What to Check

Check the charter, articles, prospectus, plan document, exchange rules, voting rights, dividend priority, conversion terms, transfer restrictions, dilution effect, and whether rights differ by class.

Common Mistakes

  • Assuming common, preferred, restricted, and special shares carry the same rights.
  • Ignoring conversion, redemption, voting, and transfer restrictions.
  • Comparing ownership percentages without checking dilution and outstanding-share definitions.
  • Treating a share-class label as a complete description of investor rights.
