Master Thesis at BI Norwegian Business School The study of municipalities` investment choices: Eight Norwegian municipalities` investments in financial products during 2001 - 2007 Program: Master of Science in Business and Economics Supervisor: Salvatore Miglietta Written by: Minh Nguyen Lars Ølnes Examination code and name: GRA 19003 –Master Thesis Submission date: 02.09.2013 Place of study: BI Oslo Master Thesis GRA19003 02.09.2013 “The global liquidity is enormous and only a significant disruptive event could create difficulty in the market. As long as the music is playing, you’ve got to get up and dance. We’re still dancing.” Charles Prince Former CEO of Citigroup July 2007 Page 2 Master Thesis GRA19003 02.09.2013 Summary This paper investigates the change in riskiness of eight Norwegian hydro power municipalities’ investments in complex financial products offered by Citigroup through the brokerage firm Terra Securities AS during the period 2001-2007. The investments were financed by restructuring the municipalities` annual revenue from concession fees and power. Using Monte Carlo simulations, this paper estimates the change in riskiness by comparing the Cash Flow at Risk between two portfolios comprising of (1) restructuring the concession fees and power and investing in Credit Linked Notes, and (2) no restructuring of the concession. Evidence of increased riskiness is found for the eight municipalities when entering into these products.
