Since teams generally have 4 or 5 members, the team solution will likely end about
here. The remainder of the table is shown for help in answering part 3.

*Discrepancy due to rounding.
The following computations should be articulated by team members as
each line is explained and prepared:
Column (B) Bond interest expense = Bonds’ prior period carrying value x
Column (C) Premium Amortization = difference between cash interest paid and
bond interest expense, or [(A) – (B)].
Column (D) Unamortized Premium = prior period’s unamortized premium less
the current period’s premium amortization, or [(D) – (C)].
Column (E) Bonds’ Carrying Value = Bonds’ par value plus unamortized
premium, or [$100,000 + (D)] or Previous book value – Period’s amortization.
