A firm can show positive net income but go bankrupt for several reasons. One reason is that a company may use accounting techniques such as revenue recognition and accruals to inflate its income artificially. For example, a company may recognize revenue before it has been earned or record income from future sales as current income.
Another reason is that a company may have a large amount of debt that it cannot repay. Even if a company is showing positive net income, it may still go bankrupt if it is not generating enough cash flow to service its debt. Additionally, the company may have a large amount of hidden debt, such as off-balance sheet liabilities, that is not reflected in its financial statements but can contribute to its bankruptcy.
24. What Does Working Capital Mean?
Working capital is a financial indicator used to determine a company’s capacity to satisfy its short-term obligations. It is calculated by subtracting current liabilities from current assets. In other words, it represents the amount of a company’s liquid assets available to meet its short-term debt obligations.
Current assets include cash, accounts receivable, and inventory, while current liabilities include accounts payable, taxes payable, and short-term debt. A positive working capital indicates that a company has enough liquid assets to meet its short-term debt obligations. In contrast, a negative working capital means a company does not have enough liquid assets to meet its short-term debt obligations.
25. What Is A Cash Flow Statement?
It shows a company’s cash inflows and outflows over a certain period. It is used to track a company’s cash earned and utilized, as well as to measure its liquidity and financial health.
The cash flow statement is broken into three sections: cash flow from operations, cash flow from investment, and cash flow from borrowing.
The cash flow from the operational activities segment displays the money earned or spent by the company’s basic business operations. This includes cash received from customers, cash paid to suppliers and employees, and cash used for other operating expenses.
The cash flow from investing activities section shows the cash generated or used by the company’s investments in long-term assets such as property, plant, and equipment. This includes cash received from the sale of assets, cash used to purchase assets and cash generated from the sale of investments.
The cash flow from the financing activities section shows the cash generated or used by the company’s financing activities, such as issuing new debt or equity and repaying existing debt. This includes cash received from issuing new shares or bonds, cash used to pay dividends and cash used to repay debt.
