Goldman Sachs said on Thursday that it would probably sell a majority stake in its European insurance unit in the next 12 months, adding to the assets slated to exit from the Wall Street firm as it adapts to stiffer capital rules.

The business, called Rothesay Life, had $9.66 billion in assets as of June, Goldman said in a regulatory filing. Goldman founded Rothesay in 2007 to focus on the UK pension market.
