Makers Ltd is a manufacturing company that has three production departments known as
Department A, B and C. The production overhead is absorbed on the basis of a percentage
of direct labour cost for the factory as a whole. It has been suggested that a departmental
overhead absorption rate would result in more accurate job costs.
Below are the budgeted and actual data for the year ended 31’ October, 2008.
