Arlington Company is constructing a building. Construction began on January 1 and was completed on December 31. Expenditures were $6,400,000 on March 1, $5,280,000 on June 1, and $8,000,000 on December 31. Arlington Company borrowed $3,200,000 on MARCH 1 on a 5- year, 12% note to help finance construction of the building. In addition, the company had outstanding all year a 10%, 3-year, $6,400,000 note payable and an 11%, 4-year, $12,000,000 note payable.

When calculating avoidable interest do we multiply by 10/12 for the construction note since it was not for an entire year because it was borrowed on march?
