Percent = "% of class represented by amount beneficially owned" for this reporting person in the filed 13D/13G.
Shares = reported beneficial ownership amount for the same row (not portfolio shares from 13F).
Amendments (/A) can repeat the same holder over time, so rows should not be summed.
Extraction is best-effort from filing text and can be missing or noisy; verify exact figures via the SEC link in each row.
