Pricing policies and strategies

You need to watch the free lectures on pricing because they are explained in the lectures - I cannot type out all of the lectures here :-) Our free lectures are a complete course for Paper F5 and cover everything needed to be able to pass the exams well.

I read the lecture but I did not understand can you explain it briefly?????

It is because the pricing policies depend very much on the type of product and the expected life of the product. Have you actually watched the free video lectures (as opposed to simply reading the notes)? Because I do give examples of the types of situation when different policies might be useful within the lectures.
