The supervisory board at insurance group Delta Lloyd has clawed back some of senior executives’ 2012 bonuses because of the insider trading scandal, the Financieele Dagblad says on Monday.

The supervisory board has used its ‘discretionary powers’ to reduce 2014’s bonus to make up for the wrongful payment in 2012, according to Delta Lloyd’s annual report.

Delta Lloyd is embroiled in a dispute with the Dutch central bank about the issue. It emerged at the beginning of this year that Delta Lloyd was fined a record €22.8m in 2014 for acting on confidential information that interest rates were being adapted.

Both the central bank and the financial sector regulator AFM say Delta Lloyd was involved in insider trading, which the company disputes. The issue is currently the centre of a court case.

The claw-back saw former chairman Niek Hoek’s 2014 bonus reduced to €45,200 last year, compared with €164,000 in 2013. Emiel Roozen, the financial chief forced out by the central bank, saw his bonus cut by 66% to €33,400.

The supervisory board says its own investigation into events shows ‘very little’ difference with those of the central bank.
