Adapting Beneish’s M-Score Across Accounting Standards

Article Quant Q&A · Author: McGin
Read the original

Summary

The document considers whether Beneish’s M-Score, developed using US company data, can be applied to UK firms reporting under IFRS. Its answer is that the model may still be usable, but financial statements should first be brought into a common accounting form. Applying the original inputs without checking accounting differences could make the resulting indicators less comparable.

The response identifies possible effects on the Receivables Index, Margin Index, and Asset Quality Index. It gives inventory accounting as an example: IFRS does not permit LIFO, unlike US GAAP, and this can affect cost of goods sold and reported inventory. The answer is brief and explicitly comes from someone who says they lack experience using the M-Score. It offers no empirical validation, proposed conversion procedure, or evidence that a standardized UK version preserves the model’s predictive performance. Researchers should therefore treat accounting comparability as a necessary consideration, not as proof that the model works equally well across markets.

Key ideas

  • The M-Score was developed from US company data, so applying it to UK firms raises accounting comparability questions.
  • The response recommends converting statements to a common accounting basis before calculating indicators.
  • Differences in inventory accounting, including the IFRS restriction on LIFO, can affect reported inputs.
  • The answer offers no empirical test of M-Score performance on UK companies.

# Can Beneish's model for detecting earnings manipulation be applied to companies in the UK?


# Can Beneish's model for detecting earnings manipulation be applied to companies in the UK?












As I understand it this model derived from data for US companies. Is it valid to apply the model as is to UK companies or does it require any modifications?

UK(IFRS) and the US(GAAP) use different accounting standards - off the top of my head you're likely to have differences at least in the Receivables Index, Margin Index, Asset Quality index due to inventory and costing differences. For example LIFO isn't permitted under IFRS, which is going to affect COGS and Inventory. It doesn't mean it's unusable, you'll just have to make sure to convert the statements into a common form. I don't have experience using the M-Score, and I didn't read much past the factors, but I would hope they outline the standard accounting assumptions for each factor.
