The rule in plain words

In Part 1: Overview (SR808.01.08.01): either "There has been no use of the exemptions in articles 14(2), 14(3) and 14(5) of the Order during this reporting period" in column "Current period" (row 030, column 010) is "No use of the exemptions in articles 14(2), 14(3) and 14(5) of the Order" and 19 rows (listed below) in column "Current period" (column 010) in Excluded activities and prohibitions Risk management transactions Part 4: Exposure to Financial Institutions - for hedging risk (articles 14(2), 14(3) and 14(5)) (SR808.01.08.04) is left empty, or "There has been no use of the exemptions in articles 14(2), 14(3) and 14(5) of the Order during this reporting period" in column "Current period" (row 030, column 010) is "Use of the exemptions in articles 14(2), 14(3) and 14(5) of the Order" and 19 rows (listed below) in column "Current period" (column 010) in Excluded activities and prohibitions Risk management transactions Part 4: Exposure to Financial Institutions - for hedging risk (articles 14(2), 14(3) and 14(5)) (SR808.01.08.04) is reported.

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.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Report these values together, or leave them all out.
  3. 03It runs only when your filing indicators mark SR808.01.08 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
