Repeal and savings preserve prior actions, rights and ongoing buy-back offers under the new buy-back regulatory framework. The regulations repeal the earlier buy-back rules while preserving continuity: acts, exemptions, fees, adjudications, enquiries, investigations and show-cause notices under the repealed regulations shall be deemed done under corresponding provisions of the new regulations; prior rights, obligations, liabilities and remedies remain unaffected; announced buy-back offers must be continued and completed under the repealed regulations; and references to the repealed rules in other Board instruments shall be read as references to the corresponding provisions of the new regulations.
