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 investment in unconsolidated subsidiaries, totaled $309.0 million at December 31, 2019 and $285.8 million at December 31, 2018.
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 VIE is limited to its direct ownership interest in the VIE. Except for the funding commitments disclosed in Note 9, ProAssurance has no arrangements with any of the VIEs to provide other financial support to or on behalf of the VIE. At December 31, 2019, ProAssurance’s maximum loss exposure relative to these investments was limited to the carrying value of ProAssurance’s investment in the VIE.
