These conceptual developments along with growing competitiveness of Iranian financial services industry, have urged top management of this industry to seek more accurate ways on how to better manage their relationships with customers and prevent losses by distinguishing high value and low value customers. Although there are many value measurement tools developed by researchers in different industry settings, there is no such model specified to financial services which brings into account the risk of relationship. This research has focused on developing a value measurement model by which a bank’s management could better decide whether a business credit facility applicant is worth the resources s/he receives. This model is developed based on “customer lifetime value” concept and is risk-adjusted to overcome this common flaw of such models. The risk is modeled by both Delphi method (qualitative risk) and logistic regression method (quantitative risk) to partially resolve the unreliability issues concerned with financial statements in Iran. The model is then tested through a case study- Karafarin Bank (KB)- and new applications such as loan pricing and collateral setting based on this model are suggested to be worked out by KB’s management. Keywords: Customer lifetime value, Delphi method, Qualitative risk, Case study, Mathematical modeling 2 Acknowledgement: This thesis is dedicated to those who have supported me in different aspects; academically, psychologically, and of course financially!! Among these people, my husband and my mother helped me in all aspects and without them I wouldn’t have been able to accomplish this dissertation. I owe this achievement to them in first place. I would also like to convey my sincere appreciation to my supervisor, Dr. Albadvi, who dedicated enough time to my piece of work so that I could get my desired research quality. Many thanks to Karafarin Bank and all Banking experts on our Delphi panel who devoted great amount of time and expertise for completion of this thesis. Hope the results of this research can improve the marketing performance at Iranian financial services industry. 3 Table of Content Chapter 1 ........................................................................................................................... 10 Introduction ....................................................................................................................... 10 1.
