Shareholders' Equity [Abstract] |
Stockholders' Equity Note Disclosure [Text Block] | Shareholders' Equity Regulatory Capital and Dividend Restrictions The Company’s regulated insurance and health maintenance organization (HMO) subsidiaries are subject to regulations and standards in their respective jurisdictions. These standards, among other things, require these subsidiaries to maintain specified levels of statutory capital, as defined by each jurisdiction, and restrict the timing and amount of dividends and other distributions which may be paid to their parent companies. In the United States, most of these state regulations and standards are generally consistent with model regulations established by the National Association of Insurance Commissioners. These standards generally permit dividends to be paid from statutory unassigned surplus of the regulated subsidiary and are limited based on the regulated subsidiary’s level of statutory net income and statutory capital and surplus. These dividends are referred to as “ordinary dividends” and generally may be paid without prior regulatory approval. If the dividend, together with other dividends paid within the preceding twelve months, exceeds a specified statutory limit or is paid from sources other than earned surplus, it is generally considered an “extraordinary dividend” and must receive prior regulatory approval. For the year ended December 31, 2021, the Company’s domestic insurance and HMO subsidiaries paid their parent companies dividends of $8.0 billion, including $4.7 billion of extraordinary dividends. For the year ended December 31, 2020, the Company’s domestic insurance and HMO subsidiaries paid their parent companies dividends of $8.3 billion, including $4.2 billion of extraordinary dividends. The Company's global financially regulated subsidiaries had estimated aggregate statutory capital and surplus of $30.7 billion as of December 31, 2021. The estimated statutory capital and surplus necessary to satisfy regulatory requirements of the Company's global financially regulated subsidiaries was approximately $13.0 billion as of December 31, 2021. Optum Bank must meet minimum capital requirements of the Federal Deposit Insurance Corporation (FDIC) under the capital adequacy rules to which it is subject. At December 31, 2021, the Company believes Optum Bank met the FDIC requirements to be considered “Well Capitalized.” Share Repurchase Program Under its Board of Directors’ authorization, the Company maintains a share repurchase program. The objectives of the share repurchase program are to optimize the Company’s capital structure and cost of capital, thereby improving returns to shareholders, as well as to offset the dilutive impact of share-based awards. Repurchases may be made from time to time in open market purchases or other types of transactions (including prepaid or structured share repurchase programs), subject to certain Board restrictions. In June 2018, the Board renewed the Company’s share repurchase program with an authorization to repurchase up to 100 million shares of its common stock. A summary of common share repurchases for the years ended December 31, 2021 and 2020 is as follows:
|  | Years Ended December 31,
(in millions, except per share data) |  | 2021 |  | 2020

Dividends In June 2021, the Company’s Board of Directors increased the Company’s quarterly cash dividend to shareholders to an annual rate of $5.80 compared to $5.00 per share, which the Company had paid since June 2020. Declaration and payment of future quarterly dividends is at the discretion of the Board and may be adjusted as business needs or market conditions change.
