Regulated Operations [Abstract]
Regulatory Requirements Text Block	Regulatory Requirements All of our health plans as well as our insurance subsidiaries ("regulated subsidiaries") are required to maintain minimum capital standards and certain restricted accounts or assets, in accordance with legal and regulatory requirements. For example, under the Knox-Keene Health Care Service Plan Act of 1975, as amended, our California health plans are regulated by the California Department of Managed Health Care ("DMHC") and must comply with certain minimum capital or tangible net equity requirements. Our non-California health plans as well as our insurance subsidiaries must comply with their respective state's minimum regulatory capital requirements. In addition, in California and in certain other jurisdictions, our regulated subsidiaries are required to maintain minimum investment amounts for the restricted use of the regulators in certain limited circumstances. See the “Restricted Assets” section in Note 2 for additional information. In addition, as necessary, we make contributions to and issue standby letters of credit on behalf of our regulated subsidiaries to meet risk based capital ("RBC") or other statutory capital requirements under various state laws and regulations, and to meet the capital standards of credit rating agencies. During the year ended December 31, 2012, the parent made capital contributions of $17.6 million to a subsidiary. Certain of our subsidiaries report their accounts in conformity with accounting practices prescribed or permitted by state insurance regulatory authorities, or statutory accounting. These subsidiaries are domiciled in various jurisdictions and prepare statutory financial statements in accordance with accounting practices prescribed or permitted by the respective jurisdictions' insurance regulators. Prescribed statutory accounting practices are set forth in a variety of publications of the National Association of Insurance Commissioners ("NAIC") as well as state laws, regulations and general administrative rules. The NAIC has developed a codified version of the statutory accounting principles, designed to foster more consistency among the states for accounting guidelines and reporting. Statutory reporting varies in certain respects from GAAP. Typical differences of statutory reporting as compared to GAAP reporting are the reporting of fixed maturity securities at amortized cost, not recognizing certain assets including those that are non-admitted for statutory purposes and certain reporting classifications. Statutory-basis capital and surplus of our health plan subsidiaries was $143.8 million and $159.5 million at December 31, 2012 and 2011, respectively. Statutory-basis net income of our health plan subsidiaries was approximately $44 thousand, $4.3 million and $17.6 million for the years ended December 31, 2012, 2011 and 2010, respectively. Our subsidiaries that are regulated by DMHC report their accounts in conformity with GAAP. GAAP equity of our DMHC regulated subsidiaries was $1.2 billion and $1.2 billion at December 31, 2012 and 2011, respectively. GAAP net income of our DMHC regulated subsidiaries was $122.1 million, $181.1 million and $146.9 million for the years ended December 31, 2012, 2011 and 2010, respectively. We are a holding company and, therefore, our ability to pay dividends depends on distributions received from our subsidiaries, which are subject to regulatory capital requirements and other requirements of state law and regulation. As a result of these regulatory capital requirements and other requirements of state law and regulation, certain regulated subsidiaries are subject to restrictions on their ability to make dividend payments, loans or other transfers of cash to us, or their ability to do so is conditioned upon prior regulatory approval or non-objection. Such restrictions, unless amended or waived, limit the use of any cash generated by these subsidiaries to pay our obligations or make dividends. The maximum amount of dividends that can be paid by the regulated subsidiaries to us without prior approval of the state regulatory authorities is subject to restrictions relating to statutory surplus, statutory income and tangible net equity. See Note 6 for further discussion of restrictions on our ability to pay dividends to our stockholders that are contained in our revolving credit facility. Based on operations as of December 31, 2012, the amount of statutory capital and surplus or net worth of our regulated subsidiaries necessary to satisfy regulatory requirements was $410.6 million in the aggregate. As of December 31, 2012, the amount of capital and surplus or net worth that was unavailable for the payment of dividends or return of capital to us was approximately $410.6 million in the aggregate. As of December 31, 2012, the amount of restricted net assets of our regulated subsidiaries was approximately $163.0 million in the aggregate. Management believes that as of December 31, 2012 all of our active regulated subsidiaries met their respective regulatory requirements relating to maintenance of minimum capital standards and restricted accounts or assets in all material respects.

Regulatory Requirements

All of our health plans as well as our insurance subsidiaries ("regulated subsidiaries") are required to maintain minimum capital standards and certain restricted accounts or assets, in accordance with legal and regulatory requirements. For example, under the Knox-Keene Health Care Service Plan Act of 1975, as amended, our California health plans are regulated by the California Department of Managed Health Care ("DMHC") and must comply with certain minimum capital or tangible net equity requirements. Our non-California health plans as well as our insurance subsidiaries must comply with their respective state's minimum regulatory capital requirements. In addition, in California and in certain other jurisdictions, our regulated subsidiaries are required to maintain minimum investment amounts for the restricted use of the regulators in certain limited circumstances. See the “Restricted Assets” section in Note 2 for additional information.

In addition, as necessary, we make contributions to and issue standby letters of credit on behalf of our regulated subsidiaries to meet risk based capital ("RBC") or other statutory capital requirements under various state laws and regulations, and to meet the capital standards of credit rating agencies. During the year ended December 31, 2012, the parent made capital contributions of $17.6 million to a subsidiary.

Certain of our subsidiaries report their accounts in conformity with accounting practices prescribed or permitted by state insurance regulatory authorities, or statutory accounting. These subsidiaries are domiciled in various jurisdictions and prepare statutory financial statements in accordance with accounting practices prescribed or permitted by the respective jurisdictions' insurance regulators. Prescribed statutory accounting practices are set forth in a variety of publications of the National Association of Insurance Commissioners ("NAIC") as well as state laws, regulations and general administrative rules. The NAIC has developed a codified version of the statutory accounting principles, designed to foster more consistency among the states for accounting guidelines and reporting.

Statutory reporting varies in certain respects from GAAP. Typical differences of statutory reporting as compared to GAAP reporting are the reporting of fixed maturity securities at amortized cost, not recognizing certain assets including those that are non-admitted for statutory purposes and certain reporting classifications. Statutory-basis capital and surplus of our health plan subsidiaries was $143.8 million and $159.5 million at December 31, 2012 and 2011, respectively. Statutory-basis net income of our health plan subsidiaries was approximately $44 thousand, $4.3 million and $17.6 million for the years ended December 31, 2012, 2011 and 2010, respectively.

Our subsidiaries that are regulated by DMHC report their accounts in conformity with GAAP. GAAP equity of our DMHC regulated subsidiaries was $1.2 billion and $1.2 billion at December 31, 2012 and 2011, respectively. GAAP net income of our DMHC regulated subsidiaries was $122.1 million, $181.1 million and $146.9 million for the years ended December 31, 2012, 2011 and 2010, respectively.

We are a holding company and, therefore, our ability to pay dividends depends on distributions received from our subsidiaries, which are subject to regulatory capital requirements and other requirements of state law and regulation.

The maximum amount of dividends that can be paid by the regulated subsidiaries to us without prior approval of the state regulatory authorities is subject to restrictions relating to statutory surplus, statutory income and tangible net equity. See Note 6 for further discussion of restrictions on our ability to pay dividends to our stockholders that are contained in our revolving credit facility.
