The facts

Through corporate acquisitions and asset transfers, BAT Industries plc (“BAT”) (a Claimant in the proceedings) became liable to contribute to the clean-up of the sediment of the Lower Fox River in Wisconsin, U.S.A. Arjo Wiggins Appleton Limited (“AWA”), a wholly owned subsidiary of Sequana SA (“Sequana”) (a Defendant in proceedings), became liable to indemnify BAT for part of any monies paid out. Provision was duly made in AWA’s accounts to reflect a best estimate of the value of such liability.
