Merger review processes are being impacted worldwide as merger control authorities adapt to take account of the consequences of Covid 19. While critical transactions are likely to be reviewed, as far as possible, in accordance with normal practice, many cases may face changes in approach and practice (eg extensions of timelines in certain circumstances). The table below reflects our understanding of the current effects on the merger review process in numerous jurisdictions around the world. It will be updated regularly to track the situation as it evolves. We have applied a red-amber-green 'traffic light' colour-coding background to each jurisdiction to indicate the severity and extent of changes to usual procedures, where red indicates the most significant disruption to or suspension of merger control processes, amber indicates some disruption and changes to normal practice and green indicates, broadly, business as usual.
