Refer back to the section of the chapter entitled “Preparing Adjusting Entries.” Who determines how long buildings and furniture and equipment are to last? Who determines the dollar amount of accounts receivable that are doubtful? Suppose we were to change our asset depreciation on the buildings and the furniture and equipment from 5% and 10%, to 4% and 8%, respectively. What would be the effect on net income? Would it increase or decrease? Likewise, suppose our estimate of the balance in Allowance for Bad Debts was reduced to $1,000. What would be the effect on net income? Is the adjusting entry process an exact science where accountants can determine exactly how well a company has done for a period? Or is accounting an art that requires significant judgment on the part of the accountant? What are the dangers for the accountant when making an estimate in an area (like Bad Debts) where significant judgment is required?
