Swiss Re Ltd (SWX:SREN) is pressing ahead with plans to float ReAssure Group Limited in London. ReAssure intends to list at least a 25% stake, it said. Under the flotation plans, Swiss Re would cut its stake in ReAssure to below 50% from 75% now. MS&AD Insurance Group Holdings intends to keep its holding at 25% after the Initial Public Offering (IPO), ReAssure Chief Executive Officer Mark Hodges told a media call. ReAssure’s publication of the registration document for the IPO will be the first step towards a listing, Swiss Re said. The document is due to be published later. The final timing of the IPO has not been decided, Hodges said. Morgan Stanley, Credit Suisse, and UBS are the joint global coordinators, while BNP Paribas and HSBC will act as joint book runners in the flotation.
