From inception of operations to December 31, 2014, Fortner Corporation provided for uncollectible accounts receivable under the allowance method: Provisions were made monthly at 1% of credit sales; bad debts written off were charged to the allowance account; recoveries of bad debts previously written off were credited to the allowance account, and no year-end adjustments to the allowance account were made. Fortner's usual credit terms are net 30 days. The balance in Allowance for Doubtful Accounts was $149,700 at January 1, 2014. During 2014, credit sales totaled $9,145,900, interim provisions for doubtful accounts were made at 1% of credit sales, $91,459 of bad debts were written off, and recoveries of accounts previously written off amounted to $15,600. Fortner installed a computer system in November 2014, and an aging of accounts receivable was prepared for the first time as of December 31, 2014. A summary of the aging is as follows. Based on the review of collectibility of the account balances in the "prior to 1/1/14" aging category, additional receivables totaling $61,400 were written off as of December 31, 2014. The 82% uncollectible estimate applies to the remaining $93,300 in the category. Effective with the year ended December 31, 2014, Fortner adopted a different method for estimating the allowance for doubtful accounts at the amount indicated by the year-end aging analysis of accounts receivable.
