(a) Compute net operating profit after tax (NOPAT) for 2010. Assume that the combined federal and statutory rate is: 37.0% (Round your answer to the nearest whole number.)

2010 NOPAT =

(b) Compute net operating assets (NOA) for 2010 and 2009. Treat noncurrent Investments as a nonoperating item.

2010 NOA =

2009 NOA =

(c) Compute 3M's RNOA, net operating profit margin (NOPM) and net operating asset turnover (NOAT) for 2010. (Round your answers to two decimal places. Do not round until your final answer. Do not use NOPM x NOAT to calculate RNOA.)

2010 RNOA =

2010 NOPM =2010 NOAT =

(d) Compute net nonoperating obligations (NNO) for 2010 and 2009.

2010 NNO =

2009 NNO =

(e) Compute return on equity (ROE) for 2010. (Round your answers to two decimal places. Do not round until your final answer.)

2010 ROE =

(f) What is the nonoperating return component of ROE for 2010? (Round your answers to two decimal places.)

2010 nonoperating return =

(g) Which of the following statements reflects the best inference we can draw from the difference between 3M's ROE and RNOA?

ROE > RNOA implies that 3M has taken on too much financial leverage.ROE > RNOA implies that 3M is able to borrow money to fund operating assets that yield a return greater than its cost of debt.ROE > RNOA implies that 3M's equity has grown faster than its NOA.ROE > RNOA implies that 3M has increased its financial leverage during the period.
