Aggregate weighted-average repricing date under the EBA 5-year cap, with core balance shown as a linear straight-line run-off. Core and non-core proportions sum to 100% of the book.
Core balance is shown as a linear straight-line run-off: the balance declines uniformly from its starting proportion at t=0 to zero at the run-off endpoint. The weighted-average repricing date of this profile is half the endpoint. Non-core is a point mass at t=0; it is shown here as a small wedge for visibility, but in the calculation it reprices instantaneously. The cap operates on the aggregate weighted-average repricing date, not on the shape of the run-off; different distributions producing the same weighted average are equally compliant.
