Every company registered today counts under its main activities in the KBO. Establishment units do not count. Staff counts once, under the employer's first main activity, from its latest accounts and only where it fits the staff costs. The count follows the NACE 2003 classification, the version in which code 4522 exists.

Division 45 has another description in the NACE 2003 classification than in the current one. The key figures and the median bankruptcy probability per division are counted in the current classification, so they do not apply to this code.

The bankruptcies over five years count only companies still registered today, because the activity of a company that left the register is not kept. So they are fewer than the bankruptcies of those years, and the figure is not a probability for the future. Over twelve months the count is nearly complete, because a bankrupt company stays registered while its bankruptcy runs. A company with more than one main activity counts in each of those sectors.

The comparison with Belgium as a whole and with the other NACE divisions rests on an overview of every division, counted again each night. Each division is counted in the version of the NACE classification in which it exists. A standing such as "more than in 80%" compares with the other divisions that have the figure. A division's bankruptcy probability is the median over its companies with a score. Belgium here counts the 1,276,474 companies with a main activity, because only those belong to a division. The other 699,509 registrations publish no activity.
