Application of Stochastic Mesh Method to Efficient Approximation of CVA

In this paper, the author considers the numerical computation of CVA for large systems by Mote Carlo methods. He introduces two types of stochastic mesh methods for the computations of CVA. In the first method, stochastic mesh method is used to obtain the future value of the derivative contracts. In the second method, stochastic mesh method is used only to judge whether future value of the derivative contracts is positive or not. He discusses the rate of convergence to the real CVA value of these methods.
