The activist investor disclosed his effort in a tweet — apparently coordinated with a release from Time magazine promoting its new cover story about him where he discusses his proposal. “I’m not against the management of this company,” he told Time. But with $147B “they’ve just got too much money on their balance sheet.” He adds that CEO Tim Cook “is doing a good job with the business. I think he’s good whether he does what I want or not.” But “Apple is not a bank.” Apple told Time that “As part of our regular review process, we are once again actively seeking our shareholders’ input on our program, and as we said in October, the management team and our board are engaged in an ongoing discussion about it which is thoughtful and deliberate.” Icahn launched his campaign for an Apple buy-back in August. Today’s news did not immediately affect Apple’s trading price, down less than 1% ahead of the close.
