Statutory Financial Information Disclosure [Text Block]	Note 21. Statutory Financial Information The Insurance Subsidiaries prepare their statutory financial statements in accordance with accounting principles prescribed or permitted by the various state insurance departments of domicile. Prescribed statutory accounting principles include state laws, regulations, and general administrative rules, as well as a variety of publications of the National Association of Insurance Commissioners ("NAIC"). Permitted statutory accounting principles encompass all accounting principles that are not prescribed; such principles differ from state to state, may differ from company to company within a state and may change in the future. The Insurance Subsidiaries do not utilize any permitted statutory accounting principles that materially affect the determination of statutory surplus, statutory net income, or risk-based capital ("RBC"). As of December 31, 2011, the various state insurance departments of domicile have adopted the March 2011 version of the NAIC Accounting Practices and Procedures manual in its entirety, as a component of prescribed or permitted practices. The combined statutory capital and surplus of the Insurance Subsidiaries was $1.1 billion (unaudited) in 2011 and in 2010. Excluding the recently-acquired MUSIC entity, the combined statutory net income of the Insurance Subsidiaries was $26.5 million (unaudited) in 2011, $86.9 million in 2010, and $69.8 million in 2009. The Insurance Subsidiaries are required to maintain certain minimum amounts of statutory surplus to satisfy their various state insurance departments of domicile. RBC requirements for property and casualty insurance companies are designed to assess capital adequacy and to raise the level of protection that statutory surplus provides for policyholders. Excluding MUSIC, the Insurance Subsidiaries combined total adjusted capital exceeded the authorized control level RBC, as defined by the NAIC, by 4.4:1 based on their 2011 unaudited statutory financial statements. MUSIC, based on its 2011 unaudited statutory financial statements, exceeded the authorized control level by 7.7:1.

- Definition

Discloses how the entity's reporting under GAAP as of the balance sheet date differs from the results based on prescribed and permitted accounting practices of the state or country of domicile in which a relevant statutory filing is made, or differences in results based on the National Association of Insurance Commissioners (NAIC) prescribed practices, or a combination thereof. Describes the accounting practices used and the related monetary effect on statutory surplus, net income and risk-based capital. If an insurance enterprise's risk-based capital would have triggered a regulatory event had it not used a permitted practice, that fact should be disclosed in the financial statements. Permitted statutory accounting practices include practices not prescribed but allowed by the domiciliary state insurance department regulatory authority.
