The family’s investment vehicle in the grand duchy, Precision Capital, has held 90% of the bank’s shares since 2012.
Precision is holding preliminary talks with potential buyers, according to Bloomberg. The sale could net around $1.5bn, the news service said on Thursday.
Representatives of Precision, Bil and Luxembourg’s finance ministry declined to comment, Bloomberg reported.
Bil is the oldest private bank in Luxembourg. Its net income dropped from €108m to €45m between the first halves of 2015 and 2016.
