 * Who owns a stock, as shares and % of shares outstanding: 13F institutions, insiders (Forms
 * 3, 4 and 5, single-class issuers only), 13D and 13G blocks no 13F report already holds, and
 * the remainder, flagged rather than clipped when negative. Registered funds are shown but never
 * summed, since their shares sit inside their advisers' 13F reports. Each holder counts once:
 * insiders who file 13Fs, holders a 13F filer reports, and the filers and persons of any 13D or
 * 13G that names a 13F filer, directly or through filings naming one another, are left out of
 * the other lines, by CIK and SEC reporting links, never by name. A foreign private issuer's
 * count is in ordinary shares, a different unit, so it gets no percentages or remainder. The
 * 13F shares are also split by holder type, style and location.
