Which type of serial bond features total principal repayable in equal installments over a specified time?

The correct option refers to a type of serial bond where total principal is repaid in equal installments over a specified time frame. In the context of governmental accounting and financial reporting, serial bonds typically have a predetermined repayment schedule that allows for regular and systematic payments.

These bonds are structured so that the borrower pays off a portion of the principal along with interest at each payment interval. This repayment structure provides a clear and manageable way for governments to service their debt obligations over time, making it easier to budget for these payments.

In contrast, other types of bonds may not offer the same systematic principal repayment schedule. For instance, deferred bonds typically involve payments that start at a future date, annuity bonds provide payments that can vary, and irregular bonds may have less predictable payment structures. By providing equal principal installments, the responsible management of cash flows and budgeting becomes more straightforward for the issuing government.
