Sisel Company has two divisions, the Optic Lens Division and the Camera Division. The Camera Division may purchase lenses from the Optic Lens Division or from outside suppliers. The Optic Lens Division sells products both internally and externally. The market price for lenses is $2,500 per carton (100). Newt Watt is the controller of the Camera Division, and Tani Trudeau is the controller of the Optic Lens Division. The following conversation took place between Newt and Tani:

Conversation

Newt (Camera)	I hear you are having problems selling lenses out of your division. Maybe I can help.
Tani (Optic Lens)	You've got that right. We're producing and selling at about 75% of our capacity to outsiders. Last year we were selling at capacity. Would it be possible for your division to pick up some of our excess capacity? After all, we are part of the same company.
Newt	What kind of price could you give me?
Tani	Well, you know as well as I that we are under strict profit responsibility in our divisions, so I would expect to get market price, $2,500 per carton (100).
Newt	I'm not so sure we can swing that. I was expecting a price break from a sister division.
Tani	Hey, I can only take this sister stuff so far. If I give you a price break, our profits will fall from last year's levels. I don't think I could explain that. I'm sorry, but I must remain firmmarket price. After all, it's only fairthat's what you would pay from an external supplier.
Newt	Fair or not, I think we'll pass. Sorry we couldn't have helped.

What to Do

What are the Responsibility centers of Camera Division and Optic Lens Division? -- cost, profit, or investment center? What is the main responsibility for that corresponding center as mentioned in the case?

Camera Division: Was Newt behaving ethically by trying to force the Optic Lens Division into a price break? Why?

Optic Lens Division: Comment on Tani's reactions. Is her comment valid? Was Tani's refusal made in the best interest of the Company?
