Article 149
Health risk equalisation systems
The standard deviations for NSLT health premium and reserve risk of segments 1, 2 and 3 in Annex XIV for business that is subject to a HRES shall meet all of the following requirements:
the standard deviations are determined separately for each of the segments 1, 2 and 3, as set out in Annex XIV, and separately for premium and reserve risk;
for each of the segments set out in Annex XIV, the standard deviation for premium risk is the lower of the following amounts:
the standard deviation for NSLT health premium risk of that segment set out in Annex XIV;
the higher of the following amounts:
a third of the standard deviation for NSLT health premium risk of that segment set out in Annex XIV;
an estimate of the representative standard deviation of an insurance undertaking's combined ratio, being the ratio of the following annual amounts:
for each of the segments set out in Annex XIV, the standard deviation for reserve risk is the lower of the following amounts:
the standard deviation for NSLT health reserve risk of that segment set out in Annex XIV;
the higher of the following amounts;
a third of the standard deviation for NSLT health reserve risk of that segment set out in Annex XIV:
an estimate of the representative standard deviation of an insurance undertaking's run-off ratio, being the ratio of the following annual amounts:
the determination of the standard deviation is based on adequate, applicable and relevant actuarial and statistical techniques;
the determination of the standard deviation is based on complete, accurate and appropriate data that is directly relevant for the business subject to the HRES and reflects the average degree of diversification at the level of insurance undertakings;
the determination of the standard deviation is based on current and credible information and realistic assumptions;
the determination of the standard deviation also takes into account any risks which are not mitigated by the HRES, in particular the risk referred to in Article 105(4)(a) of Directive 2009/138/EC and risks which are not reflected in the health catastrophe risk sub-module and that could affect a larger number of insurance undertakings subject to the HRES at the same time;
the methodology for the calculation of the standard deviation and the calculation of the standard deviation is publicly available.
Where only a part of an insurance undertaking's business in a segment s is subject to the HRES, the undertaking shall use a standard deviation for NSLT health premium risk of the segment in the calculation of the standard deviation for NSLT health premium and reserve risk referred to in Article 148(1) that is equal to the following:
where:
σ(prem,s) denotes the standard deviation for NSLT health premium risk segment s set out in Annex XIV;
V(prem,s,nHRES) denotes the volume measure for NSLT health premium risk of the business in segment s that is not subject to the HRES;
σ(prem,s,HRES) denotes the standard deviation for NSLT health premium risk of segment s for business subject to the HRES calculated in accordance with paragraph 2;
V(prem,s,HRES) denotes the volume measure for NSLT health premium risk of business in segment s that is subject to the HRES.
V(prem,s,HRES) and V(prem,s,nHRES) shall be calculated in the same way as the volume measure for NSLT health premium risk of segment s referred to in Article 147, but V(prem,s,HRES) shall only take into account the insurance and reinsurance obligations subject to HRES and V(prem,s,nHRES) shall only take into account the insurance and reinsurance obligations not subject to the HRES.
Where only a part of an insurance undertaking's business in a segment s is subject to the HRES, the undertaking shall use a standard deviation for NSLT health premium risk of the segment in the calculation of the standard deviation for NSLT health premium and reserve risk referred to in Article 148(1) that is equal to the following:
where:
σ(res,s) denotes the standard deviation for NSLT health reserve risk segment s as set out in Annex XIV;
V(res,s,nHRES) denotes the volume measure for NSLT health reserve risk of the business in segment s that is not subject to the HRES;
σ(res,s,HRES) denotes the standard deviation for NSLT health reserve risk of segment s for business subject to the HRES calculated in accordance with paragraph 2;
V(res,s,HRES) denotes the volume measure for NSLT health reserve risk of business in segment s that is subject to the HRES.
V(res,s,nHRES) and V(res,s,HRES) shall be calculated in the same way as the volume measure for NSLT health reserve risk of segment s referred to in Article 147, but V(res,s,HRES) shall only take into account the insurance and reinsurance obligations subject to the HRES and V(res,s,nHRES) shall only take into account the insurance and reinsurance obligations not subject to the HRES.
