1. The capital requirement for subsidence risk shall be equal to the loss in basic own funds of insurance and reinsurance undertakings that would result from an instantaneous loss of an amount that, without deduction of the amounts recoverable from reinsurance contracts and special purpose vehicles, is equal to the following:
L_{\mathrm{subsidence}} = 0.005 \cdot \sqrt{\sum_{(i,j)} \mathrm{Corr}_{(\mathrm{subsidence},i,j)} \cdot \mathrm{WSI}_{(\mathrm{subsidence},i)} \cdot \mathrm{WSI}_{(\mathrm{subsidence},j)}}
where:
the sum includes all possible combinations of risk zones (i,j) of France set out in Annex IX;
Corr(subsidence,i,j)denotes the correlation coefficient for subsidence risk in risk zonesiandjset out in Annex XXVI;
WSI(subsidence,i)andWSI(subsidence,j)denote the weighted sums insured for subsidence risk in risk zonesiandjof France set out in Annex IX.
2. For all subsidence zones the weighted sum insured for subsidence risk in a particular risk zone i of France set out in the Annex IX shall be equal to the following:
\mathrm{WSI}_{(\mathrm{subsidence},i)} = \mathrm{W}_{(\mathrm{subsidence},i)} \cdot \mathrm{SI}_{(\mathrm{subsidence},i)}
where:
W(subsidence,i)denotes the risk weight for subsidence risk in risk zoneiset out in Annex X;
SI(subsidence,i)denotes the sum insured of the insurance or reinsurance undertaking for lines of business 7 and 19 as set out in Annex I in relation to contracts that cover subsidence risk of residential buildings in subsidence zonei.
