Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities ProAssurance holds passive interests in a number of entities that are considered to be VIEs under GAAP guidance. ProAssurance's VIE interests principally consist of interests in LPs/LLCs formed for the purpose of achieving diversified equity and debt returns. ProAssurance's VIE interests carried as a part of Other investments totaled $26.9 million at both March 31, 2017 and December 31, 2016. ProAssurance's VIE interests carried as a part of Investment in unconsolidated subsidiaries totaled $270.7 million at March 31, 2017 and $282.3 million at December 31, 2016. ProAssurance does not have power over the activities that most significantly impact the economic performance of these VIEs and thus is not the primary beneficiary. Therefore, ProAssurance has not consolidated these VIEs. ProAssurance’s involvement with each entity is limited to its direct ownership interest in the entity. Except as disclosed in Note 7 of the Notes to Condensed Consolidated Financial Statements, ProAssurance has no arrangements with any of the entities to provide other financial support to or on behalf of the entity. At March 31, 2017, ProAssurance’s maximum loss exposure relative to these investments was limited to the carrying value of ProAssurance’s investment in the VIE.
