Pro_rata

Pro-rata capital allocation

Naming pattern: Measures with “Pro-rata” behavior follow the name pattern:Main Measure Name Pro-Rata.

Pro-Rata is one of the approaches implemented in the FRTB Accelerator to decompose a non-linear measure down to additive components.

Depending on the specified context values, a Pro-Rata measure behaves as:

In both methods the charge computed at ReferenceLevel is decomposed into additive components. Additionally, the impact of query filters on the results can be controlled using ReferenceLevelVisualTotalsMode.

The main difference between the approaches is that the capital allocation per “Russian Doll” method will take into account the netting within aggregation nodes, wheres in bottom-up approach only the leaf-level netting matters.
