Which of the following is an example of non-financial data?

Non-financial data refers to information that does not have a direct monetary value but is still essential for assessing the performance and health of a business. Customer satisfaction is a prime example of non-financial data as it reflects how well a company meets the needs and expectations of its clients. High levels of customer satisfaction often lead to customer loyalty and can influence financial outcomes positively over time, but the metric itself does not represent a financial figure like revenue or profits.

In contrast, the other options provided—net income, total assets, and current liabilities—are all financial metrics that directly represent figures on a company's financial statements. Net income indicates the profitability of a business, total assets show the company's resources, and current liabilities reflect short-term obligations. Therefore, these choices do not qualify as non-financial data. Customer satisfaction, however, captures important qualitative aspects of business performance, thus making it the correct choice in this context.
