Own funds for SDDTs (CA1 SDDT): value adjustments check (SC01.00.01.01, SC04.00.01.01, Bank of England check boe_b1033_ss)

A warning on the own funds for SDDTs (CA1 SDDT) (SC01.00.01.01) and memorandum items for SDDTs (CA4 SDDT) (SC04.00.01.01) templates, in the own funds for SDDTs (PRA116) return.

Line4 Check runs it on the own funds for SDDTs (PRA116) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

Value adjustments check

In Own funds for SDDTs (CA1 SDDT) (SC01.00.01.01): "(-) Value adjustments due to the requirements for prudent valuation" in column "Amount" (row 0290, column 0010) must equal -0.001 multiplied by "Total fair valued assets and liabilities" in column "Amount" (row 0870, column 0010) in Memorandum items for SDDTs (CA4 SDDT) (SC04.00.01.01).

This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it. It runs only when your filing indicators mark SC01.00.01 and SC04.00.01 as reported.
