Decision tree/real options analysis

Price of commodity now is $55 per ton

You produce 80,000 tons per year

$5,000,000 per year to operating costs

Can operate for 88 years before closing down

Shutting down requires you to spend $5,000,000 or transfer mine ownership without cost and gain $2,000,000 in year 1 only

Equal probability of price going up 25%, staying same price same price or going down 30% every year for next 3 years. After 3 years price remains constant for remaining life.

Cost of capital is 15%

Create a decision tree to summarise dilemma then calculate the NPV of continuing to operate the mine taking into account the probability of each outcome, the abandonment option and the cost of capital.
