Resolution planning: critical functions and services: every EBA validation rule in plain words (RESOL2)

Resolution reporting gives resolution authorities the data to plan how a failing bank could be resolved in an orderly way: its legal entities, liabilities, critical functions and links to market infrastructure. MREL and TLAC reporting shows whether it holds enough capacity to absorb losses. Both use EBA templates and travel in XBRL.

EBA's 4.2 package has 46 validation rules for it. Line4 Check runs 26 of them (295 written-out checks): 0 can block a filing and 26 are warnings. EBA has switched 1 off. 19 are not run yet.
