Additionally, σbiis a measure of the typical size of asset speciﬁc risk. Given the variance decomposition var(Rit)=β2ivar(RMt)+var(εit)=β2iσ2M + σ2i R2 can be estimated using R2 = βˆ2 iσˆ2M vard(Rit) 3. Let's contrast counterparty risk to loan default risk. If Bank A loans $10 million to Customer C, Bank A charges a yield that includes compensation for default risk. But the exposure is easy to ascertain; it's roughly the invested (funded) $10 million.
