Catlin said the indicative price range for its forthcoming IPO was between 350 pence and 420 pence per common share.
This would value the group at between $1.0bn and $1.2bn following the flotation, said Catlin.
It said the offer price would be determined following a book-building process targeted at institutional investors in the UK and internationally.
The book-building period will end on 31 March 2004, said Catlin, with the offer price to be announced and conditional dealings beginning from 1 April 2004.
The listing is due to take place on 6 April 2004.
Catlin said the IPO would comprise $200m (£110m) of primary common shares issued by the company and up to $250m (£138m) of shares sold by existing shareholders.
The proceeds will be used to support the group’s underwriting and for general business purposes, it said.
