Refer to Page 15 (Indicator HR 2)

I just want to explain that all the years indicated I put "Unknown." This is indicated by referring to the referenced pages I used within this report and also my further research highlighting no answer towards the question thus I listed it as "unknown" from 2017 till 2014. However, as they indicated details can be expressed on earlier reports specifically conducted in forms within questionnaires during 2011. If anyone is interested here is the link:

Note: The format of this document linked is just like all the previous reports on this page its just conducted in 2011 (also the answer is on the same page & heading as listed at the top of this comment).
