Contra Accounts

This question tests whether you understand how certain balance sheet accounts reduce the reported value of related liabilities, assets, or equity rather than increasing them. Interviewers ask this because it checks core accounting mechanics, presentation on the financial statements, and the candidate’s ability to explain why some accounts carry an opposite normal balance from the line item they offset.

It also reinforces how accounting treatments tie into real transactions, such as debt issuance costs, depreciation, and treasury stock. In an investment banking interview, being able to identify these account types and explain their purpose shows that you understand both the financial statements and the economic meaning behind the entries.
