Final answer:
The journal entries to record the issuance of the bonds, payment of interest and related amortization on July 1, 2025, and accrual of interest and related amortization on December 31, 2025.
Step-by-step explanation:
a. The journal entry to record the issuance of the bonds would be:
Debit: Cash ($420,000 × 102%) = $428,400
Credit: Bonds Payable = $420,000
Credit: Premium on Bonds Payable ($428,400 - $420,000) = $8,400
b. The journal entry to record the payment of interest and related amortization on July 1, 2025, would be:
Debit: Interest Expense ($420,000 × 10% × rac{1}{2}) = $21,000
Debit: Premium on Bonds Payable ($420,000 × 2.7068750 × rac{1}{2}) = $569.902083
Credit: Cash = $21,569.902083
c. The journal entry to record the accrual of interest and the related amortization on December 31, 2025, would be:
Debit: Interest Expense ($420,000 × 10% × rac{1}{2}) = $21,000
Debit: Premium on Bonds Payable ($420,000 × 2.4912214 × rac{1}{2}) = $522.321223
Credit: Cash = $21,522.321223
