(5 marks) INFORMATION The management of Torga Limited is considering two investment opportunities: The first alternative involves the purchase of new machinery for R1 200000 which will enable the company to modernise its production facility. The machinery is expected to have a useful life of five years and no salvage value is anticipated. On the day Torga Limited purchases the new machinery, it would also pay the supplier R60 000 for installation costs. The modernisation is expected to increase efficiency, resulting in a reduction in annual cash operating expenses of R380 000 . The second alternative involves purchasing a truck. The truck costs R1 200 000. Its useful life is expected to be five years and a salvage value of R300 000 is anticipated. Operating the truck will necessitate an increase of R60 000 in the company's working capital base immediately upon buying the truck. The working capital cash outflow is expected to be recovered at the end of the truck's useful life. The truck is expected to generate R730 000 per year in additional cash revenues. The driver's salary and other cash operating expenses are expected to be R360 000 per year. Torga Limited desires a rate of return of 12%. The straight-line method of depreciation is used. Ignore taxes. APPENDIX 1: PRESENT VALUE OF R1 APPENDIX 2 : PRESENT VALUE OF A REGULAR ANNUITY OF R1 PER PERIOD FOR N PERIODS
