How the Beneish M-score works
M = −4.84 + 0.920 × DSRI + 0.528 × GMI + 0.404 × AQI + 0.892 × SGI + 0.115 × DEPI − 0.172 × SGAI + 4.679 × TATA − 0.327 × LVGI (Beneish, 1999): eight changes in the accounts from one fiscal year to the next, which the model weighs for the pattern seen in companies that later restated their earnings. Higher is worse.
| below −2.22 | Low — no pattern the model associates with manipulation |
|---|---|
| −2.22 to −1.78 | Elevated |
| above −1.78 | Flagged by the model |
−1.78 is the cut-off usually quoted from the paper, −2.22 a common conservative one. A statistical screen, not a finding of wrongdoing.
When asset quality, depreciation or SG&A cannot be worked out, that index is set to 1, as Beneish did, and the breakdown says so; with all three missing there is no score. Depreciation includes amortisation, and asset quality leaves out securities. Not worked out for banks, insurers and REITs.
