Certainly, given the evolution and the progress of the industry, we've had to adapt as well. We couldn't, of course, stay behind and see it as purely clean tech in one area versus another. I'm thinking about aerospace, which is quite an established sector, but in aerospace we're looking at technologies and fuels that are considered under the clean-tech portfolio, among other things.
To your point, Mr. Hoback, yes, we are very much working to adjust and adapt to make sure that wide applications are considered.
