The simple answer is that we have contractual commitments and we signed agreements with the customers to deliver a certain scope of work in relation to the contract we signed, and we intend to fulfill those commitments.
The point has also been made that the learning, which is occurring in this early stage of the evolution of this line of business for us, sets the stage for an ongoing revenue stream for AECL, which will stretch decades into the future. So we believe we're laying the groundwork for a very successful line of business for our company.
