Munish Automobiles Ltd produces electrical accessories like meters, transformers, switchgears and automobile accessories like taximeters and speedometers. Munish buys the electrical components but manufactures all mechanical parts within its factory which is divided into four production departments. Machining, Fabrication. Assembly and Painting and three services departments - Stores, Maintenance, and Works Office. Though the company prepared annual budgets and monthly financial statements, it had no formal cost accounting system. Prices were fixed on the basis of what the market can bear. Inventory of finished stocks was valued at 90 percent of the market price assuming a profit margin of 10 percent. In March the company received a trial order from a government department for a sample transformer on cost-plus-fixed-fee basis. They took up the job (numbered by the company as Job No.879) in early April and completed all manufacturing operator before the end of the month. Since Job No. 879 was very different from the type of transformers they had manufactured in the past. The company did not have a comparable market price for the product. The purchasing officer of the government department asked the company to submit a detailed cost sheet for the job giving as much details as possible regarding material labour and overhead costs. Munish, as part of its routine financial accounting system had collected the actual expenses for the month of April, by 5th of May. Some of the relevant data are given in Exhibit I. The company tried to assign directly, as many expenses as possible to the production departments. However, it was not possible in all cases. In many cases an overhead cost, which was common to all departments had to be allocated to the various departments using some rational basis. Some of the possible bases were collected by company's accountant. These are presented in exhibit II. He also designed a format to allocate the overhead to all the production and service departments. It was realized that the expenses of the service departments on some rational basis. The accountant thought of distributing the service departments costs on the following basis.

Works office costs on the basis of direct labour housh.

Maintenance costs on the basis of book value of plant and machinery.

Stores department costs on the basis of direct and indirect materials used.
