Probability of default : Covered bonds are structured to survive an issuer event of default and not to
accelerate automatically. As a result, the conditional probability of default (PD) of a covered bond (the
product if the issuer’s PD and the probability of payment interruptions on the covered bonds post issuer
default) should typically be lower than the senior unsecured PD, which represents the cap for the covered
bond PD. The strength of the covered bond framework plays a major role here. This includes provisions
for an effective segregation of cover assets and privileged derivatives in an insolvency scenario as well as
(structural) features to mitigate liquidity risks such as liquidity buffers or different repayment structures
