Thank you all for the prompt reply. After receiving some new accounting data from there, it seems that the value of the share was over 100k in some years, which definitely involves reporting and amending 8938 for those as well, along with FBARs, even though there was no income in any of them. I just hope this ignorance doesnt introduce big penalties here, since all teh tax compliance is in their country- afterall it is their retirement we are talking about, and would really be unreasonable for us to pay big fines for procedural mistakes out of not knowing/complexity of the issue.
