CMS Actions  
CMS regularly audits the Company’s performance to determine its compliance with CMS’s regulations and its contracts with CMS and to assess the quality of services it provides to Medicare beneficiaries. CMS uses various payment mechanisms to allocate and adjust premium payments to the Company’s and other companies’ Medicare plans by considering the applicable health status of Medicare members as supported by information prepared, maintained and provided by providers. The Company collects claim and encounter data from providers and generally relies on providers to appropriately code their submissions to the Company and document their medical records, including the diagnosis data submitted to the Company with claims. CMS pays increased premiums to Medicare Advantage plans and Medicare PDP plans for members who have certain medical conditions identified with specific diagnosis codes. Federal regulators review and audit the providers’ medical records to determine whether those records support the related diagnosis codes that determine the members’ health status and the resulting risk-adjusted premium payments to the Company. In that regard, CMS has instituted risk adjustment data validation (“RADV”) audits of various Medicare Advantage plans, including certain of the Company’s plans, to validate coding practices and supporting medical record documentation maintained by providers and the resulting risk adjusted premium payments to the plans. CMS may require the Company to refund premium payments if the Company’s risk adjusted premiums are not properly supported by medical record data. The Office of the Inspector General of the HHS (the “OIG”) also is auditing the Company’s risk adjustment-related data and that of other companies. The Company expects CMS and the OIG to continue these types of audits.  
In 2012, CMS revised its audit methodology for RADV audits to determine refunds payable by Medicare Advantage plans for contract year 2011 and forward. Under the revised methodology, among other things, CMS will extrapolate the error rate identified in the audit sample of approximately 200 members to all risk adjusted premium payments made under the contract being audited. For contract years prior to 2011, CMS did not extrapolate sample error rates to the entire contract. As a result, the revised methodology may increase the Company’s exposure to premium refunds to CMS based on incomplete medical records maintained by providers. Since 2013, CMS has selected certain of the Company’s Medicare Advantage contracts for various contract years for RADV audit, and the number of RADV audits continues to increase. The Company is currently unable to predict which of its Medicare Advantage contracts will be selected for future audit, the amounts of any retroactive refunds of, or prospective adjustments to, Medicare Advantage premium payments made to the Company, the effect of any such refunds or adjustments on the actuarial soundness of the Company’s Medicare Advantage bids, or whether any RADV audit findings would require the Company to change its method of estimating future premium revenue in future bid submissions to CMS or compromise premium assumptions made in the Company’s bids for prior contract years, the current contract year or future contract years. Any premium or fee refunds or adjustments resulting from regulatory audits, whether as a result of RADV, Public Exchange related or other audits by CMS, the OIG or otherwise, including audits of the Company’s MLR rebates, methodology and/or reports, could be material and could adversely affect the Company’s operating results, cash flows and/or financial condition.  
Medicare and Medicaid CIDs  
The Company has received CIDs from the Civil Division of the DOJ in connection with a current investigation of the Company’s patient chart review processes in connection with risk adjustment data submissions under Parts C and D of the Medicare program. The Company has been cooperating with the government and providing documents and information in response to these CIDs.  
In May 2017, the Company received a CID from the SDNY requesting documents and information concerning possible false claims submitted to Medicare in connection with reimbursements for prescription drugs under the Medicare Part D program. The Company has been cooperating with the government and providing documents and information in response to this CID.  
Stockholder Matters  
Beginning in February 2019, multiple class action complaints, as well as a derivative complaint, were filed by putative plaintiffs against the Company and certain current and former officers and directors. The plaintiffs in these cases assert a variety of causes of action under federal securities laws that are premised on allegations that the defendants made certain omissions and misrepresentations relating to the performance of the Company’s LTC business unit. The Company and its current and former officers and directors are defending themselves against these claims. Since filing, several of the cases have been consolidated, and the first-filed federal case, City of Miami Fire Fighters’ and Police Officers’ Retirement Trust, et al. (formerly known as Anarkat), was dismissed with prejudice in February 2021. Plaintiffs have appealed that decision to the First Circuit after their motion for reconsideration was denied.
