Large exposures: every EBA validation rule in plain words (COREP LE)

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 25 validation rules for it. Line4 Check runs 24 of them (88 written-out checks): 0 can block a filing and 24 are warnings. 1 are not run yet.

Their EBA formulas need parts of the XBRL formula language Line4 Check does not cover yet. Your authority's validation runs them.
