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 $21 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		15,800 Units Per Year
Direct materials	$	5	$	79,000
Direct labor		7		110,600
Variable manufacturing overhead		4		63,200
Fixed manufacturing overhead, traceable		6*		94,800
Fixed manufacturing overhead, allocated		9		142,200
Total cost	$	31	$	489,800

*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. 1b. Should the outside supplier’s offer be accepted?         Reject     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 $46,080 per year. Compute the total cost of making and buying the parts.

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 $21 per unit.

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     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 $46,080 per year.

Should Troy Engines, Ltd., accept the offer to buy the carburetors for $21 per unit?         Accept Explanation:1.     Per Unit Differential Costs   15,800 Units     Make   Buy   Make   Buy   Cost of purchasing     $ 21        $ 331,800     Direct materials $ 5         $ 79,000         Direct labor   7           110,600         Variable manufacturing overhead   4           63,200         Fixed manufacturing overhead, traceable1   2.40           37,920         Fixed manufacturing overhead, common   -           -     -       Total costs $ 18.40     $ 21    $ 290,720   $ 331,800       Difference in favor of continuing to make the carburetors $2.60 $41,080     1Only the supervisory salaries can be avoided if the carburetors are purchased. The remaining book value of the special equipment is a sunk cost hence, the $4 per unit depreciation expense is not relevant to this decision.   Based on these data, the company should reject the offer and should continue to produce the carburetors internally.     2a.     Make   Buy   Cost of purchasing (part 1)     $ 331,800     Cost of making (part 1) $ 290,720         Opportunity cost—segment margin forgone on a potential new product line   46,080           Total cost $ 336,800   $ 331,800       Difference in favor of purchasing from the outside supplier   $5,000       2b. Thus, the company should accept the offer and purchase the carburetors from the outside supplier.
