Leverage ratio: every EBA validation rule in plain words (COREP LR)

COREP and FINREP are the two pillars of European bank supervisory reporting. COREP (common reporting) covers capital, large exposures, leverage and liquidity. FINREP (financial reporting) covers the balance sheet, profit and loss and asset quality. Both are defined by the EBA and travel in XBRL.

EBA's 4.2 package has 59 validation rules for it. Line4 Check runs 57 of them (314 written-out checks): 2 can block a filing and 55 are warnings. EBA has switched 2 off.
