Zany Plastics Ltd, is a large plastics production company located in Dunedin. Due to the Covid-19 pandemic, it has diverted all its production in the last 6 months (January - June 2020) to the fabrication of personal protective plastic face shields. These shields are fabricated in one department, detailed with clips and other attachments and stickers in a second department and disinfected and packed in the third department. Zany Plastics Ltd uses normal costing and a plant-wide (single) overhead allocation rate based on direct wages cost. As the shields require more complicated machine fabrication than Zany's usual products, the management accountant Lucas Turner has suggested that departmental overhead allocation rates would result in more accurate job costs. Exhibit 1 displays the budgeted and actual data for the previous 6 months.
