title: "Solvency II SCR Standard-Formula Module Aggregator"
description: "Aggregates the five Solvency II standard-formula risk-module capital charges (market, counterparty default, life underwriting, health underwriting, non-life underwriting) into Basic SCR via the Delegated Regulation (EU) 2015/35 Annex IV correlation matrix, then adds the operational risk charge and subtracts the loss-absorbing adjustment (deferred tax/technical provisions) to produce total SCR. Delta over calculate_solvency2_scr_ratio (art-180), which takes `scr` as a given input and does not derive it from sub-module charges; feeds art-180's scr input. Not the US NAIC RBC action-level ladder (a different jurisdiction and regime, see compute_rbc_action_level). Solvency II Dir. 2009/138/EC + Del. Reg. (EU) 2015/35 Annex IV. NaN-safe. Zero network, zero PII."
