Final answer:
The question is about calculating the estimated uncollectible accounts for Oak Ridge Ltd. using an aging schedule. To complete this, one would categorize accounts by how long they've been outstanding and apply uncollectibility percentages for each category. However, these percentages are not provided.
Step-by-step explanation:
The question relates to the preparation of an aging schedule for accounts receivable by Oak Ridge Ltd. and involves calculating the total estimated uncollectible accounts based on this schedule. An aging schedule is typically employed by businesses to manage and estimate bad debts by categorizing accounts receivable according to the duration the amount has been outstanding. This is crucial for estimating the allowance for doubtful accounts, which is a contra-asset account reducing the total receivables on the balance sheet to reflect what is expected to be collectible.
To calculate the total estimated uncollectible accounts, we would classify the ending balance of each account based on how long they have been outstanding. Then, we would apply the appropriate percentage that is uncollectible to each aging category (for example, 1% of receivables within 30 days might be considered uncollectible, while 20% might be uncollectible if they are over 90 days due).
However, since the specific percentages for the aging periods are missing in this question, we cannot complete the calculation. The existing unadjusted credit balance in the Allowance for Doubtful Accounts of $12,810 would also typically factor into the adjustment of the bad debts expense for the month of July.
