The rule in plain words
Firms that use the alternative approach cannot use the BA-CVA or the SA-CVA approach
In column "Methodologies used by the firm (Yes/No)" (0010) of Credit valuation adjustment: CVA exposures by approach - Authorisations (CVA) (OF25.01.01.01): if "Alternative approach" (row 0040) is true, "SA-CVA" (row 0030) must equal false, and "'Full' BA-CVA" (row 0020) must equal false, and "'Reduced' BA-CVA" (row 0010) must equal false.
What to do if your return fails it
- 01Open the table below and find the cells the rule reads.
- 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
- 03It runs only when your filing indicators mark OF25.01.01.01 as reported.
- 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
