How it is calculated
Output not produced = actual rate × stopped hours. Economic exposure = output not produced × contribution per tonne + additional labour + other direct costs.
What the estimate means
- Use contribution after avoidable variable costs, not the selling price per tonne.
- Enter only additional intervention costs to avoid counting normal labour twice.
- This is a scenario estimate, not an accounting loss. Stock buffers, catch-up production and demand may reduce the impact.
