What occurs when the value of a firm's debt exceeds the value of shareholders' equity?

When a firm's debt exceeds the value of its shareholders' equity, it indicates that the company is highly leveraged and may be at financial risk. This situation can lead to insolvency or bankruptcy if the firm struggles to meet its debt obligations. Additionally, it may signal to investors that the company is taking on excessive risk, potentially resulting in a decline in stock prices and investor confidence. Overall, it can create challenges for the firm's ability to secure additional financing and sustain operations.
