse effect on the Company’s financial condition or results of operations; however, there can be no assurance in this regard.
