Maybe one time write offs? Hard to imagine any other way you could lose 160 million on 180 million in sales.
If you have a dollar in sales, and $160 million in fixed and (somewhat) variable overhead expenses, like salaries, pension expenses, office rent, depreciation, etc., etc., it's pretty easy to lose any amount of money, having nothing to do with your sales volume.
