Method

The grade is computed by fixed rules. Each area gets 0 to 100 points from published thresholds, and the points are weighted. A missing area is left out and its weight shared by the rest. A is 80 points or more, B 65, C 50, D 35, and E below that.

Solidity (30 %): equity ratio. 40% or more gives 100 points, 30% gives 85, 20% gives 65, 10% gives 45, 0% gives 25, and negative equity gives 0.
Liquidity (20 %): current ratio. 2.0 or more gives 100 points, 1.5 gives 85, 1.2 gives 65, 1.0 gives 45, and below 1.0 gives 15.
Profitability (20 %): average of operating margin and profit margin. 10% or more gives 100 points, 5% gives 80, 0% gives 55, and a negative margin gives 15.
Size and capacity (10 %): the largest contract in Doffin against revenue. Below 10% gives 100 points, below 30% gives 70, below 60% gives 40, otherwise 15. Without contracts, revenue counts: NOK 50m gives 85, NOK 10m gives 70, NOK 1m gives 50.
Experience from public contracts (20 %): contracts won in Doffin in the last five years. 10 or more give 100 points, 3 give 85, 1 gives 65, and none gives 40. Contracts from at least three different buyers add 10 points.

Hard signals override: bankruptcy or winding-up gives E, negative equity at most D, and missing annual accounts at most C.

The written assessment is written by artificial intelligence from the same figures and labelled «AI-generated». Every number in it is checked against the database before it is shown; if the check fails, text put together from fixed rules is shown. AI does not set the grade.

The assessment is an indication based on public data: the latest annual accounts from the Brønnøysund Register Centre and contracts in Doffin. It is not a credit rating and not advice to choose or reject a supplier. The page is not indexed by search engines.
