well in test marketing trials conducted recently by the company’s research and development division. The following information relating to this investment proposal has now been prepared.

Initial investment $2 million

Selling price (current price terms) $20 per unit

Expected selling price inflation 3% per year

Variable operating costs (current price terms) $8 per unit

Fixed operating costs (current price terms) $170,000 per year

Expected operating cost inflation 4% per year

The research and development division has prepared the following demand forecast as a result of its test marketing trials. The forecast reflects expected technological change and its effect on the anticipated life-cycle of Product W33.

It is expected that all units of Product W33 produced will be sold, in line with the company’s policy of keeping no inventory of finished goods. No terminal value or machinery scrap value is expected at the end of four years, when production of Product W33 is planned to end. For investment appraisal purposes, PV Co uses a nominal (money) discount rate of 10% per year and a target return on capital employed of 30% per year. Ignore taxation.

Required:

(a) Identify and explain the key stages in the capital investment decision-making process, and the role of

investment appraisal in this process. (7 marks)

(b) Calculate the following values for the investment proposal:

(i) net present value;

(ii) internal rate of return;

(iii) return on capital employed (accounting rate of return) based on average investment; and

(iv) discounted payback period. (13 marks)

(c) Discuss your findings in each section of (b) above and advise whether the investment proposal is financially acceptable. (5 marks)

o take on part-time jobs. To make finding those jobs easier, the placement services put together a listing of what is available locally. For some students these part-time jobs could lead to full-time work after graduation as they may offer experience in their own fields, be that finance, marketing, or even management. For example, National Savings Bank offers work on a half time basis: that's twenty hours a week. Retail stores and restaurants have positions requiring fewer hours, even less time for those providing child care. We have a number of families registered with us who are looking for babysitters for as few as four hours a week. For students who prefer outdoor work, there are seasonal positions right on campus working with the gardening and landscaping teams. Those often require the most time and are. the least flexible in terms of scheduling. To see a complete list of these and other available jobs, including the salary offered and the hours required, stop by our office. In addition, our counselors will give you hints about successful interviewing.

How many hours does National Saving Bank offer the part-timer to do per week？

A．4 hours.

B．20 hours.
