I don't think there needs to be much "reporting".

Intel has a rule where c-suite and up execs who have been at the company 5+ years must hold a minimum amount of stock. For the CEO, that number is 250,000. The CEO recently exercised options and immediately sold them, holding onto the absolute minimum required (250k).

This is all available on the SEC's website, trades like this are reported to the SEC and are considered public information.

Small correction, but generally someone like that exercises their options and sells them for profit, keeping their shares that they've had since whenever. In this case, he exercised the options, sold those shares, and then lowered the amount of shares he had beyond that to the absolute minimum (250k).

> that also predates this announcement

Apparently, Microsoft has been releasing patches for NT since November, so it isn't exactly predating the bug.
