We devise simulation/regression numerical schemes for pricing the CVA on CDO tranches, where CVA stands for Credit Valuation Adjustment, or price correction accounting for the defaultability of a counterparty in an OTC derivatives transaction. This is done in the setup of a continuous-time...

The paper proposes a new methodology for bootstrapping a single-tranche CDO and estimating the term structure of expected loss. If for a CDS swap there is a clear established standard in the face of the ISDA CDS Standard Model that relies on a survival curve based on default intensity, for a CDO...

In the first part we consider a dynamical model for the number of defaults of a pool of names. The model is based on the notion of generalized Poisson process, allowing for more than one default in small time intervals, contrary to many alternative approaches to loss modeling. We illustrate how...

We discuss in detail the mapping methodology for the valuation of bespoke single tranche Collateralized Debt Obligations in the context of the stochastic recovery gaussian factor modelling framework recently proposed by Amraoui and Hitier (2008)

Modeling the portfolio credit risk is one of the crucial issues of the last years in the financial problems. We propose the valuation model of Collateralized Debt Obligations based on a one- and two-parameter copula and default intensities estimated from market data. The presented method is used...

Several models of how to price synthetic CDOs are presented. The study focuses on comparison of classical Gaussian copula with NIG copula, double t-copula and gaussian stochastic correlation model. Because the the t-copula is technically the most demanding of the presented approaches and usually...
