Cutolo's NCO was becoming more powerful by encroaching and taking over other clan's territories and was able to break the traditional power held by single Camorra families. The NCO was too violent to be confronted by any of the families that were initially too weak and divided, and easy to intimidate. If other criminal groups wanted to keep their business, they were obliged to pay the NCO protection on their activities, including a percentage for each case of cigarettes smuggled into Naples. This procedure came to be known as ICA ("Imposta Camorra Aggiunta" – or Camorristic Sale Tax), copying the state VAT sale tax IVA (Imposta sul Valore Aggiunto).
