Bernie Ecclestone insists he is happy rather than upset that Nico Rosberg and some of F1's biggest names have elected to retire.
F1 veteran and 2009 world champion Jenson Button has called time on his long career, as has Felipe Massa, although the latter may be on the verge of delaying his retreat if Valtteri Bottas is confirmed at Mercedes for 2017.
F1 supremo Ecclestone insisted he is not angry with Rosberg, despite the fact he is leaving the sport without its reigning world champion in 2017.
"He did his job," the 86-year-old Briton told Germany's Sport Bild. "He wanted to become world champion and he has it now. Why should he continue? I can understand him."
In fact, Ecclestone said Rosberg's exit actually "helps" F1.
"It shows that the world champion has a clever head on his shoulders. He has reached his great goal, so we can't blame him for wanting to do something else in his life.
As for Button and Massa, Ecclestone said: "I am glad that they are able to get out of their own choosing, as in the old days we lost drivers for other reasons, like if they were killed in accidents.
"So these retirements are even joyous events for me," he insisted.
