A Balance Sheet is a financial statement that provides a snapshot of a company's assets, liabilities, and shareholders' equity at a specific point in time. It follows the formula: Assets = Liabilities + Shareholders' Equity. Key components include current and non-current assets, current and long-term liabilities, and equity. The Balance Sheet helps businesses and investors evaluate financial stability, liquidity, and capital structure. It's essential for assessing the company's ability to meet its obligations and fund future operations.
