About the figures

Figures are the latest annual accounts filed with the Register of Company Accounts, matched to the activity code the company carries in the Central Coordinating Register. A company lands in an industry on the strength of that registered code, not an assessment of what it actually does.

The operating-margin list and the median use only the 3 103 companies with at least 5 employees and over 5 mill. kr in revenue, so a small company with erratic figures cannot top the list.

7 companies are held out because their operating margin exceeds 75% – far above the norm for this industry. That is almost always a wrong activity code or fair-value gains booked as operating revenue, not trading.
