Final answer:
The statement about the degree of operating leverage is false; DOL can be computed even when a company is not profitable, offering insights into how sales volume changes affect operating income.
Step-by-step explanation:
The statement that the degree of operating leverage should be computed only over a profitable range of operations is false. The degree of operating leverage (DOL) measures how a company's operating income changes in response to a change in sales. It is defined as the percentage change in operating income divided by the percentage change in sales. While it is important for a company to be profitable, the DOL can be computed and analyzed even when the company is not currently generating a profit. Understanding the DOL can help a company plan and predict the effects of changes in sales volume on profitability, and it is useful in scenarios of both profits and losses.
The concept of operating leverage is critical in understanding cost behavior and how it impacts a firm's earnings. A company with a higher DOL is more sensitive to changes in sales, which means that a small increase in sales can lead to a larger change in operating income. Conversely, a decrease in sales can result in a more significant decrease in operating income for a company with high operating leverage, indicating more risk during economic downturns.
