Ah Cheung is the portfolio manager for large pension fund and is considering investing $100 million to purchase the following 3 choices of ABC Ltd issued bonds:

ABC Bond A matures in 5 years and pays a 9%p.a. coupon on a $1,000 face value bond).

ABC Bond B matures in 10 years, pays an 8%p.a. coupon yield and is being offered at PAR.

ABC Bond C is a zero-coupon bond but will pay the face amount of $1,000 per bond at maturity in 10 years.

Note: All bonds pay coupon semi-annually and have market prices that imply a YTM of 8%p.a. Each of the 3 bonds is based on a $1,000 face value (par value) to be repayable at maturity.

(A) Without performing any calculations, can you roughly guess the price of the 3 bonds compared to PAR? (Hint: Observe the relationship between coupon and coupon.)

(B) Calculate each bond price?

(C) In the following table, it is the prices of the three bonds at 5% & 11% yield (YTM) comparing to their valuations when the required yield (YTM) was 8%p.a.:

YTM	ABC Bond A	ABC Bond B	ABC Bond C
5%	$1,175.04	$1,233.84	$610.27
11%	$924.62	$820.74	$342.73

Explain why each of these bonds has a different degree of sensitivity to a +/- 3% change in required yield (YTM). Give your reasoning in terms of volatility based on maturity and coupon effect.

(D) Calculate the duration of ABC Bond A, B, C?

(E) As an alternative, Ah Cheung has been invited to invest $1 million in a 10-year bond of a second firm, XYZ. XYZ bonds are similar in risk to ABC Bond B: they both pay 8%p.a. coupon for 10 years, but XYZ bonds pay coupon annually, not semi-annually as in the case of ABC. The XYZ bonds are priced 99% (or $990 per $1,000 face value).

What yield to maturity (YTM) is implied by the XYZ bond? Compare this yield to the 8%p.a. of the ABC semi-annual coupon bond (Bond B) above. In which bond should Ah Cheung invest?
