Vladimir Putin signed a law that prohibits the placement of depositary receipts for securities of Russian issuers on foreign exchanges.

Companies are given five business days to take "necessary and sufficient" actions to terminate depositary receipt agreements.

Twitter Corporation on Friday approved the use of a "poison pill" to limit Elon Musk's ability to increase his stake. The implication is that any buyer wishing to buy more than 15% of the platform (and gain control) has to put up with conditions whereby existing shareholders can purchase additional shares at a deep discount, although there are no prohibitions on cooperation with the acquiring party. The "poison pill" strategy will be in place until mid-April 2023.
