CACKapitaladäquanz (CET1)

Common Equity Tier 1 ratio for {legal_name} (latest disclosed). EXTRACTION RULES: This index is calibrated for the CET1 percentage scale (typically 8-20%). Cite the Pillar 3 disclosure OR the bank's latest quarterly results OR ECB SSM data hub. Return exact_numerical{value: <cet1_ratio_pct>, unit: "percent", source_urls: [Pillar 3 + supervisor URL]}. Server applies ratio_band (<10→25, 10-12→50, 12-14→70, 14-18→85, 18+→95) — higher CET1 = stronger capital buffer. INSURERS (Solvency II): the SCR coverage ratio lives on an INCOMPATIBLE scale (100% = exactly meeting the requirement, healthy insurers sit at 150-250%); feeding a raw SCR ratio into the CET1 bands above would trivially score a weak 100%-SCR insurer as 95. DO NOT map an SCR ratio onto these CET1 bands. If {legal_name} is an insurer whose only capital metric is an SCR coverage ratio, return type="absent" reason="scr_scale_not_comparable_to_cet1" (handled as a clean not_applicable). PURE ASSET / FUND MANAGERS are not subject to bank CET1 (they fall under IFR/IFPR own-funds or a local net-capital rule); if {legal_name} reports no CET1 ratio, return type="absent" reason="not_disclosed" — NEVER fabricate a CET1 figure for a firm that does not report one.
