Process Costing for a Service Company Madison Electric Company uses a fossil fuel (coal) plant for generating electricity. The facility can generate 900 megawatts (million watts) per hour. The plant operates 600 hours during March. Electricity is used as it is generated; thus, there are no inventories at the beginning or end of the period. The March conversion and fuel costs are as follows: Conversion costs Fuel Total $40,500,000 10,800,000 $51,300,000 Madison also has a wind farm that can generate 100 megawatts per hour.

Remarkable Enterprises requires four units of part A for every unit of Al that it produces. Currently, part A is made by Remarkable, with these per-unit costs in a month when 4,000 units were produced: Variable manufacturing overhead is applied at $1.60 per unit. The other $0.50 of overhead consists of allocated fixed costs. Remarkable will need 8,000 units of part A for the next years production. Altoona Corporation has offered to supply 8,000 units of part A at a price of $8.00 per unit. If Remarkable accepts the offer, all of the variable costs and $2,000 of the fixed costs will be avoided. Should Remarkable accept the offer from Altoona Corporation?
Step Costs, Relevant Range Bellati Inc. produces large industrial machinery. Bellati has a machining department and a group of direct laborers called machinists. Each machinist can machine up to 500 units per year. Bellati also hires supervisors to develop machine specification plans and oversee production within the machining department. Given the planning and supervisory work, a supervisor can oversee, at most, three machinists. Bellatis accounting and production history shows the following relationships between number of units produced and the annual costs of supervision and materials handling (by machinists): Required: 1. Prepare a graph that illustrates the relationship between direct labor cost and number of units produced in the machining department. (Let cost of direct labor be the vertical axis and number of units be the horizontal axis.) Would you classify this cost as a strictly variable cost, a fixed cost, or a step cost? 2. Prepare a graph that illustrates the relationship between the cost of supervision and the number of units produced. (Let cost of supervision be the vertical axis and number of units be the horizontal axis.) Would you classify this cost as a strictly variable cost, a fixed cost, or a step cost? 3. Suppose that the normal range of production is between 1,400 and 1,500 units and that the exact number of machinists is currently hired to support this level of activity. Further suppose that production for the next year is expected to increase by an additional 500 units. What is the increase in the cost of direct labor? Cost of supervision?
The Lubbock plant of Morrils Small Motor Division produces a major subassembly for a 6.0 horsepower motor for lawnmowers. The plant uses a standard costing system for production costing and control. The standard cost sheet for the subassembly follows: During the year, the Lubbock plant had the following actual production activity: a. Production of subassemblies totaled 50,000 units. b. A total of 260,000 pounds of raw materials was purchased at 4.70 per pound. c. There were 60,000 pounds of raw materials in beginning inventory (carried at 5 per lb.) There was no ending inventory. d. The company used 82,000 direct labor hours at a total cost of 1,066,000. The Lubbock plants practical activity is 60,000 units per year. Standard overhead rates are computed based on practical activity measured in standard direct labor hours. Required: 1. CONCEPTUAL CONNECTION Compute the materials price and usage variances. Of the two materials variances, which is viewed as the more controllable? To whom would you assign responsibility for the usage variance in this case? Explain. 2. CONCEPTUAL CONNECTION Compute the labor rate and efficiency variances. Who is usually responsible for the labor efficiency variance? What are some possible causes for this variance? 3. CONCEPTUAL CONNECTION Assume that the purchasing agent for the small motors plant purchased a lower-quality raw material from a new supplier. Would you recommend that the plant continue to use this cheaper raw material? If so, what standards would likely need revision to reflect this decision? Assume that the end products quality is not significantly affected. 4. Prepare all possible journal entries.
Vexar manufactures nails. Manufacturing is a one-step process where the nails are forged. This is the information related to this years production: Â Ending inventory was 100% complete as to materials and 70% complete as to conversion, and the total materials cost is $115,080 and the total conversion cost is $72,072. Using the weighted-average method, what are the unit costs if the company transferred out 34,000 units? Using the weighted-average method, prepare the companys process cost summary for the month.
Identify cost graphs The following cost graphs illustrate various types of cost behavior: For each of the following costs, identify the cost graph that best illustrates its cost behavior as the number of units produced increases: A. Total direct materials cost B. Electricity costs of 1,000 per month plus 0.10 per kilowatt-hour C. Per-unit cost of straight-line depreciation on factory equipment D. Salary of quality control supervisor, 20,000 per month E. Per-unit direct labor cost
Bolger and Co. manufactures large gaskets for the turbine industry. Bolgers per-unit sales price and variable costs for the current year are as follows: Bolgers total fixed costs aggregate to 360,000. Bolgers labor agreement is expiring at the end of the year, and management is concerned about the effects of a new labor agreement on its break-even point in units. The controller performed a sensitivity analysis to ascertain the estimated effect of a 10-per-unit direct labor increase and a 10,000 reduction in fixed costs. Based on these data, the break-even point would: a. decrease by 1,000 units. b. decrease by 125 units. c. increase by 375 units. d. increase by 500 units.

Preparation of Income Statement: Manufacturing Firm Laworld Inc. manufactures small camping tents. Last year, 200,000 tents were made and sold for 60 each. Each tent includes the following costs: The only selling expenses were a commission of 2 per unit sold and advertising totaling 100,000. Administrative expenses, all fixed, equaled 300,000. There were no beginning or ending finished goods inventories. There were no beginning or ending work-in-process inventories. Required: 1. Calculate the product cost for one tent. Calculate the total product cost for last year. 2. CONCEPTUAL CONNECTION Prepare an income statement for external users. Did you need to prepare a supporting statement of cost of goods manufactured? Explain. 3. CONCEPTUAL CONNECTION Suppose 200,000 tents were produced (and 200,000 sold) but that the company had a beginning finished goods inventory of 10,000 tents produced in the prior year at 40 per unit. The company follows a first-in, first-out policy for its inventory (meaning that the units produced first are sold first for purposes of cost flow). What effect does this have on the income statement? Show the new statement.
During the week of June 12, Harrison Manufacturing produced and shipped 15,000 units of its aluminum wheels: 3,000 units of Model A and 12,000 units of Model B. The following costs were incurred: Required: 1. Assume initially that the value-stream costs and total units shipped apply only to one model (a single-product value stream). Calculate the unit cost, and comment on its accuracy. 2. Calculate the unit cost for Models A and B, and comment on its accuracy. Explain the rationale for using units shipped instead of units produced in the calculation. 3. What if Model A is responsible for 40 percent of the materials cost? Show how the unit cost would be adjusted for this condition.
