Answer:
A) Coupon rate %
coupon rate = coupon / par value = $60 / $1,000 = 0.06 = 6%
B) Current yield %
current yield = coupon / bond's market price = $60 / $880 = 0.06818 = 6.82%
C) Approximate yield to maturity %
Approximate YTM = {coupon + [(face value - market value)/n] / [(face value + market value)/2] = {60 + [(1,000 - 880)/8] / [(1,000 + 880)/2] = 75 / 940 = 0.07978 x 100 = 7.98%
D) Exact yield to maturity = 8.096%
I used a financial calculator to determine the exact YTM, but you can also do it by solving the following equation:
Price = [coupon / (1 + r)] + [coupon / (1 + r)²] + [coupon / (1 + r)³] + [coupon / (1 + r)⁴] + [coupon / (1 + r)⁵] + [coupon / (1 + r)⁶] + [coupon / (1 + r)⁷] + [(coupon + face value) / (1 + r)⁸]
880 = [60 / (1 + r)] + [60 / (1 + r)²] + [60 / (1 + r)³] + [60 / (1 + r)⁴] + [60 / (1 + r)⁵] + [60 / (1 + r)⁶] + [60 / (1 + r)⁷] + [1,060 / (1 + r)⁸]
