Where this comes from

A public company must file a current report on Form 8-K with the SEC within four business days when a director leaves or is elected, or when its chief executive, chief financial, chief accounting or chief operating officer, or another named executive, departs or is appointed. That disclosure goes under Item 5.02 of the report.

Every change on this page is taken from one of those filings and quoted in the company's own words, with a link to the filing, so it can be checked at the source. Where a filing names the person, the role and the date a change takes effect, they are shown beside the quote. Where it does not, the quote stands on its own. A filing states what changed; it rarely states why, and neither does this page.
