And slide 49 shows what was, what was done in the Senate Finance Committee substitute. So they moved away from this weighted average approach and instead just put in the flat rates for each component of the project. So they took that about 6 cents per MCF rate on the pipeline component and made that a 6.2 cents per 1,000 cubic feet tax rate for phase 1 of the project. And then they took that 10.6 cents per thousand cubic feet weighted average with the capital expenditures weighting and just made that the tax rate once LNG exports began. And so those— the 6.2 and then the 10.6— both of those are roughly taken from the House version of the bill, but made— took out some of the complexity in the calculations.
