In addition, an important aspect of managing valuation risk is associated with model risk. In search of transparency, market participants tend to adopt multiple model approaches and rely on consensus rather than science. In the absence of deep and liquid market transactions, and given the highly non-linear nature of some of the structured products , the mark-to-model process itself requires transparency. To achieve this, open pricing platforms may be linked to the centralised data warehouse. Those platforms are capable of using multiple models, scenarios, data sets with various distribution and dispersion models to price and re-price under ever-changing assumptions.
