This document discusses ratio analysis, which is an important tool in financial management. Ratio analysis involves calculating and comparing ratios using data from financial statements to evaluate a company's performance. There are three types of ratios: percentage ratios for profitability, turnover ratios computed in times, and simple ratios. Ratios can be classified based on the financial statements used - income statement ratios include gross profit ratio and net profit ratio, while balance sheet ratios include current ratio, debt-equity ratio, and fixed asset turnover ratio. Ratio analysis allows management to compare results over different periods and between companies.
