i got this info fron 2016 would it help ?

Grounded on a 3.2% after-tax cost of debt, and a 5.5% cost of equity, we were able to attain a 4.2% weighted average cost of debt (WACC) for NADEC, our target company. Correspondingly, we arrived at a 55.69% of debt-to-total capitalization and a 44.3% equity-to-capitalization ratio, which makes up the companys capital structure. In order to compute the companys cost of equity, we used the capital asset pricing model (CAPM). We collected the information from equity reports of analysts in the industry itself, where we were able to find out the market risk-premium of 1% and a risk-free rate of 3.8%. NADEC turned out to have a 6% cost of debt according to the companys financial statements, however, based on our calculations and findings

i want only solvency ratios and profitability ratios and efficiency ratios no need to calculate wacc just please show the equations for three years
