For a company with total debt of $225 million, which of the following amounts would indicate a complete lack of equity?

A complete lack of equity in a company indicates that the company's total liabilities are equal to the total debt, with no shareholders' equity contributing value to the business. In this scenario, if a company has total debt of $225 million, the absence of any equity would be represented by a total equity amount of $0.

When equity is zero, it means that the company has effectively financed its entire capital structure exclusively through debt, leading to a situation known as being "capitalized solely by debt." This often raises concerns about financial stability and the risk of insolvency, particularly if the company experiences losses.

The other figures presented reflect varying amounts of equity, indicating that in these cases, the company has some level of ownership interest or investment from shareholders, which is not reflective of a complete lack of equity. Thus, the only choice that accurately represents a complete absence of equity is $0.
