Setup

The amortized book value uses the original nominal 8% yield, or 4% per half-year. The quoted 6% current yield would determine market value instead.

jbook=0.08/2=0.04j_{\mathrm{book}}=0.08/2=0.04

After coupon 20, ten coupons of 35 remain before the coupon steps to 45 for the final thirty periods.

B20=35a100.04+45v10a300.04+1,000v40B_{20}=35a_{\overline{10}|0.04}+45v^{10}a_{\overline{30}|0.04}+1{,}000v^{40}

Evaluate all remaining contractual payments on the book-yield curve.

B20=283.88+515.68+202.29=1,017.85B_{20}=283.88+515.68+202.29=1{,}017.85

Answer

Answer

The book value rounds to 1018, choice C.

B201,018(C)\boxed{B_{20}\approx1{,}018\quad\text{(C)}}
