A few years ago, you purchased White Ltd Bond at a price of R9 120. The bond has a face value of R9 000 and it pays a coupon of 12% per-annum. The coupons are paid on the 30^th June and 30^th December every year. As of today, the bond is now left with 19 coupons to maturity and it is trading at a yield to maturity of 10%.

a) If you sell the bond today, how much will be your capital gain or loss? 

b) What is the possible driver of the capital gain/loss?
