Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Regulatory Capital Requirements and Dividend Restrictions Our health plans, which are generally operated by our respective wholly owned subsidiaries in those states, are subject to state laws and regulations that, among other things, require the maintenance of minimum levels of statutory capital, as defined by each state. The National Association of Insurance Commissioners (“NAIC”), has adopted rules which, if implemented by the states, set minimum capitalization requirements for insurance companies, HMOs, and other entities bearing risk for healthcare coverage. The requirements take the form of risk-based capital (“RBC”) rules which may vary from state to state. Regulators in some states may also enforce capital requirements that require the retention of net worth in excess of amounts formally required by statute or regulation. All of the states in which our health plans operate, except California, Florida, Massachusetts and New York, have adopted the RBC rules. The RBC rules, if adopted by California, Florida, Massachusetts or New York, could increase the minimum capital required for those states. Our Massachusetts health plan, acquired on December 31, 2020, maintains a $35 million performance bond, effective through December 31, 2021, to partially satisfy minimum net worth requirements in that state. Statutes, regulations and informal capital requirements also restrict the timing, payment, and amount of dividends and other distributions that may be paid to us as the sole stockholder. To the extent our subsidiaries must comply with these regulations, they may not have the financial flexibility to transfer funds to us. Based on current statutes and regulations, the net assets in these subsidiaries (not including the Magellan Complete Care subsidiaries and after intercompany eliminations), which may not be transferable to us in the form of loans, advances, or cash dividends was approximately $1,960 million at December 31, 2020, and $1,810 million at December 31, 2019. We estimate the Magellan Complete Care subsidiaries’ net assets that may not be transferable amounted to approximately $420 million at December 31, 2020. Because of the statutory restrictions that inhibit the ability of our health plans to transfer net assets to us, the amount of retained earnings readily available to pay dividends to our stockholders is generally limited to cash, cash equivalents and investments held by the parent company—Molina Healthcare, Inc. Such cash, cash equivalents and investments amounted to $644 million and $997 million as of December 31, 2020 and 2019, respectively. As of December 31, 2020, our health plans (not including the Magellan Complete Care subsidiaries) had aggregate statutory capital and surplus of approximately $2,020 million compared with the required minimum aggregate statutory capital and surplus of approximately $1,310 million. As of December 31, 2020, the aggregate and minimum capital and surplus of the Magellan Complete Care subsidiaries amounted to approximately $420 million and $230 million, respectively. The aggregate capital and surplus of our wholly owned subsidiaries was in excess of these minimum capital requirements as of December 31, 2020. We have the ability and commitment to provide additional capital to each of our health plans when necessary to ensure that statutory capital and surplus continue to meet regulatory requirements. COVID-19 Pandemic We continue to monitor and assess the estimated operating and financial impact of the COVID-19 pandemic, and as it evolves, we continue to process, assemble, and assess member utilization information. We believe that our cash resources, borrowing capacity available under the Credit Agreement, and cash flow generated from operations will be sufficient to withstand the financial impact of the pandemic, and will enable us to continue to support our operations, regulatory requirements, debt repayment obligations, and capital expenditures for the foreseeable future. Legal Proceedings The healthcare industry is subject to numerous laws and regulations of federal, state, and local governments. Compliance with these laws and regulations can be subject to government review and interpretation, as well as regulatory actions unknown and unasserted at this time. Penalties associated with violations of these laws and regulations include significant fines and penalties, exclusion from participating in publicly funded programs, and the repayment of previously billed and collected revenues. We are involved in legal actions in the ordinary course of business including, but not limited to, various employment claims, vendor disputes and provider claims. Some of these legal actions seek monetary damages, including claims for punitive damages, which may not be covered by insurance. We review legal matters and update our estimates of reasonably possible losses and related disclosures, as necessary. We have accrued liabilities for legal matters for which we deem the loss to be both probable and reasonably estimable. These liability estimates could change as a result of further developments of the matters. The outcome of legal actions is inherently uncertain. An adverse determination in one or more of these pending matters could have an adverse effect on our consolidated financial position, results of operations, or cash flows. Kentucky RFP. On September 4, 2020, Anthem Kentucky Managed Care Plan, Inc. brought an action in Franklin County Circuit Court against the Kentucky Finance and Administration Cabinet, the Kentucky Cabinet for Health and Family Services and all of the winning bidder health plans, including Molina Healthcare of Kentucky, Inc., Civil Action No. 20-CI-00719. In its action, Anthem requested that the court disqualify Molina Healthcare of Kentucky, find that the Kentucky RFP scoring was erroneous and violated procedures or was arbitrary and capricious, set aside the contract awards and conduct a new RFP evaluation process, and award injunctive relief, including stopping the implementation of the contracts awarded under the RFP. On September 28, 2020, the court issued a temporary restraining order preserving the status quo, and on October 23, 2020, the court issued a temporary injunction directing that the RFP readiness review and open enrollment proceed with six health plans, including both Anthem and Molina Healthcare. On December 22, 2020, the court granted a motion by UnitedHealthcare of Kentucky LTD. to assert a cross-claim against the Kentucky Cabinet for Health and Family Services, which sought in part a disqualification of Anthem or Molina Healthcare and a declaratory judgment that the Kentucky Medicaid program proceed with only five health plans. On December 23, 2020, Humana Health Plan, Inc. brought a separate action against the Commonwealth of Kentucky and the winning bidder health plans, including Molina Healthcare of Kentucky, Civil Action 20-CI-00987. On January 11, 2021, both actions were consolidated before the Franklin County Circuit Court. Humana requests a declaratory judgment finding that the Commonwealth violated the Medicaid contract by allocating Passport members to Molina Healthcare for 2021 so that Passport members would instead be allocated to Humana and other winning health plans, or, in the alternative, monetary damages from the Commonwealth. Molina Healthcare believes it has meritorious defenses to the claims of Anthem, United, and Humana, and intends to vigorously defend its position, including its twice being a winning bidder of the Kentucky Medicaid RFP, and its protection of the continuity of care for Passport Medicaid members. This matter remains subject to significant additional legal proceedings, and no assurances can be given regarding the ultimate outcome. Under the court’s temporary injunction, Molina Healthcare of Kentucky continues to operate under its contract and provide care to Kentucky Medicaid members.
