Peter Mwangi has been appointed group chief executive officer of Old Mutual Kenya, a subsidiary of London-headquartered international financial services firm, Old Mutual Group, as the company seeks to leverage on his experience for East African growth.

Mwangi, whose tenure as Chief Executive of Nairobi Securities Exchange (NSE) ends in November, will now take over the helm of leadership at the insurer’s Kenya subsidiary, from Rueben Java, who will move to southern Africa to oversee the Group’s Life business conducted principally by Old Mutual Life Assurance Company Zimbabwe Limited.

“We are excited to welcome Mr Mwangi to the Old Mutual Group,” said Tavaziva Madzinga, Old Mutual Africa Chief Operations Officer in a statement.

Madzinga, a former chief executive of Old Mutual Kenya himself, described Mwangi as leader with experience, who boasts a proven track record of “steering companies to deliver market–led solutions for customers.”

Mwangi was appointed NSE chief executive in 2008 on a three-year term but was subsequently extended by the same length. He is however set to step down on November 23, 2014. He exits with a legacy of having led the demutualization and imminent self-listing of the bourse.

Old Mutual Group, listed on Johannesburg Stock Exchange (JSE), Zimbabwe Stock Exchange (ZSE), as well as London Stock Exchange (LSE) is expected to continue its impressive growth in its Kenyan subsidiary under Mwangi, as it delivers its commitment to provide affordable insurance and banking solutions to millions of Kenyans. His appointment takes effect from October 1.
