A blocking check on the (LR8) Treatment of agency repurchase transactions template (LV51.00.00.01), in the contingent leverage (LVR002) return.

Check your file for this rule

The rule in plain words

'Contribution to Leverage Exposure Measure (period end)' for ' Agency repo activity in which agent provides a limited guarantee' amount is the higher value of zero and the difference between 'Collateral provided to lender by borrower (period end)' & 'Total loan from lender to borrower'

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 LV51.00.00 as reported.

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

{t: LV51.00.00.01, r: 0010, c: 0030} = imax(0, {t: LV51.00.00.01, r: 0010, c: 0020} - {t: LV51.00.00.01, r: 0010, c: 0010}, {t: LV51.00.00.01, r: 0010, c: 0010} - {t: LV51.00.00.01, r: 0010, c: 0020})
