Uncertainty in the regulatory regime certainly is one of them. We want to ensure that we have a competitive capital cost to construction. That's one of the barriers on which this government has helped support us within the construction of phase one pipelines, and as you know, Coastal GasLink is a single-source gas pipeline into our Kitimat facility. Hopefully it won't be a barrier for us going forward.
Looking at future growth potential, the biggest opportunities are capital cost of production, the certainty in the regulatory environment as it relates to GHG emissions, and then ensuring we have a competitive position within the global portfolios of our five joint venture partners.
