Answer:
1,006,400
Explanation:
To know the unamortized portion we have to solve for the amount amortizated at the first payment in December 31th,2021.
Under the effective-rate method we will calculate the amortization as follow:
interest expense:
9,080,000 x 8% = 726,400
cash outlay:
8,000,000 x 10% = 800,000
amortization on premium:
800,000 - 726,400 = 73,600
the unamortized bond premium at year-end should be:
1,080,000 - 73,600 = 1,006,400
