Each label is a form type or an 8-K item as filed; each row links to the filing.
Source: Lam Research Corp's EDGAR filing history, the last ten years. The labels are the form types and 8-K item numbers the company filed under, not a reading of what it wrote — an item 5.02 can be a chief executive fired or a director retiring on schedule — so each row links to the filing.
