Turnover is what the company sold, the result is what was left of it. A loss stands below the zero line.

Use the arrow keys on the chart for the figures per year.

The sector band is the middle half of the companies in Specialised construction activities (NACE 43). A quarter of them sit below it, a quarter above. Each year counts only accounts in the same format, and only where there are at least 30. The dashed line is the median. There is a sector band for net result, equity, total assets, working capital, solvency, current ratio, return on assets (ROA) and staff (FTE).

Companies with the same profile, two years later

Historical observation

In July 2024, 4,685 companies had the same profile as INTERDOOR has now. Two years later, 1.1% had gone bankrupt and 96.9% were still going.

  • Small
  • 20 years or older
  • solvency 10 to 30%
  • a profit under 5% of the balance sheet
1.1% went bankrupt
1.9% stopped otherwise
96.9% was still going

That fits the bankruptcy probability of INTERDOOR itself: 0.2% within 12 months.

Test of the method

The method was tested on the 497,445 companies of July 2024. Each company was given the bankruptcy share of the same profile a year earlier, in July 2023. The expectation was that 1.6% would go bankrupt within 24 months. In fact 1.7% went bankrupt.

The companies in ten equal groups, from the lowest to the 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%

A company that went bankrupt had a higher expected share than one that kept going in 74.5% of comparisons. The level depends on the economy. In a year with more bankruptcies than the year before, the actual share is higher than the expected one.

This is an observation about 4,685 companies, not a prediction for INTERDOOR. The sector does not count, because the KBO no longer lists a sector for a company that has stopped. By sector, mostly the survivors would count, which would paint too rosy a picture.
