Summer Time Corporation (STC) is located in Toronto, Ontario. The company is owned by 2 friends that met each other while attending Algoma University. The company manufactures two summer time game products, Bocce Ball Sets and Croquet Sets. Croquet Sets were added as a product line two years ago. Croquet Sets are the more complex of the two products, requiring one hour of direct labour time per unit to manufacture, compared to one-half hour of direct labour time for Bocce Ball Set. Croquet Sets are produced on an automated production line.

Indirect costs are currently allocated to the products on the basis of direct labour hours. The company estimated it would incur $332,500 in manufacturing overhead costs and produce 6,000 units of Croquet Sets and 20,000 units of Bocce Ball Sets during the current year.

The company unit costs for materials and direct labour are as follows:
