Own funds (CA1): values must agree (CP01.00.04.01, Bank of England check v0185-1_m)

A blocking check on the own funds (CA1) template (CP01.00.04.01), in the capital+ actuals and forecasts (PRA112) return.

Line4 Check runs it on the capital+ actuals and forecasts (PRA112) return, proven on test files, check by check: the same outcome on all eight test files of that return.

Check your file for this rule

The rule in plain words

In each of 10 columns (listed below) of Own funds (CA1) (CP01.00.04.01): "(-) Excess of deduction from Tier 2 (T2) items over T2 Capital" (row 0720) must equal -1 multiplied by "Excess of deduction from T2 items over T2 Capital (deducted in AT1)" (row 0970).

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 CP01.00.04 as reported.
