Calculation
The band follows from the bankruptcy probability. 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 41, micro). It does better than 35% of them on solvency, 20% on liquidity, 32% on profitability and 25% on growth.
The bankruptcy probability was computed on 09-11-2026 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.
The probability rests on the annual accounts with balance sheet date 31-12-2025.
Of the companies with a bankruptcy probability in the elevated class on 30-06-2025, 6.3% went bankrupt within twelve months.
Some facts cap the score, however low the probability. With negative or zero equity, a heavy loss, a special status in the KBO, one missing filing or accounts filed more than 90 days late, the score is Fair at most (59). With two missing filings, it is Weak at most (44). During a judicial reorganisation or at the company's end (bankruptcy, dissolution, liquidation), it is Critical at most (24).
Comparable companies, two years later
In July 2024, 1,271 companies had the same profile as Sergey Services has now. Each dot stands for 4 companies, two years later.
93.4%
were still trading
2.0%
stopped another way
4.1%
went bankrupt
Another 0.5% stopped without a precise date, possibly only after those two years.
The bankruptcy probability of Sergey Services itself is higher: 7.2% within 12 months. It rests on far more data about Sergey Services than the profile alone.
Test of the method
The method was tested on the 497,447 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 | 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 1,271 companies, not a prediction for Sergey Services. 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.
Credit verdict
Credit of up to €1,500 on 30-day terms, only on tighter conditions: elevated estimated bankruptcy probability calls for adjusted credit terms
Liquidity is tight, with a current ratio of 1.21 (1.48 in 2024), below the usual 1.5. Short-term debt is 53.4% and cash 1% of total assets. 72% of the assets are financed with debt and provisions.

The financial year that closed on 31-12-2025 was due by 31-07-2026 and was filed on 14-10-2026, 75 days later. Nearly half (47%) of Belgian companies file late; of those that file 1 to 90 days late, 2.0% are now bankrupt, dissolved or in another special legal status, against 1.66% of all filers. A delay like this does not count in the score.
