Group rules carry each type’s asset subtotal, its share of the reporting total, and its median ROE / NPL / NIM / CAR — so every bank reads against its own peers, not the sector. History bar is quarters filed out of 17. An amber period marks a bank that has not filed 2026Q1. Ratios are at the record quarter; a bank that has not filed it shows “—”. Takasbank shows no share by rule, not by omission.
