Dr. Prevost, wouldn’t these assumptions seem more relevant than the 10, 20, 30, 40..etc assumptions given by Bloomberg considering that CPR is suppose to level off at 6 over 30 months of the MBS? So far this MBS has paid constant prepayments of .2 why would they give such huge assumptions in comparison to the given data? I took the liberty of changing the CPR assumptions to something more realistic from my viewpoint.
