By this period, popular opposition to the D'Arcy oil concession and royalty terms whereby Iran only received 16 percent of net profits was widespread. Since industrial development and planning, as well as other fundamental reforms were predicated on oil revenues, the government's lack of control over the oil industry served to accentuate the Iranian Government's misgivings regarding the manner in which APOC conducted its affairs in Iran. Such a pervasive atmosphere of dissatisfaction seemed to suggest that a radical revision of the concession terms would be possible. Moreover, owing to the introduction of reforms that improved fiscal order in Iran, APOC's past practise of cutting off advances in oil royalties when its demands were not met had lost much of its sting.
