Now the tax credit on the system is going to be $5,800 dollars. Now keep using mind this is an incentive, which i'm not an accountant, and you may or may not actually receive the tax credit that's based on your federal income tax. Now inflation with the system, like I mentioned it's typically a 2.9% escalator. We're going to exempt you to the 0% bucket. So you would actually never see inflation ever again. What is the inflation rate considered for the system?
