There are a couple of people on the council who have speculated about the fact that there are some countries, notably Russia and Iran, to the extent that it's not subject to sanctions, that basically have fixed requirements to meet in terms of income from royalties.

As the price goes down, they have to pump out more of the stuff to meet their revenue requirements.
