How will the current ISIC Code (ISIC3) be altered by the upgrade to ISIC4?

After upgrade to ISIC4, some alterations will take effect on the activities as following three cases:

1.    Some Activities will remain same except renaming of some of them. We call it (1 - 1).
2.    Some Activities will be merged into 1 Activity. We call it
(Many - 1) or (N - 1).
3.    Some Activities will be subdivided into many activities. We call it
(1 - Many) or (1 - N).
4.    Some new activities will be existed.


How will the Commercial Registrations be altered from this upgrade?

Invest Easy was using ISIC3 and all the commercial registrations have added the activities based on ISIC3 standards. After the upgrade to ISIC4, all the altered activities in the Commercial Registration will be automatically upgraded to ISIC4.


What to do in case the Commercial Registration is altered from this upgrade?

All the activities will be upgraded automatically. Only if the CR activity is altered by the case number 3 which is (1 - N), then the investor has to decide either to keep the new subdivided activities or do  submit an application to remove them.
