Historical observation

Of the 17,811 companies that looked in July 2024 the way this one looks now, 0.3% went bankrupt within 24 months and 96.5% are still going.

  • Small
  • 10 to 20 years old
  • solvency 30% or more
  • a profit of 5% of the balance sheet or more
0.3% went bankrupt
3.2% stopped otherwise
96.5% still going

For this company itself Checked computes a bankruptcy probability of < 0.1% over twelve months; the group does not contradict it.

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 17,811 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.
