Quality of financial reporting: Balance sheet-based accrual ratio and cash flow-based accrual ratio.
If there is manipulation, you might as well look at cash flows too, like the case of Nestle right after checking the accrual ratios.
Explain why you’re using/not using a specific model. You probably don’t need to do both FCFE and FCFF, one would suffice.
Discuss the main assumptions you make and how you get there: Growth rate- why did you assume this? How do you calculate the required return on equity? What are your assumptions about your cost of debt and target capital structure? etc. Present your case and the valuation results clearly under each method.
