Thank you.
One question about the assumption of spending is that you assume we spent $19.3 billion in 2015-16, and then $22.6 billion.... That's $3.3 billion more. By my bad math, that's 17% more, which is about a 6% increase per year: 17% divided by three is 5.8% and something. I'm just curious. That seems like a fairly high annual percentage increase. What went into that assumption?
