Answer: $40,000
Step-by-step explanation:
When capitalizing Interest for a PPE, accounting procedure is that one looks at the actual interests incurred vs the interest computed on the weighted-average amount of accumulated expenditures for the PPE and then pick the lower of the two for capitalization.
The actual interest incurred is;
= 50,000 + 20,000
= $70,000
The Interest computed on the weighted-average amount of accumulated expenditures for the building during 20X3 = $40,000. This is the lower one and so will be the amount capitalized.
