The Zaf Radiator Company uses a normal-costing system with a single manufacturing overhead cost pool and machine-hours as the cost-allocation base. The following data are for 2020: (Click the icon to view the following data.) Read the requirements. 4,800,000 80,000 60 Requirement 2. Compute the under- or overallocated manufacturing overhead of Zaf Radiator in 2020. Begin by selecting the formula you will use. Next, enter the amounts in the formula and compute the under- or overallocated manufacturing overhead. (Use parentheses or a minus sign when entering overallocated amounts.) Manufacturing overhead Manufacturing overhead Manufacturing overhead incurred $ 4,900,000 allocated 4,500,000 =underallocated (overallocated) = $ 400,000 a. Adjust for this amount using a write-off to Cost of Goods Sold. Show the account balances after the write-off. Cost of Goods Sold Account Balance After Proration $ 8,400,000 Finished Goods Control Work-in-Process Control 1,250,000 750,000 b. Adjust for the amount using a proration based on ending balances (before proration) in Work-in-Process Control, Finished Goods Control, and Cost of Goods Sold. Begin by selecting the formula to calculate the adjustment to each account. Then enter the amounts in the formula. (Enter the proportions as a decimal to three decimal places, "X.XXX". Use a minus sign or parentheses to show overallocated amounts and adjustments to be subtracted.)

Compute the budgeted manufacturing overhead rate for 2020. 2. Compute the under- or overallocated manufacturing overhead of Zaf Radiator in 2020. Adjust for this amount using the following: a. Write-off to Cost of Goods Sold b. Proration based on ending balances (before proration) in Work-in-Process Control, Finished Goods Control, and Cost of Goods Sold c. Proration based on the overhead allocated in 2020 (before proration) in the ending balances of Work-in-Process Control, Finished Goods Control, and Cost of Goods Sold 3. Which method do you prefer in requirement 2? Explain.
