consideration

Hi,

How would you approach a question that ask, how does the nature of consideration affect the calculation of goodwill.

I have explained about the different types of consideration such as cash, deferred cash (how it must be discounted), contingent consideration(use the fair value), shares (prices are volatile therefore may change and change the value of goodwill) etc however i am unsure how to link it back to the calculation of goodwill and how it affects it.
