How each reporting item is derived is documented only in the formulas of a workbook that has grown over the years.
Balances come from the core banking system, risk weights from the risk system, accruals from the ERP. It all comes together in a workbook nobody would build from scratch today. When an item stands out in the plausibility check, the question of where the number came from is harder to answer than the number itself.

What used to make up most of the reporting work, gathering the 27 items from three systems, shrinks to a single run with a source for every row and delivers the 70% reduction in reporting effort.
The 70% reduction in reporting effort is this agent's headline figure. Twenty-seven reporting items and a window of four working days reflect a typical quarterly run; they are not measured values.
