TWD million, from each year's annual report on the SEC's EDGAR, the year linked to its filing, on the IFRS tags the company filed. A line the company does not file under the standard tag is left out rather than estimated. A year marked * shows the figure as the company restated it in a later annual report (Dec 2020); the first-filed figure is in the CSV. Profit for the year includes the part that belongs to minority shareholders; profit attributable to shareholders is the part EPS is struck on.
