There is inflation of f= 2% per year. It is currently Year 0. You work for a large engineering services firm based in Victoria. Your firm's real before-tax MARR is 12% per year. Your firm's real after-tax MARR is 9% per year. Apart from these real MARRs, all other values in this question are nominal. Your firm's corporate tax rate is t = 25%. Your firm buys $30,000 of computer hardware, a Class 8 depreciable asset. Class 8 assets have a CRA-set depreciation rate of d= 30% per year. In Year 0, your firm pays $30,000 for the computer hardware. From Year 1 to Year 20 (inclusive), the hardware will provide savings of $15,000 per year. In Year 20, your firm expects to sell (salvage) the used hardware for $2,500. Your firm has many other Class 8 assets, so there is no need to consider terminal loss or recapture. a.
