Former U.S. Securities and Exchange Commission Chairman Arthur Levitt, “once disinvited from joining Apple Inc.’s board amid differences over corporate governance, said the company has disclosed enough about CEO Steve Jobs’s health, reports “Bloomberg Businessweek” (http://macte.ch/qBihB).

Levitt, who headed the SEC from 1993 to 2001, told “Bloomberg Businessweek” the severity of Jobs’s cancer is well established and the board doesn’t need to share more details with the public.

“It’s easy to criticize the board, but I think the reality is that someone who owns Apple stock has got to be deaf, dumb and blind not to know that Jobs has an illness that can reoccur at any time,” he said in a telephone interview. “Jobs going on medical leave sends a message to the market. An intelligent investor should know the risks of Jobs having a relapse. For the board to opine on what the extent of the illness is right now I don’t think is really necessary.”
