A warning on the PRA supplementary data section template (SC701.00.03.01), in the capital+ forecast annual for SDDTs and SDDT consolidation entities (PRA118) return.

Line4 Check runs it on the capital+ forecast annual for SDDTs and SDDT consolidation entities (PRA118) return, proven on test files, check by check: the same outcome on all eight test files of that return.

The rule in plain words

Assets and leverage exposures should be positive

In PRA supplementary data section (SC701.00.03.01): every value in "Total balance sheet assets" (row 0270) and "Total Leverage Ratio exposure measure - using a fully phased-in definition of Tier 1 capital" (row 0281) in "Q4" (column 0050), "Q8" (column 0090) and "Year-end following Q8" (column 0100) must be zero or more.

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
  3. 03It runs only when your filing indicators mark SC701.00.03 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
