A city issues a serial bond to fund the construction of a new public library. The bond is structured to mature in increments over a 20-year period, with a portion of the principal being repaid each year. This allows the city to manage its debt repayment gradually without a significant financial burden at any single point.
The finance director explained that using a serial bond would enable the city to finance the new road infrastructure without imposing a heavy debt load in any single year.
