Scandal about the merger with Landis and Gyr
In 2002 the Siemens Group sold seven subsidiary companies to the US financial investor KKR. Most affected by this sale was the Swiss company Siemens Metering, located in Zug. 160 out of 360 employees lost their jobs. Siemens Metering was the result of the merger between Siemens and Landis & Gyr in 1998. The documentary “Verlorene Welt – Aus dem Innenleben des einstigen Konzerns Landis & Gyr”  by Claudia Schmid and Michael van Orsouw involves the subject and had its first performance at the Solothurn Film Festival 2006. Pension funds scandal
Siemens sharpened 2006 the rules of conduct for its employees as a reaction to the financial scandal about disloyalty and assumed corruption. Peter Rüegg and Siemens Manager Roland Rümmeli found themselves in the sight of the investigations. Rümmeli was accused to have redirected kickbacks to his private accounts. The laid off portfolio manager paid back the illegal drawn money (400’000.00  CHF) to Siemens. References
