Preparation Notes: 1. The company applies IFRS accounting standards. 2. The functional currency is USD. TWD figures are converted using the average exchange rate for the period. However, valuation gains/losses are calculated using the end-of-period exchange rate. 3. Year-on-year changes are calculated based on USD financial figures. 4. Earnings per share (EPS) is calculated using the weighted average number of shares outstanding. 5. Depreciation and crew wages are recognized monthly, while charter revenue is recognized on a daily accrual basis, so operating days may affect revenue and operating profit. 6. Lubricant expenses are estimated monthly and adjusted quarterly based on actual consumption. 7. Depreciation periods vary by vessel condition, tonnage, and specifications, but new vessels are generally depreciated over 25 years. Salvage value is estimated by multiplying light ship weight by scrap metal prices. 8. This financial information is self-compiled and has not been audited or certified by an accountant.
