Step-by-step explanation:
Arlington Company
Schedule of Weighted-Average accumulated expenditure
Date Amount Current year Weighted Average
capitalization Accumulated
period Expenditures
1-Mar $6,400,000 10/12 $5,333,333
1-Jun $5,280,000 7/12 $3,080,000
31-Dec $8,000,000 0/12 $0
Total $19,680,000. $8,413,333
Note: Weighted-Average accumulated expenditure = Amount * Current year capitalization period
Weighted average interest rate on general borrowings = 10% * (6,400,000 / 18,400,000) + 11%* (12,000,000 / 18,400,000)
=10.65%
Interest for specific borrowing should be capitalized for entire year.
Avoidable interest = ($3,200,000*12%) + ($8,413,333 - $3,200,000) * 10.65%
Avoidable interest = $939,220
