3. 2009 Foster School of Business Cost Accounting L.DuCharme 3 Overview—Process Costing When to use Accounting issue Equivalent Units (EUs) Mechanics of process costing –w/o TI costs –with TI costs Accounting for Spoilage (chapter 18)

4. 2009 Foster School of Business Cost Accounting L.DuCharme 4 When is it appropriate to use process costing? Or what companies use process costing? Which companies would not use process costing?

6. 2009 Foster School of Business Cost Accounting L.DuCharme 6 What is the BIG accounting issue? The task is to divide the total costs in WIP between ending WIP and inventory completed and transferred out (CTO). This is no big deal until you consider that E.WIP is partially completed and CTO by definition is 100% complete (for each step of production)! What do we do?

7. 2009 Foster School of Business Cost Accounting L.DuCharme 7 Equivalent Units 15 half-time (50%) professors is equivalent to 7.5 full-time professors. Often for people we refer to FTEs. 100 teddy bears that are (on average) 45% complete are equivalent to 45 completed bears = 45 equivalent units.

8. 2009 Foster School of Business Cost Accounting L.DuCharme 8 EU—when to use Not all organizations that use process costing have to calculate EUs! You only have to calculate/use EUs when ending WIP inventories are material. –No (or little) ending WIP—what companies? –Material ending WIP—what companies?

9. 2009 Foster School of Business Cost Accounting L.DuCharme 9 Assumed flow of costs Process costing is combined with the assumed flow of costs: –Standard cost –Weighted average (we will focus on this) –FIFO (least used)

10. 2009 Foster School of Business Cost Accounting L.DuCharme 10 Three Equations/steps At the core of calculations are 3 equations: –Physical unit calculations (in units)— B.WIP + units started this period = CTO + E.WIP –EU calculations (in EU)— B.WIP + work done this period = CTO + E.WIP –Costs (in $)— B.WIP + period’s costs = CTO + E.WIP

11. 2009 Foster School of Business Cost Accounting L.DuCharme 11 Timing of added costs Whenever a factor of production is added at a different time (beginning, middle, end, etc.) in production, a separate EU computation is required (for that factor)! For example if DM is added at a different time than CC, each has to have a separate EU calculation (see example in class)

12. 2009 Foster School of Business Cost Accounting L.DuCharme 12 Transferred –In Costs CTO from one department is TI to the next department. TI does not equal direct materials.

13. 2009 Foster School of Business Cost Accounting L.DuCharme 13 The BIG Picture The goal is to assign costs to CTO units. In order to do this you need costs per unit. (1)When costs change from period to period, you have to make a cost-flow assumption. (2) When incomplete units are present in E.WIP, you have to adjust via EU calculations.

23. 2009 Foster School of Business Cost Accounting L.DuCharme 23 Chapter 18 This chapter focuses on accounting for Spoilage (flip side of product quality). You are responsible for the first 3 pages of the chapter and what is covered in class.

24. 2009 Foster School of Business Cost Accounting L.DuCharme 24 Terminology Spoilage –Unacceptable product discarded or sold for disposal value (e.g., “Seconds”). Reworked units –Unacceptable product that is reworked and sold as good product. Scrap—material left over with min. or zero sales value. Waste—can be toxic and very costly to dispose of.

25. 2009 Foster School of Business Cost Accounting L.DuCharme 25 Goal of most operations Reduction of S/R/S/W –Consistent with increased quality –R&D and design play key roles in reducing S/R/S/W.

26. 2009 Foster School of Business Cost Accounting L.DuCharme 26 “Types” of spoilage Normal spoilage –Expected spoilage with efficient operations. (“normal spoilage rates” = units of normal spoilage / total good units) Abnormal spoilage –Unexpected (greater than expected) spoilage under efficient operations. Considered avoidable & controllable. Some companies treat all spoilage as abnormal!

27. 2009 Foster School of Business Cost Accounting L.DuCharme 27 Why do we care? Because we account for the two types differently!! Abnormal spoilage is expensed in the period it is discovered. Normal spoilage is added to job cost, or under process costing added equally to all units passing the inspection point.
