Chambers Legal Practice Guide: Merger Control

An ever-increasing number of jurisdictions are adopting or amending their existing merger control regimes. As a result, complexity, uncertainty and burdens for multinational merging parties are also on the rise. Navigating the patchwork of rules and requirements of merger control regimes around the world can increase cost and cause delays, both of which are of the utmost concern to many parties in the current uncertain economic and financial climate. Uncertainty may be compounded as new and untested regimes come online, non-competition concerns find their way into merger control reviews and experienced regulators change - or claim to change - their substantive analytical frameworks. Published by Chambers & Partners, Charles (Rick) Rule and Jonathan Kanter authored the chapter analyzing merger enforcement in the USA.
