Leverage ratio calculation (LRCalc): values must agree (LV47.00.00.01, Bank of England check boe_b0030)

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 leverage ratio including claims on central banks must be equal to: tier 1 capital (leverage) * total exposure measure including claims on central banks.

In each of "LR Exposure: Reporting reference date" (column 0010) and "Daily/Monthly Average over the reporting quarter (LREQ firms only)" (column 0020) of Leverage ratio calculation (LRCalc) (LV47.00.00.01): "Leverage Ratio including claims on central banks - using a transitional definition of tier 1 capital (leverage)" (row 0342) multiplied by "Total exposure measure including claims on central banks - using a transitional definition of tier 1 capital (leverage)" (row 0282) must equal "Tier 1 capital (leverage) - transitional definition" (row 0320).

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.
