 CASE 1: CASES FOR MANAGEMENT DECISION MAKING 1. Define and explain the meaning of a predetermined manufacturing overhead rate that is applied in a job-order costing system. This is the estimate of how much overhead will be needed based on estimate of production. 2. What are the advantages and disadvantages of using the cost of each print as a manufacturing overhead cost driver? Advantage: Costs will be more accurate, costs are tailored more too specific products. Disadvantage:

Relies too heavily on prediction of how many of each particular product will be sold. 3. Using the information on the next page, compute and interpret the predetermined manufacturing overhead rate for Wall Decor. Total cost = number of prints x cost per print Unframed Print 80,000 x \$12 = \$960,000 Steel Framed Print, No Matting15,000 x \$16 = \$240,000 Wood Framed Print, with Matting7,000 x \$20 = \$140,000 Total Cost of Prints = \$960,000 + \$240,000 + \$140,000 = \$1,340,000

Predetermined Manufacturing Overhead Rate = (Manufacturing overhead/total cost of prints) x 100% = (375,200/1,340,000) x 100% = 28% 4. Compute the product cost for the following three items. a)Lance Armstrong unframed print (base of print \$12) b)John Elway print in steel frame, no mat (base cost of print \$16) c)Lambeau Field print in wood frame with mat (base cost of print \$20) Direct Materials = print + frame & glass + matting

Direct Labor = picking labor + framing & matting labor Manufacturing Overhead = direct materials x predetermined rate Cost of Prints = direct materials + direct labor + manufacturing overhead Picking labor = (rate/hour) x minutes worker = (rate/ 60min) x minutes worked = (\$12/60) x 10 = \$2/unit For Steel Framed, Matting & Framing Time = (rate/ 60min) x minutes worked = (\$21/60) x 20 = \$7/unit For Wood Framed, Matting & Framing Time = (rate/ 60min) x minutes worked = (\$21/60) x 30 = \$10. 50/unit

Direct Materials(\$) Direct Labor(\$) Manufacturing Overhead (\$) Total Product Cost(\$) Unframed Prints 12 2 (12 x 0. 28) = 3. 36 17. 36 Steel Framed, No Matting(16 + 4) = 20 (2 + 7) = 9 (16 x 0. 28) = 4. 48 33. 48 Wood Framed, with Matting(20 + 6 + 4) = 30 (2 x 10. 50) = 12. 50 (20 x 0. 28) = 5. 60 48. 10 5. a) How much of the total overhead cost is expected to be allocated to unframed prints? ) How much of the total overhead cost is expected to be allocated to steel framed prints? c) How much of the total overhead cost is expected to be allocated to wood framed prints? d) What percentage of the total overhead cost is expected to be allocated to unframed prints? Total Overhead Cost = Manufacturing Overhead x number of units expected Total Overhead Cost Unframed Prints \$3. 36 x 80,000 = \$268,800 Steel Framed, No Matting \$4. 48 x 15,000 = \$67,200 Wood Framed, with Matting \$5. 60 x 7,000 = \$39,200
