1. The risk-weighted exposure amounts for credit risk for exposures belonging to one of the exposure classes referred to in points (a) to (e) and (g) of 147(2) shall, unless deducted from own funds, be calculated in accordance with Sub-section 2 except where those exposures are deducted from Common Equity Tier 1 items, Additional Tier 1 items or Tier 2 items.
