The Du Pont Company pioneered a system of financial analysis that is widely used. Known as Du Pont analysis, it examines the interrelationships between elements in financial statements. Du Pont analysis depicts Return on Total Assets (ROTA) as the product of Net Profit Margin (NPM) and Total Assets Turnover Ratio (TATR). This decomposition helps understand how ROTA is influenced by NPM and TATR. The analysis can also be extended to Return on Equity (ROE) and evaluates how well a company manages assets, expenses, and debt.
