CFA Level 2 - Fixed Income Session 15-Reading 59 Valuing Mortgage-Backed and Asset-Backed Securit 4 (Practice Questions, Sample Questions) 1. Which of the following is a difference between agency and nonagency mortgage-backed securities (MBS) in the calculation of the cash flow yield? For nonagency MBSs: A) an assumption about default rates has to be made. (Explanation: Nonagency MBSs are not insured against default risk) B) the principal is variable. C) an assumption about the prepayment rate has to be made 2. Which of the following is a limitation of the cash flow yield measure? The cash flow yield measure: A) assumes that the projected cash flows are reinvested at the cash flow yield. (Explanation: Cash flow yield has two major deficiencies: (i) it is implicitly assumed that the cash flows will be reinvested at the cash flow yield prevailing when the MBS or ABS is priced, and (ii) it is assumed that the MBS or ABS will be held until maturity) B) assumes that interest rates do not change over the life of the security. C) assumes a flat yield curve 3. All of the following are limitations of the cash flow yield EXCEPT: A) the cash flow yield can never be as high as the comparable corporate bond yield due to prepayments. (Explanation: It assumes cash flows will be realized and the security will be held to maturity) B) it assumes cash flows will be realized. C) it is assumed that the MBS or ABS will be held to maturity 4. The assumption that the cash flows will be received is: A) more reasonable for a mortgage-backed security (MBS) or an asset-backed security (ABS) than for many other fixed-income securities. B) equally as reasonable for a mortgage-backed security(MBS) or an asset-backed security (ABS) than for many other fixed-income securities. C) less reasonable for a mortgage-backed security (MBS) or an asset-backed security (ABS) than for many other fixed-income securities (Explanation: The assumption that the cash flows will be received is less reasonable for an MBS or an ABS than for many other fixed-income securities because of prepayments) 5.

(Explanation: The discount rate that makes the price of a mortgage or asset-backed security equal to the present value of its cash flows is called the cash flow yield) C) asset-backed yield 7. Regarding the computation of the cash flow yield for an agency security, which of the following is the best reason why the assumption that the projected cash flows are actually realized is very restrictive? A) Interest rate risk. B) Default risk. C) Prepayments (Explanation: Prepayments instill uncertainty into the assumed cash flows used to compute cash flow yield)
