Advanced-level exercises 14.6 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 dis- cussed soon at the board meeting of your business. His workings, which are set out below, include some errors of principle. You can assume that there are no arithmetical errors. 0 1 2 000 000 000 450 470 3 4 000 000 470 470 5 000 470 132 132 94 94 126 90 45 120 132 94 47 132 94 47 120 Year Sales revenue Less Costs Materials Labour Overheads Depreciation Working capital Interest on working capital Write-off of development costs Total costs Operating profit/(loss) 47 47 120 120 120 180 27 27 27 27 27 30 438 12 30 450 30 450 180 420 420 (180 20 20 50 50 Total profit (loss) (E28,000) Cost of equipment 2600,000 - Return on investment (4.7%) You ascertain the following additional information: 1 The cost of equipment includes 100,000, being the carrying value 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. You should assume that all other cash flows occur at the end of the year to which they relate. 2 The development costs of 90,000 have already been spent. 3 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. 4 The business's cost of capital is 12 per cent. Ignore taxation. 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, and 2 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
