From its first day of operations to December 31, 2020, Flint Corporation provided for uncollectible accounts receivable under the allowance method: 1. Entries for bad debt expense were made monthly based on 2.0% of credit sales. 2. Bad debts that were written off were charged to the Allowance for Doubtful Accounts. 3. Recoveries of bad debts previously written off were credited to the allowance account No year and adjustments were made to the allowance account. The balance in Allowance for Doubtful Accounts was $187.000 at January 1, 2020. During 2020, credit sales totalled $9.2 million, interim entries for bad debt expense ware based on 2.09% of credit sales. 895,000 of bad debts were written off, and recoveries of accounts previously written off amounted to $18,000. Flint upgraded its computer facility in November 2020, and an aging of accounts receivable was prepared for the first time as at December 31, 2020. Campbell's usual credit terms were nst 30 days, and remain unchanged A summary of the aging analysis follows: Balance in Each Category Estimated Uncollectible Classification by Month of Sale November December 2020 $1,060,000 July-October 2020 490,000 12.05 January-June 2020 470,000 30% Before January 1, 2020 131000 70% $2,251,000 Based on a review of how collectible the accounts really are in the "Before January 1, 2020' aging category, additional receivables totalling $73.000 were written off as at December 31, 2020. The 70% uncollectible estimate therefore only applies to the remaining $50,000 in the category. Finally, beginning with the year ended December 31, 2020, Flint adopted a new accounting method for estimating the allowance for doubtful accounts: it now uses the amount in the year-end aging analysis of accounts receivable.
