Chubb Ltd.’s Chief Executive Evan G. Greenberg will be leaving Coca-Cola’s board of directors this Saturday, according to the Atlanta soft drink giant.

Greenberg, 61, who has been on Coca-Cola’s board since 2011, said Monday that he is resigning from the company’s board because of increasing demands at his day job. He served on Coke’s audit and finance committees.

In January, the specialty insurer Greenberg heads, formerly known as Ace Ltd., acquired insurer Chubb Corp. in a $28 billion deal. He now heads the combined companies as CEO and chairman.

“I have enjoyed the opportunity of serving on the board over the past few years and believe (Coca-Cola) has strong plans in place for the future,” said Greenberg, in a press release.
