Which of the following is considered a type of senior or bank debt?

Senior or bank debt refers to loans or credit that takes priority over other forms of financing in the event of a liquidation or bankruptcy. This type of debt is typically secured by the borrower's assets and has a higher claim on those assets than other types of debt, which means it is paid first in the hierarchy of debt obligations.

In contrast, common equity represents ownership in a company and does not have repayment priority or claim on assets like debt does. High yield debt, while a type of debt, falls into the category of lower-rated bonds that carry higher risk and higher interest rates, thus typically subordinated to senior debt. Subordinate debt, by definition, is a category of debt that ranks below senior debt in terms of claims on assets, making it riskier and lower in the repayment hierarchy.

Therefore, senior/bank debt is the correct answer because it directly defines the type of financing that is considered senior in priority and structure.
