Final answer:
The statement in question is false. The debt ratio measures the percentage of a company's assets that are financed through debt, not the proportion of stockholders' equity financed with debt.
Step-by-step explanation:
The statement "The debt ratio considers the proportion of all stockholders' equity that is financed with debt" is false. The debt ratio is a financial ratio that indicates the percentage of a company's assets that are provided via debt. It is calculated by dividing the total liabilities by the company's total assets, not by stockholders' equity. Stockholders' equity represents the equity of a company's shareholders and is not directly used to measure the proportion of assets financed with debt.
