The bank said Kairos' assets under management grew to 11 billion euros in 2017, up from approximately 4 billion euros in 2013 when Julius Baer took a 19.9 percent stake in Kairos that it increased to 80 percent in 2016.

The bank said Kairos's executive management would stay in place with current Chief Executive Paolo Basilico also assuming the role of chairman.
