Mats Langensjö, chairman of the review of Sweden’s AP Funds, has stepped down from his chief executive role at Brummer Life after less than 18 months in the role.

Industry veteran Langensjö, who began his career two decades ago at Mercer, left by “mutual agreement”, according to a statement issued by parent company Brummer & Partners.

Helena Palmgren, previously the life company’s vice-president, has been named interim chief executive following his departure.

Svante Elfving, chairman of the board at Brummer Life, thanked Langensjö for his time at the company and wished him well with future endeavors.

Langensjö joined Brummer in August 2012, after completing his time as chairman of the government-commissioned review of the Swedish AP Fund system.

During his six years at Mercer, he served as Nordic head of investment consulting and financial risk, leaving the consultancy in 1999 to work for Wassum Investment Consulting.

From there, he moved to London to join Goldman Sachs Asset Management as head of its Scandinavian institutional business.

He has since worked at Aon and Pioneer Investments, before being appointed chair of the AP Fund review – a review not received warmly by the funds themselves.
