Brrrrr Problem Solution

Brrrrr Problem Solution Brrrrr Company manufactures two models of snowblowers: push and self-propelled. The company has manufactured the push model for years; the self-propelled model was introduced recently to tap a new segment of the market. While competitors charge quite a bit more for similar models, the selfpropelled model is extremely profitable for Brrrrr. Although sales of the self-propelled model have been increasing rapidly, the company’s profits have steadily declined. Management has become increasingly concerned about the accuracy of its costing system. The current cost accounting system allocates manufacturing overhead costs to the two products on the basis of direct labor hours. For 2006, the company has estimated that it will incur $3,570,000 in manufacturing support costs and produce 50,000 units of the push model and 10,000 units of the self-propelled model. The push model requires one hour of direct labor and the self-propelled model requires 2 hours. Direct labor costs $30 per DLH. The push model requires 1 machine hours and the self-propelled model requires 4 machine hours. Direct costs and selling prices per unit are as follows: Push Self-Propelled Direct Material $38 $54 Selling Price $145 $275 The company is considering switching to an ABC system. A recent cost study revealed the following activities and costs: Activity Annual Cost Engineering Design $440,000 Inspections $780,000 Production Set-ups $610,000 Scheduling $220,000 Material Handling $295,000 Machine Maintenance $450,000 Facility Costs $775,000 TOTAL $3,570,000 Solution The company schedules each production run. It doesn’t matter what type of product is being scheduled – they each take about the same amount of time. Material is pulled for each production run and is moved from workstation to workstation for each production run. The company has decided that facility-level costs should be allocated based on direct labor hours. They have calculated the following information related to activities: Activity Information Push Self-Propelled # of units per batch 500 100 Setup time per batch 0.5 hour 0.5 hour # of Inspections per batch 1 1 Inspection time per batch 0.5 hour 1.5 hour Engineering Design Hours 350 hours 650 hours

Requirements: a. Determine the plant-wide overhead rate using the current costing system. $3,570,000 of MOH costs 50,000 units of push model @ 1 DLH/unit = 50,000 DLH 10,000 units of self-propelled model @ 2 DLH/unit = 20,000 DLH Total DLH = 70,000 MOH Rate = $3,570,000 / 70,000 DLH = $51.00 per DLH b. Determine the gross margin (per unit) of the two models using the current costing system. Push: DM = $38 DL = $30/DLH * 1 DLH = $30 MOH = $51.00 * 1 DLH = $51 Total Product Cost = $119.00 Selling Price = $145 Gross Margin = $145 – $119 = $26 per unit Self-Propelled: DM = $54 DL = $30/DLH * 2 DLH = $60 MOH = $51 * 2 DLH = $102.00 Total Product Cost = $216.00 Selling Price = $275 Gross Margin = $275 – $216 = $59 per unit c. For each activity, calculate activity rates Activity Annual Cost Activity Driver Total Activity Rate Engineering Design $440,000 Engineering hrs 1,000 $440.00 Inspections $780,000 Inspection Hrs 200 $3,900.00 Production Set-ups $610,000 Setup time 200 $6,100.00 Scheduling $220,000 # of batches 200 $1,100.00 Material Handling $295,000 # of batches 200 $1,475.00 Machine Maintenance $450,000 MH 90,000 $5.00 Facility Costs $775,000 DLH 70,000 $11.07 d. Determine the gross margin (per unit) of the two models using the ABC information. NOTE: Your answers may differ slightly based on your rounding.
