Guide

Merger or acquisition above thresholds: file pre-merger notification and observe the waiting period

Analyze parties and transaction, calculate current thresholds, coordinate complete filings, pay fees and do not close early.

Priority

Thresholds and rules change and restructuring does not necessarily avoid notification. Premature closing can lead to orders and penalties.

Confirm the scope

Map the buyer, target, affiliates, assets, revenue, control, transaction structure and schedule.

Prepare the information

Apply current party-size and transaction-size thresholds and check exemptions and serial acquisitions.

Complete the process

Prepare each party’s forms and certificates, strategic records, lists, translations and fee payment.

Keep follow-up records

File through the Unit, calculate the waiting period and address any supplementary request before closing.
