The UK Takeover Panel is consulting over what to do about dealing disclosures. The UK system that regulates public company takeovers is comparatively tolerant over dealings during an offer and permits participants to deal when they would be barred from doing so in the US. This approach is consistent with the market's overall efficiency, which continues relatively unhampered during a takeover.
The British approach is made possible only by an insistence on rapid dealing disclosure during a bid, the objective of which is to achieve an appropriate level of transparency for market participants.
