Our new computer system cost us $100,000. We will outgrow it in five years. When we sell it, we will probably get only 20 percent of the purchase price. CCA on the computer will be calculated at a 30 percent rate (Class 10). Calculate the CCA and UCC values for five years. What will be the after-tax proceeds from the sale assuming the asset class is continued? Assume a 40 percent tax rate.
