Okay. It will be very short.
The main challenge was that we were taking the CETA, which was an agreement with all of the EU members, and trying to convert it to a U.K. agreement only. That did require us to negotiate on some market access issues in particular, which meant separating what we had provided to the EU in CETA and converting that into what we would provide to the U.K. and what they would provide to us in a bilateral transitional agreement. A lot of the issues were very easy, but there are a handful of issues where we do have to have actual negotiations to reach a landing zone.
