Very basically, it is as I said in my opening remarks, which is that if it were delayed until next year for implementation, then the effective start of the treaty will be the calendar year following. If it actually can be passed this year, and the notices to the other jurisdictions, both sent and received, take place, then both of these, the agreement and the arrangement, can take effect for the beginning of 2017. Failing that, it would be the beginning of 2018 or later.
On December 5th, 2016. See this statement in context.
