Please show steps on how to solve the below:

1.Calculate NOPAT for the past two years using a statutory tax rate of 22.4% for fiscal 2018 and 25% for fiscal 2019 (y.e. 2/29/20) for the tax shield calculation. Calculate NOA for the past three years. (You will need to gather information from one additional 10-K report to calculate average operating assets and equity for question 2)

2.Calculate RNOA and ROE for the most recent two years. (As above, you will need to gather information from one additional 10-K report to calculate average operating assets and equity.) Expand the RNOA into NOPM and Asset Turnover measures.Expand ROE into Profit Margin, Asset Turnover and Leverage.
