A QUESTION TO START WITH
Taller Norte is the fictional business in Guide 01. Compare working capital and investment with accounting profit, then work through the exercise.
Explore the worked solution ↗| Measure | Year 1 | Year 2 |
|---|---|---|
| Net profit | 100 | 120 |
| Operating cash flow | 110 | 90 |
| Capital spending | 60 | 100 |
| Simplified free cash flow | 50 | −10 |
