How to solve this Bond Valuation question

Setup

Setup

A coupon rate above yield makes the bond a premium instrument, so postponing redemption preserves more above-market coupons.

c=10%>i=5%earliest call is limitingc=10\%>i=5\%\Longrightarrow\text{earliest call is limiting}

Model

Model

For the buyer's guaranteed yield, the least valuable permitted outcome is therefore the earliest call date.

P=100a160.05+1000v16P=100a_{\overline{16}|\,0.05}+1000v^{16}

Compute

Compute

Discounting 16 coupons of 100 and the 1,000 call payment at 5% gives approximately 1,542.

P=100(10.0378)+458.11=1542P=100(10.0378)+458.11=1542

Answer

Answer

That is the maximum safe purchase price, corresponding to choice B.

Pmax=1542(B)\boxed{P_{\max}=1542\quad\text{(B)}}
