I could comment as it's a specific area of my expertise, but the issue there I think was related to people becoming comfortable with an alternative approach to using these mobile bunkers. I would have thought that it should have been relatively straightforward to get those cleared and approved through the regulatory agencies that govern the shielding-related issues. But I think it does raise another interesting element, which is the opportunity to work with our regulators to bring innovations forward. We've actually been quite successful with the Canadian Nuclear Safety Commission on bringing innovations forward. Over the past several years we've worked with them on specific technologies and they've helped us bring them forward safely.
