Wells Fargo issues a CMBS. The mortgage pool consists of interest only loans, with a total loan amount of $15 million. Assume the mortgage rate in the pool is 11%, the mortgages are annually compounded, and the loan maturity is 4 years. There are three tranches in the CMBS: 1. Tranche A, with an amount of $10 million at 8% coupon rate, 2. Tranche B, $3 million at 10% coupon rate, 3. the residual tranche, with $2 million. The maturity of the MBS is 4 years. Suppose some loans are in default, so only 70% of the original loan amount can be recovered at the end of 4th year. However, the mortgage pool can still generate the same amount of cash flow available in year 4 as those in the first 3 years . What is the investor return for Tranche B for the 4 year period?

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
