es to articles of association), although the JFTC does investigate such operations in some cases – for instance, if challenged by relevant parties with regard to a violation of other provisions of the AMA. 2.4 Definition of “Control” The AMA does not define or use the concept of “control”. Even if they do not raise any issues of ”control”, transactions are subject to notifica - tions once they meet the thresholds described The AMA distinguishes different notifica - tion thresholds for each type of transaction described in 2.3 Types of Transactions . It should be noted that the thresholds described in this section are the thresholds for a mandatory noti - fication requirement. The JFTC has the authority to review any merger case below the notification thresholds.

The thresholds in a merger are as follows: • the total domestic sales amount of any of the merging parties or the parties involved in the joint share transfer exceeds JPY20 billion; and • the total domestic sales amount of any of the other parties exceeds JPY5 billion.

When the entire business of the transferring company is transferred to a succeeding com - pany, different (higher) thresholds will apply – see the JFTC website.
