Answer:
Step-by-step explanation:
a)
The YTM of the bond at par value is equals to its coupon rate, 8.75%. Other things being equal, this 4% coupon rate bond will be more eye-catching as the coupon rate is lower than the current market yields, and its price is far below the call price. So, if yields drop, capital gains on the bond will not be restricted by the call price.
b)
If an investor foresees that yields will fall considerably, the 4% bond proposes a better expected return.
c)
Implicit call protection is offered in the sense that any likely fall in yields would not be nearly enough to make the firm consider calling the bond. In this sense, the call feature is almost irrelevant
