Installment Jewelry Company has been in business for 5 years but has never had its financial statements audited. Engaged to audit them for 2019, you find that the companys balance sheet carries no allowance for bad accounts. Bad accounts have been expensed as written-off and recoveries credited to income as collected. The companys policy is to write off at December 31 of each year those accounts on which no collections have been received for three months. The installment contracts generally are for 2 years. On your recommendation, the company agrees to revise its accounts for 2019 to give effect to bad account treatment on the allowance basis. The allowance is to be based on a percentage of credit sales that is derived from the experience of prior years.
