In the latest revision of the Nordic Marine Insurance Plan, it was agreed to restrict the war risk cover to politically motivated interventions, with state interventions falling outside the war risk cover included in the marine insurance cover. The 2019 revision of the NMIP was approved by all parties and the document was published for use by insurance practitioners. The amendments in the 2019 version vary from small clarifications in clauses to more substantial re-writing of individual clauses.
