"If an entity is in an Annex I sector and meets the 'Large' size threshold, it is Essential. Otherwise, its status (Important or Essential) is determined by its specific sector, its role in the market, or its designation by national authorities."
To be "Large," you must meet the employee threshold AND at least one of the financial thresholds.
1. Staff Headcount: 250 employees (Annual Work Units)
AND
2. Financials (Either):
o Annual Turnover: $>$ €50 million
o Annual Balance Sheet Total: $>$ €43 million
"Essential" entities in High Criticality sectors face proactive supervision (checks before anything goes wrong), while "Important" entities in other sectors typically face reactive supervision (investigations after an incident).
