The bond is purchased at a premium relative to its call amount.

1321>1111nworst=181321>1111\Longrightarrow n_{\mathrm{worst}}=18

Model

Model

For a premium bond, the earliest return of redemption amortizes the premium fastest and produces the lowest yield.

1321=111.10a18i+1111(1+i)181321=111.10a_{\overline{18}|\,i}+1111(1+i)^{-18}

Compute

Solve the annual yield from eighteen coupons followed by the call payment.

i=0.07985i=0.07985

Answer

Answer

The minimum possible annual effective yield is 7.985%, corresponding to choice C.

imin=7.985%(C)\boxed{i_{\min}=7.985\%\quad\text{(C)}}
