Note 1 : The calculation of EPS was based on weighted average shares outstanding for the year. Note 2 : The calculation formulas of financial analysis are listed as follows: 1. Capital structure (1) Debt ratio = total liabilities / total assets (2) Long-term funds to property, plant and equipment = (total equity + bonds payable +long-term loans) / net worth of property, plant and equipment 2. Liquidity (1) Current ratio = current assets / current liabilities (2) Quick ratio = (current assets – inventory – prepaid expenses – non-current assets held for sale – other current assets) / current liabilities (3) Times interest earned = income before interest and tax / interest expenses 3. Operating performance (1) Average receivables (including accounts receivable and notes receivable arising from business operations) turnover = net sales / average receivables (including accounts receivable and notes receivable arising from business operations) for each period (2) Days sales outstanding = 365 / average receivables turnover (3) Average inventory turnover = cost of sales / average inventory (4) Average payables (including accounts payable and notes payable arising from business operations) turnover = cost of sale / average payables (including accounts payable and notes payable arising from business operations) for each period (5) Average inventory turnover days = 365 / average inventory turnover (6) Property, plant and equipment turnover = net sales / average net worth of property, plant and equipment (7) Total assets turnover = net sales / average total assets 4. Profitability (1) Return on assets = [net income + interest expenses (1- tax rate)] / average total assets (2) Return on stockholders' equity attributable to the parent company = net income attributable to stockholders of the parent / average total equity attributable to the parent company (3) Pre-tax income to paid-in capital = income before tax attributable to stockholders of the parent / paid-in capital (4) Net profit margin = net income / net sales (5) Earnings per share = (net income attributable to stockholders of the parent – preferred shares dividends) / weighted average number of outstanding shares 5. Cash flow (1) Cash flow ratio = net cash provided by operating activities / current liabilities (2) Cash flow adequacy ratio = five-year sum of net cash provided by operating activities / five-year sum of capital expenditures, inventory increase and cash dividend (3) Cash flow reinvestment ratio = (net cash provided by operating activities – cash dividend) / (gross property, plant and equipment + long-term investments + other non-current assets + working capital) 6. Leverage (1) Operating leverage = (net operating revenue – variable operating costs and expenses) / operating income (2) Financial leverage = operating income / (operating income – interest expenses) Note 3 : The company listed on the TWSE or traded on the TPEx shall include in its analysis the updated financial data which are audited or reviewed by a CPA for the most recent period up to the publication date of the annual report: None.
