TMK Ltd is considering buying a new machine which would have a useful economic life of five years, a cost of Tshs$.100$ million and scrap value of Tshs$.5$ million. The machine would produce $50,000$ units per annum of a new product with an estimated selling price of Tshs$.3000$ per unit. Direct costs would Tshs$.1750$ per unit and annual fixed costs, including depreciation calculated on a straight line basis, would be Tshs$.40$ million per annum. In years $1$ and $2,$special sales promotion expenditure, not included in the above costs, would be incurred, amounting to Tshs$.10$ million and Tshs$.15$ million respectively. As a consequence of this particular project, investment by the company in debtors and stocks would increase, during year $1,$ by Tshs$.15$ million and Tshs$.20$million respectively, and creditors would also increase by Tshs$.10$ million. At the end of the machine's life, debtors, stocks and creditors would revert to their previous levels. Evaluate the project using the NPV method of investment appraisal, assuming the company's cost of capital is $10\%.$
