Elon Musk has reached a deal with the Securities and Exchange Commission, the two parties said in a legal filing on Friday. The new agreement provides much more detailed guidance about when tweets and other public statements by Musk must be approved by Tesla lawyers.

Musk's original deal with the SEC was announced last September. It required Musk to obtain pre-approval for tweets that "contain or could contain" information that's material—legal jargon for information that's significant to shareholders. While the SEC expected Musk to begin regularly clearing tweets with lawyers, Musk interpreted this language as giving him significant discretion to decide for himself which tweets contained material information. As a result, he didn't seek legal review for any tweets in the first few months the agreement was in effect.
