Question

Gary Stevens and Mary James are production managers in the Consumer Electronics Division of General Electronics Company, which has several dozen plants scattered in locations throughout the world. Mary manages the plant located in Des Moines, Iowa, while Gary manages the plant in El Segundo, California. Production managers are paid a salary and get an additional bonus equal to 10% of their base salary if the entire division meets or exceeds its target profits for the year. The bonus is determined in March after the company’s annual report has been prepared and issued to stockholders. Shortly after the beginning of the new year, Mary received a phone call from Gary that went like this: Gary: How’s it going, Mary? Mary: Fine, Gary. How’s it going with you? Gary: Great! I just got the preliminary profit figures for the division for last year and we are within $53,000 of making the year’s target profits. All we have to do is pull a few strings, and we’ll be over the top! Mary: What do you mean? Gary: Well, one thing that would be easy to change is your estimate of the percentage completion of your ending work in process inventories. Mary: I don’t know if I can do that, Gary. Those percentage completion figures are supplied by Tom Winthrop, my lead supervisor, who I have always trusted to provide us with good estimates. Besides, I have already sent the percentage completion figures to corporate headquarters. Gary: You can always tell them there was a mistake. Think about it, Mary. All of us managers are doing as much as we can to pull this bonus out of the hat. You may not want the bonus check, but the rest of us sure could use it. The final processing department in Mary’s production facility began the year with no work in process inventory. During the year, 290,000 units were transferred in from the prior processing department and 265,000 units were completed and sold. Costs transferred in from the prior department totaled $53,070,000. No materials are added in the final processing department. A total of $21,428,750 of conversion cost was incurred in the final processing department during the year. Required: 1. Tom Winthrop estimated that the units in ending work in process inventory in the final processing department were 25% complete with respect to the conversion costs of the final processing department. If this estimate of the percentage completion is used, what would be the cost of goods sold for the year? 2. Does Gary Stevens want the estimated percentage completion to be increased or decreased? 3. What percentage completion would result in increasing reported net operating income by $53,000 over the net operating income that would be reported if the 25% figure were used?

Answer 1

1) Per unit cost received from prior department = $53070000 / 290000 = $183 per unit

Per unit cost of conversion cost added this year = 21428750 / 271250 ie.(265000 + 25000*25%) = $79

COGS = 265000 * ( $183 + 79) = $69430000

2) Wants to decrease the percentage because it leaves less conversion costs to closing WIP and more towards Completed and sold units.

3) Percentage of completion to be reported to have increase in the reported NOI by $53000 :

Per unit increase in NOI = $53000 / 265000 = $0.20 per unit

Conversion cost of the year towards the completed units = $79.20 * 265000 = $20988000

Conversion cost of the year towards the Closing WIP units = $21428750 - $20988000 = $$440750

Completed units of closing WIP = $440750 / 79.20 = 5565 UNITS

Thus, Percentage of completion to be reported to have increase in the reported NOI by $53000 = 5565/25000 = 22.26%
