Context
A Rule 10b5-1 plan allows prearranged trades and is often used to avoid trading based on inside information; such trades are generally considered routine. For retail investors, purchases are usually more informative about insider conviction than routine sales; this report documents a planned sale under a 10b5-1 arrangement rather than an ad hoc trade.
