The Porsche and Piëch families might have ironed out their personal differences but events within their businesses have escalated since Sunday when they announced they had amassed a further 31.5% in Volkswagen, pushing their ownership to over 74%.
However, controversy has centred on the fact that the 31.5% is in the form of cash settled options, purchased to hedge against price risks.
On the back of this, VW shares experienced a huge surge earlier this week. At one stage the price exceeded €1,000 per share, briefly making it the world's most valuable company.
