When you're talking interties there's a conversation around the proportion of value to each of the jurisdictions and how that gets funded and the formula around that. In my experience I've seen that to be the most complex part of the equation.

It evolved over what is now close to nine years. That complexity was one of the biggest challenges as they moved forward from a pace.
