Answer: Decrease assets and decrease stockholders' equity
Explanation:
If ABC estimates the uncollectible accounts based on the percentage of accounts receivable, the effect that the recording of the estimate of the uncollectible accounts will have on the accounting equation is that there will be a decrease in assets and there'll also be a decrease in the stockholders' equity.
We should note that the accounts uncollectible simply refers to the loans, receivables or other forms of debt that there's no chance of it being paid. Therefore, when they are estimated based on the percentage of accounts receivable, there'll be a reduction in both the assets and the stockholders equity.
