We are subject to litigation arising in the ordinary course of our business, including litigation principally relating to professional liability. There can be no assurance that our insurance coverage and self-insured liabilities will be adequate to cover all liabilities occurring out of such claims. From time to time, we receive requests for information from government agencies in connection with their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. We review such requests and notices and take appropriate action. We have been subject to certain requests for information and investigations and could be subject to such requests for information and investigations in the future. In the opinion of management, we are not engaged in any legal proceedings that we expect will have a material adverse effect on our business, financial condition, cash flows or results of our operations.
