Suppose that there are two bonds (Bond A and Bond B) with the same hazard rate ), so their marginal default time cdfs are Fi(t) = 1 - exp(- t), i = 1, 2, where t > 0 and > 0. Their default times are bound together ) by a copula function as specified below. Our credit analysts tell us there is a 95% chance that neither bond defaults in the first 2 years (i.e. when t 0 and > 0. Their default times are bound together ) by a copula function as specified below. Our credit analysts tell us there is a 95% chance that neither bond defaults in the first 2 years (i.e. when t
