What is one key aspect of working capital?

Working capital primarily refers to the funds that are available for short-term financial commitments. It represents the liquidity available to a company to meet its day-to-day operational expenses and immediate financial obligations. This is a crucial aspect of managing a business's finances, as it determines the company’s capability to continue its operations and to cover short-term liabilities, such as salaries, accounts payable, and any other short-term debts.

In contrast, the other choices focus on different aspects of financial management. Total revenue is a measure of the income generated by a company from its operations over a specific period and does not directly relate to short-term liquidity. Funds for long-term investments pertain to capital expenditures and the financial resources dedicated to long-term growth, rather than the immediate financial needs. Expenses incurred during the year refer to various costs a company has faced during its operations but do not specifically address the availability of funds for short-term commitments. Overall, understanding working capital is essential for maintaining solvency and operational efficiency.
