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

The sector band is the middle half of the companies in Real estate activities (NACE 68). 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 and return on assets (ROA).

Companies with the same profile, two years later

Historical observation

In July 2024, 4,107 companies had the same profile as SOLID'AIR has now. Two years later, 1.0% had gone bankrupt and 98.0% were still going.

  • Small
  • 10 to 20 years old
  • solvency 10 to 30%
  • a profit under 5% of the balance sheet
1.0% went bankrupt
0.9% stopped otherwise
98.0% was still going

Another 0.2% stopped without a precise date, possibly only after those two years.

The bankruptcy probability of SOLID'AIR itself is higher: 1.2% within 12 months. It rests on far more data about SOLID'AIR than the profile alone.

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 4,107 companies, not a prediction for SOLID'AIR. 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.
