Spurred by the financial crisis, the importance of thoroughly understanding and measuring counterparty credit risk has become obvious. This thesis, therefore, deals with the concept of bilateral credit valuation adjustment (BCVA) to price the counterparty credit risk on an over-the-counter (OTC) credit derivative. Furthermore, the concept of collateralization is introduced as a way to reduce counterparty credit risk. In this context, the issue of rehypothecation is discussed. Including collateral, a general formula for the bilateral collateralized credit valuation adjustment (BCCVA) is derived and applied on a credit default swap (CDS). A reduced form stochastic intensity model for pricing of the BCCVA is implemented where default dependence is described by a copula function. In numerical simulations the impact of using collateral on the BCVA is analysed under different settings of correlation and credit quality. Also the impact of rehypothecation is discussed. Finally, the model is extended to allow for a portfolio of CDS and results are reported and discussed for the case of two CDS. Also, the impact of netting is examined.
