Question

Exercise 10-3 Make or Buy a Component [LO10-3]

Troy Engines, Ltd., manufactures a variety of engines for use in heavy equipment. The company has always produced all of the necessary parts for its engines, including all of the carburetors. An outside supplier has offered to sell one type of carburetor to Troy Engines, Ltd., for a cost of $43 per unit. To evaluate this offer, Troy Engines, Ltd., has gathered the following information relating to its own cost of producing the carburetor internally:

   

		Per Unit		14,500 Units Per Year
Direct materials	$	13	$	188,500
Direct labor		15		217,500
Variable manufacturing overhead		2		29,000
Fixed manufacturing overhead, traceable		6*		87,000
Fixed manufacturing overhead, allocated		17		246,500
Total cost	$	53	$	768,500

*40% supervisory salaries; 60% depreciation of special equipment (no resale value).

   

Required:

1a.	Assuming that the company has no alternative use for the facilities that are now being used to produce the carburetors, compute the total cost of making and buying the parts. (Round your Fixed manufacturing overhead per unit rate to 2 decimals.)

    

      

1b.	Should the outside supplier’s offer be accepted?
	Reject Accept

    

2a.

Suppose that if the carburetors were purchased, Troy Engines, Ltd., could use the freed capacity to launch a new product. The segment margin of the new product would be $165,700 per year. Compute the total cost of making and buying the parts. (Round your Fixed manufacturing overhead per unit rate to 2 decimals.)

   

      

2b.	Should Troy Engines, Ltd., accept the offer to buy the carburetors for $43 per unit?
	Accept Reject
