Where a firm's AMA permission allows it to use an advanced measurement approach in combination with either the basic indicator approach or the standardised approach, the FSA may impose additional conditions on a case by case basis as follows:
[Note: BCD Annex X, Part 4 point 2]
the firm has committed to roll out the advanced measurement approach for around 85% (or more) of its operational risk, subject to the remaining percentage not being concentrated in a single operation, within a timescale set out in the AMA permission.
A firm may apply to the FSA for a waiver from BIPRU 6.2.12 R (1) and BIPRU 6.2.12 R (2) in exceptional circumstances, such as the recent acquisition of new business, which require a transition period for the roll out of the standardised approach (or the alternative standardised approach). In this event, a firm will need to make a commitment to roll out the standardised approach (or the alternative standardised approach) within a time schedule agreed with the FSA.
