Why after? Why not before repayment? |

Serial bonds are sold with staggered maturities, so imagine you have to pay interest on all bonds plus par for the first one before the maturity of the first bond, then for the next payment the interest will be lower because you're paying interest on fewer bonds. |

after the prepayments, the sum principal owed decreases which then decreases the amount we apply the rate to find the coupon payment. |
