Final answer:
Using the direct write-off method, the write-off of an uncollectible account receivable causes a c. decrease in both net income and total assets, due to the credit to accounts receivable and the debit to bad debt expense.
Step-by-step explanation:
If a company writes off an account receivable under the direct write-off method, the entry to write off the account directly reduces the account receivable and the net income by debiting bad debt expense and crediting accounts receivable. This means that the correct answer is that there will be a decrease in net income; however, the total assets will also decrease because the accounts receivable (an asset) is reduced. Hence, when an account receivable is deemed uncollectible and is written off, it results in a simultaneous reduction of assets and net income.
