a. Compute the DuPont model component measures for profit margin, asset turnover, and financial leverage. Then, compute ROA.

Round profit margin and ROA to two decimal places (ex: 0.12345 = 12.35%) Round asset turnover and financial leverage to three decimal places.

Profit Margin: Answer (16.45% is correct)

Asset turnover: Answer

Financial leverage: Answer

ROA: Answer b. Compute ROE. Confirm that ROE equals ROE computed using the component measures from part a (ROE = PM x AT x FL). Round answer to two decimal places (ex: 0.12345 = 12.35%) Answer

c. Compute adjusted ROA (assume a statutory tax rate of 37% and pretax net interest expense of $123). Round answer to two decimal places (ex: 0.12345 = 12.35%) Answer
