LONDON--South African financial services firm Old Mutual PLC (OML.LN) said Friday it is selling Skandia Leben AG in Switzerland to Life Invest Holding AG, a company owned by the Mutschler Group and Hannover Re, for an undisclosed sum.

At Dec. 31, 2014, Skandia Leben had funds under management of 1.3 billion Swiss francs ($1.38 billion).

The transaction is expected to take six months to complete, Old Mutual said, adding that the deal continues Old Mutual Wealth's commitment to simplify its operations.
