1.1 Membership of Supranational Organization
1.1.1 Is the jurisdiction a member of/party to a supranational jurisdiction?
1.1.2 Is the jurisdiction itself a supranational jurisdiction?

2.1 Mandatory or voluntary
2.1.1 Is filing mandatory or voluntary?
2.2 Suspensory effect
2.2.1 Must completion of the transaction await clearance by the relevant authorities?
There are two types of notifications, and whether completion of the transaction must await clearance by the authorities depends on the size of the undertakings concerned:
Following a pre-closing notification, completion of the transaction must await clearance by the competition authority.
Pre-closing notification is required where one or more of the undertakings concerned are a “large company”, defined as an undertaking with global assets or turnover of at least KRW 2,000,000,000,000 in the last financial year, measured on group level.
Where none of the undertakings concerned qualify as a “large company”, as defined above, completion of the transaction can take place before clearance is obtained.
In this case, the Fair Trade Commission requires that the transaction be notified no later than 30 days of completion.
