545 The following are the various methods of re-distribution of service department costs to production departments. 1. Direct re-distribution method 2. Step distribution method 3. Reciprocal Services method a. Simultaneous Equation Method b. Repeated Distribution Method c. Trial and Error Method Direct re-distribution method Under this method, the costs of service departments are directly apportioned to production departments without taking into consideration any service from one service department to another service department. Thus, proper apportionment cannot be done on the assumption that service departments do not serve each other and as a result the production departments may either be overcharged or undercharged. The share of each service department cannot be ascertained accurately for control purposes. Budget for each department cannot be prepared thoroughly. Therefore, Department Overhead rates cannot be ascertained correctly. Illustration 14:In an Engineering factory, the following particulars collected the three months' period ended on 31 March, 2007. You are required to prepare Production Overheads Distribution Summary showing clearly the basis of apportionment where necessary.
