Each fiscal year is read as-of that year’s own 10-K filing, so nothing restated after the fact leaks backwards. Line items this filer never tagged are omitted. Hover or tap a badge for the diagnostic behind it.

USD in millions, except per-share (EPS) and percentage rows. Values are as originally filed; em-dash = not tagged in that year's filing.
