Chubb has appointed Jason Keen as Head of Property and Casualty for Asia-Pacific under a shake-up of senior positions.

He takes over from Paul McNamee, who was last month named Regional President Asia-Pacific.

Mr Keen is currently Head of Property in the region, a position he held with Ace before it completed its acquisition of Chubb in January.

“Jason is a proven leader with a strong sense of vision for his business and an unwavering focus on execution,” Mr McNamee said.

“We are delighted to once again promote talent from within our ranks to such a critical position, in a region that continues to offer so much potential.”

Mr Keen also has experience as an underwriter at Lloyd’s in London and North America.

Zurich-based Ace this year acquired US rival Chubb and took its name, creating a “global property and casualty powerhouse”.
