12. 7-12 Distributing Service Department Costs (cont’d) –Basis for allocation - Costs are redistributed by ratios that relate the service provided and some functional basis Allocating building service department costs based on floor space occupied by each department Allocating general factory department costs based on the total direct labor cost in the producing department

13. 7-13 Recording Overhead Distribution in the General Ledger At the end of the month the distribution of overhead costs is entered in the general ledger –Manufacturing overhead control is closed into separate departmental overhead accounts –Distribution of service department costs are journalized in the order of allocation
