SurvivalSafe zone

Financially healthy, low distress risk Altman Z-score, a bankruptcy-risk model from five balance-sheet ratios.

Honest booksGrey zone

Some accounting flags, worth a closer look Beneish M-score, a forensic model that detects earnings-manipulation patterns (receivables outrunning sales, margins slipping, accrual-heavy profit).

Quality6 / 9
