The SEC's list of Costco Wholesale Corp's recent filings reaches back to October 25, 2016; registration statements and other prospectus filings aren't shown. Every filing on EDGAR
The comparison takes Item 1A (risk factors) of the latest 10-K and of the one before it, splits each into paragraphs, and matches every paragraph to its closest counterpart by the words they share. Dates and figures are set aside, so a paragraph whose only change is the year counts as unchanged. It is done by rules, not by anyone’s reading: the sentences are the company’s own, quoted as filed.
