Altman Z''
A four-ratio balance-sheet stress score (Z'' book-value variant, Altman 1983) that sorts companies into distress, grey and safe zones.
Formula
6.56×(working capital ÷ assets) + 3.26×(retained earnings ÷ assets) + 6.72×(EBIT ÷ assets) + 1.05×(book equity ÷ liabilities)
Served as: annual · derived. Annual and quarterly observations are never mixed unlabeled.
Where the inputs come from
- Computed server-side from filed balance-sheet and income-statement concepts
Listed highest priority first. Every served figure carries its filing, fiscal period and accession; open any value on the financials page to see them.
How to compare it honestly
Read the zone, not the decimal; the variant was calibrated on manufacturers and emerging-market credits.
When it is not served
Not meaningful for banks and insurers, whose balance sheets the model was never calibrated for; sector misfit is labeled.
Missing data is missing evidence: it is never shown as zero and never treated as a conclusion.
What it cannot tell you
A historical statistical screen, not a default prediction; inputs are book values with accounting lag.
Questions worth asking next
- Which of the four components moved the score?
- Does the debt maturity schedule corroborate or soften the zone reading?
Research prompts, not recommendations.
