Consolidated (CFS), from DART. 11 fiscal years and 10 quarters. Accounts matched on IFRS account_id, not Korean labels, so the same line holds across years where the Korean wording changed. Quarterly figures are three-month values: income quarters from DART's three-month column, cash-flow quarters differenced from DART's cumulative figures, and Q4 as annual minus nine-month cumulative.
