Global insurer Aviva has appointed Martin Muir as its group asset and liability management (ALM) director, effective 11 April 2011.

In this newly created role, Muir will have responsibility for the optimization and strategic asset allocation of the Aviva investment portfolio.

He will be based at Aviva’s headquarters in London and report into Tim Harris, Aviva’s deputy group chief financial officer and chief capital officer.

Muir will join Aviva from Goldman Sachs where he is currently a managing director in the securities division focusing on ALM & solvency solutions for insurance companies in Europe.

Prior to this, Muir spent more than 20 years at Watson Wyatt, where he was a main partner and leader of the UK life practice, specializing in providing advice to insurers on risk and value measurement and management.

Harris said Martin’s experience, talent and reputation will be a valuable addition to the team. This appointment is yet another clear demonstration of Aviva’s commitment to excellence in capital management.
