Credit of up to €25,000 on 30-day terms is acceptable

Liquidity ample (current ratio 2.26, compared with 1.91 in 2024, above the usual 1.5; short-term debt: 43.3% and cash: 0.1% of total assets), and 43.3% of the assets are financed with debt and provisions.

How it is calculated

The band follows from the bankruptcy probability, on a scale where 10 more points roughly halve it:

75-100	Excellent	under 0.55%
60-74	Healthy	0.55% to 1.5%
45-59	Fair	1.5% to 4.2%
25-44	Weak	4.2% to 15.0%
0-24	Critical	over 15.0%

Where the company stands within its band depends half on the bankruptcy probability and half on how it does against its sector peers (NACE 43, micro): better than 62% on solvency, 18% on liquidity, 14% on profitability and 33% on growth.

The bankruptcy probability was computed on 25-10-2026 by the bankruptcy model of 2 October 2026, which learns from Belgian bankruptcies and reads the registers, the annual accounts and the Belgian Official Gazette.

Some facts cap the score, however low the probability. Negative or zero equity, a heavy loss, a special status in the KBO, one missing filing or accounts filed more than 90 days late hold it at Fair at most (59); two missing filings, at Weak (44). An ongoing judicial reorganisation or the company's end (bankruptcy, dissolution, liquidation) holds it at Critical at most (24).
