ECL: How to Measure Probability of Default

3) LGD calculation is made from the same receivables data used in PD which has already taken the recoveries impact in flow rate. LGD has to be calculated in a performance window from recoveries of actual defaults. The calculation should be on data after an account has defaulted and it should include the legal and other costs as well.

Gradient corrections in density functional theory calculations for

Ab initio total energy calculations have been performed for CO chemisorption on Pd{110}. Local density approximation (LDA) calculations yield chemisorption energies which are significantly higher than experimental values but inclusion of the generalised gradient approximation (GGA) gives better agreement.
