Liquidity insufficient (current ratio 0.72, compared with 0.81 in 2023, below 1; short-term debt: 42.7% and cash: 0% of total assets), and 67.8% 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 68, micro): better than 51% on solvency, 23% on liquidity, 21% on profitability and 30% on growth.

The bankruptcy probability was computed on 28-10-2026 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).

Historical observation

Of the 12,322 companies that looked in July 2024 the way this one looks now, 0.7% went bankrupt within 24 months and 90.3% are still going.

  • Micro
  • 20 years or older
  • solvency 30% or more
  • a small loss
0.7% went bankrupt
8.6% stopped otherwise
90.3% still going

A further 0.5% stopped, but we cannot tell whether within those 24 months.

For this company itself Checked computes a higher bankruptcy probability: 1.3% over twelve months. The score reads more about this company than the group's four characteristics; both figures are right about what they measure.

How reliable is this rule?

Tested on the year before, without using that year itself: the groups of July 2023 gave each of the 497,445 companies of July 2024 its group's bankruptcy share. Expected: 1.6%; actually bankrupt within 24 months: 1.7%.

The companies in ten equal groups, from lowest to highest expected share.
Group Expected Actual
1 0.2% 0.2%
2 0.3% 0.5%
3 0.5% 0.6%
4 0.7% 0.8%
5 0.9% 0.9%
6 1.3% 1.5%
7 1.6% 1.8%
8 1.8% 1.8%
9 3.0% 3.1%
10 5.6% 6.2%

The rule ranks well: a company that went bankrupt got a higher share than one that kept going in 74.5% of comparisons. The level follows the economy: in a year with more bankruptcies, the actual share is higher than the year before.

An observation about 12,322 comparable companies, not a prediction for this company. The sector does not count: the register keeps no sector for companies that stopped, so it would make the outcome look better than it was.
