Fundamentals of Cost Accounting
- Cost-Based Pricing Otero Fibers, Inc., specializes in the manufacture of synthetic fibers that the company uses in many products such as blankets, coats, and uniforms for police and firefighters. Otero has been in business since 1985 and has been profitable every year since 1993. The company uses a standard cost system and applies overhead on the basis of direct labor hours. Otero has recently received a request to bid on the manufacture of 800,000 blankets scheduled for delivery to several military bases. The bid must be stated at full cost per unit plus a return on full cost of no more than 10 percent after income taxes. Full cost has been defined as including all variable costs of manufacturing the product, a reasonable amount of fixed overhead, and reasonable incremental administrative costs associated with the manufacture and sale of the product. The contractor has indicated that bids in excess of $30 per blanket are not likely to be considered. In order to prepare the bid for the…arrow_forwardDura-Conduit Corporation manufactures plastic conduit that is used in the cable industry. A conduit is a tube that encircles and protects the underground cable. In the process for making the plastic conduit, called extrusion, the melted plastic (resin) is pressed through a die to form a tube. Scrap is produced in this process. Information from the cost of production reports for three months is as follows, assuming that inventory remains constant: Assume that there is one-half pound of resin per foot of the finished product. a. Determine the resin materials cost per foot of finished product for each month. Round to the nearest whole cent. b. Determine the ratio of the number of resin pounds output in conduit by the number of pounds input into the process for each month. Round percentages to one decimal place. c. Interpret the resin materials cost per foot for the three months. Use the information in (a) and (b) to explain what is happening. d.

The price and cost of goods sold for each unit are as follows: In addition, the company incurs selling and administrative expenses of 226,250. The company wishes to assign these costs to its three major customers, Gough Industries, Breen Inc., and The Martin Group. These expenses are related to three major nonmanufacturing activities: customer service, project bidding, and engineering support. The engineering support is in the form of engineering changes that are placed by the customer to change the design of a product. The budgeted activity costs and activity bases associated with these activities are: Activity-base usage and unit volume information for the three customers is as follows: Instructions 1. Determine the activity rates for each of the three nonmanufacturing activity pools. 2. Determine the activity costs allocated to the three customers, using the activity rates in (1). 3. Construct customer profitability reports for the three customers, dated for the year ended December 31, using the activity costs in (2). The reports should disclose the gross profit and operating income associated with each customer. 4. Provide recommendations to management, based on the profitability reports in (3).arrow_forward
- Otero Fibers, Inc., specializes in the manufacture of synthetic fibers that the company uses in many products such as blankets, coats, and uniforms for police and firefighters. Otero has been in business since 1985 and has been profitable every year since 1993. The company uses a standard cost system and applies overhead on the basis of direct labor hours. Otero has recently received a request to bid on the manufacture of 800,000 blankets scheduled for delivery to several military bases. The bid must be stated at full cost per unit plus a return on full cost of no more than 10 percent after income taxes. Full cost has been defined as including all variable costs of manufacturing the product, a reasonable amount of fixed overhead, and reasonable incremental administrative costs associated with the manufacture and sale of the product. The contractor has indicated that bids in excess of 30 per blanket are not likely to be considered. In order to prepare the bid for the 800,000 blankets, Andrea Lightner, cost accountant, has gathered the following information about the costs associated with the production of the blankets. Direct machine costs consist of items such as special lubricants, replacement of needles used in stitching, and maintenance costs. These costs are not included in the normal overhead rates. Otero recently developed a new blanket fiber at a cost of 750,000. In an effort to recover this cost, Otero has instituted a policy of adding a 0.50 fee to the cost of each blanket using the new fiber. To date, the company has recovered 125,000. Lightner knows that this fee does not fit within the definition of full cost, as it is not a cost of manufacturing the product. Required: 1. Calculate the minimum price per blanket that Otero Fibers could bid without reducing the companys operating income. 2. Using the full-cost criteria and the maximum allowable return specified, calculate Otero Fibers bid price per blanket. 3. Without prejudice to your answer to Requirement 2, assume that the price per blanket that Otero Fibers calculated using the cost-plus criteria specified is greater than the maximum bid of 30 per blanket allowed. Discuss the factors that Otero Fibers should consider before deciding whether or not to submit a bid at the maximum acceptable price of 30 per blanket.

Although the vehicles vary, the maintenance services provided follow a fairly standard pattern. Recently, a potential customer has approached the company, requesting a new maintenance service for a radically different type of vehicle. New servicing equipment and some new labor skills will be needed to provide the maintenance service. The customer is placing an initial order to service 150 vehicles and has indicated that if the service is satisfactory, several additional orders of the same size will be placed every 3 months over the next 3 to 5 years. Mantenga uses a standard costing system and wants to develop a set of standards for the new vehicle. The usage standards for direct materials such as oil, lubricants, and transmission fluids were easily established. The usage standard is 25 quarts per servicing, with a standard cost of 4 per quart. Management has also decided on standard rates for labor and overhead. The standard labor rate is 15 per direct labor hour, the standard variable overhead rate is 8 per direct labor hour, and the standard fixed overhead rate is 12 per direct labor hour. The only remaining decision is the standard for labor usage. To assist in developing this standard, the engineering department has estimated the following relationship between units serviced and average direct labor hours used: As the workers learn more about servicing the new vehicles, they become more efficient, and the average time needed to service one unit declines. Engineering estimates that all of the learning effects will be achieved by the time that 320 units are produced. No further improvement will be realized past this level. Required: 1. Assume that the average labor time is 0.768 hour per unit after the learning effects are achieved. Using this information, prepare a standard cost sheet that details the standard service cost per unit. (Note: Round costs to two decimal places.) 2. CONCEPTUAL CONNECTION Given the per-unit labor standard set, would you expect a favorable or an unfavorable labor efficiency? Explain. Calculate the labor efficiency variance for servicing the first 320 units. 3. CONCEPTUAL CONNECTION Assuming no further improvement in labor time per unit is possible past 320 units, explain why the cumulative average time per unit at 640 units is lower than the time at 320 units. Show that the standard labor time should be 0.768 hour per unit. Explain why this value is a good choice for the per-unit labor standard.arrow_forward
