St Paul's president of international insurance operations Mark Pabst is to retire after 12 years with the company.

St Paul chairman and chief executive, Douglas Leatherdale, announced Pabst's retirement on Monday and the selection of his replacements Kent Urness and Michael Schell.

Urness, senior vice-president and global specialist practice leader, will assume responsibility for St Paul's primary insurance operations outside the US. Schell, president and chief operating officer for global reinsurance, will take over the Lloyd's operations. The Lloyd's business includes 12 syndicates under management, which makes St Paul's the fourth largest managing agent at Lloyd's.

Leatherdale also announced several organisational changes related to Pabst's retirement. The Global Healthcare organisation, formerly reporting to Urness, will report to senior vice-president and global specialist practice leader Mike Miller.

Miller will continue to head the financial and professional services, public sector and excess and surplus lines organisations.

Schell will continue to run St Paul's global reinsurance through the 11 offices of St Paul Re.
