Analysis and Interpretation of Profitability 3M COMPANY a. Compute net operating profit after tax (NOPAT) for 2018 . Assume that the combined federal and state statutory tax rate is 22%. b. Compute net operating assets (NOA) for 2018 and 2017. c. Compute and disaggregate 3M's RNOA into net operating profit margin (NOPM) and net operating asset turnover (NOAT) for 2018 . Demonstrate that RNOA = NOPM NOAT. RNOA may be different from first RNOA calculation due to rounding d. Compute net nonoperating obligations (NNO) for 2018 and 2017. Confirm the relation: NOA = NNO + Total equity e. Compute return on equity (ROE) for 2018. f. What is the nonoperating return component of ROE for 2018?
