Musk later tweeted: "Legally required officers of a corporation are president, treasurer & secretary. Guess I have to keep 1st one or it will confuse the authorities."
Musk has agreed to pay a $20 million fine and step aside as Tesla chairman for three years to settle charges with the U.S. Securities and Exchange Commission related to his August 7 tweet about taking Tesla private.

Musk's compulsive tweeting and erratic behavior, which included smoking marijuana during a video interview, has raised concerns about his leadership, with several Wall Street analysts and some investors urging Tesla to appoint a strong second-in-command.
