Dupont Model
The DuPont Model is a methodology that computes Return on Equity by component parts.
Business owners and shareholders are very interested in their level of return.
A method of consulting with business owners and shareholders on ways to boost Return on Equity would be very valuable to the CPA.
The DuPont Model was first used by the DuPont Corporation in the 1920’s. 
ROE = Net Profit Margin x Asset Turnover x Equity Multiplier
or ROE = (Net Income / Sales) x (Sales / Total Assets) x (Total Assets / Equity).
