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. Quarter Direct materials Direct labor Manufacturing overhead Total manufacturing costs (a) Number of units to be produced (b) Estimated unit product cost (a) + (b) First $ 240,000 160,000 220,000 $ 620,000 80,000 $ 7.75 Second $ 120,000 80,000 196,000 $ 396,000 40,000 $9.90 Third $ 60,000 40,000 184,000 $ 284,000 20,000 $ 14.20 Fourth $ 180,000 120,000 $? 60,000 $? 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 $0.60, 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.

Required information [The following information applies to the questions displayed below.] Delph Company uses job-order costing with a plantwide predetermined overhead rate based on machine-hours. At the beginning of the year, the company estimated that 54,000 machine-hours would be required for the period's estimated level of production. It also estimated $980,000 of fixed manufacturing overhead cost for the coming period and variable manufacturing overhead of $4.00 per machine-hour. Because Delph has two manufacturing departments-Molding and Fabrication-it is considering replacing its plantwide overhead rate with departmental rates that would also be based on machine-hours. The company gathered the following information to enable calculating departmental overhead rates: Machine-hours Fixed manufacturing overhead cost Variable manufacturing overhead cost per machine-hour Job D-70 Direct materials cost Direct labor cost Machine-hours Molding $ 370,000 $ 200,000 15,000 Job C-200 Direct…

Greenwood Company manufactures two products—14,000 units of Product Y and 6,000 units of Product Z. The company uses a plantwide overhead rate based on direct labor-hours. It is considering implementing an activity-based costing (ABC) system that allocates all of its manufacturing overhead to four cost pools. The following additional information is available for the company as a whole and for Products Y and Z:   Activity Cost Pool Activity Measure Estimated Overhead Cost Expected Activity Machining Machine-hours $ 192,000 10,000 MHs Machine setups Number of setups $ 50,400 120 setups Production design Number of products $ 76,000 2 products General factory Direct labor-hours $ 387,200 16,000 DLHs   Activity Measure Product Y Product Z Machining 7,200 2,800 Number of setups 50 70 Number of products 1 1 Direct labor-hours 7,200 8,800   What is the activity rate for the Product Design activity cost pool? What is the activity rate for the General Factory…

Shalom Company uses three activity pools to apply overhead to its products. Each activity has a cost driver used to allocate the overhead costs to the product. The activities and related overhead costs are as follows: product design P40,000; machining P300,000; and material handling P100,000. The cost drivers and estimated use are as follows: Activity Cost Pools Activities Product design Number of product changes Machining Machine hours Material handling Number of set-ups X Estimated Use of Cost Driver Per Activity Amounts must be in whole numbers. Example: 88,000 or (88,000) Unit costs be in whole numbers. Example: 88 Format of percentages: 88% Words must be in capital letters. 10 150,000 100 What is the activity-based overhead rate for material handling? J
