At the moment, Porsche SE owns 50.7 percent of Volkswagen AG. Porsche AG, the company that actually produces Porsches, is currently owned by Porsche Zwischenholding GmbH, a company held as a joint venture between and Volkswagen AG and Porsche SE.
If the merger goes ahead, it will give Volkswagen AG control over Porsche AG, which, in turn, will help it produce more cars as a company overall. This merger has been part of Volkswagen's strategy to become the largest manufacturer for some time. In 2009, Porsche SE and Volkswagen AG announced a merger would occur in 2011.
Both Volkswagen and Porsche are set for further "distinct growth" according to Volkswagen CEO Martin Winterkorn, despite the current "challenging" economic conditions.
The meeting will be held in mid-December this year.
