Zubick Corporation produces and supplies 2 types of component parts to industrial equipment manufacturers. These parts are known as X123 and R907.

There are 2 departments in the factory: the machining and assembly departments. The machining department has highly automated operations, while assembly has labour-intensive operations.

Table 1: Annual production data by product

The overhead cost incurred in the Machining department was $1,300,000, while the overhead cost in the Assembly department was $350,000.

Table 2: Annual overhead costs and production activity by department

The manager, Rex, decided to allocate costs to the 2 products in the following manner: he divided the total overhead costs of $1,650,000 by the total number of labour hours utilised in the factory (ie (1000 x5) plus (2000 x 15) = 35,000 DLH).

Therefore his overhead rate was $1,650,000/35,000 = $47.14 per DLH.

The overhead allocated to each product using Rex's rate was as follows:

Product X123 = 5 DLH x$47.14 = $235.70
Product R907 = 15 DLH x $47.14 = $707.10

But Rex was losing sales of product R907 to his competitor who was able to sell a similar product at a lower price, and recover all costs of production.

Additional information:

Tables 3 and 4 show how much direct labour and machine time is consumed by each product in each production department.
