At a glance

  1. AM Best frames the extension around terrorism and political violence, and CityScape's portfolio-level design indicates modeling across a book of insured locations rather than one risk at a time.
  2. For brokers and cedents placing terrorism and political violence cover, the practical effect is continuity: an existing arrangement stays in force.
  3. The AM Best News report does not give the extension's length, value or any widening of the perils covered.
