Mechanics of risk-weighted asset calculation.

(a) If a Board-regulated institution does not qualify to use or does not have qualifying operational risk mitigants, the Board-regulated institution's dollar risk-based capital requirement for operational risk is its operational risk exposure minus eligible operational risk offsets (if any). (b) If a Board-regulated institution qualifies to use operational risk mitigants and has qualifying operational risk mitigants, the Board-regulated institution's dollar risk-based capital requirement for operational risk is the greater of: (1) The Board-regulated institution's operational risk exposure adjusted for qualifying operational risk mitigants minus eligible operational risk offsets (if any); or (2) 0.8 multiplied by the difference between: (i) The Board-regulated institution's operational risk exposure; and (ii) Eligible operational risk offsets (if any). (c) The Board-regulated institution's risk-weighted asset amount for operational risk equals the Board-regulated institution's dollar risk-based capital requirement for operational risk determined under sections 162(a) or (b) multiplied by 12.5.
