Spade Agency separates its accounts receivable into three age groups for purposes of estimating the percentage of uncollectible accounts.

1. Accounts not yet due = $25,000; estimated uncollectible = 4%.

2. Accounts 1–60 days past due = $10,000; estimated uncollectible = 25%.

3. Accounts more than 60 days past due = $5,000; estimated uncollectible = 50%.

In addition, the balance of Allowance for Uncollectible Accounts before adjustment is $1,000 (credit). Compute the total estimated uncollectible accounts and record the year-end adjustment.
