Answer:
Innova
a) Make or Buy IMC2 Incremental Analysis:
Make IMCs (per unit)
Direct material     $61.48
Direct labor         37.19
Material handling     7.16
Variable overhead   71.60
Total unit cost      177.43
Buy IMC2 (per unit)
Purchase price      $230
Net Income will decrease by ($52.57) if IMC2 is bought.
b) Innova should not purchase the component. Â It costs more to buy IMC2 than to make it based on incremental analysis.
Explanation:
a) Incremental Analysis is a decision-making technique used in business to determine the true cost difference between alternatives. Â It is also called the relevant cost approach, marginal analysis, or differential analysis. Â Using incremental analysis, sunk cost or past cost is disregarded as irrelevant. Â The fixed cost element equalling $47.74 per unit is a sunk cost that is not relevant for incremental analysis.
b) In a make or buy decision, the company considers if internalization of production will be of greater economic benefits than outsourcing.
c) Variable overhead is calculated as ($126.50 - $7.16) x 60% = $71.60
