The balance sheet is also known as the statement of financial position and it reflects the accounting equation. The balance sheet reports a company's assets, liabilities, and owner's (or stockholders') equity at a specific point in time. Like the accounting equation, it shows that a company's total amount of assets equals the total amount of liabilities plus owner's (or stockholders') equity.
The income statement is the financial statement that reports a company's revenues and expenses and the resulting net income. While the balance sheet is concerned with one point in time, the income statement covers a time interval or period of time. The income statement will explain part of the change in the owner's or stockholders' equity during the time interval between two balance sheets.
