- “In September 2024, the Company received €7,549,000 from the UK Plan as recovery of pension related costs previously incurred, which has been credited against the service cost in 2024, resulting in an associated income tax expense of €1,875,000.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
