Part B (9 marks) Assume that Ridley is considering adding a new product line at one of its regional feed production facilities. The addition would increase the firm's capacity by almost 120% and improve production efficiency. The equipment required for the new production line will cost $3.9 million and requires $100,000 in installation costs. It will have an estimated life of 10 years, at which time it can be sold for an estimated after-tax scrap value of $300,000. Furthermore, at the end of five years, the production line will have to be refurbished at an estimated cost of $2 million. Management estimates that the new production line will add $850,000 per year in after-tax cash flow to the firm. The expected after-tax cash inflows from years 1 to 10 are provided in the following table: After-tax cash Year inflows $850,000 $850,000 $850,000 $850,000 -$1,150,000 $850,000 $850,000 $850,000 $850,000 10 $1, 150,000 Assume a discount rate of 9%.
