(LR4) Alternative breakdown of leverage ratio exposure measure components: Off-balance sheet items, derivatives, SFTs and trading book: a value must not be more than another (LV43.00.00.01, LV47.00.00.01, Bank of England check v4468_m)

A blocking check on the (LR4) Alternative breakdown of leverage ratio exposure measure components: Off-balance sheet items, derivatives, SFTs and trading book (LV43.00.00.01) and leverage ratio calculation (LRCalc) (LV47.00.00.01) templates, 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 exposure value of other assets belonging to the trading book must be less than or equal to the total exposure value of other assets.

In (LR4) Alternative breakdown of leverage ratio exposure measure components: Off-balance sheet items, derivatives, SFTs and trading book (LV43.00.00.01): "Other assets belonging to the trading book" in column "Leverage Ratio Exposure Value" (row 0070, column 0010) must not be more than "Other assets" in column "LR Exposure: Reporting reference date" (row 0190, column 0010) in Leverage ratio calculation (LRCalc) (LV47.00.00.01).

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.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark LV43.00.00.01 and LV47.00.00 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
