Profit at Peter Anker's private holding company was buoyed last year after it cashed in shares in UK-listed Clarksons.
Anker, former head of Norwegian shipbroker RS Platou, became a shareholder in Clarksons via his investment company Langebru after the two shipbroking giants merged in 2015.
As TradeWinds has reported, Anker sold 107,477 Clarksons shares in September last year for a total of £2.9m
