1. Customer Lifetime Value is useful to marketers because:

   	a.	It allows the marketer to build an accurate picture of customers spending patterns and the value of building loyalty.
   	b.	It allows marketers to correlate the stage of product lifecycle with the value that can be created at a particular point in the customers life.
   	c.	It is not a useful tool for marketers as customers have more choice than ever before meaning that they are no longer loyal to any one product.
   	d.	It allows the marketer to gain more sales because of what a customer spends over their lifetime.
   	e.	It allows the marketer to calculate the value of life style marketing rather than product marketing
