In addition to the base budget that we have every year, we've had, as you'll see if you look back, a number of periodic influxes of infrastructure money above and beyond. That permits us to accelerate the renewal or the construction of some of our assets on the ports and airports side. That has been extremely helpful. We've had two influxes in the last five or six years, which has permitted us to accelerate some of our renewal.
In terms of planning ahead, I think our investment plan does a good job of forecasting what we'll need and when. In addition to our regular capital, the additional capital that comes in is sufficient for our requirements.
