James Montier (former Soc Gen global equity strategist) aimed to create a simple scoring system that would highlight companies that may be 'cooking the books'. The C-Score was the result. It measures six inputs including the divergence between net income and cash-flow, increasing days sales outstanding, increasing days sales of inventory, increasing current assets to revenues, declining depreciation relative to PPE and high total asset growth. Montier found that companies with high C-Scores under performed the market by 8% per annum, generating a mere 1.8% return between 1993 and 2007. He recommended using it in tandem with a high valuation measure. A C Score = 5 used in tandem with a Price/Sales Ratio > 2 generated a negative absolute return of 4% p.a. in the US.
