Fiat Chrysler says it did not know about Marchionne's illness

Fiat Chrysler said it knew nothing about the medical condition of Sergio Marchionne after a Swiss hospital said on Thursday it had been treating the deceased chief executive for more than a year.

"Due to medical privacy, the company had no knowledge of the facts relating to Mr. Marchionne's health," a Fiat Chrysler spokesman said.

Questions have been raised about how long Marchionne, who died on Wednesday, was ill and how much the company knew before it made the situation public.

Marchionne rescued Fiat and Chrysler from bankruptcy after taking the wheel of the Italian carmaker in 2004 and he multiplied Fiat's value 11 times through 14 years of canny dealmaking. He was due to step down at FCA in April next year.

"The company was made aware that Mr. Marchionne had undergone shoulder surgery and released a statement about this," the spokesperson said.

"On Friday, July 20, the company was made aware with no detail by Mr. Marchionne's family of the serious deterioration in Mr. Marchionne's condition and that as a result he would be unable to return to work. The company promptly took and announced the appropriate action the following day."

Asked whether the scope of the statement included the board and the chairman, the company declined to comment.

In emailed comments, Marchionne's family confirmed the companies had not been aware of his health conditions.

"At the end of last week FCA was made aware Sergio Marchionne would no longer be able to return to work without mentioning any further details," the family said.

The announcement of the death of Marchionne, 66, one of the auto industry's most tenacious and respected CEOs, drew tributes from rivals and tears from his closest colleagues on Wednesday.

University Hospital Zurich said earlier on Thursday Marchionne had been treated for a serious illness for more than a year before his death.

Marchionne had fallen gravely ill after what the company had described as shoulder surgery at a Zurich hospital. He was replaced as chief executive last weekend after Fiat Chrysler (FCA) said his condition had worsened.

"Mr. Sergio Marchionne was a patient at USZ. Due to serious illness, he had been the recipient of recurring treatment for more than a year," the hospital said in a statement. "Although all the options offered by cutting-edge medicine were utilized, Mr. Marchionne unfortunately passed away."

University Hospital Zurich declined to comment on Marchionne's illness, but said it deeply regretted his death and expressed its condolences to his family.
