Balance Sheet
Definition
The balance sheet is a snapshot of a company's financial position at a single point in time, organized around the identity Assets = Liabilities + Shareholders' Equity. Assets are resources the company controls (cash, receivables, inventory, PP&E, goodwill); liabilities are obligations (payables, accrued expenses, debt, deferred taxes); equity is the residual claim (common stock, additional paid-in capital, retained earnings, and other items).
Items are split into current (expected to convert or come due within one year) and non-current. Many assets are carried at historical cost less depreciation rather than market value, which is why book equity usually differs from market capitalization.
In interview mechanics, every change on the other two statements must keep the balance sheet balanced — cash changes flow from the cash flow statement, and net income flows into retained earnings.
Why interviewers ask
Balance sheet questions test whether you can keep the accounting identity intact under stress: "inventory goes up by $10, paid with cash — what happens?" The trap is forgetting the equity plug through retained earnings, or double-counting cash. Interviewers also probe why book value differs from market value.
