Assuming that the effects of interest capitalization are material, calculate the amount of interest costs to be capitalized by Matthew Corporation in 2020 in relation to the following separate events:

a.	On January 1, Matthew began construction for a new storage building for its own use. Expenditures incurred evenly throughout the year totaled $900,000. Matthew borrowed $1,100,000 specifically for construction of the storage building at an annual interest rate of 6.25%.
b.	Inventories costing $200,000 were routinely manufactured during the year. Matthew borrowed $200,000 at 8.25% to finance inventory-related costs.
c.	On September 1, Matthew began construction of a custom-designed machine to the specifications of a customer. As of December 31, $200,000 of materials, labor, and overhead have been assigned to the machine. Those costs were incurred evenly throughout the period September 1 through December 31. To finance construction, $240,000 was borrowed at a 9% interest rate.
