Abstract
This paper provides an overview of counterparty valuation adjust-
ments, within the context of collateralized and un-collateralized trad-
ing relationships. The counterparty valuation adjustment terms are
derived by decomposing an un-defaultable portfolio into a set of bi-
nary states. These states are a set of market values of the portfolio
(positive or negative), default states (default or no default) and re-
coveries (recover the recovery amount or not). In particular, the asset
charge and liability benefit are formulated for both un-collateralized
and collateralized portfolios while different models are provided for the
collateral transfer calculations of the collateralized trading accounts.
