In fiscal 2021, work in process comprises approximately 21% (previous year: approximately 19%).

The significant increase in inventories was mainly attributable to external market conditions in fiscal 2021, in particular higher procurement and energy prices, as well as build-up in order to ensure supply reliability in fiscal 2022.

In fiscal 2021, impairment losses on inventories of €22 million (previous year: €24 million) and reversals of impairment losses of €5 million (previous year: €6 million) were recognized through profit or loss in cost of goods sold.
