Assuming that;

The ratio of variable costs to sales, working capital to sales, and capital expenditure to sales are the same as year 0 (2016);

The Debt-to-Equity (D/E) ratio is the same as year 0 (2016) and will remain constant;

Fixed costs and depreciation from year 1 (2017) onwards are the same as the average over the last 4 years;

Cost of debt is 7.5%, the risk free rate is 3% and expected effective tax rate is 26%.

With these assumptions, and this data https://drive.google.com/file/d/0BzfwwFlPWBEFTUhZNndZM0s1VFE/view?usp=sharing

How would I calculate the cost of equity of 'Facebook' using CAPM?

Whoever answers gets instant thumbs up :)
