Leverage ratio calculation (LRCalc): values must agree (LV47.00.00.01, Bank of England check boe_b0021)

A blocking check on the leverage ratio calculation (LRCalc) template (LV47.00.00.01), in the leverage ratio (LVR001) return.

Line4 Check runs it on the leverage ratio (LVR001) return, proven on test files, check by check: the same outcome on all eight test files of that return.

The rule in plain words

The CET1 capital surplus/shortfall to the minimum requirement plus buffers must be equal to the amount of CET1 capital reported in row 0520, minus the sum of 2.4375% and the buffers reported in rows 0530 and 0540 multiplied by the total exposure measure reported in row 0300 of this column.

In column "LR Exposure: Reporting reference date" (0010) of Leverage ratio calculation (LRCalc) (LV47.00.00.01): "Surplus (Shortfall) CET1 to 2.4375% minimum CET1 plus buffers" (row 0570) must equal "CET1 capital" (row 0520) minus "Total exposure measure excluding claims on central banks - using a transitional definition of tier 1 capital (leverage)" (row 0300) multiplied by 0.024375 plus "G-SII or O-SII additional leverage ratio buffer rate, as applicable (%)" (row 0530) plus "Countercyclical leverage ratio buffer rate (%)" (row 0540).

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark LV47.00.00 as reported.
