Winneconne Company is considering replacing a machine with a book value of P400,000, a remaining useful life of 5 years, and annual straight-line depreciation of P80,000. The existing machine has a current market value of P400,000. The replacement machine would cost P550,000, have a 5-year life, and save P75,000 per year in cash operating costs. If the replacement machine would be depreciated using the straight-line method, the tax rate is 30%, inventory shall increase by P10,000, payables by P5,000, what would be the net investment required to replace the existing machine?
