 Study Session 16-63-e, i
 Compute, compare, and contrast the various yield spread measures.
 Compute the after-tax yield of a taxable security and the tax-equivalent yield of a tax-exempt security.
 Yield ratio = (yield on tax-exempt bond) / (yield of US Treasury) = 3.86 / (3.86 + 100bp) = 3.86 / 4.86 = 0.79

| B | 94.356 | $5 million | 7.70 |  
| C | 88.688 | $3 million | 11.55 |  
 A. 5.55 years.
 B. 5.76 years.
 C. 6.82 years.
 
 Answer: A
 “Introduction to the Measurement of the Interest Rate Risk,” Frank J. Fabozzi
 2009 Modular Level I, Volume 5, pp. 468
 Study Session 16-66-f
 Compute the duration of a portfolio, given the duration of the bonds comprising the portfolio, and explain the limitations of portfolio duration.
 Portfolio value = (1.02 × 7 mil) + (0.94356 × 5 mil) + (0.88688 × 3 mil) =14,518,440
 Weight, Bond A = 7,140,000 / 14,518,440 = 0.492
 Weight, Bond B = 4,717,800 / 14,518,440 = 0.325
 Weight, Bond C = 2,660,640 / 14,518,440 = 0.183
 Portfolio duration = (0.492 × 1.89) + (0.325 × 7.70) + (0.183 × 11.55) = 5.55
