Kingsport Containers Company makes a single product that is subject to wide seasonal variations in demand. The company uses a job-order costing system and computes plantwide predetermined overhead rates on a quarterly basis using the number of units to be produced as the allocation base. Its estimated costs, by quarter, for the coming year are given below. Direct materials Direct labor Manufacturing overhead Total manufacturing costs (a) Number of units to be produced (b) Estimated unit product cost (a) (b) Quarter Third $ 50,000 Fourth $150,000 60,000 $7 First $ 200,000 80,000. 230,000 $.510,000 Second $ 100,000 40,000 206,000 $ 346,000 160,000 $ 3.19 80,000 $4.33 20,000 194,000 $264,000 40,000 $ 6.60 120,000 $7 Management finds the variation in quarterly unit product costs to be confusing. It has been suggested that the problem lies with manufacturing overhead because it is the largest element of total manufacturing cost. Accordingly, you have been asked to find a more appropriate way of assigning manufacturing overhead cost to units of product. Required: 1. Assuming the estimated variable manufacturing overhead cost per unit is $0.30, what must be the estimated total fixed manufacturing overhead cost per quarter? 2. Assuming the assumptions about cost behavior from the first three quarters hold constant, what is the estimated unit product cost for the fourth quarter? 3. What is causing the estimated unit product cost to fluctuate from one quarter to the next? 4. Assuming the company computes one predetermined overhead rate for the year rather than computing quarterly overhead rates. calculate the unit product cost for all units produced during the year. Required 1 Required 2 Required 3 Required 4 Assuming the estimated variable manufacturing overhead cost per unit is $0.30, what must be the estimated total fixed manufacturing overhead cost per quarter? Fixed manufacturing overhead cost Required 1 Required 2 Required 3 Required 4 Assuming the assumptions about cost behavior from the first three quarters hold coristant, what is the estimated unit product cost for the fourth quarter? Note: Do not round intermediate calculations and round the "Unit product cost" to 2 decimal places. Unit product cost Required 1 Required 2 Required 3 Required 4 What is causing the estimated unit product cost to fluctuate from one quarter to the next? The fixed portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The unit product cost increases as the level of production decreases because the fixed overhead is spread over fewer units The fixed portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The unit product cost decreases as the level of production decreases because the fixed overhead is spread over fewer units The variable portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The unit product cost increases as the level of production decreases because the variable overhead is spread over fewer units The variable portion of the manufacturing overhead cost is causing the unit product costs to fluctuate. The unit product cost decreases as the level of production decreases because the variable overhead is spread over fewer units Required 1 Required 2 Required 3 Required 4 Assuming the company computes one predetermined overhead rate for the year rather than computing quarterly overhead rates, calculate the unit product cost for all units produced during the year, Note: Do not round intermediate calculations and round your final answer to 2 decimal places.
