To be clear, there is nothing wrong with adjusting provisions when warranty reserves are not fully needed or a restructuring cost estimate was overly conservative.

While Heidelberg's service segment is consistently profitable on an operating profit basis (albeit with relatively large quarterly swings) and the financial services segment seems to be doing really well (Euro 5 million operating profit on Euro 3 million sales in the fourth quarter), the equipment segment has not been profitable for several years.
As the chart below illustrates, HD's equipment segment was profitable only in the last quarter of the two last fiscal years, always on peak sales. (Note, for clarity, operating profit in red is tied to the right y-scale, while sales, orders and backlog use the left scale.)
