Goodwill and Intangible Assets Disclosure [Abstract]    
Facts and circumstances leading to impairment During the second quarter of 2012, the Company's subsidiary, Celtic Insurance Company, experienced a high level of medical costs for individual health policies, especially for recently issued policies related to members converted from another insurer during the first quarter of 2012. Additionally, in June 2012, the U.S. Supreme Court upheld the constitutionality of the Patient Protection and Affordable Care Act which limits the profitability of the individual health insurance business because of minimum medical loss ratios, guaranteed issue policies, and increased competition in the exchange market.
