Final answer:
The understatement of expenses that changes a net loss to a net profit is considered qualitatively material because it affects users' decision-making even though the amount may not be large.
Step-by-step explanation:
During an audit, when an understatement of expenses changes the company's financial status from a net loss to a net profit, the situation is considered to be qualitatively material. The size of the error, in this case, $5,000, may not be large in itself (quantitative materiality), but the fact that it changes the loss to profit has a significant qualitative impact. Materiality in auditing is not solely a mathematical determination; it encompasses the influence on the decision-making process of users of the financial statements.
To illustrate this with a simple example from an accounting profit calculation, suppose a firm has $1 million in sales revenue and incurs expenses including $600,000 on labor, $150,000 on capital, and $200,000 on materials. The firm's accounting profit would be calculated as the total revenues minus the explicit costs, resulting in:
Accounting Profit = $1,000,000 - ($600,000 + $150,000 + $200,000) = $50,000.
