Here is an interesting situation. CSG didn't put out a press release that Riegner has left the company to become a CFO elsewhere. However, the stock is up more than 4% on the day, a rare up day. I wonder if there is a connection? Thoughts, anyone?

"Riegner joins mix1 after five years as director of corporate development, treasury and M&A at Englewood, Colo.-based CSG Systems International Inc., where he led the financial-related aspects of the corporate development function. At CSG, Riegner was responsible for building and maintaining CSG’s long range financial model, transaction due diligence, financial modeling and ROI/valuation analysis. Riegner also helped lead a variety of corporate treasury functions, including management of CSG’s various capital structure elements, cash management program, credit facilities and equity repurchase program. In addition, Riegner helped lead the closure of five acquisitions representing an investment of approximately $200 million.

Before helping successfully grow CSG’s business, Riegner was a research analyst for Greenwood Village, Colo.-based Janco Partners Inc., and held various research and analyst positions at UBS Pain Webber – Schneider Securities Inc., Nordby International and the Boulder Financial Group. Riegner is a graduate of the University of Colorado at Boulder. Riegner’s financial industry leadership experience also includes holding the Chartered Financial Analyst (CFA) designation since 2005, as well as being an active member of the Association for Investment Management and Research and the Denver Society of Security Analysts"
