About this page
Item 1A of the 10-K on EDGAR was split into its risk factors and, where the company's previous 10-K is on file, each heading was matched to last year's and the text compared word for word. The headings are the filing's own. The one-line readings and the overview were written by a language model from the text of the new, dropped, and rewritten risks; they refer to risks by position and cannot misquote a heading.
