(LR4) Alternative breakdown of leverage ratio exposure measure components: Other non-trading book exposures (SA): a total must equal the sum of its parts (LV43.00.00.02, Bank of England check v0701_m)

A blocking check on the (LR4) Alternative breakdown of leverage ratio exposure measure components: Other non-trading book exposures (SA) template (LV43.00.00.02), 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 exposures to regional governments, MDBs, international organisations and PSEs not treated as sovereigns must equal to the sum of the values reported in rows 0150, 0160 and 0170 of this column.

In each of "Leverage Ratio Exposure Value: SA Exposures" (column 0010) and "RWEA: SA exposures" (column 0030) of (LR4) Alternative breakdown of leverage ratio exposure measure components: Other non-trading book exposures (SA) (LV43.00.00.02): "Exposures to regional governments, MDBs, international organisations and PSEs NOT treated as sovereigns" (row 0140) must equal the sum of "Regional governments and local authorities NOT treated as sovereigns" (row 0150), "MDBs NOT treated as sovereigns" (row 0160) and "PSEs NOT treated as a sovereigns" (row 0170).

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 table below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark LV43.00.00.02 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

Which returns it applies to

Line4 Check runs it on the leverage ratio (LVR001) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to leverage ratio (LVR001) returns, as a blocking check.

The Bank’s own words and formula

The first paragraph of the plain words above is the Bank of England’s own, word for word, from its list of validations. The second spells out its formula, with each cell named from its templates.

Show the formulaShow

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.

{t: LV43.00.00.02, r: 0140} = sum({t: LV43.00.00.02, r: 0150; 0160; 0170})

Where it applies, in the Bank's words (its scope):

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
