How to read the index

The index says how a company is doing compared with similar companies the same year. It is not a grade on a fixed scale.

The 0–100 score

The score is a weighted average of percentiles for profitability, solidity, liquidity, growth and consistency. 50 means middle of the pack among the comparable companies.

“Better than X%”

Under every score and key figure it says what share of the peer group the company beats. 80% means the figure is better than at four in five.

Who it is compared with

Companies in the same sector, size tier and fiscal year. If the group is too small, the whole sector is used, and the page says so.

Data completeness

If a key figure is missing it is left out instead of counting as zero. Data completeness shows how much of the weight had data.

What the index is not

It is not a credit rating, not a recommendation and not a verdict on the company. A low score can have good explanations, such as investment or start-up.

Which year

Each figure is for one fiscal year, shown next to it. Accounts arrive through the year after the 31 July deadline.

Marks and flags

Flags such as “accounts missing” or “disputed” are information. They do not change the score.
