So, essentially, it's ad hoc now, but there has been no determination made at this point as to how we'll move forward in the future on that incentive rebate.
Just to kind of dwell on the rebate itself and reframe things from how they were described earlier, I will say that the rebate is essentially to incentivize people to reduce what we don't want: pollution. The less pollution they create, the more they will actually profit from the incentive.
