(a) Compute net operating profit after tax (NOPAT) for 2006. Assume that the combined federal and statutory rate is: 38.3%. (Round your answer to the nearest whole number.) HINT: For Sales use "Total revenues" for your computations, when applicable. (a) Compute net operating profit after tax (NOPAT) for 2006. Assume that the combined federal and statutory rate is: 38.3%. (Round your answer to the nearest whole number.) 2006 NOPAT = $ 2694 million (b) Compute net operating assets (NOA) for 2006 and 2005. 2006 NOA = $ 22429 million 2005 NOA = $ 20322 million (c) Compute Target's RNOA, net operating profit margin (NOPM) and net operating asset turnover (NOAT) for 2006. (Do not round until final answer. Round two decimal places. Do not use NOPM x NOAT to calculate RNOA.) 2006 RNOA = 12.6 % 2006 NOPM = 0 X % 2006 NOAT = 2.28 x (d) Compute net nonoperating obligations (NNO) for 2006 and 2005. 2006 NNO = $ 0 X million 2005 NNO = $ 7293 million (e) Compute return on equity (ROE) for 2006.
