Croatian to English Medical Medical: Pharmaceuticals product insert/market placement

This is a document from the Croatian Ministry of Agriculture, Forestry and Water Management, issuing approval for market placement of a veterinary drug for domestic livestock. Most of the document is essentially a product insert, but at the end of the document there is a section explaning the background of the importing company, and of the Ministry's approval process. The heading of the section is:

obrazloženje

I realize this can be translated as "exposition" or "explanation". But I'm not satisfied with this translation. Any other ideas?

Thank you in advance for your help.
