There are strict limits on changes in the holdings of shares held by controllers in licensees or the extent of voting control exercised by controllers in licensees. These limits are outlined in Section GR-4.3. Failure to observe these limits may lead to imposition of enforcement provisions of the Rulebook on the licensee and other penalties on the controller under the provisions of the CBB Law as outlined in Paragraph GR-4.1.2, including loss of voting power or transfer of shares.
