Calculates tranche spread for CDO using technique described in Appendix A of paper
Valuation of a CDO and an nth to Default CDS Without Monte Carlo Simulation Formulas for CDO legs valuation are based on
CDO Lecture notesResults are not a perfect match to the values metnioned in Table 7 of Hull's paper, but somewhat near. Don't know if it is because numerical approximation error or a bug.If someone has suggestion please do discuss below.
eg., following are values obtained by running this program:
2273 1487
455 474
91 204
following are corresponding values mentioned in table 7:
2279 1487
450 472
89 203
