The corporate shake-up necessary for Bermuda-based PartnerRe Ltd. to embrace fully the reinsurance operations of Winterthur Group is finally complete.

PartnerRe's acquisition of the New York-based corporation with operations in Dallas and reinsurance business in Switzerland was finalised in December last year.

But the multi-line reinsurer has taken until now to finish rejigging its organisational structure to squeeze in Winterthur.

And, predictably, with the reorganisation has come a reshuffle of the company's management team.

The company released a statement announcing its new "fully integrated structure''.

One team for each geographic market and one for each business line have been identified to manage the Group's client and underwriting relationships.

"These changes, effective April 1, will provide optimal access to the company's services and expertise for its clients around the world,'' it said.

The Switzerland-based former head of Winterthur Re, Bruno Meyenhofer, was appointed Chief Operating Officer of PartnerRe's Global Reinsurance Operations to oversee all reinsurance departments.

PartnerRe's president and CEO Herbert Haag said after the acquisition of Winterthur Re the company had moved "quickly and smoothly'' to integrate operations in Paris, Switzerland and New York.

"We have created a modern, team-oriented organisation capable of supporting our long-term development,'' he said.

"With the appointment of Bruno Meyenhofer to head our reinsurance operations, we have added depth to our management structure. In the short time since Bruno joined our Group, he has demonstrated vision, leadership and the highest level of expertise in pursuing the company's goals.

"His strategic and managerial strengths coupled with his vast experience in the reinsurance business, will assist me greatly in successfully leading PartnerRe forward.'' In a separate announcement yesterday it was revealed that PartnerRe Chief Financial Officer Karen O'Connor Rubsam had resigned effective May 1 to "pursue personal interests''.

Mr. Haag said the company was currently evaluating a number of candidates to replace Ms O'Connor Rubsam who had been in the position for less than a year.

PartnerRe US president and CEO Scott Moore -- who served as CFO from the company's inception until July last year -- was to oversee the CFO role until a replacement was found.

"We greatly appreciate the contributions Karen has made to PartnerRe during her short term as CFO and we regret her decision to leave the company,'' Mr.

Haag said. "We wish her well in her future endeavours.'' Herbert Haag
