Part I
ABC Ltd uses a predetermined overhead rate to estimate the total manufacturing overhead for the quarter ending 30 September 2019. Based on this, the estimated total manufacturing overhead cost is $200,200 and the estimated level of activity is 11,000 machine hours.
By the end of 30 September 2019, ABC Ltd incurred actual total manufacturing overhead costs of $195 000 and 10 500 total machine hours.

Part II
The management at Han Products is trying to decide whether to continue manufacturing a part or to buy it from an outside supplier.
Han Products manufactures 30,000 units of part S-6 each year for use on its production line. At this level of activity, the cost per unit for part S-6 is:
Direct materials
$3.60
Direct labour
10.00
Variable manufacturing overhead
2.40
Fixed manufacturing overhead
9.00
Total cost per part
25.00
An outside supplier has offered to sell 30,000 units of part S-6 each year to Han Products for $21 per part. If Han Products accepts this offer, the facilities now being used to manufacture part S-6 could be rented to another company at an annual rental of $80,000. However, Han Products has determined that two-thirds of the fixed manufacturing overhead being applied to part S-6 would continue even if part S-6 were purchased from the outside supplier.
Required:
(a) Make a recommendation on whether S-6 should be manufactured or purchased. Support your answer with appropriate incremental analysis. (8 marks)
(b) What non-financial factors should management consider in making this decision? (4 marks)
