Preparation Notes: 1. The company applies IFRS accounting standards. 2. The functional currency is USD. TWD amounts are converted using the average exchange rate for the period. However, valuation gains/losses are calculated using the end-of-period exchange rates. 3. Change rates are calculated based on USD-denominated financial figures from the current and prior year periods. 4. Earnings per share (EPS) is calculated using the weighted average number of shares outstanding. 5. Depreciation and crew wages are recognized on a monthly basis, while charter revenue is recognized on a daily accrual basis, meaning operational days can affect revenue and operating profit. 6. Lubricating oil expenses are estimated monthly but 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.
