In a normal year, Wilson Industries has $20,000,000 of fixed manufacturing costs and produces 50,000 units. In the current year, demand for its product has decreased and it appears that the company will only be able to sell 40,000 units. Senior managers are concerned, in part because their bonuses are tied to reported profit. In light of this, they are considering keeping production at 50,000 units.

Required 

Write a paragraph explaining why increasing production beyond the quantity needed for current sales will increase profit, and calculate the impact of producing 10,000 "extra” units. Is the managers' proposed action in the best interest of shareholders?
