Principles for business line mapping

6. All activities should be mapped into the eight level 1 business lines in a mutually exclusive and jointly exhaustive manner.
7. Any activity which cannot be readily mapped into the business line framework, but which represents an ancillary function to an activity included in the framework, should be allocated to the business line it supports. If more than one business line is supported through the ancillary activity, an objective mapping criteria should be used.
8. When mapping gross income, if an activity cannot be mapped into a particular business line then the business line yielding the highest charge should be used. The same business line equally applies to any associated ancillary activity.
9. An Authorised Person may use internal pricing methods to allocate gross income between business lines, provided that total gross income for the firm (as would be recorded under the Basic Indicator Approach) still equals the sum of gross income for the eight business lines.
10. The mapping of activities into business lines for Operational Risk capital purposes should be consistent with the definitions of business lines used for regulatory capital calculations in other risk categories, i.e. credit and Market Risk. Any deviations from this principle should be clearly motivated and documented.
11. The mapping process used should be clearly documented. In particular, written business line definitions should be clear and detailed enough to allow third parties to replicate the business line mapping. Documentation should, among other things, clearly motivate any exceptions or overrides and be kept on record.
12. Processes should be in place to define the mapping of any new activities or products and the mapping process to business lines should be subject to independent review.
