Test of the method
The method was tested on the 497,331 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.
| 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 | 2.9% | 3.1% |
| 10 | 5.6% | 6.1% |
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 2,146 companies, not a prediction for TETHYS. 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.
