From inception of operations to December 31, 2012, Fortner Corporation provided for uncollectible accounts receivable under the allowance method: provisions were made monthly at 2% 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 $130,000 at January 1, 2012. During 2012, credit sales totaled $9,000,000, interim provisions for doubtful accounts were made at 2% of credit sales, $90,000 of bad debts were written off, and recoveries of accounts previously written off amounted to $15,000. Fortner installed a computer system in November 2012, and an aging of accounts receivable was  prepared for the first time as of December 31, 2012. A summary of the aging is as follows.

Based on the review of collectibility of the account balances in the “prior to 1/1/12” aging category, additional receivables totaling $60,000 were written off as of December 31, 2012. The 80% uncollectible  estimate applies to the remaining $90,000 in the category. Effective with the year ended December 31, 2012, 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.
