Oversea investment link insurance policy

I owned several oversea investment link insurance policies. They were acquired before i relocate to work in US. There are no tax treaty, the policies does not clearly spell out the insurance portion except the death and surrender coverage.

My questions:

1. Do I need to file form 8621 for the funds within each policy? 

2 If i have to file form 8621, which section to fill up?

3. How is the calculation of Section V, line 15 and 16? 

 

Thank you.
