Balance sheet: technical provisions - total = best estimate + risk margin - TMTP (IRR.02.01, Bank of England rule IR_bv0244_03)

A blocking check on the balance sheet template (IRR.02.01), in the annual solo (ARS) and annual group (ARG) returns.

The rule in plain words

Technical provisions - total = best estimate + risk margin - TMTP

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 IRR.02.01 as reported.
