Answer:
The company will first determinate the capitalize expenditures.
Then, subtrac the specifit borrowing
and use a weighted average rate of 10.42% for the amount of capitalized expenditures above the especific borrowings.
Adding the specfit borowing interest and the interest from the average rate we will get the avoidable interest.
Explanation:
The company will avoind interest for the amount of specific borrowing:
especific borrowings
$4,400,000 at 12% annual rate 528,000.00
And then, calculate the average rate of their outstanding debt
average rate
principal rate interest
3,080,000 0.1 308000
2,200,000 0.11 242000
5,280,000 550000
total interest / total principal 0.104166667
and use that rate for the amount of capitalized expenditures above the especific borrowings.
