Italian to English Bus/Financial Law: Contract(s)

"Ogni fornitura/prestazione è regolata da un contratto sottoscritto dalle parti, coerentemente con l’assetto procuratorio vigente in ciascuna società".

They are talking about the purchase and sale of goods and services between companies in the same group.

Do they mean purchasing/procurement, or is there a legal implication here? "Procuratorial" sounds a bit too Roman for my liking. However ... .
