4.4 The accountant of your business has recently been taken ill through overwork. In his absence, his assistant has prepared some calculations of the profitability of a project, which are to be discussed soon at the board meeting of your business. His workings, which are set out below, include some errors of principle. You can assume that the statement below includes no arithmetical errors. Year 1 Year 2 Year 3 Year 4 000 000 000 450 470 470 000 470 Year 5 Year 6 000 000 470 Sales revenue Less costs Materials Labour Overheads Depreciation Working capital Interest on working capital 180 Write-off of development costs Total costs Operating profit/(loss) 30 180 438 (180) 12 120 88 132 88 126 132 45 120 27 84 450 450 20 132 132 27 8| 94 47 120 120 8| 420 420 50 Total profit (loss) (28,000) Cost of equipment 600,000 Return on investment (4.7%) You ascertain the following additional information: The cost of equipment includes 100,000, being the carrying amount of an old machine. If it were not used for this project it would be scrapped with a zero net realisable value. New equipment costing 500,000 will be purchased on 31 December Year 0.

Overheads have been costed at 50 per cent of direct labour, which is the business's normal practice. An independent assessment has suggested that incremental overheads are likely to amount to 30,000 a year. The business's cost of capital is 12 per cent. Required: (a) Prepare a corrected statement of the incremental cash flows arising from the project. Where you have altered the assistant's figures you should attach a brief note explaining your alterations. (b) Calculate: (1) The project's payback period. (ii) The project's net present value as at 31 December Year 0. (c) Write a memo to the board advising on the acceptance or rejection of the project. Ignore taxation in your
