SimmConcentrationBase()

SimmConcentrationBase

(

)

Default ctor. May need to generalise if units of threshold quotation change significantly

Member Function Documentation

threshold()

QuantLib::Real threshold ( const CrifRecord::RiskType & riskType, const std::string & qualifier ) const

overridevirtual

Early versions of SIMM did not have concentration thresholds assigned. This base class just returns the maximum real number i.e. effectively no concentration threshold

Implements SimmConcentration.

Reimplemented in SimmConcentrationCalibration.

thresholdImpl()

QuantLib::Real thresholdImpl ( const QuantLib::ext::shared_ptr< SimmBucketMapper > & simmBucketMapper, const CrifRecord::RiskType & riskType, const std::string & qualifier ) const

protected

Shared threshold implementation for derived classes to call

Member Data Documentation

flatThresholds_

std::map<CrifRecord::RiskType, QuantLib::Real> flatThresholds_

protected

Map from SIMM RiskType to another map that holds the SIMM concentration threshold bucket to threshold value mappings

bucketedThresholds_

std::map<CrifRecord::RiskType, std::map<std::string, QuantLib::Real> > bucketedThresholds_

protected

Map from SIMM RiskType to another map that holds the SIMM concentration threshold bucket to threshold value mappings

irCategories_

std::map<std::string, std::set<std::string> > irCategories_

protected

Map defining the currency groupings for IR concentration thresholds i.e. key is the category and value is the set of currencies in that category.

fxCategories_

std::map<std::string, std::set<std::string> > fxCategories_

protected

Map defining the currency groupings for concentration thresholds i.e. key is the category and value is the set of currencies in that category.
