British engine maker Rolls-Royce slumped into a record annual net loss in 2016, ravaged by a Brexit-fueled collapse in the pound and a corruption fine.

The loss after tax of £4 billion, equivalent to $4.98 billion, contrasted with a slender profit of £84 million ($1.05 billion) in 2015, the company said in a results statement. Rolls took a vast £4.4 billion ($5.48 billion) hit from the drop in the value of the pound in the wake of Britain’s shock EU exit referendum, alongside a £671 million ($835.60 million) penalty to settle bribery allegations.
