The Statbank tables REGN10, REGN20, REGN30 and REGN50 are all based on the accounting statistics for private non-agricultural industries at the level of the economic unit. Differences may occur in some accounting items across the four tables due to confidentiality adjustments (discretionary suppression). These adjustments also affect the totals in the tables, which is particularly evident in REGN10, as it is broken down by a more detailed industry classification. This means that the aggregated values of accounting items are generally lower in REGN10 than in the other tables.
