9.2 Account for Uncollectible Accounts Using the Balance Sheet and Income Statement Approaches

Accounting for Uncollectible Accounts

Direct Write-Off vs. Allowance Method

When customers don't pay, businesses need a way to account for those losses. There are two approaches, but only one follows GAAP for most companies.

Direct Write-Off Method: Bad debt expense is recorded only when a specific account is confirmed uncollectible. The entry debits Bad Debt Expense and credits Accounts Receivable. This method is simple, but it violates the matching principle because the expense often gets recorded in a different period than the revenue that created the receivable. GAAP only permits this method when bad debts are immaterial.

Allowance Method: Instead of waiting for accounts to go bad, this method estimates uncollectible amounts at the end of each period. It satisfies the matching principle because the estimated expense is recognized in the same period as the related credit sales. Two accounts are involved:

• Bad Debt Expense (income statement) captures the estimated loss
• Allowance for Doubtful Accounts (balance sheet) is a contra-asset that reduces the net realizable value of Accounts Receivable

When a specific account is later deemed uncollectible, the write-off entry debits Allowance for Doubtful Accounts and credits Accounts Receivable. Notice that this write-off does not affect total assets or the income statement, because the allowance (a contra-asset) and the receivable both decrease by the same amount.

Methods for Estimating Bad Debt

The allowance method requires an estimate. Companies calculate that estimate using either the income statement approach or the balance sheet approach.

Income Statement Approach (Percentage of Credit Sales)

This method focuses on the current period's credit sales. The formula:

$\text{Bad Debt Expense} = \text{Credit Sales} \times \text{Estimated Uncollectible Percentage}$

For example, if a company has $500,000 in credit sales and historically 2% go uncollected, Bad Debt Expense for the period is $500{,}000 \times 0.02 = \$10{,}000$. The percentage comes from historical data or industry averages.

The key feature: this method calculates the expense directly. Whatever you compute gets recorded as the adjusting entry, regardless of any existing balance in the Allowance account.

Balance Sheet Approach (Aging of Receivables)

This method focuses on the ending Accounts Receivable balance and asks: how much of what's currently owed will we never collect? The formula:

$\text{Bad Debt Expense} = \text{Desired Ending Balance in Allowance} - \text{Current Balance in Allowance}$

The key feature: this method calculates the desired allowance balance first, then works backward to figure out the adjusting entry. If the Allowance account already has a credit balance, the adjustment is smaller. If it has a debit balance (from write-offs exceeding prior estimates), the adjustment is larger.

Balance Sheet Aging of Receivables

The aging schedule is the tool that makes the balance sheet approach work. Here's how to build one:

1. Categorize each receivable by how long it's been outstanding (e.g., Current, 1–30 days past due, 31–60 days past due, 61–90 days past due, over 90 days).
2. Total each category. Add up all receivables that fall into each aging bucket.
3. Assign an uncollectible percentage to each category. Older receivables get higher percentages because they're less likely to be collected. For example, "Current" might be 1%, while "Over 90 days" might be 40%.
4. Multiply each category's total by its estimated uncollectible percentage to get the estimated uncollectible amount per category.
5. Sum all categories. This total is the desired ending balance in Allowance for Doubtful Accounts.
6. Compare to the current Allowance balance and record the difference as Bad Debt Expense.

If the Allowance for Doubtful Accounts currently has a $1,500 credit balance, the adjusting entry for Bad Debt Expense would be $\$11{,}900 - \$1{,}500 = \$10{,}400$. If it instead had a $600 debit balance (from write-offs), the entry would be $\$11{,}900 + \$600 = \$12{,}500$.

Assessing Credit Risk and Receivables Management

Estimating bad debt is part of a broader effort to manage credit risk, which is the potential for loss when customers fail to pay.

Two ratios help evaluate how well a company manages its receivables:

• Receivables Turnover Ratio measures collection efficiency:

$\text{Receivables Turnover} = \frac{\text{Net Credit Sales}}{\text{Average Accounts Receivable}}$

A higher ratio means the company collects receivables more quickly. If net credit sales are $600,000 and average accounts receivable is $50,000, the turnover is 12 times per year.

• Average Collection Period converts that ratio into days:

$\text{Average Collection Period} = \frac{365}{\text{Receivables Turnover}}$

Using the example above: $365 \div 12 \approx 30.4 \text{ days}$. This means it takes about 30 days on average to collect a receivable.

A company's credit policy drives these numbers. Extending credit more liberally can boost sales but increases the risk of uncollectible accounts. Tighter credit policies reduce bad debts but may also reduce revenue. The goal is finding the right balance for the business.
