Porsche is burdened with some 9 billion euros in accumulated debt.The two companies had been in talks over a merger would draw together Porshe cars cars Volkswagen brands including Skoda, Audi and Bentley. Chairman Wolfgang Porsche said the offer from VW was “not feasible.” Analysts say the rejection reveals the extent of the restrictions Porsche is under because of its loan deals.
