A cursory google brings quite a few results, eg this around slide 46 seems to explain it well


I provide a general algorithm and an implementation in R to solve those kinds of problems in general: Financial Engineering: Static Replication of any Payoff Function. For your example: payoff <- data.frame(pi = c(0, 10, 30, 40, Inf), f_pi = c(30, 50, -10, 0, Inf)) payoff ## pi f_pi ## 1 0 30 ## 2 10 50 ## 3 30 -10 ## 4 40 0 ## 5 Inf Inf ...


Following further analysis, the results derived by Burgard and Kjaer rely on the assumption that the funding of the asset $S$ and the counterparty bond $P_C$ is fully achieved through the repo market, whereas funding for one's own bonds is unsecured. To make the derivation more rigorous, let us formally introduce into their model the following well-defined ...
