Question;American Guitar Company manufactures two different high quality acoustic guitars for retailers: beginner model and professional model. The company has two service departments: the maintenance department and the power department, and two manufacturing departments: the construction department and the finishing department. American Guitar chooses the reciprocal method to allocate service department costs. It uses operation costing to assign direct materials and conversion costs to its products, and absorption costing with normal costs for external reporting purposes.In the Construction Department, the wooden guitars are built by highly skilled craftsmen and coated with several layers of lacquer. Then the units are transferred to the Finishing Department, where the bridge of the guitar is attached and the strings are installed. The guitars also are tuned and inspected in the Finishing Department. American Guitar estimates to have an annual practical capacity of 6000 guitars (1500 units of professional model and 4500 units of beginner model). The budgeted sales for 2013 are 1300 units professional model and 4300 units of beginner model. The diagram below depicts the manufacturing process.The following historical information has been collected from American Guitar's accounting information systems:2009201020112012Annual sales4146(B) & 1611(P)4456(B) & 1256(P)4668(B) & 1322(P)4075(B) & 1300(P)July sales393(B) & 183(P)398(B) & 163(P)405(B) & 168(P)372(B) & 155(P)2012Total Overhead ($)Total DLH of the two manufacturing departmentsJanuary134,0002,210February137,0002,280March148,0002,510April155,0002,790May157,0002,980June165,0003,590July169,0003,490August168,0003,030September163,0003,040October157,0003,380November139,0002,420December133,0002,100Total1,825,00033,820 American Guitar?s directand indirect MOH costs for the two service and two manufacturing departments in 2012:Power DepartmentMaintenance DepartmentConstruction DepartmentFinishingDepartmentTotal AmountLabor-hours20222032189501487037,874Kilowatt-hours2,0007,00040,80030,20080,000Maintenance hours140608001,0002,000Direct fixed costs$60,000$36,000$480,000$432,000$1,008,000Direct variable costs$58,000$40,000$346,800$358,200$803,000Indirect fixed costs$9,600Indirect variable costs$4,400American Guitar does not expect significant changes in its manufacturing costs in 2013.At the end of June 2013, the balance in American Guitar?s Materials Inventory account, which included 150 pounds of grade A veneered wood, was $2,640, the balance in the finished-goods inventory, which was valuated using the last-in, first-out (LIFO) method, consisted of 2 models, was $16,600.Quantity and Unit CostBeginner model20 units @ $430 eachProfessional model10 units @ $800 eachThe following pertains to the month of July.There were no beginning inventories in both manufacturing departments.American Guitar's work-in-process inventory on July 31 consisted of two jobs: B0642 and P0642.

Why?Part 2Submit a hard copy of your work and email an Excel workbook to support your calculations on or before the due date for questions 1 ? 11.Recently, American Guitar has faced intense competition from oversea guitars manufacturers. Her competitors sell similar quality guitars averaged 25% less. American Guitar considers implementing the standard costing to improve cost control. After conducting task analysis in the manufacturing departments, American Guitar establishes the following standards:1) Each finished guitar contains seven pounds of veneered wood. In addition, one pound of wood is typically wasted in the manufacturing process.2) The veneered wood used in the beginner model has a standard price of $12 per pound and the professional model has a standard price of $18. The other parts needed to complete each beginner guitar (professional guitar), such as the bridge and strings, cost $15 ($18) per guitar.3) The labor standardsfor American Guitar's two manufacturing departments are as follows:Construction DepartmentFinishing DepartmentBeginner model (B)3 hours of direct labor at $18 per hour2 hours of direct labor at $20 per hourProfessional model (P)4 hours of direct labor at $18 per hour6 hours of direct labor at $20 per hour8. Assuming American Guitar implements the standard costing, and calculate the followings:- Direct material and direct labor variances- variable manufacturing overhead variances for both manufacturing departments in July.- fixed manufacturing overhead variances for both manufacturing departments in July.- standard cost for the beginner model and the professional model.9. Prepare the journal entries to record the transactions in July using the standard costing.10. Prepare entries to close all the variances using the proration method.11. Do you recommend American Guitar to price its products based on its standard costs? Why?Prepare a presentation to answer the following questions:12. Do you recommend American Guitar to keep its current cost-accounting system or to implement the standard costing system? Why?13. Explain the interpretation and possible interactions between the variances calculated by the standard costing.14. Write a memo to the company evaluating American Guitar?s July performance and indicate any appropriate action for management to fine-tune its strategy.Direct-material is added at the beginning of manufacturing process in construction department.The direct-material and conversion costs are incurred uniformly throughout the process in finishing department.American Guitar believes that overhead is affected by total monthly DLH of the two manufacturing departments.For amanufacturingdepartment, direct costs refer only to overhead costs that are directly traceable to the department.Power department is to provide electricity to maintenance, construction and finishing department. Its service is measured by the kilowatt-hours. The kilowatt-hours provided by the department for 2010 & 2011 were 84,200 & 88,000 respectively.Maintenance department is to maintain all the equipment in power, construction and finishing department. Its service is measured by the maintenance hours. The maintenance hours provided by the department for 2010 & 2011 were 2,150 and 2,240 respectively.Direct-labor rates include employee benefits.
