Pleаse use the fоllоwing аdditiоnаl information for Questions 38-41: A financial institution originates a pool of 500 30-year mortgages, each averaging $150,000 with an annual mortgage coupon rate of 8 percent. Assume that the entire mortgage portfolio is securitized to be sold as GNMA pass-throughs. The GNMA credit risk insurance fee is 6 basis points and that the FI's servicing fee is 19 basis points. Question: What is the present value of the mortgage pool? 

Pleаse use the fоllоwing аdditiоnаl information for Questions 34-37: Suppose there are three bond ratings: A, B, C and default (D). The ratings-migration probabilities over the next year look like this for a B-rated, 3-year, 4% annual-coupon bond ($100 par value) loan: Rating in 1 year          Probability A                                 0.03 B                                 0.92 C                                 0.03 Default                        0.02 The yield on A rated bonds is 5%; the yield on B rated bonds is 6%; and the yield on a C rated bond is 9%. All term structures are flat (i.e. forward rates equal spot rates). Assume that in default you recover 50% at the time of default. Question: Using the values and probabilities at the end of the year, compute the mean value.
