What does a low Expense Ratio signify about a business?

A low Expense Ratio indicates that a business is managing its individual expenses efficiently relative to its total revenue. This efficiency signifies that the company is effectively controlling its operational costs, which can enhance profitability. When a business has a low Expense Ratio, it implies that a smaller portion of its revenue is used to cover expenses, allowing a larger portion to be retained as profit. This demonstrates strong financial management and can positively affect the business's overall performance.

In the context of other options, a high Expense Ratio would suggest increased operational costs or low efficiency in managing expenses, which is contrary to what a low Expense Ratio signifies. While high sales revenue may correlate with a low Expense Ratio in some cases, it is not a direct implication of it, as efficiency in managing costs can exist independently of revenue levels. Therefore, the assertion that a low Expense Ratio reflects high efficiency in managing individual expenses is accurate.
