English Court decides Covid-19 is a “catastrophe”

The English Court has, for the first time, considered the meaning of a “catastrophe”, as well as how Hours Clauses work in the context of non-damage business interruption losses claimed under two Property Catastrophe Excess of Loss Reinsurance Treaties.  While the Covid-19 pandemic may feel like a distant memory to some, disputes about the recovery of Covid-19 losses continue to trouble many reinsureds and reinsurers.  The two key issues considered by the Commercial Court in determining appeals from arbitration awards made in Unipol Re v Covéa and Markel v Gen Re may bring welcome, and valuable, guidance to those in the reinsurance industry debating these terms. Those underwriting or purchasing “catastrophe” covers may also want to carefully consider this judgment and whether the Court’s approach to the meaning of that word aligns with their coverage expectations.

Corbin & King: Denial of Access clause and Composite policy cover for COVID-19

The Commercial Court has found in Corbin & King Ltd v Axa Insurance UK Plc that a Non-Damage Denial of Access (“NDDA”) clause responds to COVID-19 business interruption losses.  Further, that where the policy provides cover by reference to the Insureds’ “business” where access to its “premises” was restricted, that the insured would be entitled to claim the sub-limit of cover in respect of each premises, for each lockdown or restriction.  This decision, if upheld by appellate courts, could materially increase some insurers’ exposure to COVID-19 business interruption losses if they have underwritten comparable NDDA covers.
