 As a landowner, what might be some of the potential benefits you could recognize if shale wells were drilled on or beneath your property? We find with unconventional shale gas development as it's occurring in Pennsylvania and beyond, certainly in the United States where landowners own your minerals. The primary benefit is economic. So landowners, again, if they own their minerals and they're approached by a company, they'll potentially lease those same minerals. They'll receive a payment for that lease as it's put together and structured and signed. And then potentially, if a well is drilled, royalties could accrue. And again, a portion of those would go back to the landowners as well. So again, the primary benefit that most landowners encounter when unconventional natural gas development occurs is in economic.
