We have estimated the amount of revenue that will be collected as a result of this tax, and by 2021, that will be about $6 billion, which is almost a quarter of a percentage point of GDP.
Certainly that has an impact on households that are paying that tax and the businesses that are paying that tax, but the amount is very small. Overall, in terms of the impact on GDP, it would be very small. We haven't really done that study, but it would be very small because the amount of revenue generated would be very small.
