Adding a note, according to the initial filings from the SEC:
>As further explained in Amazon’s Insider Trading FAQs, “puts, calls, warrants and other types of option securities” were required to “be cleared in advance with the Legal Department, regardless of whether that employee is otherwise subject to preclearance or to the trading window, even if that employee is not in possession of material nonpublic information.”
Amazon employees require Amazon's Legal approval before trading Amazon options.
