Business development

In 1999, the steering systems division was made separate and became the new ZF Lenksysteme GmbH, an independent, 50:50 joint venture between ZF Friedrichshafen and
Robert Bosch GmbH.
In 2007 ZF Friedrichshafen managed to increase its business volume about 8% to billion. The operating profit was about million. In 2008 ZF had a profit of million from a total business volume of billion. During the financial crisis ZF was one of the companies hit most. Its business volume decreased in turnover to billion. Total loss was about million. According to the current development ZF is forecasting sales growth of about 10%, which would be above the industry average.
Due to the financial crisis ZF received a credit of about million by KfW. At the end of the term, it has to be paid back with interest. Being a state bank, the KfW aid is not considered governmental support. ZF is about to save million without reducing its permanent staff. Contracts of short-term employees were not extended. Total number of employees was reduced from 63,000 to 59,000 worldwide. According to CEO Härter, there is no need for further employee reduction.
