why it matters
Rule 8.3 requires holders of at least 1% of a company's shares to disclose dealings while its securities are subject to a takeover offer. These notices contain no new deal terms and usually have little effect on share prices. For traders, they show where large funds are building positions, and they are a prompt to check the companies' own announcements.
