The office will offer film underwriting to European production companies.
Ian Mercer, an insurance executive with 20 years of experience in the UK and US, will head the new office, located on Leadenhall Street.
Fireman's Fund will work with one of its parent company subsidiaries, Allianz Insurance in the UK, to provide comprehensive services to production companies and vendors.
'This is the first step in broadening our unmatched experience and expertise in film underwriting, backed by the power of our parent Allianz, a global insurance leader,' said Joe Finnegan, VP of Fireman's Fund Entertainment. 'Over the years, we have been underwriting productions that are filmed in Europe and other global regions - but now we'll be able to offer an increased ease of doing business by providing local coverage we weren't able to offer before, local underwriting knowledge and eliminating time differences.'
