25) kleffman corporation is presently making part x31 that is used in one of its
products. a total of 2,000 units of this part are produced and used every year. the
company’s accounting department reports the following costs of producing the part at
this level of activity:
an outside supplier has offered to produce and sell the part to the company for $23.40
each. if this offer is accepted, the supervisor’s salary and all of the variable costs,
including direct labor, can be avoided. the special equipment used to make the part was
purchased many years ago and has no salvage value or other use. the allocated general
overhead represents fixed costs of the entire company. if the outside supplier’s offer
were accepted, only $1,000 of these allocated general overhead costs would be avoided.
if management decides to buy part x31 from the outside supplier rather than to continue
making the part, what would be the annual impact on the company’s overall net
operating income?
a.net operating income would decline by $5,600 per year
b.net operating income would decline by $1,800 per year
c.net operating income would decline by $4,600 per year
