How do financial statements and ratios reveal a firm’s financial condition and performance?

"The balance sheet represents the financial condition of a firm at one moment in time, in terms of assets, liabilities, and owners’ equity. The key categories of assets are current assets, fixed assets, and intangible assets. Liabilities are divided into current and long-term liabilities. Owners’ equity, the amount of the owners’ investment in the firm after all liabilities have been paid, is the third major category. The income statement is a summary of the firm’s operations over a stated period of time. The main parts of the statement are revenues (gross and net sales), cost of goods sold, operating expenses (selling and general and administrative expenses), taxes, and net profit or loss. A financial statement that provides a summary of the money flowing into and out of a firm during a certain period, typically one year, is a statement of cash flows. Ratio analysis is the calculation and interpretation of financial ratios using data taken from the firm’s financial statements in order to assess its condition and performance. Liquidity ratios measure a firm’s ability to pay its short-term debts as they come due. Profitability ratios measure how well a firm is using its resources to generate profit and how efficiently it is being managed."
