The rule in plain words

The Tier 1 capital surplus/shortfall to the minimum requirement must be equal to the amount of Tier 1 capital reported in row 0320, minus 3.25% of the total exposure measure reported in row 0300 of this column.

In column "Daily/Monthly Average over the reporting quarter (LREQ firms only)" (0020) of Leverage ratio calculation (LRCalc) (LV47.00.00.01): "Surplus (Shortfall) Tier 1 to 3.25% minimum Tier 1 requirement" (row 0560) must equal "Tier 1 capital (leverage) - transitional definition" (row 0320) minus "Total exposure measure excluding claims on central banks - using a transitional definition of tier 1 capital (leverage)" (row 0300) multiplied by 0.0325.

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.
